Problems solved by technology

At that time, teaching technology was backward, there were no tape recorders, and there were no copiers...Students relied on taking notes in class
"Concrete" is the most commonly used word in construction engineering, but with too many strokes, it is laborious and time-consuming to write! So the quick-thinking Cai Fangyin boldly used the word "artificial stone" instead of "concrete".

Description

technical field [0001] The invention relates to the fields of commercial concrete technology, electronic technology and the like, specifically, it is a flow pressure conversion circuit applied to a commercial concrete production management system. Background technique [0002] Commercial concrete is commercial concrete, which was created by Professor Cai Fangyin, a famous structural scientist, in 1953. On June 7, 1985, the Chinese Language Reform Commission officially approved the synonym of "concrete" and "concrete". [0003] Concrete (tóng) is the scientific name of concrete. [0004] The creator of the word "concrete" is Professor Cai Fangyin, a famous structural scientist. The creation time is 1953, so far 60 years. At that time, teaching technology was backward, there were no tape recorders, and there were no photocopiers... Students took notes in class. "Concrete" is the most commonly used word in construction engineering, but with too many strokes, it is laborious ...
