In this paper the relation between the hole diameter and the pile thickness of the jet on the hole bottom for a jet penetrating or drilling process is theoretically examined.
本文在理论上探讨了射流在侵彻或钻孔过程中，孔径和射流在孔底的堆积厚度之间的关系。

Diamond film wafers with different thickness were prepared by high power DC arc plasma jet CVD method.
采用高功率直流电弧等离子体cvd工艺制备了不同厚度的无裂纹自支撑金刚石厚膜。

Especially they improved the thickness of curved way water tongue and the uniformity of current velocity which distribute in a cross section, promise the stability and the safety of the end jet flow.
