space-charge effect meaning in Chinese

空间电荷效应

The input electrical power at the given voltage is increased due to the larger emitting surface of the radial structure and the space - charge effects are also relatively small
用一维模型对折叠式谐振腔径向速调管振荡器进行了理论研究，分析了结构器件参数对束波相互作用的影响。
The main results are as follows : 1 . the propagation of an ultrashort intense pulse laser beam in low - density plasmas is investigated analytically . relativitistic pondermotive force and space - charge effects are included , and an equation describing the evolution of the laser spot size is derived
