The granitic enclaves in the central-facies porphyroblastic lava are subvolcanic rocks with forming age of 134.2±1.9Ma. There is another intrusion of subvolcanic rhyodacitic porphyry with age of 136.0±2.6Ma, in the contact zone of the two volcanic cycles in the western part of the Xiangshan complex. The U-Pb ages of the sub-quartz-monzonite porphyry and lamprophyre are 129.5±2.0Ma and 125.1±3.1Ma, respectively. This suggests that the extension in the Xiangshan region, began in K〓, was week, and earlier than that in the coastal region of Zhejiang and Fujian provinces. Extension in K〓 in Xiangshan and neighboring regions was much stronger, forming NE striking large red-downfaulted-basins.

相山中心相碎斑熔岩中的花岗质包体属次火山岩，其成岩年龄为134.2±1.9Ma，在相山西部两火山旋回的界面之间，存在另一类次火山岩的侵位，其成岩年龄为136.0±2.6Ma，岩性为次流纹英安斑岩；次石英二长斑岩及煌斑岩的成岩年龄分别为129.5±2.0Ma及125.1±3.1Ma，说明相山地区的伸展、裂解作用明显早于浙、闽沿海，在K〓就开始了，但规模并不是很大；而K〓时期的拉张作用在相山及其邻区表现的更为强烈，形成了大面积的呈北东向展布的红色断陷盆地。

When sea level drops, forced by Kelioli, river mouth extends eastward and migrates southward, cutting down deeply. On the contrary, when sea level rises rapidly, river mouth jumps northward dramatically and moves westward, goes backward step by step. While sea level changes and river discharge is harmnize, as the geological depositional center is moving eastward and southward, driving by Keliolli and longshore drift, river mouth moves southward slowly, keeps relative stability, and forms the delta towards south slightly.

海面下降过程中，河流河口在科氏力作用下，南移东伸，下切迅速；反之，海面快速上升的过程中，河口则迅速北跳西移，逐步退缩；两者力量对比相当时，在沉降盆地沉降中心东移，并向南掀斜的背景下，在科氏力与沿岸流作用下，发育微微南偏的三角洲，河口缓慢南移，相对稳定。

Basing on the inspection , the study deems that Gendered Education has influenced deeply by Chinese traditional gender discourse which emphasizes gender differences.The educational tradition integrates the male and female simultaneously, but it was restrained by the fetter of Gender Essentialism.Gender-neutral Education is the production of education resulted from gender discourse of gender equality in modern China.The educational tradition has challenged Gender Essentialism in Gendered Education and endowed the male and female with the identical education right, but it actually has fallen into the Masculinism.

经考察，本文认为：性别化教育深受中国传统男女有别社会性别话语的作用与影响，这种教育传统虽将男女两种社会性别同时纳入教育系统，但受制于了性别本质主义的束缚；性别中立教育是现代中国男女平等社会性别话语作用于教育的产物，这一教育传统挑战了性别化教育传统中的性别本质主义，赋予了男女两性相同的教育权利，但却逐步陷入了男性中心主义。

In the article, we took part sample out of 158 patients to exam the expression level of Bcl-2 and Fas in myasthenic thymus tissue, and to find the role of which in whole pathogenesis. we also try to find the role of neopterin and sIL-2R through examing the concentration of neopterin and sIL-2R in peripheral blood of 26 MG patients. Material and methods1.select of case: to choose 158 patients who wear followed up from 1988 to 2002 after operation. All patients were diagnosed as MG, and treated with same medical cure during period of preoperation and post operation. 2.Collectionofdata:.To collect all data through designing a uniform follow-up table for thymectomized patients ,and to analysis the effect of factors including age, gender, disease duration of preoperation, clinic types and pathological types to prognosis at three follow-up period?

本文拟在对全组病例的远期预后进行流行病学统计分析的基础上，通过抽取一定量样本，研究重症肌无力患者胸腺组织中伽 12、Fas的异常表达及生发中心的形成在重症肌无力发病机制中可能的作用，以及它们对胸腺切除术后远期预后的影响；与之相似，通过检测部分样本外周血清中新碟吟和可溶性IL－2受体的浓度及其与正常对照组的差异，以期推测两者在重症肌无力起病及病情进展中的作用和意义，并分析其对胸腺切除术后远期预后的影响。

It is concluded that during the landfall of Saomai, the orographic uplifting is able to enlarge the rainfall of the typhoon, and also to enhance the centre potential vorticity, vertical velocity as well as the convergence of moisture flux obviously.

结果表明，台风登陆过程中地形抬升作用对台风降雨量有显著的增幅作用；台风中心位势涡度、气流垂直上升速度、水平水汽通量散度明显增大；地形抬升机制在台风登陆时刻达到最强。

It analyses the present situation of Chinese city security order supply and discusses the role of this theory. It is worth emphasizing that Polycentric Governance model is not really deny that necessity of country authority, on the contrary ,it requires that the country brings the broad effect into play completely.

值得强调的是，城市治安秩序的多中心供给理念，并不是彻底否定国家权威的必要性，相反，特殊的国情和特殊的时空条件都需要国家发挥广泛的作用；艰巨的历史使命和发展了的社会也对国家的质量提出了更高的要求，转型期的国家在许多方面还难以适应这些要求，因此市场和市民社会及时的起到了补充的作用。

Their main experience of tax paying service is as following: paying more attention on tax payers' rights, setting organization centered by tax paying service, launching various forms of tax propagand , decreasing tax payer's cost, and exerting effects of tax agencies, social organizations and high technology softwares.

国外纳税服务的先进经验主要是：税收服务强调保障纳税人的权利、以服务纳税人为中心设置机构、重视形式多样的税收宣传、努力按便利节省原则减轻纳税人遵从成本、充分发挥中介机构和社会力量作用、注重个性化的纳税服务、发挥技术载体在纳税服务中的应用作用。

At the same time, Beijings political and cultural functions were aggrandized too, and the integration of knowledge and economy made it became a new-economy center.

第四，城市地位、作用变化比较。作为20世纪以来城市发展动力机制与城市功能转变差异的结果，北京、上海城市地位与作用的变化可以被认为是20世纪北京、上海发展异同的最终体现。1 840年以前，北京位于中国封建城市体系的中心，而上海却位于这一体系的边缘，两城市地位的悬殊不可同日而语。

While the Economy is much more open capered to Germany, most of the exhibition companies are private companies, the exhibition centre are built by the governments and operated by private companies. The Governments are not always interfere with the industry affairs, are responsible only for transportation or some other public facilities and public administration.

而美国是开放的市场经济模式，在美国大多数的展览公司都是私人公司，展览中心有政府修建，但是运营都归私人公司管理；各展览公司与行业协会关系密切，在组织展览方面和组织观众方面充分发挥协会的重要作用；政府在会展运作中的管理作用不大，只负责交通等公共设施和公共管理，展览会的举办资格也不仅限为国有展览公司。

建构主义提倡在教师指导下的、以学生为中心的学习，也就是说，既强调学生的认知主体作用，又不忽视教师的指导作用。
