解説采样 in your Level:

At the A1 level, you don't need to use '采样' (cǎiyàng) very often in your own speaking, but it is good to recognize it. Think of it as 'taking a small piece to look at.' You might see it in a hospital or a science museum. The word is made of 'cǎi' (to pick, like picking a flower) and 'yàng' (a sample or kind). So, it's like 'picking a sample.' For now, just remember that it is a formal word used in science or medicine. If you see a sign that says '采样点' (cǎiyàng diǎn), it just means 'Place to take a sample/test.' You don't need to worry about the complex math or science behind it yet. Just know that it involves collecting something small to represent something big. If you are talking about food, don't use this word! Use '尝' (cháng) instead. '采样' is for serious things like blood tests or water tests. It is a very polite and professional word.

At the A2 level, you might start seeing '采样' (cǎiyàng) in news reports or health-related contexts. It's a verb and a noun. It means 'to sample' or 'sampling.' You can use it when talking about simple scientific experiments or medical tests. For example, if you are at a clinic, the nurse might perform '采样.' You can understand it as a more professional version of '拿样本' (ná yàngběn - take a sample). It's important to notice that this word is used in specific places like labs, hospitals, or when talking about technology. You might hear it in phrases like '核酸采样' (hésuān cǎiyàng), which was very common during the pandemic for virus testing. When you use it, you sound more educated and precise. Try to remember it as a 'technical collection' word. It's not for picking up your toys or gathering your friends; it's for gathering data or specimens.

At the B1 level, you should be able to use '采样' (cǎiyàng) in technical or professional discussions. You'll recognize that it's a key term in statistics, environmental science, and digital media. You should understand the structure '对...进行采样' (to perform sampling on...). This is a very common way to use the word in formal writing or speaking. For example, '我们需要对水源进行采样' (We need to sample the water source). You should also be aware of '采样率' (cǎiyàng lǜ - sampling rate) if you are interested in music or computers. At this level, you should be careful not to confuse '采样' with '样本' (the actual object) or '采集' (general collection). '采样' implies a specific method is being used to ensure the sample represents the whole. It's a very useful word for describing research processes or technical workflows. You will also see it in social science contexts, such as when a survey 'samples' a certain number of people from a city to understand their opinions.

At the B2 level, you should have a firm grasp of '采样' (cǎiyàng) and its nuances across different fields. You should be able to discuss the methodology of a study using terms like '随机采样' (suíjī cǎiyàng - random sampling) or '分层采样' (fēncéng cǎiyàng - stratified sampling). You understand that in the context of digital signals, 采样 refers to the discretization of continuous signals, a fundamental concept in engineering and computer science. You can use the word to explain why a certain piece of research is valid or invalid based on its sampling methods. For example, you might argue that a '采样偏差' (sampling bias) led to incorrect conclusions. You should also be comfortable using 采样 in creative contexts, such as music production, where it refers to using a portion of an existing sound recording. Your usage should reflect an understanding of the word's formal register, and you should be able to switch between 采样, 抽样, and 采集 depending on the specific technical requirements of the topic.

At the C1 level, '采样' (cǎiyàng) becomes a tool for precise academic and professional communication. You are expected to understand its implications in complex systems, such as Monte Carlo sampling in mathematics or high-frequency sampling in financial markets. You can discuss the trade-offs between '采样频率' (sampling frequency) and data processing power. In a medical or biological context, you can describe the specific protocols for '采样保存' (sample preservation) and '采样运输' (sample transport). Your vocabulary should include related technical terms like '欠采样' (undersampling) and '过采样' (oversampling), and you should be able to explain their effects on data integrity (such as aliasing in signal processing). You can also use the word metaphorically or in high-level business strategy, such as 'sampling' market sentiment through various data points. Your command of the word allows you to navigate professional environments where precision is paramount, and you can distinguish the subtle differences in connotation between 采样 and its synonyms in highly specialized literature.

At the C2 level, you possess a near-native understanding of '采样' (cǎiyàng), including its historical development and its most abstract applications. You can engage in deep technical debates about sampling theory, Nyquist–Shannon sampling theorem (奈奎斯特-香农采样定理), and the philosophical implications of representing a continuous reality through discrete samples. You are sensitive to the stylistic choices of using 采样 versus 抽样 in different academic traditions (e.g., Soviet-influenced vs. Western-influenced terminology in certain Chinese scientific fields). You can write professional-grade research papers or technical specifications that use 采样 with perfect accuracy and sophisticated phrasing. You also understand the legal and ethical dimensions of sampling, such as '采样版权' (sampling copyright) in the music industry or '隐私采样' (privacy-preserving sampling) in big data. Your use of the word is indistinguishable from that of a highly educated native professional, and you can use it to articulate complex ideas with clarity and authority.

采样 30秒で

采样 (cǎiyàng) means 'sampling' in technical, medical, and scientific contexts.
It is used as both a verb (to sample) and a noun (the sampling process).
Commonly seen in medical testing (COVID tests) and digital audio (sampling rate).
It implies a formal, methodical collection rather than a casual one.

The Chinese term 采样 (cǎiyàng) is a compound word that functions as both a verb and a noun. At its core, it refers to the systematic process of selecting a representative portion from a larger group or substance to analyze its properties. In modern Chinese, this word has exploded in usage across diverse fields, ranging from medical diagnostics and environmental science to digital music production and big data analytics. The first character, 采 (cǎi), means to gather, pick, or collect, while the second, 样 (yàng), refers to a sample, pattern, or model. Together, they describe the act of 'gathering a sample.'

Scientific Context: In laboratory settings, 采样 is the standard term for taking specimens. Whether it is a biologist taking a water sample from a polluted river or a geologist collecting rock fragments, the term denotes a methodical approach to collection that ensures the sample is untainted and representative of the source.
Medical Context: Post-2020, this word became a household name in China due to mass testing. The phrase 核酸采样 (hésuān cǎiyàng - nucleic acid sampling) refers to the process of swabbing for a virus. It describes the physical action of the medical professional taking the biological material.
Digital Context: In audio engineering and signal processing, 采样 refers to 'sampling rate' (采样率). This is the process of converting an analog signal into a digital format by taking discrete measurements of the sound wave at set intervals. If you are a fan of hip-hop or electronic music, you will hear artists talk about 采样 when they take a snippet of an old record to use in a new track.

为了确保实验的准确性，我们需要在不同的时间点进行采样。 (To ensure the accuracy of the experiment, we need to perform sampling at different time points.)

When people use 采样, they are usually implying a level of precision. In statistical surveys, 采样 is the bridge between a small group and a massive population. Without proper 采样, the data collected would be biased and useless. Therefore, when you hear this word in a business meeting or a news report, it signals that the information being discussed is based on evidence gathered through a specific methodology. In the world of Big Data, 采样 is a crucial step in data cleaning and preprocessing, where engineers select a subset of data to train machine learning models. This prevents the systems from being overwhelmed by too much information while still allowing them to learn the underlying patterns. In summary, 采样 is the act of choosing a small part to understand the big picture, a concept that is fundamental to modern science and technology.

Using 采样 correctly requires understanding its role as both a noun and a verb. As a verb, it often follows an object or is used within a prepositional phrase. As a noun, it frequently appears in technical descriptions or as part of a compound noun. Let's explore the various grammatical structures where this word shines.

Verb Structure: 对...进行采样: This is the most common formal way to say 'to perform sampling on something.' Example: 工程师正在对土壤进行采样 (The engineer is sampling the soil).
As a Modifier: 采样+Noun: When 采样 acts as an adjective/modifier, it describes tools or metrics. For instance, 采样点 (cǎiyàng diǎn) means 'sampling point' or 'collection site.' 采样工具 (cǎiyàng gōngjù) means 'sampling tools.'

这个音频文件的采样率非常高，所以音质很清晰。 (The sampling rate of this audio file is very high, so the sound quality is very clear.)

In a B1 level context, you might encounter 采样 in discussions about environmental protection or health. For example, if you are reading a news article about air quality, you might see the phrase '空气采样' (air sampling). This refers to the machines that 'breathe' in air to test for pollutants. In these sentences, 采样 is often the subject of the sentence, performing the action of providing data.

医生建议在空腹状态下进行血液采样。 (The doctor recommends blood sampling while fasting.)

Furthermore, 采样 can be used in the passive voice with '被' (bèi), although it is less common. For example, '样本已被采样完毕' (The samples have been completely collected). In the world of statistics, '随机采样' (suíjī cǎiyàng - random sampling) is a fixed phrase that describes a method where every member of a population has an equal chance of being selected. This is vital for avoiding bias in research. Mastering the use of 采样 involves understanding that it is a 'process-oriented' word—it emphasizes the method of collection rather than just the objects themselves.

Understanding where you will encounter 采样 helps in grasping its register. It is not a word you would typically use while chatting with friends at a bar, unless those friends are audio engineers or laboratory technicians. However, in the professional world and public service announcements, it is ubiquitous.

Hospitals and Testing Centers: In China, during any health screening, you will see signs pointing to the 采样区 (Sampling Area). Staff will ask you to '配合采样' (cooperate with the sampling). It sounds more clinical and professional than just saying 'taking a test.'
Music and Creative Studios: If you watch a documentary about a famous music producer, they might say, '我在这首歌中采样了一段古典音乐' (I sampled a piece of classical music in this song). Here, it refers to the creative act of repurposing sound.

这个湖泊的水质采样工作每季度进行一次。 (The water quality sampling of this lake is conducted once every quarter.)

In the news, 采样 frequently appears in reports about social trends or economic data. When the government reports on the 'average salary,' they will mention the 采样范围 (sampling range) to explain which cities or industries were included in the calculation. This gives the data credibility. In the tech industry, specifically in Artificial Intelligence, 采样 is a daily topic. Developers discuss 'downsampling' (下采样) and 'upsampling' (上采样) when processing images to change their resolution or prepare them for neural networks.

Lastly, in the field of manufacturing, 采样 is part of 'Quality Control' (质量控制). Before a batch of products leaves a factory, workers perform '抽样检查' (sampling inspection). While 抽样 is slightly more common for physical products, 采样 is used when the process involves more technical measurement, like testing the chemical composition of a plastic batch. By listening for 采样 in these specific contexts, you can better understand the level of technicality in a Chinese conversation or document.

For English speakers, the primary difficulty with 采样 lies in its specificity. In English, the word 'sample' can be used in many ways, but in Chinese, different words are used depending on whether you are talking about the act, the object, or the experience.

Mistake 1: Using 采样 for 'trying food': If you say '我可以采样这个蛋糕吗？' (Can I sample this cake?), a Chinese speaker will think you want to take it to a lab for chemical analysis. Use 品尝 (pǐncháng) or 尝尝 (chángcháng) for tasting food.
Mistake 2: Confusing 采样 with 样本: 采样 is the action or the process. 样本 (yàngběn) is the noun for the physical sample itself. You '采样' to get a '样本'.

错误：我们需要更多的采样来完成研究。
正确：我们需要更多的样本来完成研究。 (Correction: Use '样本' when referring to the quantity of items needed.)

Another nuance is the difference between 采样 and 抽样 (chōuyàng). While they are often interchangeable in statistics, 采样 is preferred in technical, digital, and biological contexts, while 抽样 is preferred in social sciences and quality control. For example, 'random sampling' is usually 随机抽样 in a math book, but 'audio sampling' is always 音频采样. Using the wrong one won't always make you misunderstood, but it will sound slightly 'off' to a native ear.

Finally, be careful with the word 采集 (cǎijí). 采集 means to collect or gather in a more general sense, often used for data collection (数据采集) or gathering wild plants. 采样 specifically implies that what you are gathering is a *representative sample* of a larger whole. If you are gathering all the data available, use 采集. If you are only taking a small piece to represent the rest, use 采样. Understanding these boundaries will help you sound much more professional and precise in your Chinese communication.

To truly master 采样, you must see how it fits into the ecosystem of 'collection' words in Chinese. Here is a comparison with its closest relatives.

抽样 (chōuyàng): Focuses on the 'drawing' or 'extracting' (抽) aspect. It is the standard term for statistical sampling. Use this when talking about surveys, polls, or selecting items for inspection from a factory line.
采集 (cǎijí): A broader term for 'collecting.' It is used for gathering information, biological specimens (in a general sense), or natural resources. It doesn't necessarily imply that the collection is a representative 'sample.'
取样 (qǔyàng): Very similar to 采样, but '取' means 'to take.' This is often used in chemistry and industrial processes. It is slightly more physical than 采样.

虽然采样和抽样在很多情况下可以互换，但在数字信号处理中，我们只使用“采样”。 (Although sampling and statistical sampling are interchangeable in many cases, in digital signal processing, we only use 'sampling' [采样].)

When deciding which word to use, consider the 'feel' of the action. If the action feels like a scientific procedure, 采样 is likely the best choice. If it feels like a simple gathering of things, 采集 is better. If it involves a mathematical probability, 抽样 is the winner. For example, if you are 'collecting' user data from an app, you are doing 数据采集. If you take a subset of that data to test a new algorithm, you are doing 数据采样.

In summary, 采样 is a high-utility word for anyone dealing with science, technology, or modern administration in China. By comparing it to 抽样 and 采集, you can see that it occupies a specific niche of 'technical representative collection.' As you progress to higher levels of Chinese, being able to distinguish between these synonyms will be a key marker of your fluency.

ヒント

Use with '进行'

To sound more natural in a professional setting, use the phrase '进行采样' (perform sampling) instead of just '采样' as a verb.

Don't confuse with 采集

Remember: 采集 is for gathering everything or general data; 采样 is for taking a representative piece.

Tone Accuracy

The third tone in 'cǎi' must be clear. If you say it with a first tone, it sounds like '猜' (to guess).

Radical Awareness

The wood radical (木) in '样' reminds you that the original 'pattern' or 'sample' was made of wood.

Medical Politeness

In a hospital, using '采样' shows you understand the technical process and is more polite than '抽血' (drawing blood).

Audio Terms

If you are into music, learn '采样率' (sampling rate) and '采样深度' (bit depth) together.

Environmental Context

When reading about ecology, '采样' is usually paired with '土壤' (soil) or '水质' (water quality).

Random Sampling

Always pair '随机' (random) with '采样' when discussing unbiased data collection.

Food Sampling

Never use '采样' at a grocery store sample station. Use '试吃' (shìchī) instead.

News Reports

When you hear '采样' on the news, pay attention to the '范围' (range) they mention to understand the data's context.

記憶術

Imagine a hand (采) picking a small piece of a large cake (样) to test if it's tasty. That's 采样!

視覚的連想

Visualize a scientist in a lab coat dipping a test tube into a river. The action of dipping is 'cǎi' and the water in the tube is the 'yàng'.

Word Web

采样 (Sampling) 数据 (Data) 实验 (Experiment) 医院 (Hospital) 音乐 (Music) 水质 (Water quality) 结果 (Result) 准确 (Accurate)

チャレンジ

Try to use '采样' in a sentence about your favorite music or a health checkup you had.

語源

The word 采样 is composed of two ancient Chinese characters. '采' (cǎi) originally depicted a hand picking fruit or leaves from a tree, symbolizing collection. '样' (yàng) originally referred to a 'pattern' or 'shape' made of wood. In modern technical language, they were combined to translate the Western scientific concept of 'sampling.'

元の意味： To gather a pattern or model.

Sino-Tibetan (Chinese)

文化的な背景

Be mindful when discussing 'sampling' in medical contexts, as it can be a sensitive topic related to the pandemic history.

In English, 'sampling' is often associated with free food at Costco, but in Chinese, 采样 is much more formal.

よくある質問

No, 采样 is too technical for that. For perfume, use '试用' (shìyòng - to try out) or '闻一闻' (wén yī wén - to smell). 采样 would imply you are analyzing the chemical structure of the perfume in a lab.

Since 2020, yes. Because of mass health testing, almost everyone in China knows this word. Before that, it was mostly used by scientists and engineers.

In many contexts like statistics, they are interchangeable. However, 采样 is the standard term for digital signals (audio/video) and biological specimens (swabs), while 抽样 is the standard term for social surveys and quality control in factories.

Yes, it is frequently used as a noun. For example, '采样的结果' (the results of the sampling) or '高频率采样' (high-frequency sampling).

It is '采样率' (cǎiyàng lǜ). This is a very common term in computer science and music production.

Yes! When a producer uses a piece of another song, it's called 采样. For example: '这首歌采样了迈克尔·杰克逊的作品' (This song sampled Michael Jackson's work).

It literally means 'sampling point.' In recent years, it specifically referred to the booths or tents where people went to get tested for viruses.

No. Use '采' (cǎi) or '摘' (zhāi) for picking flowers. 采样 is only for taking a sample for a specific purpose like research.

Yes, it is a formal and technical term. In a casual conversation about non-technical things, you would rarely hear it.

It means 'random sampling.' This is a core concept in statistics where every item in a group has an equal chance of being picked.
