These three cost-effectiveness ratios are quite high. Both computer and automation rank in the top 20 with 2 1 1, among which automation can even rank around 10, and computers will not fall out of 30 at all. It can be said that if you like, the cost performance is too high. Underwater sound is the treasure of the town and school, which may not be highly valued by the society, but it is also a school, only four or six times.

Underwater acoustic specialty belongs to the discipline of ship engineering and is the trump card specialty of Harbin Institute of Technology. China ranks first and belongs to a minority major. Ye Cong, the chief designer of Endeavour with a manned dive of 10,000 meters, is a student majoring in ship engineering at Harbin Engineering University.

Whether it's computer, automation or underwater acoustics, if you are in a hurry for money, you must be a computer major. If you don't put money first, it depends on your personal interest.
