The mathematical model of plasma arc jet velocity at the exit of orifice logically combines the structural sizes of orifice with the plasma gas flow rate, the temperature of plasma arc at the exit of orifice, intensity of ionization and the force of arc pinch effect, by which the velocity of plasma arc jet can be estimated.

当喷嘴结构参数，离子气流量一定时，等离子弧在喷嘴出口处的温度和电离度的增加能使射流的喷嘴出口速度显著增加，而电磁压缩力使射流的喷嘴出口速度增加得较少。

Switching arc can be thought as a column because of its self-magnetic field pinch effect. Arc column is deformed by magnetic force that produced by circuit current flow. If the arc image was acquired from a orthongonal direction to arc column deformation force.

在分析低压电器开关电弧的低温等离子体特性、弧柱磁压缩效应的基础上，提出了基于电弧图象采集和非均匀有理B样条曲面拟合相结合的开关电弧可视化仿真模型。

The result shows that, when a free droplet transfer mode is applied in high-speed welding , the workpiece is heated by the arc throughout the process and thus the molten pool can not solidify in time.As a result, the molten pool is very long, which gives way to the instability of bead formareron and pinch effect of the liquid metal,so that it finally leads to the humping phenomenon. Based on the analysis and experimental result, the short-circuiting transfer mode is suggested to improve the bead formation in high-speed welding .

理论分析和试验结果均表明，采用自由过渡的熔滴过渡形式进行焊接，工件始终处于焊接电弧的加热下，在高速焊接时，熔池不能及时冷却，熔池明显拉长，由扰动引起的振动波长大，当熔池的拉长达到一定程度时，会发生液体金属的失稳和颈缩的现象，造成驼峰焊道。

The main conclusions of this work are listed below:The cyclic loops of these two types of connections are nearly rectangular, and there is no pinch or just a little effect was found. These loops indicate the good dissipation of energy.The axial-compression ratios affect little the cyclic loops in this test.

得出的主要结论如下：梁柱缀板连接节点和梁柱穿芯螺栓—加劲端板连接节点的位移滞回曲线与转角滞回曲线图形饱满，没有或略有捏拢现象，耗能能力强。

Saddle shaped AMF can produce a radial expanding force, which has more effective effect on resisting the pinch effect of self-generated azimuthal magnetic field of arc current. This effect of saddle shaped AMF can keep vacuum arc in diffuse mode under much higher current. So the limiting current interruption capacity of vacuum interrupter can be enhanced.

为了进一步提高纵向磁场对真空电弧的控制作用，本文提出在真空灭弧室的触头间引入从触头中心向边缘逐渐增强的非均匀纵向磁场，马鞍形纵向磁场会对真空电弧产生一个径向扩张力，而纵向磁场分布的合理设计可以使这一扩张力进一步抑制真空电弧自生环向磁场对电弧的箍缩作用，从而使真空电弧在更大的电流时仍能保持在扩散态，使真空灭弧室的极限电流开断能力得以提高。

The example further proves that the advocated semi-active control strategy could prompt the dynamic damping performance of the MR damper, behaving as a type-like Bouc-Wen model with the strength deterioration, the stiffness degradation and the pinch effect.
