On the resistance of capillary hysteresis, the model of high powerpulsating heat pipe is improved and the flow and heat transfer are further studied.
在毛细滞后阻力方面，改进了所建立的高功率脉动热管的模型，进一步研究了脉动热管的流动和传热特性。

At present power converters of DC driving system make power supply outputs a high-frequency pulsating current, which is from zero to the armature current. This large ripple damages batteries.
In this paper, it is pointed out that the ripple factor will meet the test demands by choosing 12 pulsating wave controlled rectifying power supply as the test supply.
