You go to your own room and rest, darling.' But no sooner had she gone, than he rang for Mrs Bolton, and asked her to take a hand at piquet or bezique, or even chess.

他们俩依旧守着从前的习惯，晚上直到点钟，是要在一起度过的，他们谈着，或一起读着书，或校阅着他的草稿。

Generally, the Fresenl lens is used for collimation and its structure is planeconvex, but the analysis and comparison of the biconvex and the plane-convex Fresenl lenses with P-W method show that the biconvex Fresenl lens is better because of its specific imaging requirement. The two kinds of the Fresenl lenses were modeled in ZEMAX to validate the conclusion.

从应用角度看，菲涅尔透镜设计属于准直系统，一般采用平面结构，但由于其成像要求的特殊性，通过运用P-W方法进行分析和比较，结果表明：曲面的设计较之于平面更具优势，并在ZEMAX中分别对2种菲涅尔透镜进行建模，验证了结果的正确性。

Secondly, we discuss the boundary value problem of two dimensional biharmonic equation in a rectangular field and its variational problem,discretize it by using dual tensor product of and the direct product and lining up of matrices, we get some special matrices which are the presupposition in exploring the fast computation, then solve the system of linear equations.

其次本文讨论了矩形域上二维双调和方程边值问题及其相应的变分问题，利用二元张量积小波分析和矩阵的直积、拉直技巧将变分问题离散化，从而使求解偏微分方程问题变为求解线性方程组的问题。一维情况两组基的张量积下得到的系数矩阵分别为块状七对角阵和稀疏矩阵。这些特殊结构为以后快速算法的研究打下一个基础。

Similar to [KV2], for a Dynkin-algebra A, we prove that there is a bijection between the bi-aisles in Db and thestrictly full triangulated subcategories of Db which are closed under direct sum-mands.

运用[KV2]中的技巧，对Dynkin型k-代数A的模范畴的有界导出范畴Db，我们证明了其上的双aisles与其上的严格的且关于直和项封闭的三角满子范畴存在着一一对应的关系。
