“control grid”的概念、定义、习题解题方法及翻译-物理辞典

单词	control grid
释义	control grid A wire-mesh electrode placed between the cathode and anode in a thermionic valve or a cathode-ray tube to control the flow of electrons from one to the other. A fluctuating potential signal fed to the control grid produces at the anode a current signal with similar but amplified fluctuations. It thus forms the basis of the electronic valve amplifier. In a cathode-ray tube the grid controls the intensity of the electron beam and hence the brightness of the image on the screen
