With the rapid progress of the electronic art, there has been a steadily increasing demand for still wider-bandwidth amplifiers. The recent introduction of distributed amplification concept has provided a new technique and powerful means for designing amplifiers with top cutoff frequencies far in excess of those previously obtainable with,ordinary amplifier circuits. A distributed amplifier of the low-pass type can easily be constructed to have a uniform frequency response from audio frequencies to frequencies as high as several hundred me using conventional vacuum tubes. Unlike conventional circuits, distributed amplifiers have an attainable gain-bandwidth product which is not limited by shunt capacitance associated with the vacuum tubes and circuit wiring; the high-frequency limit being determined entirely by high-frequency effects within the tube proper.The purpose of this paper is to describe the basic principle of distributed amplification and to show how such an amplifier employing various types of transmission lines may be designed. Practical methods hi design and design details are given for a three-stage distributed amplifier, using fourteen 6AK5 pentodes with a frequency response of 0.1 mo to 140 mo and a gain of 33±1 db.Both the negative mutual-inductance m-derived and constant K artificial delay lines hare been used. The former offers the advantage of a more linear phase characteristic and a more uniform response both in amplitude and delay time.The experimental results corroborate the predictions based on the first-order theory described in this paper.

分布式放大是最近宽频带放大的最大成就,过去多年来电子学所应用的各种宽频带放大方法,其高频部分因受电子管电容和线路的分布电容所限制,不能获得理想的结果,而利用分布式放大的理论,所制成的宽频带放大器,远较一般普通的宽频带放大器,有更为宽阔的频带;从它的设计和构造上来看,也较负反馈的宽频带放大器为简单。制造一架自数千周至数百兆周的分布式放大器,在技术上并没有很大困难。本文拟对分布式放大的原理作扼要的分析;并提出了采用各类型仿真线所构成的分布式放大器的设计方法,并利用该设计方法,试作了一只三级十四管的分布式放大器,其增益为33±<1分贝,频宽自100千周至140兆周。由实验结果证明,采用m导出式低通滤波器所构成的仿真线的分布式放大器,实较用常K式者,具有更佳的相移特性和频率特性,这与理论上的分析是一致的。

The solution of the equations of higher degree, i. e. the factoring of multinomial, are frequently needed during the analysis and calculation of the amplifier circuits, for example, when concerning the frequency response, stability judgement arid phase compensation, etc. To solve the equation of higher degree is relatively difficult. The conventional way to do it is the graphic method. In this paper, the approximate solution method of the equation of higher dgeree and the estimation of the error are proposed. This method can be applied to the solution of the aformeritioned tasks by analytic method. It is simple, easy to use and rather accurate,suitable for use in teaching and ordinary circuit design. As a practical example a frequency response and stability judgement of an amplifier with negative feedback are chosen to show the use of this method.

在放大器电路的许多分析和计算中,例如:频率响应、稳定性判别和相位补偿等等,都会到解高次方程,即多项式因式分解的问题。但解高次方程比较困难,过去主要采用图解的方法。本文提出利用电子计算器求解高次方程的近似根及其误差,因而可以直接应用解析方法解决上述各种问题。这种方法简单易行,误差小,在教学和一般的电路设计中便于学习和应用。本文还选择了频率应和负反馈放大器稳定性判别中的一些实际问题,作为这种方法应用的实例。

This paper analyzes the static and dynamic characteristics in Kaplan turbines which involve the following factors: the additional components of the turbine dynamic moment, the water flowing lag effect when the water flows from the guide vane to runner, and the water inertia time constant of water column in the penstock ( Tw1 ) , which should include a correct factor H due to the three dimensional flow in the spiral case. The concept of effective mean instllation head is introduced, considering that the transient pressure distributed along the periphery of the guide vane is nonuniform. In addition, as the hydraulic turbine regulating element is set in the middle position of the water way, the guide vane should act as the interface of the water hammer. By way of a frequency response calculation taking into account the factors mentioned above, a numerical example to check the stability of a hydraulic turbine control system is given. Especially for the system with pure lag, that the system is stable can be insured if the actual lag time τ0 is less than the critical lag time τoc obtained theoretically. The control strategy for the follow-up device of a duplex controller during load variation is further discussed. Finally, some conclusions and suggestions are given.

本文分析了转桨式水轮机的静特性和动特性特点,计入动态力矩的附加分量、导叶到转轮的流动滞后和管道惯性时间常数(含有流动修正系数x)。因为导水机构位于压力流道的中部且作为水锤界面,故又引入了装置水头升高平均值的概念。还给出了数字例,用频率法验证系统的稳定性。对具有纯滞后的系统,计算所得系统的实际滞后时间τ若小于理论分析得出的临界滞后时间τ_(0c),则系统的稳定是保证的。讨论了具有协联装置的双调整调速器在增减负荷时应采取的调节策略问题。最后,提出有待研究的几点建议和某些结论。
