| 1 | 前瞻性和回顾性心电门控冠状动脉64层CT成像:影像质量和病人放射剂量的对照性研究显示文摘目的比较一组接受前瞻性心电门控64层CT冠状动脉成像病人及另一组接受回顾性心电门控64层CT冠状动脉病人的成像质量及病人放射剂量。方法本研究依从HIPAA法案并得到了机构审查委员会的批准。由于设计是回顾性研究故不需要知情同意。2位独立阅片者分别对100例病人心脏CT成像(每组各50例)的冠状动脉进行分段影像质量评分和综合评分。计算观察者间偏差。记录对应实际扫描Z轴长度的病人放射剂量,以Z轴长度为12cm的典型心脏计算标准化剂量。结果2组病例的临床特征及CT参数匹配良好。 | W.P.

| 5 | “法律与发展研究”的特性显示文摘象在第一章中讨论中所指出的那样,“法律与发展研究”(SLADE)是一种用定量的资料和方法所进行的知识探讨,旨在建立和检验理论。我们感兴趣的领域首先是法律与发展,故早在这种探讨的设计时就有必要合理地选定两个关键性概念的准确含义;这两个概念是“发展”(我们限定它意指“发展中国家的社会变化”)和“法律”(指“法律制度”)。这样一来,对被我们称作“法律文化”的第三个变项的需要就变得显而易见了。 | J.H.梅里曼 D.S.克拉克 L.M.弗里德曼 俗僧 | 1990 | 比较法研究1990,4,2: | 16 |
| 6 | STUDY ON PTA CLAD (Cr,Fe)_7C_3/γ-Fe CERAMAL COMPOSITE COATING显示文摘A wear resistant (Cr,Fe)7C3/γ-Fe ceramal composite coating was fabricated on substrate of a 0.45% C carbon steel by plasma transferred arc (PTA) cladding process using the Fe-Cr-C elemental powder blends. The microstructure, microhardness and dry sliding wear resistance of the coat- ing were evaluated. Results indicate that the plasma transferred arc clad ceramal composite coat- ing has a rapidly solidified microstructure consisting of’ blocky primary (Cr,Fe)7C3 and the inter- blocky (Cr,Fe)7C3/γ-Fe eutectics and is metallurgically bonded to the 0.45%C carbon steel sub- strate. The ceramal composite coating has high hardness and excellent wear resistance under dry sliding wear test condition. | J.B. Liu J.H. Huang L.M.

| 7 | 中国共产党与中央苏区妇女运动显示文摘1931至1934年,中国共产党在农村妇女中成功地发展了一场革命运动.通过这场运动,生活在党领导下的农村根据地区域的大部分妇女参加了革命斗争.在这个过程中,她们提高了自己的地位,扩大了作用及其活动.本文将对中共在苏区把解放农村妇女的斗争与彻底革命努力结合起来的政策,对为保护妇女广泛参加社会革命而逐渐发展起来的方法进行探讨. 确立方向:1931 在苏区革命运动的发展中,1931年是关键的一年.早在4年以前,即1927年,主要由城市知识分子组成的一批党的领导人员,被迫把重点由城市转移到农村. | 凯塞L.M.瓦尔克 曾成贵 | 1992 | 党史研究与教学1992,,2: | 7 |
| 8 | Microstructure Dependent Fatigue Cracking Resistance of Ti-6.5Al-3.5Mo-1.5Zr-0.3Si Alloy显示文摘Fatigue cracking behavior from a notch was investigated at room temperature for Ti-6.5Al-3.5Mo-1.5Zr-0.3Si(TC11) alloys with four different microstructures obtained at different cooling rates from the β transus temperature.It was found that the alloy with lamellar structures consisting of α/β lamellae or acicular α' martensite laths had a higher fatigue crack initiation threshold from the notch,while the bimodal structure with coarse α grain had a lower fatigue cracking resistance.The alloy with α/β lamellar structure showed a higher fatigue crack growth resistance.The length scales of the microstructures were characterized to correlate with fatigue cracking behavior.Fatigue cracking mechanism related to microstructures was discussed. | Z.M.

| 9 | 美国法的未来显示文摘许多人感到我们的法律太多了,美国人为了自己的利益过多地卷入了法律、诉讼和法律程序之中。确实,美国社会似乎是堕入一张法律之网中——比其他国家或这个国家的过去都更是这样。一些人认为我们正在越来越深地陷入深浅难测的法律谷底之中。一家全国性杂志为这样的'诉讼社会'而哀叹,它抱怨在这样一个社会里,没完没了的诉讼导致'信任受到损害,创造活力受到压抑'。 | L.M.弗里德曼 贺卫方 | 1991 | 环球法律评论1991,13,6: | 7 |
| 10 | A performance comparison of multi-objective optimization algorithms for solving nearly-zero-energy-building design problems显示文摘Integrated building design is inherently a multi-objective optimization problem where two or more conflicting objectives must be minimized and/or maximized concurrently.Many multi-objective optimization algorithms have been developed;however few of them are tested in solving building design problems.This paper compares performance of seven commonly-used multi-objective evolutionary optimization algorithms in solving the design problem of a nearly zero energy building(n ZEB) where more than 1.610 solutions would be possible.The compared algorithms include a controlled non-dominated sorting genetic algorithm witha passive archive(p NSGA-II),a multi-objective particle swarm optimization(MOPSO),a two-phase optimization using the genetic algorithm(PR_GA),an elitist non-dominated sorting evolution strategy(ENSES),a multi-objective evolutionary algorithm based on the concept of epsilon dominance(ev MOGA),a multi-objective differential evolution algorithm(sp MODE-II),and a multi-objective dragonfly algorithm(MODA).Several criteria was used to compare performance of these algorithms.In most cases,the quality of the obtained solutions was improved when the number of generations was increased.The optimization results of running each algorithm20 times with gradually increasing number of evaluations indicated that the PR_GA algorithm had a high repeatability to explore a large area of the solution-space and achieved close-to-optimal solutions with a good diversity,followed by the p NSGA-II,ev MOGA and sp MODE-II.Uncompetitive results were achieved by the ENSES,MOPSO and MODA in most running cases.The study also found that 1400-1800 were minimum required number of evaluations to stabilize optimization results of the building energy model. | Mohamed Hamdy Anh-Tuan Nguyen Jan L.M.

| 11 | NUMERICAL SIMULATION OF SUCCINONITRITE DENDRITIC GROWTH IN A FORCED FLOW显示文摘Numerical simulation based on phase field method is performed to describe solidification process of pure material in a free or forced flow. The evolution of the interface is showed, and the effects of mesh grid and flow velocity on succinonitrite shape are studied. These results indicate that crystal grows into an equiaxial dendrite in a free flow and into an asymmetrical dendritic in a forced flow. With increasing flow velocity, the upstream dendritic arm tip grows faster and the downstream arm grows slower. However, the evolution of the perpendicular tip has no significant change. In addition, mesh grid has no influence on dendritic growth shape when mesh grid is above 300×300. | Z. Chen C.L. Chen L.M. Hao | 2008 | Acta Metallurgica Sinica(English Letters)2008,21,6: | 6 |
| 12 | 青藏高原东部及其邻区力学耦合的岩石圈变形模式显示文摘根据青藏高原东部及其邻区布设的143个宽频带固定和流动地震台站的远震记录的SKS波分裂分析获得了各台站的快波偏振方向和快慢波之间的时间延迟。SKS分裂分析结果总体上反映了高原东部的上地幔物质流动方向,即高原内部表现为环绕喜马拉雅东构造结的顺时针旋转。在造山运动过程中有关岩石圈地壳和地幔力学耦合的造山变形方式,用从GPS和第四纪断裂滑动速率数据确定的地面变形场和由地震波各向异性数据推断的地幔变形场联合分析来定量求得。在青藏高原东部和云南、四川等地区新近快速增加的GPS和SKS波分裂观测数据,提供了对青藏高原岩石圈地幔实际变形方式的检验。这些新的数据不仅加强了高原内部力学耦合岩石圈的证据,而且也解释了高原外部相同的耦合特征。文中引入简单剪切变形和纯剪切变形的概念,用于解释高原内外不同的耦合变形特征。青藏高原和周围区域力学耦合岩石圈的垂直连贯变形有两个方面的大陆动力学含义:第一,岩石圈垂直强度剖面被一个重要的条件所约束,即要求与重力势能变化相关的应力能够从地壳传递到地幔;第二,青藏高原各向异性的空间变化反映了一个岩石圈变形的大尺度模式,以及从高原内部的简单剪切变形向高原外部的纯剪切变形的过渡带。文中提出的力学耦合岩石圈变形模型与当前已有的多种造山运动变形模型具有不同的变形含义,因此,地幔变形在青藏高原隆升过程中起主要作用。 | 王椿镛 常利军 苏伟 楼海 P.

| 13 | 分娩时有妊娠期高尿酸血症的先兆子痫患者早孕期的尿酸浓度显示文摘Objective: We investigated changes in serum uric acid across pregnancy in women with gestational hyperuricemia at delivery, with and without preeclampsia, compared with normal pregnant and women with preeclampsia without gestational hyperuricemia. Study design: This was a nested case-control study of 116 controls, 27 women with preeclampsia with predelivery hyperuricemia, 37 women with preeclampsia without predelivery hyperuricemia, and 35 women with gestational hypertension with hyperuricemia at delivery but without proteinuria. Serum uric acid and creatinine was measured across pregnancy. Results: Women with predelivery hyperuricemia,with andwithout preeclampsia, had increased uric acid concentrations across pregnancy compared with controls, after 25 weeks’gestation compared with women with preeclampsia without predelivery hyperuricemia. Adjusting for differences in glomerular filtration by serum creatinine accounted for part but not all of the increase in serum uric acid among women with preeclampsia and predelivery hyperuricemia. Conclusions: Among women with hyperuricemia at delivery, elevations in uric acid occur early. Multiple mechanisms may contribute to increased uric acid including changes in renal function. | Powers R.W. Bodnar L.M. Ness R.B. 李奎 | 2006 | 世界核心医学期刊文摘(妇产科学分册)2006,0,4: | 6 |
