velocity spread meaning in English
速度分布
Examples
- Discuss the important elements that affect beam velocity ratio and velocity spread
论述影响电子注速度比、电子注速度零散的主要因素。 - Due to applying double beams , the velocity spread is lower because of smaller influence of space charge compared with single beam mig . in the interaction region this beam is easy to start oscillation and reject mode competition effectively
与单注磁控注入枪相比,双注枪可以提供速度零散小、高束流的电子注,在互作用区更容易起振,且能更好的抑制模式竞争。 - Based on the self - consistent nonlinear theory of complex cavity gyrotron with gradual transition , a simulation code of self - consistent nonlinear beam - wave interaction has been made , in which the multiple modes interaction with an electron beam and the mode coupling are taken into account . the interaction between the electron beam and hsn - h521 rf field for third - harmonic gyrotron is simulated . the influences of the thickness and the velocity spread and the velocity ratio of the electron beam and the fluctuation of the magnetic field and the technologic errors of complex cavity on the multi - modes interaction with an electron beam are analyzed
二、在渐变复合腔回旋管多模自洽非线性理论的基础上，编制了高次谐波渐变复合腔回旋管多模注?波互作用自洽非线性模拟软件，并对8mm波段三次谐波渐变结构复合腔回旋管的注? ?波互作用进行了大量的自洽非线性数值模拟计算与研究，进而分析了电子注的厚度、速度零散、速度比值、磁场波动、腔体尺寸的加工误差等等多种因素对互作用效率的影响。
