In this paper,the anti-scaling effect of EWP which used square-wave pulse current have been studied,the data show that the anti-scaling rate is 100% when the voltage is 2V.

In order to explore the electromagnetic pulse s effect on the electronic device,the experiments on LM324N and CD4069UB with the square-wave pulse of different width are done,in which it is found that the device circuit s damageis related to the magnitude of pulse energy to a great extent,and there is a phase from adiabatic course to therma.

Some integrated circuits were injected by rectangular pulse and ESD pulse for comparison of the damage effects caused by the two types of pulses.

The similarities and differences of damage effects of integrated circuits were studied by the test that two chips were injected by ESD and rectangular pulse respectively.

Effects of Rectangle Wave Pulse Current on Solidification Structure of Al-Cu Alloy;

The occurrence cycle of eyehole in laser deep penetration welding is analyzed in theory, and the method of removing the effect of plaser during laser welding by adoption of squarewave pulse laser and assistant gas is put forward.

The susceptibility of AISI 304L austenitic stainless steel to intergranular attack mainly caused by the Cr-depletion in grain boundaries was detected by the square-wave potentiostatic pulse technique.
