Sun Jinliang

Sun Jinliang is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Sun Jinliang rather than just read about it. In short: Sun Jinliang (simplified Chinese: 孙晋良; traditional Chinese: 孫晉良; pinyin: Sūn Jìnliáng, born January 1946) is an academician of the Chinese Academy of Engineering (CAE) and professor of material science and engineering in Shanghai University.

Key takeaways

Sun Jinliang belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Sun Jinliang to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Sun Jinliang from memory before moving on to harder problems.

Reference excerpt

Worked examples

Example 1 — a first encounter with Sun Jinliang

Start with the simplest possible case. Write down what Sun Jinliang claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sun Jinliang before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sun Jinliang ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sun Jinliang

In research: Sun Jinliang appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Sun Jinliang in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Sun Jinliang is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1946 births, 20th-century Chinese engineers, Academic staff of Shanghai University, so understanding it makes those chapters shorter.
In everyday life: Look for Sun Jinliang outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Sun Jinliang in simple terms?

Why does Sun Jinliang matter?

Because it connects several engineering ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Sun Jinliang?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
