On the change period from medico to medical, stronger general education is very important to cultivate ethic and ethics, society liability and occupation custom of medical practice students.

随着社会对医学人才要求不断的变化和提高，现代医学人才必须兼具科学精神和人文精神，作从医学生到医生转变阶段的实习阶段是两精神从理论到实践的转化阶段，这阶段强化通识教育对培养未来医务工作者所需的伦理道德、职业习惯、社会责任感等人文素养的形成具有重要的意义，同时这一时期也是医学生专业科学精神和创新思维的起始阶段，这一时期强化通识教育是十分必要的

When there is no trailing of the minor planet image (or you are measuring the middle of a trail) the time of observation is the mid-exposure time. If you are measuring both ends of a trail, then one end is associated with the start of the exposure, the other with the end.

如果你测量的是小行星拖线的中部或该小行星没有明显的拖线，那么你应该使用你暴光时间的中点时刻作为该测量点对应时刻，如果你既测量了起点又测量了终点，那么你应该分别对应的是暴光的起始时间和终了时间。

In the course of it the reader is reminded that as the "Mother of Parliaments" Britain was far from first in the field (Iceland's Althing met much earlier), and that habeas corpus, that cornerstone of British liberty, passed on to the statute book in 1679 through a deliberate miscount in the House of Lords, Mr Kellner has explained.

在阅读此书的过程中，作者提醒读者：号称"议会制度的发源地"的英国事实上并非如此（冰岛的两院制议会起始时间早很多），柯尔尼先生又解释道，人身保护令、英国自由权的基石，都是由于在1679年上议院投票时故意点错票数通过并写进法令全书的。

Several studies have indicated that SuSy performed a very important role during the fiber initiation and elongation. Furthermore, down-regulation of SuSy mRNA levels in the cotton ovular epidermis by RNAi leads a fiber-less phenotype.Efforts to understand and manipulate fiber development would be enhanced by an improved knowledge of the promoter elements and transcription factors that regulate fiber relative gene expression.

研究者发现SuSy促进棉纤维细胞的分化与伸长，同时SuSy在棉纤维细胞的起始和伸长等一系列活动中起着至关重要的作用，以RNA干扰的方式抑制该基因的表达后会使转基因棉花出现无毛的表型。

Cloning and sequencing of the genes coding a and 3 subunit of phycoerythrin of a red alga-Corallina officinalis are reported firstly(GenBankaccession number: AF510986). The sequence contain 1,140 nucleotide, including 10 nucleotide that locate in the upstream of the initiation codon ofP subunit, 534 coding for P subunit(coding 177 amino acid), 101 nucleotide for gene spacer and 495 nucleotide that draw near the 5 terminal of a subunit(coding 164 amino acid).

首次测定了珊瑚藻藻红蛋白α和β亚基基因的全序列(GenBank登录号：AF510986)，测定的基因序列长为1，140个碱基，包括β亚基起始密码子上游的10个碱基，6亚基编码区的534个碱基(编码177个氨基酸)，101个碱基的间隔区以及α亚基编码区近5'端的495个碱基(编码164个氨基酸)。

At the same time, other research on the followings: how to choose a proper replace project plane, discussing replace region, making out reference ellipsoid parameters, transferring the geodetic coordinate system to the regional coordinate system, seeking for the proper way to choose coordinate system.According to the research on the second degree GPS control nets of WeiHai, a fully and systemic account is generated from layout、 choosing a coordinate system and checking the original datum to the objection and adjustment computation.

本文通过对威海市城市二等GPS控制网的研究，从设计、选择坐标系统、起始数据检验、到观测、平差计算等工序作了系统的论述；通过威海城市二等GPS控制网高程拟合问题的讨论，研究高程拟合的适用范围，选择合适的高程异常已知点，尤其对于高程异常变化剧烈的山区，高程拟合的精度问题进行了研究。

The suitable synthesis conditions were defined as follows: the molar ratio of DCPP and resorcin was 2.1:1;the dosage of catalyst made by myself was 1.5% of the amount of the resorcinol;the first reaction temperature was 120～130℃,the reaction time was about 60min,the second reaction temperature was160～170℃,the reaction time was 60min,the third reaction temperature reaches to 210～220℃ for removing the unreacted phenol and superfluous DCPP.

确定了反应的最佳工艺条件：DCPP和间苯二酚的物质的量之比为2.1：1；使用自制的催化剂，用量为间苯二酚质量的1.5％；起始反应温度为120～130℃，反应时间约为1h；第二步反应温度为160～170℃，反应时间约为1h，最后把温度升到210～220℃除去残留在产品中的苯酚和过量的DCPP，产品收率约为92.0％。

The synthesis of the pentacyclic skeleton of Et-743 and the construction of the five chiral centers thereof.1. The core pentacyclic skeleton of phthalascidin was constructed with L-dopa as the starting material via thirteen steps. First, two basic synthons, the C-1 functionalized tetrahydroisoquinoline compounds 8 and N-protected Z-dopa derivative 9, were prepared from L-dopa. They were coupled via amide bond to form the dipeptide compounds 10, which were the first key intermediates. Then the primary hydroxyl groups were transformed into the corresponding amino aldehydes 11 via Swern oxidation. Followed by the intramolecular Pictet-Spengler cyclization, the pentacyclic compounds 12 were synthesized.

五环骨架的构建及五个正确手性中心的确立：1.1我们以L-多巴为起始原料，经过多步官能团保护和转化合成了基本结构单元8然后和苯丙氨酸衍生物9，通过缩合反应生成酰胺中间体10，经Swern氧化得到醛化合物11，然后再次利用分子内改良的Pictet-Spengler反应一步构建c，d两环，得到五环骨架化合物12，最后，实现了21-位羰基向氰基的转化，得到了C-1位官能化的化合物14，化合物14不但具有和Et-743一致的五环骨架，而且分子中五个手性中心立体构型也与其完全相同：其中，3，位和13，位的手性中心由原料L-多巴带入，而1，位，11，位和21，位手性中心则通过不对称诱导而确立。

The show is divided into sections, starting with some of Cartier-Bresson's most arresting surrealist work from the 1930s, such as a sunbather in Trieste, Italy, whose white body echoes a sliver of white in the grass, and his self-assured prostitutes in Mexico City.

展会划分为几个部分，起始部分是布勒松自19世纪30年代以来拍摄的最受人瞩目的超现实主义作品，如摄于意大利里亚斯特城的日光浴者，其白皙的身体仿佛草丛上一抹白色的裂痕，又如摄于墨西哥城的一个自信的妓女。
