| Abstract: | The different pressure changing courses in hydraulic machinery were simulated through experiments, after each course, the pressure-time data was recorded, then the carps and grass carps injured were checked and anatomized. In present studies, it is demonstrated that fishes are severely injured after pressure changing courses during subatmospheric condition, and the maximum derivative of pressure with respect to time safe for fishes is concluded, which should be adopted in the design of new environmentally friendly hydraulic machinery. |
