1·The content includes: Chosen value of air gap and its influence upon the short circuit ratio;

内容包括：气隙取值及其对发电机短路比的影响；

2·EDM in gas can make less electrode wear, but its high short circuit ratio will lead to unstable process and thus low material removal rate.

气中电火花加工时电极相对损耗很小，但由于短路率过高导致加工不稳定、材料去除率不高，还会产生烧焦气味。

3·Because the traditional short circuit ratio(SCR) is not able to reflect the interaction of HVDCs into account, it is urgent to propose a new definition of SCR for MIDC systems.

由于传统短路比不能考虑直流间的相互作用而亟待提出适用于多馈入交直流系统的短路比定义。

4·It was proved that high Speed Assist Submersed Gas-jetting EDM Milling is an effective solution to solve high short circuit ratio problem of EDM in gas, and reveals good machining performance.

本文的研究证明，高速平动液中喷气电火花铣削加工性能良好，是一种有效解决气中电火花加工短路率过高问题的方法。

5·The results show that turbulence inhibitor has the functions of preventing sputter of liquid steel during casting, avoiding the reoxidation of steel, and decreasing the ratio of short circuit.

结果表明，湍流控制器可起到减小钢水喷溅、防止二次氧化和改善流体运动路线的作用，并减少短路流的发生。
