图象发射机栅调管中,帘栅引线电感L_g2成为输出、输入电路之间的耦合元件,它形成高频反馈,如图1所示。图中:C_ag1——屏、栅间电容;C_ag2——屏、帘栅间电容;C_g1g2——栅、帘栅间电容;L_g2——帘栅引线电感; In the image transmitter grid tube, the screen lead inductance L_g2 becomes a coupling element between the output and the input circuit, which forms a high-frequency feedback, as shown in FIG. 1. C_ag1-- screen, the capacitance between the grid; C_ag2-- screen, the capacitance between the screens; C_g1g2-- capacitance between the grid, the grid; L_g2-- screen lead inductance;
