抑制直流偏磁电阻的全网优化计算
Global Network Optimized Resistance to Restrict Transformers Direct Current Magnetic Bias
 [PDF]


Advances in Energy and Power Engineering (AEPE) , 2013, DOI: 10.12677/AEPE.2013.12015
Abstract:
当高压直流输电系统双极电流不对称或单极大地回路运行时,巨大的接地极电流入地会使接地极附近变电站的变压器产生直流偏磁,对交流系统造成不利影响。中性点串接电阻是抑制直流偏磁的有效方法。本文基于增量网络的灵敏度分析方法,以变压器中性点电流极限值为约束条件,提出了全网优化接地电阻的计算方法。以天广直流输电线路北郊附近的变压器仿真表明,这是一种简单有效的抑制全网变压器直流偏磁电流的方法。全局优化接地电阻的计算方法可以为实际工程提供参考价值。
When bipolar current of high voltage direct current transmission system operating asymmetrically or monopolar-ground return operating, huge direct current will pour into the ground through the earthing electrode and thus, transformers nearby will be influenced by direct current magnetic bias and add harm on alternating system. Installing resistance in serial of neutral grounding transformers is an effective method to restrict transformers direct current magnetic bias. The paper presents an optimized configuration method of ground resistance to make all the currents through the transformer neutral point in the grid within its limits on the basis of increment network sensitivity analysis. The proposed method is verified by the data from tian-guang HVDC, and the verification result shows that it is a simple and effective method of restricting all the neutral direct current magnetic bias by optimized resistance. The global network optimized resistance method can provide reference value for practical project.

The conclusion of significant gender differences in university students in somatization, compulsion, depression, anxiety, terror, paranoia, and psycho has come out while the cause is analyzed, pointing out that university counselors should pay more attention to female college students in order to achieve the goal of “gender education”. This indicates the direction of psychological health education for university students in the future.


关于生物能量传递、补偿等几个问题的思考

 [PDF]

Abstract:
本文通过若干生物学现象,对“生物能量传递、补偿”等问题得出如下认识:(1) 生物在进行某一器官分化前,需要某种特定能级的能量去启动特定的基因。(2) 所有生物在完成每个生育阶段时,都需要多种能量,且要求每种能量的数量都有一个临界值;在临界值以上,各种能量可以相互转化和补偿,但这些能量之和是一定的。(3) 能量在生物体内可以直接传递,但以间接传递为主要方式。
This paper, through some biological phenomena, comes to a conclusion on the issue of “biologic energy transfer, compensation”: (1) In a biological organ differentiation, a certain level of energy to activate specific genes was required. (2) At the end of each growth stage of all organisms, many kinds of energy were needed, and the number of each type of energy has a critical value; above the critical value, all kinds of energy can be transformed into and compensated each other, but the sum of the energy is certain. (3) Transmission of biologic energy included direct and indirect transmissions, but the indirect transmission was the main way.

SGP的力学性能研究综述
Review on Studies on Mechanical Properties of SGP
 [PDF]

Abstract:
聚乙烯醇缩丁醛中间膜(PVB)在过去几十年被广泛应用于夹层玻璃中。如今新型的离子性中间膜(SGP)较之PVB具有更好的强度和刚度,SGP的采用使得夹层玻璃从之前的仅仅作为安全玻璃发展为结构的一部分。基于其良好的力学性能,SGP在幕墙结构中得到越来越广泛的应用,特别是一些超高层和大型城市公共建筑。然而,到目前为止,对SGP的力学性能尚未有系统的研究,这对夹层玻璃的设计造成了一定困难。本文主要介绍了国内外关于SGP力学性能的研究现状,并根据试验目的和方法的不同进行了归纳总结。
Polyvinyl butyral (PVB) has been widely adopted for interlayer in laminated glass in the past dec-ades. Nowadays, a new interlayer SentryGlas?Plus (SGP) has been developed, which has better stiffness and strength compared with PVB. SGP’s application makes laminated glass not only to be shatterproof glass, but to be a part of the structure. Due to its superior mechanical properties, SGP gains more and more application in curtain wall structures, especially in super high-rise buildings and large-scale public buildings. Nevertheless, there is no systematic study on SGP’s mechanical property, which causes some difficulties in the design of laminated glass. This paper reviews the present researches on mechanical performance of the SGP around the world.

On this basis, the framework and database organization of the information system of managing land surveying and mapping with C/S structure were designed. This paper developed the information system of managing land surveying and mapping, which synthesized the project management, da-tabase management, process management and application tools, based on the Oracle 10g Standard Edition database platform as well as ArcEngine and ArcSDE geographic information platform by adopting Visual Studio2008. The system achieved good results through actual application.
北半球冬季准定常行星波传播的年代际变化

自然科学进展 , 2006,
Abstract: 通过利用NCEPNCAR再分析资料对1958—2004年共46个冬季北半球大气准定常行星波传播的年代际变化进行分析,发现气候态意义下的准定常行星波沿高纬度由对流层向平流层的传播和在对流层内向低纬度的传播之间存在显著的反相振荡关系. 进一步的研究还表明,准定常行星波传播的年代际变化与北极涛动有密切的联系;北极涛动的正位相对应于在对流层有异常强的从中高纬度向低纬度对流层顶附近的波动传播,同时通过极地波导向平流层的传播明显减弱.其结果不仅说明大气内部的准定常行星波与纬向平均流相互作用可以产生年代际尺度的变化;而且提供了平流层变化影响对流层大气环流长期变化的一种动力学机制.
