What is a traditional industry?

Traditional industries are all kinds of industries and projects established after the steam engine revolution in18th century, the electrification revolution in19th century and the networking revolution of atomic energy and computer information in 20th century.

For example: textile industry; Mining industry (coal, fluorite, gold, silver, copper, iron, tin, aluminum, lead, nickel, mercury, platinum, etc. ); Metallurgical industry (steelmaking, iron, nickel; Tin, lead, copper, aluminum, silver, gold, mercury, potassium, sodium, calcium, magnesium, zinc, etc. ); Machinery manufacturing (generators, motors, transformers, transformers, motorcycles, automobiles, trains, tractors, airplanes, shipbuilding,); Chemical industry (coking, benzene production, xylene, coal tar, diesel oil, gasoline: hydrochloric acid, nitric acid, sulfuric acid, sodium hydroxide, sodium carbonate, sodium bicarbonate, etc. ); Plastics industry (PVC, polystyrene, polysulfone, ABS, polycarbonate engineering plastics, hydrogen production H, oxygen O, nitrogen N, helium and pharmaceutical industry, aspirin, metoclopramide, Chinese and western medicines). Analog TV made of semiconductor (transistor) integrated circuits developed in the 20th century is called traditional industry.

The characteristics of traditional industries and products are "big and stupid". Including the most fashionable products, so are computers. For example, 1946, the first computer made of electron tubes weighed 30 tons; It is several stories high, and the DIS- 130 computer and its supporting products produced in the early 1980s have several hundred kilograms, which is equivalent to several refrigerators. At the end of 1980s, the same computer was made, which can be reduced to a silicon chip the size of a fingernail, and the operation speed is much faster than it. 2 1 century entered the period of high-tech development, and the same computer could be reduced to a big (small) rice grain.
