Summary The efficiency of thermistor mount is defined as the ratio of power absorbed by thermistor to the total input power in mount.Because of losses caused by waveguide wall,casing of thermistor and poor contact etc,the efficiency is always less than one hundred percent. Determination of efficiency of thermistor mounts prossessed practical importance for the error analysis and calibration of powermeter.It is also important for the research or improvement of thermistor mounts.

Summary The efficiency of thermistor mount is defined as the ratio of power absorbed by thermistor to the total input power in mount.Because of losses caused by waveguide wall,casing of thermistor and poor contact etc,the efficiency is always less than one hundred percent. Determination of efficiency of thermistor mounts prossessed practical importance for the error analysis and calibration of powermeter.It is also important for the research or improvement of thermistor mounts. After the publication of first paper concerning the method of measurement due to Kerns in 1949,fine papers have been published successively in foreign periodicals up to 1961.This paper reviews in general the fundamental tocory and methods of measurement,and then derives an expression used to calculate the efficiency in terms of input impedance at voltage minimum.In the formula there is advantage of simplioity in measurement and computation of efficiency.The curves of input impedance at voltage minimum with respect to thermistor impedance are in complete agreement with approximate straight lines given by Ginzton. In this paper measured results have been tabulated for the efficiency of tuned thermistor mount in X-band.The results based on different methods have been compared one another.At the end of the paper the restrictions of application of different methods are discussed and the topics to be considered further are suggested,

热敏电阻接头的效率定义为热敏电阻吸收的功率和实际输入到接头的功率之比。由于热敏电阻接头内部不可避免地存在壁损耗,接触损耗和热敏电阻的玻壳损耗等。这个效率不能达到百分之一百。测定热敏电阻接头的效率对于功率计的误差分析及梭准,热敏电阻接头的研制和改进具有重要的实际意义。自1949年Kerns提出这一个问题以来,至1961年止,国外曾先后发表了五篇有关文献,介绍了五种不同的测量或计算方法。本文首先综述了它们的理论基础,介绍了各种测量方法,并在此基础上导出了利用热敏电阻为某一阻值时接头输入端的节点阻抗值直接计算效率的公式。由此公式,不仅得到一种简单的测量和计算方法,而且由公式作出的输入端节点阻抗-热敏电阻阻值曲线符合Ginzton提出的近似直线性。文中列出了用五种不同方法测试三厘米可调谐波导式热敏电阻接头的效率的实验结果,并从实验和计算两方面比较了这些方法的优劣之处。最后,对这些方法的应用以及有待进一步研究的若干问题提出了粗浅的建议。

本文对高压汽轮机汽缸裂纹补焊技术中存在的两个主要问题——预热和热处理问题,分别提出了现实可行的方法,即: 1.无变形工频感应预热的方法。用这种方法在预热温度范围内加热,可以使经过精加工的汽缸不产生残余变形。 2.跟踪回火的方法。用这种方法处理每一焊道,不但可以使补焊区的金属性能和残余应力与一般回火处理基本相同,而且不致因回火处理而增大工件的变形量。

This paper describes the technological process of casting large aluminium parts—the rotor and casing of rotary blowers.Some important technical problems,such as selection of melting furnace and refining process,elimination of gas holes and slag inclusions are fully discussed herein. Following the comparison and analysis of the functions of various types of pressure chambers, a new design of chamber head-—zigzag toothed type,is offered by Authors.It possesses the advantages of minimum air volume, less floor space,easier manipulation,lower cost and greater efficiency.This article,at the same time,deals with the casting defects which are often oceured in this process,such as shrinkage porosity and crack,and then presents the methods of their elimination. Qualitative data of castings before and after using of this process is herewith enclosed.

本文介绍了大型铝合金铸件——柴油机扫气泵体和叶轮所采用的铸造工艺。作者对试制生产中所遇到的几个主要技术问题,如熔炼设备、气孔、夹渣、精炼方法等作了探讨。文中着重阐述了压力铸造筒设计,作者对各种压力筒作了分析比较后,提出了新的结构型式——错齿式筒盖,其特点是充气容积最小,操作方便,占地少。采用了较小的储气筒,既经济又能发挥最大效果。作者还对压力结晶铸造工艺中容易产生的缩松和裂纹的缺陷作了分析,提出了克服办法。并对压力结晶前后的铸件质量作了对比。
