暂时过电压对SPD后备保护的影响

施加给电气装置的电压如超过电气装置的标准电压,称作过电压。低压电气装置可能出现各种过电压,例如由于电网和电气装置运行条件的变化引起工频电源电压变化而出现缓慢而持续的线间过电压。本文分析了低压系统暂时过电压形成原因,并给出了不同供电制式下的最大暂时过电压值。探讨了暂时过电压对SPD的影响及SPD后备保护需要注意的问题。

燃料气压缩机在低气量和压力下运行的研究和应用

主要介绍了燃料气压缩机是为燃气轮机提供一定压力和温度的燃料气的动力设备。时常由于作为临时原料气的燃料气入口压力低造成燃料气压缩机由于排气高温而停机。这时燃机也因为缺乏燃料而停机。通过采用两台燃料气压缩机串机运行、并机运行和单独运行时打开补气阀补气的措施，最终解决了燃机的供气问题。     

Researching Projects and Theorizing Families of Temporary Organizations

Following contemporary development in which most temporary, focused, and organized endeavors can be regarded as a project and studied as a temporary organization, here we ask: How can these phenomena be defined without hindering pluralism in understanding, development, and theorizing? Based on the notions of family resemblance—the idea that it is not a specific trait, but a variety of traits that are shared by some, but not all, members of a family—we propose a new dynamic framework we believe is useful in advancing the studies of projects and temporary organizations toward more opportunities for rigorous theorizing.     

双承台超宽悬臂梁0#块支架施工技术

某高速公路高架桥跨越河流部分为单箱三室结构悬臂箱梁,半幅设分离双柱式矩形墩柱,利用既有的承台,采用钢管及悬挑支架的方式,实现了0#块浇筑施工。该方案具有工期较短、承载力好,安全系数高,同时作为悬臂梁的临时固结,为同类桥梁临时支墩设计施工提供参考。

Optimal Accounting Method of Income Taxes for Chinese Enterprises under New Environment

Due to the strengthening principle-based accounting system by Chinese government, the rapid development of business merges and re-organizations, and accounting revisions aiming to restrict accounting frauds, the temporary differences of income taxes are increasing greatly and showing many varieties. This paper examines advantages of the tax consequence method, especially the balance sheet liability method, in dealing with temporary differences of income taxes over the tax payable method. These advantages are quite significant in aspects of accounting aims and information relevancy. By taking certain measures to improve the reliability of information and reduce its applying cost, the balance sheet liability method is shown to be an optimal accounting choice for Chinese enterprises.     

对物流仲裁规则问题的探讨

物流仲裁规则中有关受案范围的表述方式应当采用概括式,简明扼要地表述为受理一切有关物流纠纷的事宜,包括合同和非合同纠纷。临时仲裁应引入物流仲裁机构的物流仲裁规则中，使当事人选择了仲裁机构后可以适用临时仲裁方式。为避免不当的仲裁裁决，应当给予当事人申诉的权利,实行物流仲裁一裁终局与申诉相结合的最佳方式。
