To improve the stability of Arcjet discharge plasma in low current and high voltage mode, research on the demand of output characteristics of Arcjet Power Conditioning Unit was conducted. In this paper, based on PWM invertors and current mode control, using MOSFET as the main power device, an Arcjet Power Conditioning Unit was developed. Through adding a closed loop feedback circuit of output voltage, it can make the output characteristics of PCU be positive resistance to ensure the stability of Arcjet discharge plasma. The experiment indicates that this PCU can make Arcjet engine work at high voltage mode (100 V, 10 A) and ensure the stability of arcjet discharge plasma. Finally, it provides the experimental data of Arcjet when working.

Particles shorter or narrower than 0.04m seem to not be drawn at all... UNLESS at some point in the particles life it is both wider and taller than 0.04m, your milage may vary.

粒子效果，当短窄于0.04m，这是不充许的，除非粒子效果中的一些点包括宽和高于0.04m，你的milage可能会变大。

The rules of fluid rate with different technical parameters: the increase of electromagnetic force causes the increases of the fluid rates at S/L interface and free surface, the decrease of skin depth, the increase of electric current density which will make the fluid at free surface flowing faster, while it doesnt affect the fluid rate at S/L interface. When the height of melt increases, the both of fluid rates will increase too. The increase of the width-thickness ratio augments the fluid rates along the wider edges at S/L interface evidently, while the rates along the narrow edges will have little change, and the rate at free surface has little change too. The increase of overheat degree minishes the range of mush zone, while the fluid rates at S/L interface and free surface will increase evidently.

流速的大小随各种不同工艺因素的变化呈现出一定的变化规律：随电磁力的增大，固液界面以及自由表面处的流速都会增大；集肤层渗入深度变薄，电流密度增大，会导致自由表面上流动的加强，但对固液界面处的流动速度影响不大；熔区高度的增加，也会使固液界面及自由表面处的流动增强；宽厚比增大时，固液界面上沿宽面方向的流动显著增强，但窄面方向流速变化不大，同时自由表面上流速变化也较小；过热度及温度梯度的增大，使糊状区减小，导致固液界面及自由表面处的流速显著增大。
