火花间隙

The arc is usually started by HF sparks which ionise the gap between the electrode and the workpiece.

电弧通常由高频火花电离电极和工件的间隙产生。

The HF sparks will cause the electrode - workpiece gap to break down or ionise.

高频火花将造成电极/工件间隙破坏或电离。

脉冲电磁波的传输特性在高频条件下对火花放电的影响很大，本文运用传输线理论研究电火花加工极间间隙内脉冲电压及电流波的传输行为，为电源和传输线设计提供依据。

爆震是在燃烧室内当火花跳过火花塞电极间隙以后发生的一种二次爆燃。

However, because of the natural characteristics of the micro and small hole EDM, such as weak discharge energy, high pulse power supply frequency, unstable spark discharge states and small discharge gap, etc., there are still some key technical difficulties in its machining process need to be solved: the difficulties in real-time discharge states detection, in accurate control of machining process, in prediction of discharge states, in improvement of machining system precision and in on-line preparation of micro electrode, etc.

但是由于微细及小孔电火花加工自身具有的放电能量极微、脉冲电源频率高、难以获得稳定的火花放电状态以及放电间隙极小等固有特性，决定了其加工过程仍然存在放电状态实时检测方法单一、加工过程难于准确控制、放电状态难于预测、加工系统精度提高困难和微小电极在线制备困难等关键性技术难点，亟待突破和解决。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
