利用分块成向量的方法证明了MnMn(F为域F上所有n×n矩阵构成的乘法半群上的n×n拟正交矩阵组至多含有n个矩阵，利用方程组的解的理论证明了Mn中与给定矩阵A构成两两拟正交矩阵组的矩阵个数不超过n-Rank+1，从而得到Mn上保持拟正交性的线性映射φ要么是降秩的或者保秩的映射，要么φ的值域中含有幂零元。

From his selection of Beijing and Lhasa as exhibition locations in 1985 to his trips to China to create new art, we can see that Rauschenberg had a particular affection for this country. Rauschenberg's passing now makes this set of twelve prints about China the last product of his long and illustrious career. Each of the twelve pigmented inkjet prints of photo assemblages collectively entitled "The Lotus Series" contains a lotus flower, ten of which employ the same stone or concrete lotus added to the prints via photogravure, while two include a picture of the same lotus flower on the water's surface.

从他自1985年选择北京和拉萨两地做自己的个人展览，到他几次来中国创作作品，就可以看出劳申伯格是一个对中国有感觉的艺术家，而他的仙逝，让这组中国题材的作品竟成了他最后的作品，这是12张一组的照片合成的喷绘版画，题为《莲花系列》，每一张都有荷花，其中10张都采用同一个水泥材料或者石雕的荷花，另两张带有荷花的作品都是在画幅上半部使用了同一张王莲的照片。

Based on the research of oil geology characteristic of Xing'anling group in Sudeerte area,by researching the three main accumulation factors source rock,transform pathway and trap for oil formation, showed that the main transform pathway for oil migration in K1n are source rock,unconformity and sand body,and trap related with fault is the main place for oil migration.

在苏德尔特地区兴安岭群石油地质特征研究的基础上，对其油成藏的源岩、输导通道和圈闭3个主要成藏要素进行了研究，得到南屯组是其主要源岩，源断裂、不整合面和砂体是油运移的主要输导通道，与断层有关的圈闭是油聚集的主要场所。

Methods: The sample consisted143 children which were in early permanent dentition of ClassⅡ,Division 1malocclusion .Pre-and post-treatment study models were assessed using PeerAssessment Rating index. According to the outcome of treatment, thesecases were classified into three types as "worse, no different","improved"and"greatly improved". The cephalometric analysis and Model Analysis werepreformed with pretreatment lateral cephalograms and study models for"improved"and "greatly improved"cases."T"–test was assessed to find out thesignificant difference between the extraction and nonextraction, and the resultsincluding age factor were analyzed by stepwise discriminant analysis.

应用PAR 指数对矫治前后的143 副恒牙早期的安氏Ⅱ类1 分类错牙合患者牙牙合模型进行评估分析，按矫治结果等级分为三类A、变坏或无改善，B、改善，C、极大改善，然后将B、C 两类患者矫治前的头影测量片及模型分析数据按拔牙与未拔牙进行成组t 检验的单因素分析，找出两组间有显著差异的软硬组织和牙牙合模型指标，对这些指标合并年龄因素进行逐步判别分析。

By means of sedimentary and diagenetic study, this paper analyzed the origin of sand bodies, diagenesis, pore evolution, reservoir characteristic and its influencing factors of Shahejie Formation in Huanghua Depression.
