武汉机场飞行区土方调配大系统优化方案研究

武汉机场是国家重点建设项目。本文提出了机场飞行区土方工程的最优调配问题。它是一个规模庞大的大系统最优规划, 变量多达一千四百九十六个, 一般计算机容量已不够。为此, 在工民建施工领域首次提出了大系统土方调配优化数学模型进行优化, 得出的优化方案可节约经费1073441.29元。所建立的大系统土方调配优化数学模型对工民建等大型土方调配优化有普遍的应用价值。     

压水堆控制棒导向筒结构改进对落棒的影响

为改善横向水力载荷对控制棒导向筒的作用，对靠近上腔室出口管嘴附近的控制棒导向筒（对称的４组：０２－２６，０３－２５，１１－２９，１２－２８）加设了保护套．在秦山核电站压水堆上腔室１４的可视化模拟体中，以水为介质进行了实验研究，把结果与未加设保护套的实验结果作了分析比较，得到了对靠近上腔室出口管嘴附近的控制棒导向筒加设保护套有助于改善流场对控制棒导向筒的水力载荷作用和确保控制棒能按指令在导向筒中自由升降和快速下插的结论．     

实验性脾虚证大鼠血清中微量元素含量的研究

用破气苦降药加饮食失节法复制了大鼠脾虚证模型。采用原子吸收光谱法检测了血清发Ｚｎ、Ｃｕ和Ｆｅ的含量。本研究证明，脾虚证大鼠血清Ｚｎ值明显降低（Ｐ＜０．００１）；Ｃｕ值、Ｆｅ值无明显差异（Ｐ＞００５）；Ｃｕ／Ｚｎ比值上升。用中药加味四君子汤治疗后，血清Ｚｎ值明显回升并高于正常水平（Ｐ＜００５），Ｃｕ值回升（Ｐ＜０．０５），但Ｆｅ值和Ｃｕ／Ｚｎ比值与自然恢复及对照组比较无显著性差异。这说明：１．脾虚组Ｚｎ的降低可能与消化吸收障碍有关；２．加味四君子汤对脾虚证时血清Ｚｎ及Ｃｕ／Ｚｎ比值的变化有明显的调整和恢复作用．

Study on the EM Scattering of Rivets on the Plate

The electromagnetic (EM) scattering by rivets on the conducting plate is studied for the first time by using electric field integral equation (EFIE) in conjunction with the moment method. The surfaces of the rivets and the plate are partitioned into triangular cells, the current distribution on the patches is represented by sub-domain type basis function, the EFIE is translated into matrix equation by the Galerkin method, then the current coefficient is obtained. The results show the properties of radar cross section (RCS) varying with the incident angle when there are rivets on the plate.     

Iterative Method for Constructing Complete Complementary Sequences with Lengths of 2^mN

Complete complementary sequences are widely used in spectrum spread communications because of their ideal correlation functions. A previous method generates complete complementary sequences with lengths of N^nN （n,N ∈ Z^＋）. This paper presents a new iterative method to construct complete complementary sequences with lengths of 2^mN （m,N ∈ Z^＋）. The analysis proves that this method can produce many sequence sets that do not appear in sequence sets generated by the former method, especially shorter sequence sets. The result will certainly increase the application of complete complementary sequences in communication engineering and related fields.
