Here is discussed the application of differential gear mechanism for variable speed control, particularly for varying bobbin speed of flyer frames. For all three types as shown in Fig. 1, we get the same speed relationship as follows: n_z=bn_o+(1-b)n_y n_o-Constant speed of main shaft. n_y-Control speed from some speed-varying mechanism such as friction disk or belt cone. n_z-Output varying speed for some definite ends. b-Numerical constant dependent on gear ratios, given in Tab. 3 for all the three different...

Here is discussed the application of differential gear mechanism for variable speed control, particularly for varying bobbin speed of flyer frames. For all three types as shown in Fig. 1, we get the same speed relationship as follows: n_z=bn_o+(1-b)n_y n_o-Constant speed of main shaft. n_y-Control speed from some speed-varying mechanism such as friction disk or belt cone. n_z-Output varying speed for some definite ends. b-Numerical constant dependent on gear ratios, given in Tab. 3 for all the three different types. Straight lines are plotted as in Fig. 2 to show the above relationship for different values of b. In Fig. 3 is given the relationship of turning moments and turning speeds at different values of b. In Fig. 4 is given the directional relationship of the mechanical power trans. mitred in the differential gear mechanism. The conclusion is: When the required speed variation is within narrow limits, the use of differential mechanism can reduce the mechanical power transmitted by the speed-varying mechanism, thus increasing its sensitivity and accuracy of control. See equation (12).

本文讨论粗纱机差动机构中周转轮系的应用——变速控制。对于图1中三种类型的周转轮系,可以得出统一的转速关系式: n_z=bn_o+(1-b)n_y 在图2中根据上式按下同的b值作出各直线以表示其间的关系。在图3中按不同的b值作出转矩和转速之间的关系图。在图4中表示出在各种情况下周转轮系和变速装置间的功率路线图。根据(12)式我们可以得出这祥的结论:当所要求的变速范围不大时,采用了周转轮系可以使通过交速装置的功率大为减小,因而增加变速控制的灵活性和准确性。

In this paper are reported results of experimental invertigation of electromagnetic and optical radiations produced by single bubble cavitation. After observation and brief theoretical analysis of growth and collapse of single bubble, these radiations were studied experimentally. The pre-sense of electromagnetic radiation was confirmed. In contrast with the statistical conclusion drawn by other workers for optical radiation, generations of optical and electromagnetic radiations are found to be simultaneous at...

In this paper are reported results of experimental invertigation of electromagnetic and optical radiations produced by single bubble cavitation. After observation and brief theoretical analysis of growth and collapse of single bubble, these radiations were studied experimentally. The pre-sense of electromagnetic radiation was confirmed. In contrast with the statistical conclusion drawn by other workers for optical radiation, generations of optical and electromagnetic radiations are found to be simultaneous at the moment of bubble collapse. Then the effects of varying liquids and gases and of varying speeds of bubble collapse on electromagnetic and optical radiations were inverstigated. Experimental results show that, although electromagnetic radiation as well as optical radiation occur as predicted by Frenkel, the mechanism cannot be explained by his hypothisis. It is considered that generation of these radiations may be related to the generation of micro-shock wave in the bubble at the moment of its collapse.

本文报导关于单一气泡空化所产生电磁辐射和光辐射的实验研究.在观察和简略理论分析单一空化气泡的生长和闭合运动后,用实验方法研究了这两种辐射.首先肯定了电磁辐射的存在;并与其他一些有关光辐射的工作所作统计性的结论有别,明确肯定电磁辐射和光辐射同时发生在气泡闭合时刻.接着研究了几种液体、几种气体以及气泡闭合速度对两种辐射的影响.实验结果表明,虽然存在有Frenkel所预言的电磁辐射和光辐射,但其机制不是他提出的假说.初步看来,两种辐射的产生可能与闭合时气泡中所产生的微骇波有关.

The engineering background of this paper is the project of a elevatorfor a ship crossing over a dam of the Yangtze Gorges.The elevator hasa box for loading water and ships.While the ship is moving in the boxwith varying speed,the variations of water level in the box,water mo-ment acting on the box and the least clearance between the ship bottomand the box are concerned.The water levels on both sides of the boxgate may be different,it is also under the consideration.The above problems are turned into two partial differential equations,i.e..a continuity equation and a one-dimensional unsteady Bernoulliequation.This paper gives the solution of the simultaneous equationsunder the corresponding boundary and initial conditions by the finite dif-ference method.The results compared with the experiments are reaso-nable.

为探讨船舶变速出入大坝升船机的承船厢时的流体动力过程,本文发展了一个一维不定常流体运动的理论。它可以描述船舶出入承船厢时的水面波动,承船厢受到的流体动力弯矩,以及船底离开厢底的最小间隙等。当承船厢闸门打开时,厢内外的水面高度可能不同,本文考虑了这个水位间断的发展和它对船体运动的影响。方程按差分方法离散。计算与试验作了比较,结果令人满意。
