静电纺丝法制备SnO2多孔纳米管及其光催化性能研究

通过静电纺丝法制备了一种氧化锡一维多孔纳米管材料，获得的光催化剂用X射线衍射（XRD）、扫描电子显微镜(SEM)和紫外-可见（UV-Vis）漫反射光谱表征，所制备的氧化锡多孔结构纳米管光催化剂表现出紫外光下（λ＜ 400 nm）增强光催化降解甲基橙的性能，光催化活性的增强是因为其巨大的比表面积和较小的晶粒尺寸.这一方法可以用于制备其他类型的一维多孔纳米管材料.

Partial strikes under the railway labor act: The need for a doctrine of unprotected concerted activity

In light of use by airline unions of partial-strike tactics, such as concerted refusals to bid for overtime work and so-called ” CHAOS” tactics involving unannounced refusals to fly after passengers have been ticketed and are ready to board, the authors examine whether the Railway Labor Act (RLA) should be interpreted to permit employers to discipline employees for engaging in such tactics, or whether these are a protected form of economic pressure. Although in many respects bargaining duties and economic weapons under the RLA are read consonant with precedents under the National Labor Relations Act (NLRA) (which governs all industries other than rail and air transport), there are a few decisions suggesting that during the period when self-help may be resorted to, employees can engage in partial strike activities as long as they violate no court order but are subject to permanent replacement in limited circumstances. These decisions, the authors submit, fail to take account of Supreme Court decsions since the 1930s that some economic pressures by unions, such as slowdowns and sitins, may not violate the labor laws but nor are they protected by those laws so as to immunize partial strikers from employer discipline. These decisions are not based on unique features of the NLRA. Rather, they give recognition to the background assumptions of Congress that employers may act to protect their property interests as long as they do not run afoul of NLRA or RLA protections and that employees who engage in partial-strike activities are subject to employer discipline even where not strictly necessary to maintain operations. Moreover, these tactics skew the bargaining process by giving employees an essentially risk-free gambit to pressure their economic position through planned disruption of carrier operations.

谎言与目的原则﹑合作原则及礼貌原则

谎言是常见的语言现象,合作原则和礼貌原则对谎言现象有一定的解释力,然对曹禺戏剧<日出>中谎言现象的分析发现:本文拟提出的目的原则(Intention Principle,简称IP)对戏剧中的谎言现象具有相当的解释力,可作为对合作原则(Cooperative Principle,简称 CP),和礼貌原则(Polite Principle,简称PP)在解释某些语言现象,如谎言现象方面起到补充作用.     

串联稳压器基准误差放大电路的设计

针对串联型稳压器,设计了一种应用于串联型稳压器具有自建基准的新型误差放大电路。该电路具有构思巧妙,结构优化,易于集成及较高的开环增益,共模抑制比及交流特性的优点。通过验证,实测数据与仿真结果基本一致。     

论正当防卫的限度

正当防卫的限度是在法学理论学界和司法实践中均有争议的问题 ,本文主要以 1997年《中华人民共和国刑法》关于正当防卫的规定来研究正当防卫的限度及特殊防卫权。这对如何认定特殊防卫权具有重要意义。
