A new presentation form for the test result of ship-model propulsion data,i.e.the contours of Δz value difference,thrust difference and torque difference is presented.It shows full data of test result of ship-model propulsion and also provides a basis for extrapolation of any ship length. Based upon the curves of this new presentation,a method for comparing and analysing standard model test,geometrically similar models tests and ship trial results is introduced. For ship-model propulsion test,the author proposes a new method in which both the velocity and revolution are variable.This method is organically combined with three current methods of Continent,England and U.S.S.R.and showing these three methods are special instances for the proposed method.The new method saves much time than current methods,and to some extent it solves the problem of boat-model propulsion test.

本文首先就模型推进试验结果提出一种新的表达形式即:模型△Z值偏差量、推力偏差量和扭矩偏差量曲线图。这种表达形式反映了模型推进试验结果的全部数据,并对任何长度实船情况的换算提出了依据。其次,根据这种表达曲线介绍了对标准模型、几何相似模型以及实船试验等结果进行分析比较的方法。接着,对模型推进试验又提出了新的变航速变转速法,即:各次试验点的转速与航速使之近乎成许多直线簇关系,这新方法能将国外现行的三种试验方法,大陆法(转速与航速要满足某特定关系)英国法(转速与航速无关系),以及苏联法(航速与转速无关系)有机地联系起来,并证明这三种方法都是新方法的特例情况,从而澄清了对这三种方法认为是互相独立的提法。同时,新的试验方法较之现行国外的三种方法要节省很多试验时间。最后,新方法在原理上解决了模型艇的推进试验问题。

This paper describes briefly the experimental results of resistance tests,pro- peller open water tests and self-propulsion tests of five geometrically similar models of a 24,000 DWT oil tanker.The tests were carried out at Ship Hydrodynamics Laboratory of Shanghai Jiao Tong University.The following conclusions reached on the basis of the analysis of experimental results may be useful for future refer- ence in ship model experimental research. (1)The form factor method (three-dimensional method) is more reasonable than the traditional Froude's method(two-dimensional method) for extrapolating model to ship resistance. (2)There is an appreciable scale effect on wake fraction,and the wake fraction decreases as the size of models increases. (3)The scale effect on thrust deduction coefficient is small,which may be con- sidered approximately constant for models greater than 5 meters in length. (4)The relative rotative efficiency decreases as the size of models decreases, but its scale effect can be neglected when the diameter of the model pro- peller is greater than 120 mm.and the length of the ship model is longer than 4 meters.

本文简要介绍上海交通大学船模试验池对于24000吨油轮五艘几何相似船模的阻力试验、敞水试验及自航试验的结果,根据试验结果分析得出的下列结论可供今后船模试验研究参考之用。1.在阻力换算中,形状因子法(三因次法)较传统的付汝德法(二因次法)更为合理。2.伴流分数有明显的尺度效应,随模型尺度的增加而下降。3.推力减额分数的尺度效应较小,当船模长度大于5米时可视力常数。4.相对旋转效率随模型尺度的减小而下降,当桨模直径大于120毫米和船模长度大于4米时方可忽略其尺度作用的影响。

The problem of four generation straton weak coupling matrix is discussed. In several possibilities, the V-A coupling for the electroweak interaction of the four generation stratons is chosen and a coupling matrix of charged weak currents is proposed. It is a direct extension of K-M matrix. In order to illustrate the validity of the weak coupling matrix, two examples are given. The first example is used for the calculation of CP violation of K decays. In the second example, four generation weak coupling matrix expressed by mass of straton is calculated by means of horizontal gauge. An unexpected result is that the main decay mode of b straton is b→c+W~-. But in the case of 3 generations, the main decay mode of b straton obtained by the entirely similar model is b→u+W~-. Therefore, if this mode of horizontal gauge be verified in further experiments, there would be a reason for the extension of 3 generations to 4 generations.

本文讨论了四代层子的弱耦合矩阵的问题。在几种可能性中,选择了四代左手流方案。建议了一种带电弱流的耦合矩阵,它是K-M矩阵的直接推广。为检验这个弱耦合矩阵做了两个例子。例一,用它算了K介子衰变的CP破坏。例二,用水平规范算出了以层子质量表示的四代弱耦合矩阵。一点意外的收获是b层子的主要衰变道是b→c+W~-。而在三代情况下,完全相同的方案得出的b层子的主要衰变道是:b→u+W~-,因此,如果尔后的实验选择了这种水平规范的方案,那么由三代层子扩充到四代层子则找到了依据。
