This paper describes a core management system "JINEGS " to suit the development of a large system "JIGFEX"-a multiple purposed engineerin g structural analysis program. The system "JINEGS" consists of three Ievels, namely a main file, subfiles and records. The construction and functions of the system and some fundamental subroutines to realize these functions are introduced briefly. A flow chart using these fundamental subroutines are indicated.

In this paper, it is investigated how to control static compensator for improving the transient ' stability of power system in the case of a large system connected with a single machine through an external reactance. On the basis of the trajectory on the phase plane and Lyapunov' s direct method, switching line is introduced for controlling static compensator under large disturbance. A two-stage strategy controlling static compensator, consisting of nonlinear bang-bang control and linear regulation, is proposed. The early stage is capable of damping the oscillation most quickly, while the later will ensure that the system smoothly reach its new stable state.Digital simulation has proved that this strategy is excellently effective.

Computing the convective heat transfer in a box-type heater involves solutions of a large system of non-linear equations which contains several hundreds even thousand unknown.The difficulty in solving this system of non-linear equations is the choice of an initial value,close enough to the true solution to assure convergence. A layer to layer method is used from bottom to top to reduce the dimensions of the system. The differential continuative method which has global convergence is used to solve this system of equations. Computations have shown that this method is so efficient that the initial value can be chosen arbitrarily within the rang from 0℃ to 3000℃, the internalstorage required is of that used before, the least computing timeis 112 seconds and the accuracy of calculation is

计算方形加热炉炉膛内对流传热涉及到求几百个甚至上千个未知数的非线性方程组。求解时遇到的主要困难是选择一组足够靠近真解的初值,以保证迭代过程的收敛。为了节省计算机内存,本文采用了自下而上逐层求解的方法;为了克服选择初值的困难,利用微分连续法解此方程组。实际计算表明上述方法有效。
