Line 2 (Nanjing Metro)

Line 2 (Nanjing Metro) is a science 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 Line 2 (Nanjing Metro) rather than just read about it. In short: Line 2 of the Nanjing Metro (Chinese: 南京地铁2号线; pinyin: Nánjīng Dìtiě ÈrHào Xiàn) is a subway line that runs mainly in an east-west direction on the Nanjing Metro network, running from Jingtianlu to Youfangqiao; it entered operation on May 28, 2010. It covers a length of 37.95 km (23.58 mi) with 26 stations.

Key takeaways

Line 2 (Nanjing Metro) belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Line 2 (Nanjing Metro) to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Line 2 (Nanjing Metro) from memory before moving on to harder problems.

Reference excerpt

Line 2 of the Nanjing Metro (Chinese: 南京地铁2号线; pinyin: Nánjīng Dìtiě ÈrHào Xiàn) is a subway line that runs mainly in an east-west direction on the Nanjing Metro network, running from Jingtianlu to Youfangqiao; it entered operation on May 28, 2010. It covers a length of 37.95 km (23.58 mi) with 26 stations. Of the 26 stations, 17 stations are underground, 2 stations are on the surface, and the other 7 station are either above ground or elevated stations. The section between Maqun and Jingtianlu was originally planned as an east extension of Line 2, but it entered operation, together with the main line, on the same day.

Worked examples

Example 1 — a first encounter with Line 2 (Nanjing Metro)

Start with the simplest possible case. Write down what Line 2 (Nanjing Metro) claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Line 2 (Nanjing Metro) 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 Line 2 (Nanjing Metro) 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 Line 2 (Nanjing Metro)

In research: Line 2 (Nanjing Metro) appears in science 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 Line 2 (Nanjing Metro) 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: Line 2 (Nanjing Metro) is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2010 in Nanjing, Nanjing Metro lines, Railway lines opened in 2010, so understanding it makes those chapters shorter.
In everyday life: Look for Line 2 (Nanjing Metro) 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.
