Technical Terms on Hydraulic Engineering (2)

With the rapid development of world science and technology, we need to read and translate a great quantity of foreign scientific and technical literature to learn and use foreign advanced science and technology. Hydraulic Engineering is one of such fields and it is also an extensive subject with special characteristics. Like other subjects, it has a large number of technical terms and it will be helpful if you master a lot of specialized vocabulary of this area. I just list some technical terms learnt from translation and divide them into following categories. 1.
