Secondly,the author puts emphasis on "the simple linear programming"----the teaching design's whole blueprint in high school, the strategy on how to deal with the relation between dual inequality and linear programming; how to establish the linear programming model; the strategy on how to find the optimal solution; the several situations of the optimal solution's positions.

其次重点研究了"高中简单的线性规划"教学设计的总体构想；处理线性规划与二元一次不等式关系的策略；如何建立线性规划模型；线性规划问题中最优解的找法策略，最优解的位置的几种情况。

Some constraints are selected, and omitted according to the most-obtuse-angle principle. The smaller problem is solved with the simplex method. Then the omitted constraints are added to restore the original problem. If all the constraints are satisfied, then a basic optimal solution is reached. In the other case, the dual simplex method is used to obtain the basic optimal solution.

该算法依据最钝角原理略去部分约束得到一个规模较小的子问题，用原始单纯形算法解之；再添加所略去的约束恢复原问题，若此时全部约束条件均满足则已获得一个基本最优解，否则用对偶单纯形算法继续求解。

And an optimal dynamic model of resource disposal is obtained by applying the optimal control theory.

自然资源的开发利用就是通过一定的手段和方法来转化和利用这些自然物质和能量，以此来满足人类生产和生活等各方面的需求。

As a result, the concept of an optimal set of elementary siphons is proposed and also the algorithm which can be finished in polynomial time to find such a set. With the set of optimal elementary siphons, net supervisors can generally produce maximalreachable states.

但是上述理论虽然只需要控制基本信标即可以控制整个系统，但是由于从属信标满足一定的可控性条件才能完全受控，这意味着在控制算法的生成过程中所有的信标都要参与，从而大大增加了系统控制的复杂性。

He proved that:if the total moving times of mesh M is a finite number and independent ofΔt andh.the L2-norm error estimate is optimal;if Mh is independent ofΔt and bounded,energy norm error estimate is optimal.

并证明了当网格变动次数M是不依赖于Δt和h的有限数时，近似解与真解的L2误差估计是最优的；当Mh不依赖于Δt且有界时，能量模误差估计最优。

The aims of this paper are to derive the optimal error estimates of eigenpairs, i.e. the optimal error estimate of eigenvalues, and the new error estimates of velocity, pressure including the L~2 - norm and energy norm, respectively, in which the L~2 - norm estimate of velocity on anisotropic meshes has not ever been seen in the precious literature.

对于Stokes特征值问题本文不仅得到了征值对的最优误差估计即：特征值和流速压力的零模和能量模以及压力的能量模最优误差估计，其中在各向异性网格下对此问题的零模估计尚未见报道。

In the case of bulk materials, the optimal phase only correlates with experimental conductions. But for nanomaterials, the equivalent resistance and capacitance R(subscript ins and C of MIS structure vary under illumination that will result in great changes in the optimal phase.

对於体相材料，"最佳相位"仅与测量条件有关；对於纳米材料等体系，光照可以改变MIS结构的等效电阻R(下标 ins、等效电容C(下标 ins，从而将引起最佳相位角的显著变化，使"最佳相位"与所研究材料的特性直接关联起来。

The result shows that multiple inlet is better than single inlet, and that inlet with buffer is better than that without buffer. Other optimal design structures are also adopted. The gas manifold with optimal structure make oxygen much evener for each cell.
