special discharge

By studying the relationship among discharge current, discharge voltage and air pressure, we find that the dc HCD operates in a special glow mode, which is an intergrade between normal and abnormal glow discharge.

通过对直流空心阴极放电过程的研究，证明其是一种介于正常辉光放电与反常辉光放电之间的一种特殊的辉光放电形式。

WEDM ( Wire-Cut Electrical Discharge Machining) is a kind of special machining way which is usually used for mold fabricating, formed cutter tooling and complex and precision shapes, etc.

电火花线切割加工（Wire-Cut Electrical Discharge Machining，简称WEDM）属特种加工，通常用来切割轮廓曲线比较复杂的零件，如：模具、成形刀具等，对加工精度有较高的要求。

By adding special conductivity-improving materials and increasing real reaction surface. the impedance of MH/ Ni battery was decreased to make it suitable for electric bicycles on which the batteries were due to continuously discharge on high current.

采用在电极中加入导电性好的导电剂以及增大电极的真实面积的方法，使电池内阻降低，制成适合电动自行车用可连续大电流放电的MH/Ni电池。
