解説 可靠性 in your Level:

At the A1 level, the word 可靠性 (kě kào xìng) might be a bit advanced, as it is an abstract noun. However, you can start by understanding its root, 可靠 (kě kào), which means 'reliable' or 'good.' Think of it as saying something is 'very good' or 'you can trust it.' At this stage, you don't need to use the long word 可靠性 in your own sentences. Instead, focus on the idea: 'This car is good' (这个车很好) or 'This friend is good' (这个朋友很好). Later, you will learn that adding 性 is like adding '-ness' in English. So, 可靠性 is just 'reliable-ness.' For an A1 learner, just remember that if you see this word, it's about things being 'safe' and 'trustworthy.' It's like a 'thumbs up' for a machine or a person. You might see it on a sign for a bank or a car dealership. Don't worry about the grammar yet; just recognize the characters 可靠 (can lean on). If you can lean on something, it won't break!

At the A2 level, you are starting to use more descriptive words. You can move from saying 'good' to saying 可靠 (kě kào). For example, 'My phone is very reliable' (我的手机很可靠). The word 可靠性 (kě kào xìng) is the noun form. You will hear it when people talk about products. If you go shopping for a washing machine, the salesperson might talk about its 可靠性. At this level, you should recognize that 性 makes the word a 'topic' or a 'thing.' Instead of saying 'The car is reliable,' you are saying 'The reliability of the car.' It's a slightly more formal way to speak. You can practice by using it in simple patterns like '...的可靠性很高' (The reliability of ... is very high) or '...的可靠性很低' (The reliability of ... is very low). This helps you sound more like a grown-up speaker rather than just using basic adjectives. Remember: 可 (can) + 靠 (lean) = reliable.

As a B1 learner, 可靠性 (kě kào xìng) is a key vocabulary word for you. You are now expected to discuss topics like technology, work, and society. You should use 可靠性 to evaluate things. For example, in a work meeting, you might say, 'We need to check the reliability of this data' (我们需要检查这些数据的可靠性). You are learning that 可靠性 is not just about being 'good,' but about being 'consistent.' If a friend is reliable, they show up every time. If a car is reliable, it starts every morning. At the B1 level, you should also be able to distinguish 可靠性 from 可信度 (credibility). Use 可靠性 for performance and 可信度 for truth. You can also start using it in more complex sentences with conjunctions, like 'Although the price is high, its reliability makes it worth it' (虽然价格很高，但它的可靠性让它物有所值). This word will appear frequently in news articles and formal emails.

At the B2 level, you should be comfortable using 可靠性 (kě kào xìng) in professional and academic contexts. You should understand that it is a standard term in fields like engineering, statistics, and quality management. You can use it as a subject of complex verbs like 评估 (evaluate), 质疑 (question), or 优化 (optimize). For instance, 'The researcher questioned the reliability of the previous findings' (研究员质疑了之前研究结果的可靠性). You should also be aware of collocations like 运行可靠性 (operational reliability) or 系统可靠性 (system reliability). At this level, you should also be able to use the word in a nuanced way, discussing the trade-offs between speed, cost, and reliability. You might argue that 'In the long run, reliability is more important than short-term profit.' Your vocabulary should also include related terms like 稳定性 (stability) and 耐用性 (durability), and you should know when to choose 可靠性 over them to be most precise.

For C1 learners, 可靠性 (kě kào xìng) is a word you use with precision and stylistic flair. You understand its role in formal logic and scientific methodology. You can discuss 'reliability' in terms of 'inter-rater reliability' or 'test-retest reliability' in a research context. You might use it in a sophisticated argument about the 可靠性 of social media as a news source versus traditional journalism. You are also familiar with idiomatic expressions and high-level synonyms. Instead of just saying 可靠性高, you might use phrases like 无懈可击的可靠性 (impeccable reliability) or 经受住时间的考验 (stood the test of time). Your writing should reflect the ability to integrate this word into complex grammatical structures, such as passive voice or formal conditional statements. You also recognize the cultural nuances—how 可靠性 relates to the Chinese concept of 靠谱 (kào pǔ) in social networks and business relationships, and you can navigate between these registers effortlessly.

可靠性 30秒で

可靠性 (kě kào xìng) means 'reliability' or 'dependability.' It describes how consistent and trustworthy a person, machine, or piece of data is over time.
The word is formed from '可靠' (reliable) and the suffix '性' (-ness). It is a formal noun used extensively in technology, business, and science.
Commonly paired with '高' (high) or '低' (low), it functions as a key metric for quality control and academic rigor in Chinese-speaking environments.
In everyday life, it reflects the 'solidness' of a friend or the durability of a product, often replaced by the informal '靠谱' in casual speech.

The Chinese term 可靠性 (kě kào xìng) is a cornerstone of both everyday conversation and technical discourse. At its heart, it represents the quality of being dependable, consistent, and worthy of trust. In a linguistic sense, it is an abstract noun formed by the adjective 可靠 (reliable/dependable) and the suffix 性 (-ness/quality/nature), which functions similarly to the English suffix '-ity'. When you speak of a person's 可靠性, you are discussing their integrity and the likelihood that they will follow through on their promises. When you apply it to a machine, such as a car or a computer server, you are referring to its ability to perform its required functions under stated conditions for a specified period without failure. This word is indispensable in modern Chinese because it bridges the gap between human character and mechanical performance. For instance, in a job interview, an employer might evaluate the 可靠性 of a candidate's previous work history. In a laboratory, a scientist must ensure the 可靠性 of their experimental data to ensure that the results are not merely a fluke but a consistent reflection of reality. Understanding this word requires recognizing its three constituent parts: 可 (can/able), 靠 (to lean on/rely upon), and 性 (nature/property). Together, they literally mean 'the property of being able to be leaned upon.'

Technical Context: In engineering and manufacturing, 可靠性 is often quantified as the probability of success or the frequency of failure. Engineers spend years testing products to increase this value.
Social Context: In interpersonal relationships, it refers to a person's reputation for being 'solid.' A friend with high 可靠性 is someone who shows up when they say they will.
Academic Context: In statistics and research, it specifically refers to the consistency of a research study or measuring test. If a test yields the same results repeatedly, it has high 可靠性.

这家公司的产品以其卓越的可靠性而闻名于世。 (This company's products are world-famous for their excellent reliability.)

我们需要进一步验证这些实验数据的可靠性。 (We need to further verify the reliability of these experimental data.)

在选择合作伙伴时，可靠性是首要考虑的因素。 (When choosing a partner, reliability is the primary factor to consider.)

这种旧型号的机器虽然速度慢，但其可靠性极高。 (Although this old model machine is slow, its reliability is extremely high.)

软件的可靠性测试是开发过程中不可或缺的一环。 (Reliability testing of software is an indispensable part of the development process.)

Furthermore, 可靠性 is often paired with qualifiers like 极高 (extremely high), 令人怀疑 (doubtful), or 保障 (guarantee). In the age of big data and artificial intelligence, the 可靠性 of algorithms and information sources has become a major topic of public debate. If a news source lacks 可靠性, it is dismissed as 'fake news' or 'rumors.' If a bridge lacks 可靠性, it is a public safety hazard. Thus, the word carries a weight of responsibility and verification. It is not just about a feeling; it is about evidence and consistent performance over time. Whether you are buying a second-hand car or choosing a cloud storage provider, you are essentially making a judgment call on 可靠性. By mastering this word, you gain the ability to participate in discussions about quality control, personal ethics, and scientific rigor in Chinese-speaking environments.

Using 可靠性 correctly involves understanding its role as a noun. It typically functions as the subject or object of a sentence, or as part of an attributive phrase (modifying another noun). Because it represents an abstract quality, it is often used with verbs of assessment like 评估 (evaluate), 测试 (test), 怀疑 (doubt), or 提高 (improve). In formal writing, you will frequently see it in the structure '[Noun] + 的 + 可靠性,' such as 数据的可靠性 (the reliability of data). This section explores the nuances of its grammatical application across various contexts, from the laboratory to the living room.

As an Object of Evaluation: When we want to check if something is reliable, we 'evaluate' or 'test' its 可靠性. For example: '专家们正在评估这项新技术的可靠性' (Experts are currently evaluating the reliability of this new technology).
As a Subject with Adjectives: When describing the state of reliability, we use adjectives like '高' (high), '低' (low), or '差' (poor). For example: '这台发动机的可靠性非常高' (The reliability of this engine is very high).
In Attributive Phrases: It can modify other nouns to indicate a specific type of test or report. For example: '可靠性报告' (reliability report) or '可靠性工程' (reliability engineering).

由于缺乏可靠性，这个理论被科学界否定了。 (Due to a lack of reliability, this theory was rejected by the scientific community.)

我们要不断提高供电系统的可靠性。 (We need to continuously improve the reliability of the power supply system.)

你如何证明这个消息来源的可靠性？ (How do you prove the reliability of this news source?)

In business Chinese, 可靠性 is often discussed in the context of 质量控制 (quality control). A common phrase is 高可靠性设计 (high-reliability design), which is critical in aerospace, medical devices, and automotive industries. When writing a report, you might say, “本研究采用了多种方法来确保测试结果的可靠性” (This study employed various methods to ensure the reliability of the test results). This level of precision is expected in professional settings. Conversely, in a more casual setting, if you are questioning someone's story, you might ask, “这个消息的可靠性有多大？” (How much reliability does this news have?), which is a more polite and slightly more formal way of saying 'Is this true?' or 'Can I trust this?' By varying the verbs and adjectives you pair with 可靠性, you can express a wide range of nuances regarding trust and performance.

You will encounter 可靠性 in a variety of real-world scenarios in China and other Chinese-speaking regions. It is a word that spans the gap between the blue-collar workshop and the high-tech boardroom. In the media, it is a favorite term for tech reviewers comparing smartphones or electric vehicles. On the news, it appears during discussions of national infrastructure, such as high-speed rail safety or the stability of the power grid. In the academic world, it is the standard term for 'reliability' in research methodologies. Understanding the context helps you grasp the specific weight the word carries in each situation.

Product Reviews and Tech Media: Tech influencers on platforms like Bilibili or Weibo often debate the 可靠性 of new hardware. They might say, '这款折叠屏手机的可靠性还需要时间验证' (The reliability of this folding screen phone still needs time to be verified).
Corporate Meetings: During project updates, managers focus on 可靠性 as a key performance indicator (KPI). '我们的首要任务是提高服务器的可靠性' (Our primary task is to improve the reliability of the servers).
Scientific and Academic Papers: In the 'Methodology' section of a thesis, you will almost always find a discussion on 可靠性 (reliability) and 有效性 (validity).

新闻播报：为了保障春运安全，铁路部门对所有列车进行了可靠性检查。 (News broadcast: To ensure safety during the Spring Festival travel rush, the railway department conducted reliability checks on all trains.)

办公室对话：这个供应商的可靠性一直是个问题，我们得换一家。 (Office dialogue: This supplier's reliability has always been an issue; we need to switch to another one.)

If you are traveling in China, you might see 可靠性 in advertisements for home appliances or automobiles. A brand like Midea or Haier might emphasize the 可靠性 of their washing machines to appeal to practical consumers who value longevity over flashy features. In the financial sector, when discussing investment products or the 可靠性 of a credit rating, the word takes on a legal and fiscal weight. It implies that the numbers provided are not just estimates but are backed by solid evidence. Even in everyday gossip, if someone says, “那个人说话的可靠性不高” (That person's words don't have much reliability), they are essentially warning you that the person is a habitual liar or exaggerator. Thus, whether you are reading a technical manual, a financial report, or just chatting with a colleague, 可靠性 is a vital concept for judging the world around you.

Learning to use 可靠性 correctly requires navigating several common pitfalls. Many learners confuse it with similar-sounding words or use the wrong grammatical structure. Because Chinese adjectives can often function as nouns in certain contexts, students sometimes forget to add the 性 suffix when they want to speak about 'reliability' as a conceptual property. Furthermore, there is a nuance between 'trustworthiness' and 'consistency' that can lead to choosing the wrong word in specific scenarios.

Confusing Adjective and Noun: Mistake: '这个机器的可靠很好' (The reliable of this machine is good). Correct: '这个机器的可靠性很好' or '这个机器很可靠'. You must use the noun form with '的'.
Confusing with '可信度' (Credibility): 可靠性 is about performance and consistency. '可信度' is about whether something can be believed. You check the 可靠性 of a car, but the '可信度' of a rumor.
Overusing it for People: While you can say '一个人的可靠性,' it sounds a bit clinical or like a performance review. In casual conversation, it's more natural to say '他这人靠不靠谱？' (Is this guy reliable/dependable?).

错误：数据的可靠是非常重要的。 (Wrong: The reliable of data is very important.)
正确：数据的可靠性是非常重要的。 (Correct: The reliability of data is very important.)

Another mistake is using 可靠性 when you actually mean 稳定性 (stability). While a reliable system is often stable, 稳定性 refers specifically to the ability to remain unchanged or resist disturbance, whereas 可靠性 refers to the ability to perform a task correctly over time. For example, a unstable bridge might still be 'reliable' in the sense that it hasn't collapsed yet, but you wouldn't want to use it! Conversely, a very stable computer system might have low 可靠性 if it consistently produces the wrong mathematical results. Pay attention to the specific type of 'goodness' you are trying to describe. Finally, avoid using 可靠性 as a verb. You cannot '可靠性' something. You must 验证 (verify), 评估 (evaluate), or 保障 (guarantee) the 可靠性.

To truly master 可靠性, you must understand its synonyms and how they differ in nuance. Chinese has a rich vocabulary for 'trust' and 'dependability,' and choosing the right word depends on whether you are talking about a person's character, a machine's performance, or the truth of a statement. Below, we compare 可靠性 with its closest linguistic relatives.

可靠性 vs. 可信度 (kě xìn dù): 可靠性 is reliability (performance/consistency). '可信度' is credibility (believability). Use '可信度' for news, rumors, or witnesses. Use 可靠性 for tools, data, and mechanical systems.
可靠性 vs. 稳定性 (wěn dìng xìng): 可靠性 is about whether it works as intended. '稳定性' is about whether it remains steady and doesn't fluctuate. A system can be stable (doesn't crash) but not reliable (gives wrong answers).
可靠性 vs. 准确性 (zhǔn què xìng): '准确性' means accuracy. A clock that is always 5 minutes fast is 可靠 (it's consistent), but not '准确' (it's not showing the correct time).

虽然这个实验结果具有很高的可靠性，但其准确性仍有待提高。 (Although this experimental result has high reliability, its accuracy still needs to be improved.)

Other alternatives include 安全性 (safety) when the lack of reliability leads to danger, and 有效性 (validity) in scientific contexts. For example, a medical test must have both 可靠性 (you get the same result twice) and 有效性 (it actually detects the disease it claims to). When discussing people, you might use 诚实 (honesty) or 稳重 (steady/mature). However, 可靠性 remains the most versatile and professional term for describing the abstract quality of being able to be counted on. By understanding these distinctions, you can avoid the 'one-word-fits-all' trap and speak Chinese with the precision of a native speaker.

How Formal Is It?

豆知識

The character '靠' (kào) contains the '告' (to tell) radical and '非' (wrong/not). Etymologically, it was once related to contradicting or opposing, but it evolved to mean 'leaning' because when you lean on something, you are in close contact with it.

発音ガイド

UK /kʰɤ˨˩˦ kʰɑʊ̯˥˩ ɕiŋ˥˩/

US /kʰɤ˨˩˦ kʰɑʊ̯˥˩ ɕiŋ˥˩/

In Chinese, each syllable has its own tone, but 'kào' and 'xìng' are emphasized due to their sharp falling tones.

韻が合う語

性 (xìng) rhymes with 定 (dìng - fixed) 性 (xìng) rhymes with 命 (mìng - life) 性 (xìng) rhymes with 硬 (yìng - hard) 靠 (kào) rhymes with 跑 (pǎo - run) 靠 (kào) rhymes with 老 (lǎo - old) 靠 (kào) rhymes with 宝 (bǎo - treasure) 可 (kě) rhymes with 车 (chē - car) 可 (kě) rhymes with 乐 (lè - happy)

よくある間違い

Pronouncing 'kě' as a flat tone instead of dipping.
Merging the two falling tones of 'kào' and 'xìng' into one long slide.
Mispronouncing 'xìng' as 'xīn' (forgetting the 'g' sound).
Using the wrong tone for 'kào', making it sound like 'kǎo' (to examine).
Stress is often misplaced on the first syllable by English speakers.

ヒント

Noun Usage

Always use '的' when describing the reliability of something: [Object] + 的 + 可靠性.

Informal Alternative

Use '靠谱' (kào pǔ) in daily life to sound more natural and less like a textbook.

Formal Contexts

In professional reports, use '可靠性' alongside '有效性' (validity) and '稳定性' (stability) for a comprehensive evaluation.

Tone Mastery

Practice the transition from the dipping tone of 'kě' to the falling tone of 'kào' to avoid sounding flat.

The Root 'Kao'

Remember that '靠' means 'to lean.' If you can lean on it, it's reliable!

チャレンジ

Try to use '可靠性' in three different contexts today: once about a person, once about a tool, and once about information.

語源

The word is a modern compound. '可' (kě) dates back to ancient oracle bones, meaning 'to be able to.' '靠' (kào) originally meant 'to lean against' or 'to approach.' '性' (xìng) refers to 'nature' or 'innate quality.'

元の意味： The combination suggests a nature or quality that allows one to lean against or depend upon it.

Sino-Tibetan (Mandarin Chinese).

文化的な背景

Be careful not to sound too robotic when using '可靠性' with close friends; '靠谱' is much warmer.

In English, 'reliability' is often used interchangeably with 'dependability,' but in Chinese, '可靠性' is slightly more formal than 'dependability.'
