在电子管的静态参数中,二栅电流也是一个比较重要的参量。它的大小直接决定着二栅所承受的功率。因此,在电子管的结构设计和参数调整时,计算二栅电流的大小具有一定的实际意义。对发射四极管来说,为了减小二栅电流,一般都采用一栅、二栅严格地对栅。这种系统的二栅与阳极之间的电流分配,作为直接可采用的计算公式,在一般文献中介绍得不多。因 In the static parameters of the tube, the second gate current is also a more important parameter. Its size directly determines the power of the second gate. Therefore, in the structure of the tube design and parameter adjustment, the calculation of the size of the two gate current has some practical significance. For the transmitting diode, in order to reduce the second gate current, a gate is generally used, and the second gate is strictly on the gate. The current distribution between the double gate and the anode of such a system, as a straightforward formula, is not much described in the general literature. because
