On the basis of the fundamental principle of three-phase induction motors we have obtained a new method of predetermining motor parameters in terms of specified performances by using the ratios of parameters.The characteristic feature of this method is that the derived expressions are simple and convenient for use. Before making design calculations of the motor, its inherent parameters can be quickly predicted according to the specified performances. Hence, in the course of making necessary modifications, one can control the design data in such a way that the parameters calculated from the design procedure will conform to those predetermined values for the specified performances, so that the desired performances of the motor can be secured and aimless calculations are avoided. Besides, we have derived some approximate formulae for predicting the two ratios, and the accurate values of which can be obtained only by "trial and error". Their approximate values necessary for the preliminary design can also be conveniently predetermined according to the specified performances. Thus, the number of repetitive calculations can be greatly reduced.Calculated examples show that the results obtained from the derived formulae are satisfactory.

本文从三相异步电机的基本原理出发,利用参数的比值,得出一个用规定的运行性能来预定异步电动机参数的新方法.这个方法的特点是:参数的表达式较为简单,应用也很方便,根据某些规定的运行性能,在电机的电磁计算之前,能够较快地预算出应有的参数数值.因此,在不可避免的调整计算过程中,可以有目的地控制有关数据,使按电磁计算程序算出的各种参数数值,符合用规定运行性能预先求出的应有参数数值,从而保证了电动机应有的各种运行性能,这就有力地减少了计算过程中的盲目性.另外,对计算中靠逐步逼近才能达到较正确数值的两个比值——k_E=E_1/U_1及k_1=(I'_(2N))/(I_(1N)),也导出了近似公式,根据某些规定的运行性能,可以简便地预算其近似值并作为取值时的依据,因此可减少不少重复计算. 实例验算表明,按给出公式计算的结果是令人满意的.

In the new method a plane wave with a particular direction of polarization is used to illuminate the target.When the ratio of the components of the same direction for two different incident angles was measured at observation points, then the ε of the target can be evaluated.Expression for evaluation of ε is derived.

A numerical method for calculating a fully-coupled model of one-dimensional two-phase nozzle flow is described in brief. Governing equations are derived. The Runge-Kutta-Gill method is adopted to solve the equations numerically. The solution for uniform acceleration of gas phase is utilized as an approximate solution for the dimensionless distance x*(=x/L) = 0 to 0.02,i.e.ug = ax*. The initial value of a is determined by a trial and error approach and then checked at the throat. The solution is continued to the throat where the conditions must be satisfied. To eliminate the singularity of the equation, a superseding variable is introduced. The computations are performed for velocity-lag as well as temperature-lag of five parsticle sizes and two ratios of particle to gas flow rates.Temperature, pressure and velocity distributions of both gas and particle along the length of the nozzle are also obtained.In addition, various modes of one-dimensional two-phase nozzle flow have also been briefly reviewed.
