The speed- fluctuation of the loom crank shaft has much effect on the study of loom action and dynamic analysis. Without consideration of the fluctuation of speed, the result of any study will deviate from the actual condition to a great extent. Therefore, the calculation of the speed of the loom crank shaft and the determination of the moment of inertia of the "two shafts" (the crank shaft and the cam shaft with all the rotating parts mounted on them) is of important significance to the loom designers...

The speed- fluctuation of the loom crank shaft has much effect on the study of loom action and dynamic analysis. Without consideration of the fluctuation of speed, the result of any study will deviate from the actual condition to a great extent. Therefore, the calculation of the speed of the loom crank shaft and the determination of the moment of inertia of the "two shafts" (the crank shaft and the cam shaft with all the rotating parts mounted on them) is of important significance to the loom designers and research workers. This paper is first given a brief statement of the significance of the speedfluctuation of the loom crank shaft and the balance of energy. Then it suggests a method of calculating the speed-fluctuation of the loom crank shaft and determining the magnitude of the moment of inertia of the "two shafts". The main principles adopted here are: first, the use of an equivalent moment of inertia of the "two shafts" and the beating mechanism; second, broadening the sense of the work done by the resisting torque of the loom; third, assuming that the consumed energy of the picking mechanism is not directly related to the speed-fluctuation of the crank shaft. Thus, the mutual effect of the balance of energy and the fluctuation of speed which existed in Prof. A. P. Maleshef's method is now eliminated. Therefore, it is possible to derive two equations, (11) and (14), for Calculating.the speed-fluctuation of the loom crank shaft and the moment of inertia of the "two shafts" directly, instead of the cut and try method given by Prof. A. P. Maleshef. Finally, two examples are given to justify that the suggested method is practically accurate.

織机迴轉不均勻性对研究织机的运动学与动力学有很大的影响。不考虑迴轉不均匀性,对織机进行任何研究都是脫离实际的。因此研究织机迴轉不均匀性和“两軸”轉动惯量的計算,对設計者和研究者而言都是有重要意义的。本文首先对織机迴轉不均勻性及能量平衡作了簡要的說明。然后提出一个計算方法,它的主要論点是:采用了相当转动慣量和推广了阻力功的意义,并且假設投梭机構所消耗的能量与迴转不均勻性无直接影响。这样就可以消除能量平衡与迴轉不均勻性相互的影响,从而导出了兩个公式(11)与(14)用以直接地計算迴轉不均匀性和兩軸轉动慣量,不必采用馬雷舍夫教授的逐次漸近法。最后用兩个实例計算証实了这个計算方法在实用上是正确的。

本文把一类气动微震机构工作过程,抽象为一个二阶动力系统。对其运动 过程进行动力学分析。文中采用了“后继点”方法,使人们易于了解系统震击 的过渡过程,根据工程技术对震击过程的要求,推出了有关选择系统参数的计 算公式,并给出一种震击周期(或频率)的计算方法。

In this paper, the strict physical implication of diagnostic analysis and its re-lation to dynamic analysis, a more broad field, are discussed. The storm in August, 1975 is used as an example to show what we may get from diagnostic analysis.

本文是以扼要介绍工作[2]为中心,简要叙述了诊断分析的意义、起源和它的正确含义。强调指出,现代的诊断分析是一种狭义的动力分析,它的计算是以准确的观测和天气学分析为基础,计算结果也需要较准确的天气学、动力学的分析与判断。总之,它是广义动力分析的组成部分和基础。 [2]主要是利用较完全的ω方程,对于与7503号台风密切相关的“75.8”河南特大暴雨进行了诊断分析。计算结果指出潜热释放是导致上升运动的最重要的物理过程。根据计算的ω和观测到的水平风场,分析了包括7503号台风和河南暴雨区在内的大范围三维流场及其变化。指出:由于北方弱冷空气和登陆的7503号台风的相互作用,导致了河南特大暴雨过程;在它们的相互作用下,7503号台风的路径强度和结构相应发生有规律的变化。
