Zhang Liqun

Zhang Liqun 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 Zhang Liqun rather than just read about it. In short: Zhang Liqun (Chinese: 张立群) is the president of Xi'an Jiaotong University since March 2024. He was former president of the South China University of Technology from 2022 to 2024.

Key takeaways

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

Reference excerpt

Zhang Liqun (Chinese: 张立群) is the president of Xi'an Jiaotong University since March 2024. He was former president of the South China University of Technology from 2022 to 2024.

Education Zhang obtained his BS (1990), MS (1992), and PhD (1995) degrees from the Beijing University of Chemical Technology. He was a visiting scholar at the University of Akron in Ohio from 1990 to 2000 and a postdoctoral researcher at Case Western Reserve University in Ohio from 2000 to 2001.

Career Zhang has been a professor at the College of Materials Science and Engineering (CMSE) at the Beijing University of Chemical Technology since 1995, and College Dean since 2016. He began to serve as president of the South China University of Technology in 2021. During his tenure, the university has established partnerships with BASF, with the Nanyang Technological University of Singapore, and with Mahidol University. Zhang is a member of the editorial board of the scientific journal Nano-Structures and Nano-Objects. His most cited work concerns the application of a Halloysite clay nanotube to achieve a delayed release of antioxidants in a rubber compound, thus achieving an enhancement to anti-ageing properties.

Worked examples

Example 1 — a first encounter with Zhang Liqun

Start with the simplest possible case. Write down what Zhang Liqun 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 Zhang Liqun 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 Zhang Liqun 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 Zhang Liqun

In research: Zhang Liqun 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 Zhang Liqun 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: Zhang Liqun is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1960s births, Academic staff of Xi'an Jiaotong University, Academic staff of the South China University of Technology, so understanding it makes those chapters shorter.
In everyday life: Look for Zhang Liqun 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.
