He Jing (engineer)

He Jing (engineer) 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 He Jing (engineer) rather than just read about it. In short: He Jing (Chinese: 何璟; December 1934 – 22 November 2019) was a Chinese hydraulic engineer and politician. She served as chief engineer and vice minister of the Ministry of Water Resources of the People's Republic of China, and was the chief designer of the Ankang Dam and the Shiquan Dam.

Key takeaways

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

Reference excerpt

He Jing (Chinese: 何璟; December 1934 – 22 November 2019) was a Chinese hydraulic engineer and politician. She served as chief engineer and vice minister of the Ministry of Water Resources of the People's Republic of China, and was the chief designer of the Ankang Dam and the Shiquan Dam.

Biography He Jing was born in December 1934 in Fuzhou, Fujian, Republic of China. She graduated from East China Institute of Hydrology (now Hohai University) in 1956, and joined the Chinese Communist Party the same year. In 1956, she became an engineer at the Beijing Survey and Design Institute of the Ministry of Electric Power, and participated in the design of the Liujiaxia Dam. After 1976, she served as chief designer of the Ankang Dam in Shaanxi. She also designed the Shiquan Dam (石泉电站), which won the State Science and Technology Progress Award (Second Class). She was appointed chief engineer of the Ministry of Water Resources of the People's Republic of China in 1988, and vice minister in 1993. From 1997, she served as an advisor to the State Power Corporation of China. She became an advisor to China Datang Corporation in 2003.

Personal life He Jing married Lu Youmei, her classmate at East China Institute of Hydrology. Lu, also a hydraulic engineer, is an academician of the Chinese Academy of Engineering. She died on 22 November 2019 in Beijing, aged 84.

Worked examples

Example 1 — a first encounter with He Jing (engineer)

Start with the simplest possible case. Write down what He Jing (engineer) 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 He Jing (engineer) 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 He Jing (engineer) 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 He Jing (engineer)

In research: He Jing (engineer) 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 He Jing (engineer) 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: He Jing (engineer) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1934 births, 2019 deaths, 20th-century Chinese women politicians, so understanding it makes those chapters shorter.
In everyday life: Look for He Jing (engineer) 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.
