Liu Diansheng

Liu Diansheng is a astronomy 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 Liu Diansheng rather than just read about it. In short: Liu Diansheng (Chinese: 刘滇生; born May 1953) is a Chinese chemist, academic, and politician. He is a member of the Jiusan Society and previously served as a member of the Standing Committee of its Central Committee.

Key takeaways

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

Reference excerpt

Liu Diansheng (Chinese: 刘滇生; born May 1953) is a Chinese chemist, academic, and politician. He is a member of the Jiusan Society and previously served as a member of the Standing Committee of its Central Committee. He also served as vice chairman of the Shanxi Provincial Committee of the Chinese People's Political Consultative Conference and as president of the Shanxi Socialist Institute.

Biography Liu was born in May 1953 in Xia County, Shanxi. He began working in November 1971 as a worker at a chemical plant in Changzhi. In 1973, he was admitted to the Department of Chemistry at Shanxi University, where he studied analytical chemistry and graduated in 1976. He later worked as a technician in a biochemical pharmaceutical workshop in Yuncheng before returning to Shanxi University for postgraduate studies in physical chemistry, earning a master's degree in 1981. Following graduation, Liu remained at Shanxi University as a faculty member, serving successively as an assistant lecturer and lecturer. In 1989, he went to the United Kingdom, where he pursued doctoral studies in organic chemistry at the University of Sussex and subsequently conducted postdoctoral research there. In 1995, he was a visiting scholar at the Chinese University of Hong Kong. After returning to China, Liu held a number of academic leadership positions at Shanxi University, including head of the Department of Chemistry, assistant to the president, and vice president from 1998 to 2007. He was promoted to professor and doctoral supervisor during his academic career. Liu entered public service through the Jiusan Society, becoming chairman of its Shanxi provincial committee in 2007 and a member of the Standing Committee of its Central Committee. He served as vice chairman of the Shanxi Provincial Committee of the Chinese People's Political Consultative Conference from 2008 to 2017. From 2014 to 2018, he concurrently served as president of the Shanxi Socialist Institute.

Worked examples

Example 1 — a first encounter with Liu Diansheng

Start with the simplest possible case. Write down what Liu Diansheng claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, 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 Liu Diansheng 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 Liu Diansheng 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 Liu Diansheng

In research: Liu Diansheng appears in astronomy 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 Liu Diansheng 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: Liu Diansheng is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1953 births, Alumni of the University of Sussex, Chinese chemists, so understanding it makes those chapters shorter.
In everyday life: Look for Liu Diansheng 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.
