There exits several MDO algorithms. But they are in our opinion either nonefficient or complicated. So we devised an algorithm called Subspace Approximation Optimization . In the SAO algorithm, the whole system is decomposed into one system-level optimization and several disciplinary optimizations so that a large and complicated problem can be divided into several easy-solving sub-problems. The coupling relationships and the coordination among disciplines are presented by equality constraints and these equality constraints are assigned to relevant disciplines. The optimums of design variables in system level optimization are transferred to discipline level optimization. The optimums of design variables in discipline level correspond to the point that is the nearest to the optimums of design variables in system level. If the optimums of design variables in system level are out of feasible region of discipline 1eve1, linear constraints can be built in the system level optimization using the design variable optimums obtained by the discipline level optimization. The system level optimization would improve the design of the whole system with these linear constraints.

目前，国内外已经发展出了多种飞机多学科设计优化算法，本文的重点是针对协同优化算法的不足，提出了子空间近似优化算法(Subspace ApproximatingOptimization，SAO)，SAO算法中，整个系统的优化问题被分解成一个系统级优化和若干学科级优化，而各个学科之间的耦合与权衡关系则被当作等式约束，这些等式约束将被分配到各个学科级优化中去，系统级优化的任务是寻找整个系统的最优解，而学科级优化的目标函数是以系统级优化分配下来的设计点为圆心的超球半径的平方，因此，如果系统级优化分配下来的设计点在学科级优化可行域内，则学科级优化目标函数为0，反之，则学科级优化的最优点是系统级优化当前设计点距离可行域最近的点。

Our works are not the same in this describable context, but the experimental spirit consisting on cross-subject shows the basic humanistic spiritual state by the visual focus. One adopts field observation in micronarration to reconditely express the inner anxiety in the real life in the inexplicit light and shadow. The other drasticly deconstructs the style of the traditional landscape and expresses the intensity of the existing space in the structure which try to reconstruct another "landscape" order.

我们的作品在言说语境中尽管不同，但共同坚持跨学科的实验精神：一个采用微观叙述的田野观察方法，以视觉聚焦来显现基层人文的精神状态，在暧昧的光与影中，隐秘的表达着现实中内心的焦虑和不安；一个则大刀阔斧地解构传统山水画体例，在结构框架中表达对生存空间的思考，企以重建另一种&山水&秩序。

Through above analysis, solar water heater of homeland possesses the wide market, and anticipates the development of solar water heater in the future five years in South Africa, so as to work out retainable and rising quantities, which provides the basic data for South Africa the environmental benefit.
