College of Civil Engineering , Beijing University of Technology, Beijing 100022, China A numerical analysis method for elastic-plastic seismic response of concrete block masonry is presented based on open system for earthquake engineering simulation system. The method simulates concrete block masonry by using equivalent frame model with rigid offsets; the space beam-column elements are simulated by force based nonlinear beam-column elements.

First, we synthesized a new monomer,1-(3\'-aminopropyl)-4-acrylamido-1,2,3-triazole hydrochloride,via click chemistry and its block copolymer with NIPAM, PNIPAM-b-PAPAT,via RAFT polymerization.On the basis of the reaction between amine groups of the PAPAT block and glutaric dialdehyde,core cross-linked and shell cross-linked micelles with inverted structures were prepared at 25℃and 50℃,respectively.

借助于PAPAT嵌段上含有的氨基及PNIPAM嵌段的LCST效应，我们在其20℃和50℃的水溶液中分别制备了CCL胶束和SCL胶束，进一步地，我们利用由Click反应产生的1，2，3-三氮唑环对金属的强络合和稳定作用，分别对CCL胶束的内核与SCL胶束的外壳用金纳米粒子进行选择性修饰。

The aim of this study was to develop a novel amphiphilic functional block poly(ε-caprolactone) bearing ketone groups MPEG-b-P(OPD-co-CL. 2-oxepane-1, 5-dione was copolymerized with ε-caprolatone in which methoxy poly (MPEG, Mn=5 000) and stannous octoate were used as initiator and catalyst, respectively. The syntheses were conducted by bulk and solution polymerization. 1H NMR results showed that peak position and splitting of the polymers synthesized through solution polymerization were consistent with theoretical data, demonstrating the products were designed block copolymers. While in the bulk polymerization, polymer peak position was changed due to their high reaction temperature, suggesting their structural variation.

将带有羰基官能团的4-羰基己内酯和ε-己内酯分别在甲氧基聚乙二醇(MPEG，Mn=5 000)为引发剂，异辛酸亚锡为催化剂溶液和本体体系中开环聚合，合成了两亲性侧基带有羰基官能团的聚己内酯嵌段共聚物MPEG-b-P(OPD-co-CL.1H NMR结果表明采用溶液聚合法合成的聚合物各峰的峰位置和分裂情况与理论一致，证明了产物是实验所设计的嵌段共聚物，而采用本体聚合法合成的聚合物由于温度的影响，聚合物各峰的峰位置发生了变化，说明其结构发生了变化；差示扫描量热法分析结果表明随着OPD单体含量的增加，聚合物的熔点，玻璃化转变温度和熔融焓增加；热失重测试结果表明OPD单体的引入增加了聚合物的热敏感性。

The relationships between the eigenvalues of Jacobi iteration matrix and the block AOR iteration matrix make a very important role in our analysis. Then we prove some sufficient conditions for the semiconvergence of the block AOR method.

利用块AOR迭代矩阵和相应的块Jacobi迭代矩阵的特征值之间所存在的关系，我们证明了求解奇异p-循环线性方程组的块AOR迭代法半收敛的一些充分件。

And New York's rebellion called to me excitedly, this savagery which piled great concrete block on concrete block, topping at the last moment as in an afterthought, with crowns as delicate as pinnacled ice; this lavishness which, without a prayer, pillaged coal mines and waterfalls for light, festooning the great nature-severed city with diamonds of frozen electrical phenomena― it fascinated me, the Asian man, and in it I saw not Milton's Satan, but the one of Blake.

而纽约的反叛精神激动著我的心。它的野性将大块混凝土层层垒起，在最后一刻仿佛踌躇再三才加盖，顶部皆似精巧的冰山；它的挥霍未经祈祷便爲获取光明劫掠煤矿和瀑布，用钻石般璀璨夺目的无数电灯装饰这座超脱自然的伟大城市──这一切令我，一个亚洲人心醉神迷。在纽约身上我看到的不是弥尔顿笔下的撒旦，而是布莱克的撒旦。

Because the miscibility of TLCPs and PSF was poor, a new series of block copolymers—the block copolymers of PSF chain and TLCPs chain were prepared.

首次设计合成了一系列嵌段共聚物—聚砜链段与TLCP链段的嵌段共聚物，研究了其结构、液晶性、热性能。

Meanwhile, the coal block in improving recovery rates and work hard to control a good recovery of the mining face the high points of the underground installation of all reproduced buffer facilities, to reduce the production, transport links block the rate of loss; revised and improved coal quality management practices, standardize management, clear responsibilities in ensuring the quality of washing under the premise of improving coal recovery.
