The main research contents are stated asfollow: 1. Simplified analysis method of space grids structuresDouble-layer space grids have been assumed as sandwich plate, and are analyzed bythe nontraditional theory of plate with consideration of shear deformation and threegeneralized displacements. Using the theory of energy variation, simplified methodsfor bending, stability and vibration analysis of double-layer space grids have been putforward based upon the idea of split rigidity. The formulas for calculating internalforces, displacements, critical load and natural frequency have been given out. Set thestable cables and bearing cables in hyperbolic paraboloid cable nets are all replaced bytruss-cable to form truss-cable nets structures. Natural vibration analysis method fortruss-cable nets structures has been put forward using the energy variation method andRayleigh method.

The method transfers the observed data from space domain to 2-D space-time domain by exploiting the cross-correlation of the array outputs,and a large amount of virtual elements are generated through space-time processing.Therefore the constraint over the array configuration and the element identity can be significantly weakened,which means the matching subarray is no longer needed and the advantage of the traditional DOA matrix method,such as automatical parameter alignment and no need of 2-D search,is still available.

该方法在保持原DOA矩阵方法无需二维谱峰搜索和参数配对等优点的基础上，利用阵元输出之间的互相关关系将空域的阵列观测数据变换到时空域，通过空时二维处理在时空域中衍生出大量虚拟阵元，从而大大减弱了传统方法中对阵列结构、排布方式和阵元一致性的约束，不需要匹配子阵，无冗余阵元与孔径损失，并适用于阵元排列不规则的阵列。

On the other hand,because of people"s inconsideration of users" humanistic needs both physically and psychologically , it has put much disadvantageous effect on the using and development of the public space of commercial center, such as traffic jam, insufficiency of walking space, monotonous landscape space and have not embodying enough the regional culture and characteristics of the city.

一方面，它解决了人们步行、购物、休闲三者有机结合的难题，将人从商业街道空间的附属者提升到了主体地位；另一方面，由于过于注重商业建设，对使用者的生理、心理需求考虑不够。

At first, four feature attributes were built by content of DNA's four bases. By increasing length attribute of DNA sequence in the space to extent the feature attribute space. Finally, the classification of hyperplane was obtained on the basis of available samples training by using SVC in the feature attribute space.

根据SVM分类器的要求建立特征属性空间，首先由每个DNA中4个碱基的含量得到4个特征属性，然后在此空间中扩充DNA序列长度的属性，最后根据SVM分类器对已知的DNA分类样本做训练得到分类超平面。

By extending the concepts of supremum and infimum in real space to the casein any finite-dimensional Euclidean space a weak supremum set and infimumset theory with respect to cones for the set in finite-dimensional Euclideanspace is developed,and several similar properties to the set in real space are ob-tained,with the concepts of this weak supremumset,w-D-conjugate maps and w-D-subdifferentials theory for the point-to-setmap are developed,and its several properties and its relationships with weakefficient solutions of the multiobjective programming are studied.

推广实空间中上、下确界的概念至任意有限维欧氏空间，建立了有限维欧氏空间中集合的锥弱上、下确界集理论，得到了与实空间中十分相似的性质。借助于这一理论，应用上、下确界的概念，给出了点集映象的w-D-共轭映象及w-D-次微分理论，并研究了它们的若干特性及其与弱有效解之间的关系，此外还讨论了弱鞍点问题。

In Chapter 3, we discuss the other orthogonalities in in Banach space, and give some properties of them. The emphase of the chapter is to study the relations of Birkhoff orthogonality, Isosceles orthogonality and Pythagorean orthogonality, and it is proved that if one of these induces another, then the space is an inner product space.
