摘　　要：介绍了卡茨曼给出的计算电子管功放级的一种新算法,指出卡氏法的局限性,提出有用的改进意见,建立了利用通用曲线进行计算的方法。按此方法可对欠压、临界、弱过压状态的电子管功率放大器进行计算,精度与图解法(十三点法)相近。新法物理意义明确,计算简便,适于现场使用。A new calculation method for Katzman's calculation on the vacuum tube power (magnification) step is presented. The limitation of Katzman's method is pointed out, and some useful improved ideas are proposed. A calculation method by the use of a general curve is established. The vacuum tube power amplifier can be calculated at under-voltage, critical voltage and slight overvoltage conditions. Its precision is about the same as that of the graphical method (13 points method). The physical meaning of the new method is clear; the calculation is simple and convenient, and is suitable for use at the worksite.
