The principles of obtaining optimum design for R-C coupled pentode ampli- fiers are obatined. It was shown that for small input signals, operation is limit- ed in so small a portion of the characteristic that much smaller than usual grid bias may be used to obtain higher trangconductance, and consequently higher gain; whereas for large input signals,non-linearity of the characteristics limits the maximum output obtainable. Therefore, design should be different for small and for large input signals. After...

The principles of obtaining optimum design for R-C coupled pentode ampli- fiers are obatined. It was shown that for small input signals, operation is limit- ed in so small a portion of the characteristic that much smaller than usual grid bias may be used to obtain higher trangconductance, and consequently higher gain; whereas for large input signals,non-linearity of the characteristics limits the maximum output obtainable. Therefore, design should be different for small and for large input signals. After the load resistance was obtained from other considerations, it was shown how the required optimum voltages on the screen grid and for grid bias can be obtained from the standard characteristic curves of pentodes given in radio tube handbooks. Concrete examples are used in elucidat- ing these principles.

根据几个合理的假定,我们可以用分析方法求得电子注功导管(或五极管)的调幅特性。证明要得到没有畸变的调幅,必须使阳极电压、屏栅极电压、栅偏压和栅极激励用上压同时加以调制。所要求的调制方式都是很近于同比例的。实验上,这样的四重调制可以用很简单的线路和不需要任何特殊设备得到。本文也讨论了用这种调制方式的其他优点。

直接连于架空线路的电机迄今尚无可靠的防雷方式,因之我国这类电机的雷害事故非常严重。本文介绍了一种实际上可以完全保护这类电机的防雷方式(参考图1),即在11仟伏级时进线段用100公尺铁丝网包围起来,网首装管型避雷器PT_1,母线上装电容器C,而在3.3及6.6仟伏级时只要再加50公尺电缆段即可。理论和实验证明,这时6.6及11仟伏级的电机的耐雷指标可达1180年,3.3仟伏级的电机的耐雷指标可达37年。而且这种防雷方式所需投资比其它防雷方式都少。建议电力部审查采用。

Finally, several regulation systems are recommended for exciters with Smaller and larger time constants.
