설명 定律 in your Level:

At the A1 level, the word 定律 (dìnglǜ) might seem a bit advanced, but you can understand it as a 'super rule.' Think of the rules you have in school or in a game. Those are rules that people made up. Now, think about rules that the world made up, like 'what goes up must come down.' These are called 定律. Even if you don't use this word every day, you will see it in books about science. The first character 定 (dìng) means 'fixed' or 'decided.' The second character 律 (lǜ) means 'rule.' So, it is a rule that is fixed and cannot be changed by people. You can remember it by thinking about the 'Law of Gravity.' In Chinese, that is a 定律. At this stage, just recognize that it is a noun for very important, unchanging rules of nature. Don't worry about using it in complex sentences yet. Just know that when a Chinese person says 定律, they are talking about something very serious and true.

At the A2 level, you are starting to learn more formal nouns. 定律 (dìnglǜ) is a great word to add to your vocabulary for talking about facts. While you might use 规则 (guīzé) for simple rules like 'no running in the hall,' you should use 定律 when talking about science or big truths. For example, if you are learning about the weather or how machines work, you might hear the word 定律. A common example is 'Murphy's Law' (墨菲定律), which many people know. It's the idea that if something can go wrong, it will. Using this word makes you sound more educated. Remember that you can't 'break' a 定律 like you break a window; it's more like a fact of life. You can use it with simple verbs like '有' (yǒu - to have/there is) or '是' (shì - to be). For instance, '这是一种定律' (This is a kind of law). Focus on recognizing it in science contexts.

At the B1 level, you should be able to distinguish between different types of 'laws' and 'rules.' This is where 定律 (dìnglǜ) becomes really useful. You should now understand that 定律 is for scientific laws (like Newton's laws) and objective truths. You should avoid using it for government laws (use 法律 instead) or game rules (use 规则 instead). At this level, you can start using 定律 in sentences to explain why things happen. For example, '根据能量守恒定律...' (According to the law of conservation of energy...). You might also encounter it in business contexts, like the '80/20 Law' (二八定律). This word helps you move from talking about personal opinions to talking about objective facts. You should also start noticing the measure words used with it, like '条' (tiáo). Being able to use 定律 correctly shows that you understand the difference between human-made systems and the natural order of things.

At the B2 level, you should use 定律 (dìnglǜ) with confidence in academic and professional discussions. You are expected to know specific scientific laws in Chinese, such as 万有引力定律 (Universal Gravitation) or 矛盾定律 (Law of Contradiction). You should also understand how 定律 is used metaphorically in literature and social science to describe 'inevitable outcomes.' For example, a historian might talk about the '定律 of dynastic change.' You should be able to use verbs like '揭示' (jiēshì - to reveal), '遵循' (zūnxún - to follow), and '违背' (wéibèi - to violate) in combination with 定律. Your understanding should also include the nuance between 定律 and 规律 (guīlǜ). While 规律 is a pattern you observe, 定律 is the formal statement of that pattern as a rule. In a debate or a presentation, using 定律 allows you to ground your arguments in established principles, giving your speech more authority and weight.

At the C1 level, your use of 定律 (dìnglǜ) should be precise and nuanced. You should be able to discuss the philosophical implications of 'laws'—whether they are discovered or invented by humans. You will encounter this word in complex texts about theoretical physics, economics, and philosophy. You should be comfortable with idiomatic expressions and fixed phrases like '铁的定律' (an ironclad law) to describe something that is absolutely certain. You should also be able to critique the application of the word; for example, arguing that a certain economic 'law' is actually just a temporary 'trend' (规律). At this level, you can use 定律 to discuss abstract concepts like the 'laws of logic' or the 'laws of aesthetics.' Your ability to use this word in a variety of registers—from a casual joke about 'Murphy's Law' to a formal analysis of 'Thermodynamics'—demonstrates a deep mastery of Chinese vocabulary and cultural context.

At the C2 level, 定律 (dìnglǜ) is a tool for sophisticated intellectual discourse. You understand the epistemological status of a '定律' within the philosophy of science—how it differs from a hypothesis or a theory. You can engage in high-level debates about whether social sciences can truly have '定律' in the same way that physical sciences do. You are familiar with historical shifts in how certain 定律 were understood and eventually refined or replaced (like the shift from Newtonian to Einsteinian physics). You can use the word with ultimate precision in writing, choosing it over synonyms like 法则 or 原理 to convey exactly the right level of formality and ontological commitment. Whether you are writing a scientific paper, a legal brief that touches on forensic evidence, or a philosophical treatise, you use 定律 to define the boundaries of what is considered settled, immutable truth versus what is still subject to human interpretation.

定律 30초 만에

A formal noun meaning 'law' in a scientific or objective sense.
Used for unchanging principles like physics, math, and universal truths.
Distinguished from 法律 (legal law) and 规则 (procedural rules).
Commonly paired with scientist names (e.g., Newton's Law) or fields (e.g., economic law).

The Chinese word 定律 (dìnglǜ) is a formal noun that translates most directly to "law" in a scientific, mathematical, or objective sense. Unlike the word for legal laws (法律 - fǎlǜ), which are created by governments and can be changed by legislation, a 定律 represents an immutable principle of the universe or an established rule that describes how things consistently behave under specific conditions. It is the bedrock of scientific inquiry and logical reasoning in the Chinese-speaking world.

Scientific Context: In physics and chemistry, this word is used to name fundamental principles. For example, Newton's Laws of Motion are known as 牛顿运动定律 (Niúdùn yùndòng dìnglǜ). It implies a relationship that has been proven through observation and experimentation and is considered universally true within its domain.
Social and Psychological Context: Beyond hard sciences, 定律 is often applied to social observations that seem to hold true universally, such as Murphy's Law (墨菲定律 - Mòfēi dìnglǜ) or the Pareto Principle (二八定律 - èrbā dìnglǜ). Here, it suggests a pattern so consistent that it feels like a law of nature.
Philosophical Nuance: Philosophically, using 定律 conveys a sense of inevitability. When a speaker describes a situation as following a certain 定律, they are suggesting that the outcome is predictable and unavoidable based on the inherent nature of the system involved.

科学的研究离不开对自然定律的探索和总结。
(Scientific research is inseparable from the exploration and summary of natural laws.)

无论你是否相信，万有引力定律都在起作用。
(Whether you believe it or not, the law of universal gravitation is at work.)

墨菲定律告诉我们，事情如果有变坏的可能，就一定会变坏。
(Murphy's Law tells us that if anything can go wrong, it will.)

能量守恒定律是物理学的基本基石之一。
(The law of conservation of energy is one of the fundamental cornerstones of physics.)

这个市场的波动似乎并不遵循任何已知的经济定律。
(The fluctuations of this market do not seem to follow any known economic laws.)

To use 定律 correctly, remember that it implies a sense of "fixedness." The character 定 (dìng) means fixed, decided, or stable, while 律 (lǜ) refers to a rule or law. Therefore, a 定律 is a rule that is fixed and does not change. If you are talking about a rule in a game or a temporary regulation in a company, you should use 规则 (guīzé) instead. If you are talking about a pattern or trend that is generally true but might have exceptions, 规律 (guīlǜ) is more appropriate. Use 定律 when you want to sound authoritative, scientific, or when referring to principles that are considered absolute truths in their respective fields.

Using 定律 (定律) effectively requires understanding its role as a formal noun. It usually functions as the object of a verb like "遵循" (zūnxún - to follow), "发现" (fāxiàn - to discover), or "违背" (wéibèi - to violate/go against). It is also frequently modified by proper nouns (names of scientists) or specific fields of study.

Verb + 定律: Common verbs paired with 定律 include 验证 (yànzhèng - verify), 应用 (yìngyòng - apply), and 揭示 (jiēshì - reveal). For example: "科学家们正试图验证这一物理定律。" (Scientists are trying to verify this physical law.)
Adjective/Noun + 定律: You will often see it preceded by its specific name. Examples: 黄金定律 (huángjīn dìnglǜ - Golden Rule), 铁的定律 (tiě de dìnglǜ - Ironclad law/unbreakable rule), 自然定律 (zìrán dìnglǜ - Natural law).
Sentence Patterns: A common pattern is "[Subject] 符合 [Specific] 定律" ([Subject] conforms to [Specific] law). This is used to explain why something happened or to predict an outcome.

他的成功似乎打破了某种职场定律。
(His success seems to have broken some kind of workplace law.)

我们必须遵循自然界的客观定律。
(We must follow the objective laws of nature.)

摩尔定律预测了计算机芯片性能的快速增长。
(Moore's Law predicted the rapid growth of computer chip performance.)

这条定律在极端情况下可能不再适用。
(This law may no longer be applicable in extreme cases.)

每一个伟大的发现都始于对现有定律的质疑。
(Every great discovery begins with questioning existing laws.)

In summary, 定律 is used when describing fixed, universal, or highly consistent principles. It is the language of textbooks, research papers, and deep philosophical discussions. When you use it, you are emphasizing the reliability and unchanging nature of the rule you are discussing. It creates a tone of seriousness and factual certainty.

Understanding the specific environments where 定律 (dìnglǜ) is spoken or written helps in mastering its usage. You won't hear it in a casual conversation about buying groceries, but you will encounter it frequently in the following scenarios:

Educational Environments: From middle school through university, 定律 is a staple of science classrooms. Teachers will say, "请记住这三条牛顿定律" (Please remember these three Newton's laws). It is the primary word used in textbooks for physics, chemistry, and mathematics.
Science Documentaries and Podcasts: Media that explains the universe frequently uses 定律. Narrators might describe the "定律 of thermodynamics" or the "定律 of planetary motion." It provides an air of authority and scientific precision to the narration.
Business and Personal Growth Seminars: Motivational speakers and business consultants love using "laws" to make their advice sound more robust. Phrases like "吸引力定律" (Law of Attraction) or "帕金森定律" (Parkinson's Law) are common in this register to suggest that success follows specific, predictable rules.

在今天的物理课上，我们将学习热力学第一定律。
(In today's physics class, we will learn the first law of thermodynamics.)

纪录片向我们展示了宇宙运行的奇妙定律。
(The documentary showed us the wonderful laws of the universe's operation.)

许多成功学书籍都提到了“吸引力定律”。
(Many self-help books mention the "Law of Attraction.")

这并不是某种不可逾越的定律，而只是一个普遍的现象。
(This is not some insurmountable law, but just a common phenomenon.)

在辩论中，引用科学定律可以增强论点的说服力。
(In a debate, citing scientific laws can enhance the persuasiveness of an argument.)

Furthermore, 定律 appears in high-level literature and philosophical texts where the author discusses the "laws of history" (历史定律) or the "laws of life" (人生定律). In these cases, it moves away from literal science and becomes a metaphor for the deep, underlying structures that govern human existence. Whether in a lab or a library, 定律 is the word for the rules that don't bend.

While 定律 (dìnglǜ) is a straightforward word, learners often confuse it with other terms that mean "rule" or "law." Avoiding these pitfalls will make your Chinese sound more natural and precise.

Confusing 定律 with 法律 (fǎlǜ): This is the most common mistake. 法律 refers to the legal system, statutes, and acts passed by a government (e.g., traffic laws, criminal law). 定律 refers to scientific or objective laws (e.g., gravity). You cannot "break" a 定律 in the legal sense; you can only disprove it or observe its effects.
Confusing 定律 with 规则 (guīzé): 规则 are man-made rules for games, companies, or social interactions. They are arbitrary and can be changed easily. If you say "The定律 of the game," it sounds like the game is a fundamental force of nature, which is usually incorrect.
Confusing 定律 with 规律 (guīlǜ): This is a subtle but important distinction. 规律 refers to patterns, trends, or regularities (e.g., the pattern of the seasons, the pattern of economic cycles). 定律 is more rigorous and suggests a fixed formula or a named scientific principle. Use 规律 for things that happen regularly, and 定律 for the underlying scientific reason why they must happen.

错误：他因为违反交通定律被罚款了。
正确：他因为违反交通法律/规则被罚款了。
(Correction: He was fined for violating traffic laws/rules, not scientific laws.)

错误：足球比赛有很多复杂的定律。
正确：足球比赛有很多复杂的规则。
(Correction: Football has rules, not scientific laws.)

Another minor mistake is misusing the measure word. While '个' is understood, using '条' (tiáo) or '项' (xiàng) shows a higher level of proficiency. Finally, avoid using 定律 for things that are merely habits or common occurrences. Reserve it for principles that carry the weight of scientific or mathematical proof.

To truly master 定律 (定律), you must see how it fits into the family of words related to rules and principles. Each has a specific nuance that changes the meaning of your sentence.

规律 (guīlǜ) vs. 定律 (dìnglǜ): 规律 is about patterns and rhythm. Example: "The pattern of the seasons" (季节变化的规律). It is descriptive. 定律 is about the fixed mechanics. Example: "The law of gravity" (万有引力定律). It is prescriptive and explanatory.
法则 (fǎzé) vs. 定律 (dìnglǜ): 法则 is often more abstract or philosophical than 定律. It is frequently used in phrases like "Survival of the fittest" (优胜劣汰的法则) or "The rules of nature" in a more poetic sense. 定律 is more technical and scientific.
原理 (yuánlǐ) vs. 定律 (dìnglǜ): 原理 translates to "principle" or "theory of operation." It explains *how* something works. 定律 states *what* the relationship is. For example, you might study the "principles of flight" (飞行原理) to understand how the "laws of physics" (物理定律) allow a plane to stay in the air.

大自然的生存法则是残酷的。
(The rules/laws of survival in nature are cruel.)

我们需要掌握市场运行的规律。
(We need to master the patterns of market operation.)

牛顿第一定律也叫惯性定律。
(Newton's First Law is also called the Law of Inertia.)

By choosing between these synonyms, you can express yourself with much greater precision. Using 定律 specifically signals that you are referring to something that is not just a trend, but a fundamental, unchanging truth of the system you are discussing. This nuance is key to achieving a high level of Chinese proficiency.

자주 하는 실수

Using 定律 for traffic rules. → 使用法律或规则。
Traffic rules are man-made and can change. 定律 is for natural, unchanging laws.
Pronouncing 'lǜ' as 'lù'. → Keep the 'ü' sound rounded.
The 'ü' sound is distinct in Chinese. 'Lù' means road/path; 'lǜ' means law/rule.
Using 定律 instead of 规律 for patterns. → Use 规律 (guīlǜ).
If you are describing a trend (like the stock market rising in winter), it's a 规律, not a 定律.
Using '个' as the only measure word. → Use '条' (tiáo).
While '个' is understood, '条' is the standard measure word for laws and long, thin things (including abstract ones).
Confusing 定律 with 定理 in math. → Use 定理 (dìnglǐ) for theorems.
Theorems are proven within a system (math); laws are observed in the physical world (physics).
