Systems of inqualities,the minimum or maximum of a convex function over a convex set,Lagrange multipliers,and minimax theorems are among the topic treated,as well as basic results about the structure of convex sets and continuity and differentiability of convex functions and saddle-functions.

其中对不等式系统、凸集上的凸函数的极小或极大、拉格朗日乘子和极小极大定理做了专题论述，同时对凸集的结构和连续性以及凸函数的可微性和鞍点函数的基本结果做了介绍。

For the sky tour, one can take a solar energy light aircraft and, in the manner of a bird, soar freely about. For the water tour, one can take the tour boat. All boats are run on a fixed schedule and travel pre-determined routes . One can either go up the Ming River in a boat, to see the world famed cliff frescos of Balai Mountain , or take the divers' shuttle and enjoy the delight of being a fish. As for land tour, one can go donkey or horseback riding over hill and dale. However, I recommend Mr. Wen skip the last one.

天上是乘坐太阳能轻型飘浮机，可以像鸟一样，任意翱翔天际；水里可乘坐游轮，有固定的班次及航向，可以溯明江到巴莱山看闻名中外的山崖壁画；再不然是乘坐潜水鱼梭，可以享受做鱼的乐趣；至於地上可以乘驴骑马，翻山越岭，不过我建议文先生不要考虑这最后一项。

This thesis focuses on studying the matrix equa-tion problem systematically, and proposed an abstract algorithm of solving the matrixequation with constraints, and established a strict convergence theory. Using this algo-rithm, we can solve the sets of matrix equation satisfying some constraint conditions,such as symmetric, antisymmetric, centrosymmetric, centroskew symmetric, re?exive,antire?exive, bisymmetric, symmetric and antipersymmetric, symmetric orthogonalsymmetric, symmetric orthogonal antisymmetric, Hermite generalized Hamilton ma-trix;So we can solve the problem with this algorithm, if the set of constrain matrixcan make a subspace in matrix space, and this algorithm also can solve the optimalapproximation and least squares problem. So this abstract algorithm has universal andimportant practical value.

本篇硕士论文系统地研究了此类问题，并找到了求解约束矩阵问题的抽象算法，并建立严格的收敛性理论，利用这一算法可求解约束条件为对称矩阵、反对称矩阵、中心对称矩阵、中心反对称矩阵、自反矩阵、反自反矩阵，对称正交对称矩阵、对称正交反对称矩阵、双中心矩阵、Hermite广义Hamilton矩阵等；可以说只要约束矩阵集合在矩阵空间中构成子空间，都可以考虑用此算法求解，而且这一算法还能把矩阵方程解及其最佳逼近，最小二乘解及其最佳逼近统一处理，因此本文算法有普适性和重要的实用价值。

Note: Richard Barber, the Knight and Chivalry, New Jersey, 1976 edition, page1 It is not easy to get a good war horse, some horses are only suitable for pulling carts or plowing while some looks beautiful and strong but that would be only suitable for general riding and traveling instead of using in the complex, volatile, disordered and fighting battlefield.

能得到一匹优秀的战马并不是一件简单的事情，有些马只适于拉车、耕田；也有些马看似健美，但只可用于一般性骑乘和旅行，不宜在复杂多变、混乱厮杀的战场上使用。
