The relationship between minimal model characteristic value of electric power system tie flow Jacobin matrix and voltage steady-state stability is was discussed, and the minimal model eigenvalue is was defined as voltage stability abundant degree. On this foundation, the sensitivity of voltage stability abundant degree to control variables and to PQ point load are was defined in order to seek the factors of impacting voltage stability and explore the voltage weak point, and give out their algorithm simultaneously.

讨论了电力系统潮流雅可比矩阵最小模特征值与系统电压静态稳定性的关系，将最小模特征值定义为电压稳定裕度，在此基础上定义了电压稳定裕度对控制变量的灵敏度和PQ节点负荷灵敏度，用以找出对系统电压稳定性造成影响的因素和寻找系统电压薄弱点，同时给出了它们的算法。

Damon takes a trip to Georgia, where he surprises an old flame, Bree (guest star GINA TORRES - Standoff, Firefly, Alias, 24, Gossip Girl), and enlists her help to figure out how to open the tomb. In the process, Damon comes face to face with someone who is determined to make him pay for past wrongs. Stefan opens up to Grams (recurring guest star JASMINE GUY) in his effort to help Bonnie overcome her fears and accept her powers. While researching his history paper in the public library, Jeremy meets a cute but geeky girl named Anna (recurring guest star MALESE JOW - Unfabulous, Hannah Montana) who has her own theories on the folklore of Mystic Falls. When Damon returns from Georgia, Stefan is waiting with news that will change their world.

Damon去到乔治亚州，想给他的旧情人Bree (Gina Torres饰)一个惊喜，及请她协助，务求找出打开墓穴的方法，期间，Damon与一个决心要令他为过去的错误付出代价的人正面交锋；Stefan为了帮助Bonnie克服内心的恐惧和接受她自己的神奇力量，向Grams (Jasmine Guy饰)说出了真相；Jeremy在公共图书馆为历史研究论文做资料搜集时，遇上一个可爱但行为古怪的女子Anna (Malese Jow饰)，她对Mystic Falls的民间传说有自己的一套见解；Damon从乔治亚州回来时，Stefan正等待著他，要告诉他一个足以改变世界的消息。

Ask yourself these key questions to figure out what's wrong.

问一问自己这些关键问题来找出是什么出了错。

As the ego argues , by means of challenging questions , realize that to engage in trying to find answers to those challenging questions constitutes nothing more than a distraction from being on the Homing beacon ; that , in effect , the ego is being a kibitzer , and its motives—if , indeed , it could have real motives—do not involve your actually becoming clear .

小我总想藉由质疑的方式进行争辩，但你得了解，若你老想找出这些挑战性问题的答案，只会让自己偏离了家乡灯塔的指引；事实上，小我一直都是个好事者，老出馊主意，而它的动机（如果它真能有什么动机的话），絶不会是要让你真的搞清楚问题。

The origin of this thesis is a task from Shanghai Education Committee, which is to study the human factors in "evaluation of the safety techonology in shipping". Target for research is the seaman. The basic train of thoughts is as follows: Basing on the three steps i.e. the identification of risks, the evaluation of the risks and the proposals as the references for making decision, in safety system and employing the basic theory about human factors, the thesis identifies the main representations of the seaman's errors, analyzes the various factors influencing seaman's actions, evaluates the reliability of the seamen in both quality and quantity ways, finally finds out the foundamental causes leading to the seaman's errors and therefore offers the corresponding prevention measures.

本论文来源于上海市教委的课题"船舶运输安全评价技术"中关于人为因素的研究，研究的对象主要指海员，研究的基本思路为：基于安全系统工程中危险识别、风险评价和决策建议这三大基本步骤，运用人因基本理论，对海员失误的主要表现形式进行识别，分析影响海员行为的各种因素，定性和定量地评估海员的可靠性程度，并最终找出导致海员失误的根本原因，从而给出相应的预防措施。

In the study on the fern population structure, we through the analysis of the variation in height structure, leafstalk diameter structure and age structure in various forest communities, found the rule of variation of population, and discussed the reasons of variation of population structure, and explored the suitable habitat of various forest ferns.
