Research on propagation and climb height of surge triggered by landslide in reservoir;

Explicit Formula for Calculating Surges in Throttled Surge Tank Following Load Rejection;

Horizontal 2-D flow model with variable grid for simulating surges due to landslide in reservoirs;

The dynamic ocean surface containing swell is constructed on the basis of random ocean wave theory,and the Mapping Project Algorithm(MPA) is introduced to simulate polarimetric Synthetic Aperture Radar(SAR) images of ocean wave.

Whether the swell produced by the coffer dam falls can causes the harm to the periphery building and the environment,is always the problem people concerned.

By comparing two different directional distributions,it s shown that the directional distribution recommeded in the nowaday specifications in China is characteristic of wind wave and swell with short propagation distance and in good agreement with Mitsuyasu direction distribution.

The defects of the traditional methods of internal limiting surge current are pointed out.

The limitations of the traditional methods of limiting surge current, such as bigger energy consumption, second surge current and function failure are pointed out.

Using the techniques of DAC control and soft-start voltage sense,the rush current and overshoot of the output voltage during start-up are eliminated effectively,allowing for a smooth output voltage ramp from zero to regulation.

A novel CMOS-compatible soft-start circuit for DC-DC switching regulator is presented,by using the technique of current limit and digital soft-start,which eliminates the rush current and the overshoot of the output voltage during start-up effectively.
