变压器式可控电抗器的磁场和参数计算

采用场路耦合的有限元似稳电磁场分析方法,对只有一个控制绕组的变压器式可控电抗器在不同负载下的稳态磁场进行了分析,推导了磁场和参数的计算公式,确定了与控制绕组交链方向相反的两部分磁通的分界线位置,给出了解析计算参数与有限元数值分析结果的比较,说明两者具有很好的一致性.     

塔里木-中朝板块北缘的志留纪岛弧公婆泉群火山岩地质地球化学及构造意义

公婆泉群位于北山中部，可分为：北、南两带。南带为弧后盆地玄武岩-安山岩组合，北带为岛弧火山岩组合，西段窑洞努如为火山角砾岩和熔火山角砾岩组合，中段公婆泉一带为玄武岩-安山岩-流纹岩-粗面岩组合，东段东七一山地区为玄武岩-安山岩-流纹岩组合。岩石组合，地球化学综合分析认为，公婆泉群是中-晚志留世哈萨克斯坦板块俯冲与塔里木-中朝板块的产物。岛弧西段窑洞努如位于近大陆或者在水下陆壳。公婆泉位于近海沟陆壳，而东七一山则远离海沟，是在洋壳的基础上发育的。说明塔里木-中朝板块是一个统一的板块，同时在早古生代存在哈萨克斯坦板块向塔里木-中朝板块的俯冲。     

Advances in identification and application of tumor antigen inducing anti-cancer responses

Tumor antigen is one of the important bases of tumor immunotherapy . With the discovery of novel tumor antigens, interest in specific immunotherapy for treatment of malignancies has increased substantially. Nowadays more and more scientists paid close attention to various tumor antigens with their roles or/and applications in anti-cancer immune responses, immune tolerance, tumor markers,     

新课程下的数学教师培训

师资培训工作是课程改革实验工作的关键。其中，观念的转变是教师培训的核心内容，为了适应新课程，数学教师的数学观、数学学习观、数学教学观、数学评价观都需要做很大的调整。同时，数学教师的知识面和能力也需要拓广，促使教师改变的培训方式是多样的，案例加反思是具有代表性的一种方式。     

A UDDI Based Shared Resources Management Mechanism in Virtual Enetrprises .

Service and information resources are two kinds of major shared resources in virtual enterprises, where, service resources include third party‘s service resources and enterprise‘s legacy service resources, and information resources include database resources and file resources. Since service and information resources have distributed, autonomic, remotely bound as well as some other similar characteristics, an implementation mechanism on managing shared resources based on UDDI are presented. XML instances are used to describe resources authorization information, WSDLbased special XML instance represents information resource metadata, and these XML instancesare referenced by tModel for realizing the purpose of managing shared resources metadata based on UDDI.     

Contributions of different land cover types in Otindag Sandy Land and Bashang area of Hebei Province to the material source of sand stormy weather in Beijing

Different land cover types in Otindag Sandy Land and Bashang area of Hebei Province are linked to a material source of sand stormy weather in Beijing based on results of field vegetation and soil survey and laboratory works. Results of grain size analysis show that dust release potential in per unit area of moving sandy land is small,while lowland meadow and meadow steppe in stony hills have high potential of releasing dusts in per unit area during sand stormy weather occurrence. Further considering the effects of vegetation, it is inferred that the moving sandy land served as a material source of past dust storm and the possibility of dust release in per unit area is low in current time.Typical steppe in stony hills is undergoing desertification and its dust release possibility in per unit area is high. Farmland has strong potential of release dusts when they are ploughed in spring, but a large amount of therophytes grow and thus prevent dusts from release when cultivation was terminated.Potentials of dust release in per unit area in fixed sand dunes,stony mountain meadow steppe and low land meadow are lowdue to high cover of perennials. Sand dune reactivation and desiccation of lakes and lowlands under estimated future climatic change will make them serve as a future material source of sand stormy weather.     

纳米TiO2的制备及光催化性能

采用RF-PCVD法，以TiCl4 O2为反应体系，制备出了球状纳米级TiO2粉体。经TEM，XRD，BET测试表明，粉体为锐钛型金红石型的混晶体，粒径范围为20-60nm，平均粒径45nm。苯酚降解实验表明，TiO2粉体具有明显的光催化活性，并就光催化效率与德国产TiO2进行了比较。
