secondary emission 【物理學】次級發射。

secondary evidence

The dust charging associated with the electron beams including the secondary emission of dust can dominate the dust surface potential in the close cathode region . in this case , dust of the same size can levitate at two different positions in the cathode 另外還發現:在考慮極板有強電子束發射和塵埃粒子本身的二次電子發射時,同一大小的塵埃粒子能夠懸浮在鞘層中兩個不同的位置。

The empirical formula in the process of the secondary emission is analyzed ; the stabilization condition of vacuum surface flashover is deduced . the physics image of the vacuum surface flashover is described with the seea theory 本文分析了二次電子發射過程的經驗公式,推導了真空表面閃絡的穩定條件,以seea理論的觀點描述了真空表面閃絡發生的物理圖象。

There may be secondary emission effects that depend on theplate material 而且還有屏極材料不同導致的二次發射現象。
