Lin Junde

Lin Junde 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 Lin Junde rather than just read about it. In short: Lin Junde (Chinese: 林俊德; pinyin: Lín Jùndé; Pe̍h-ōe-jī: Lîm Chùn-tek; 13 March 1938 – 31 May 2012) was a Chinese explosion mechanics scientist and researcher at Xinjiang Malan Nuclear Test Base. He had spent 52 years working in the Gobi Desert in northwest China, participating in the nuclear tests there.

Key takeaways

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

Reference excerpt

Lin Junde (Chinese: 林俊德; pinyin: Lín Jùndé; Pe̍h-ōe-jī: Lîm Chùn-tek; 13 March 1938 – 31 May 2012) was a Chinese explosion mechanics scientist and researcher at Xinjiang Malan Nuclear Test Base. He had spent 52 years working in the Gobi Desert in northwest China, participating in the nuclear tests there. He held the rank of major general (shao jiang) in the People's Liberation Army (PLA). He was a member of the Chinese Academy of Engineering.

Biography Lin was born in Jiefu Township of Yongchun County, Quanzhou, China on March 13, 1938. After graduating from Zhejiang University in 1960, he was assigned to study at PLA Military Institute of Engineering in Harbin, northeast China's Heilongjiang province. In May 1963 he was transferred to the PLA General Equipment Department, where he headed the development of pressure recorder for measuring nuclear explosion shock wave. From the explosion of China's first atomic bomb in 1964 to the last underground nuclear test in 1996, he participated in all 45 nuclear tests in China. In 1993 he was promoted to the rank of major general (shao jiang). In 2001 he was accepted as an academician of the Chinese Academy of Engineering. On May 31, 2012, he died of cholangiocarcinoma at the Tangdu Hospital, Xi'an, Shaanxi. Before he died, he said: "I've only done one thing in my life, nuclear test. I'm very satisfied." In February 2013, he was honored as one of the "Ten People Who Moved China".

Personal life In 1967 Lin married Huang Jianqin (Chinese: 黄建琴), who was his colleague at Xinjiang Malan Nuclear Test Base.

Worked examples

Example 1 — a first encounter with Lin Junde

Start with the simplest possible case. Write down what Lin Junde 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 Lin Junde 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 Lin Junde 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 Lin Junde

In research: Lin Junde 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 Lin Junde 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: Lin Junde is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1938 births, 2012 deaths, Explosives engineers, so understanding it makes those chapters shorter.
In everyday life: Look for Lin Junde 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.
