In this paper, the generator model of constant transient voltage and the invariableness impedance model was used, and the saliency of generator is included; through the analysis of the characteristic of the network equation calculation in the transient stability analysis, a new node ordering algorithm is proposed. Better initial value can accelerate the convergence rate of the networking equations, reduce the number of iterations, thus to cut down the amount of calculating time.

本文首先建立了适合于暂态稳定分析的简单模型，其中发电机采用E_q恒定模型，考虑了发电机的暂态凸极效应，负荷采用恒定阻抗模型；研究了电力系统的暂态稳定分析方法，指出目前数值积分暂态稳定计算方法中存在的不足，主要是网络方程的求解速度过慢；分析了暂态稳定计算中网络方程的特点，将稀疏技术应用于网络方程的求解，提出了一种新的节点编号方法——最小度最小有源节点道路集算法，减少了网络方程的计算量；在进行交替迭代求解时，将预测算法应用于每一积分步网络方程功角和电压的初值估计当中，应用自回归算法和广义延拓算法，期望给出一个更有效的电压和功角初值方案，来加快方程的收敛过程，减少方程迭代的次数，以提高计算速度。

Therefore, it is more welcome to me than gold that Lesbia brings back my desirable.

感觉忽略西方的背景文化，很难理解到位，请高手继续，毕竟自己词汇量目前不足2K ，2K是这两天词汇突击时的认识。

So research in the cognitive diagnosis under polytomous scoring model is very meaningful.

随着布什总统&不让一个孩子落下&的政策出台，美国的认知诊断研究也逐渐成为热门，但目前的大部分研究仍基于0.1 评分，而多级评分可以提供更丰富的信息，并且我国的试题类型往往是多级评分的，因此研究基于多级评分的认知诊断具有重要的意义。1 本文采用模型介绍1.1 目前同类相关研究采用的模型及方法1.1.1 多级评分个人拟合统计量Drasgow提出的多级评分个人拟合统计量指标_l J可以将多级评分模型中被试是否属于异常反应诊断判别出来，但该指标功能局限性大，只能对被试反应模式是否正常做出定性说明，还不能指出哪些属性掌握与否，尚达不到针对考生不足之处进行补救教学的目的。1.1.2 Tatsuoka的规。。。。。。

Compared with the situation that other defends the virus method,this method has very good hiding amount of information,can take precautions against the executable file computer virus that has already known,ones that can be taken precautions against unknownly too and this kind of computer virus in the future.

分析了该方法的长处和不足，与其它防病毒方法相比，该方法具有很好的信息隐藏量，能防范已知的可执行文件类计算机病毒，也能防范未知的和未来的该类计算机病毒。

A certain micro space motor runs unstably in a high speed in space, especially when the lubricating oil is not full enough, the motor may even stops running; however, it will turn to be more stable while stopping.

某型号的航天微电机在太空中高速运行工作时转速不稳定，尤其在润滑油量不足的情况下甚至停机；而当要结束工作，缓慢停机时转速却变得很稳定。

In order to resolve the problems on model quality and data quantity in virtual city modeling, this paper discusses the 3D-model producing process including model-simplification process with modeling software such as 3DS MAX and MultiGen Creator. This processes is the foundation of romancing and roaming in virtual city on the Vage platform.

针对模型质量和数据量相矛盾的问题，分析了3DS MAX和MultiGen Creator各自的优点和不足，阐述了利用3DS MAX和MultiGen Creator相结合的模型构建方法，并以模型制作过程为例，探讨了两者相结合的一些关键技术，最后提出了一些亟待解决的问题。

If the cause is loss of volume, intravenous fluids should be supplemented; if vasodilatation (f. ex. due to large doses of epidural analgesia or habitual anti-hypertensive medication), the treatment is not fluid but is the dose adjustment of the provoking factor or vasoconstricting agents as e.g., Ephedrine.

如果低血压由液体不足引起，应增加静脉补液量；如果血管扩张（例如，因为大剂量硬膜外麻醉或习惯性的抗高血压治疗），则不需液体治疗而是调整扩血管药物的剂量，或使用血管收缩剂，比如麻黄碱。

If the fuel feed excessively are many, the spray hole blow atomizes not good, has blown late, the cylinder pressure low or the air supplies insufficiency and so on.

如供油量过多、喷油器喷油雾化不良、喷油过晚、气缸压力低或空气供给不足等。

This paper conducts comprehensive and in-depth research on the determination of unsaturated permeability coefficient and water-air flow during ponding infiltration by experiment research and theory research. The research is reduced as the following:(1) In this paper, in terms of the shortage of the current apparatus of water permeability for unsaturated soils, the new unsaturated steady seepage apparatus for measurements of unsaturated permeability coefficient has been developed based on improvement and amendment on original apparatus.

主要研究成果如下：(1)本文从非饱和土渗透特性研究的需要出发，针对目前研制的非饱和土渗透仪的不足，根据非饱和土稳态渗流试验装置量测非饱和渗透系数的主要特点及存在的问题，提出了新型非饱和土稳态渗流试验装置研制开发的整体思路，完成了重要内容的研制。

Another part of this study was to explore different pathways to make up for this problem.
