The simulation analysis on seismic response of seven continuous rigid-framed bridges at the two states of SMA dampers control, restrainer control, was carried out. The results show that this kind of SMA damper can availably control the seismic displacement of bridge, whose control effect for expansion joint's displacement is better than steel restrainer.

6数值分析了某七跨连续预应力混凝土刚构桥在安装SMA阻尼器和传统钢棒限位器两种情况下的地震反应，数值结果表明：两者输出控制力相同的情况下，SMA阻尼器对梁体相对位移和关键部位位移的控制效果明显优于传统钢棒限位器。

Thirdly, we discussed how to decide whether the process is in control and if not, what shall we do to remove the signals. In this part, there are two aspects: T~2 statistic with unknown parameters and T~2 statistic with known parameters.

在此基础上，对如何通过历史数据建立稳态进行研究，其中的主要内容分为已知参数的情况下的异常值判异，未知参数情况下的异常值判异。

This article analyses the application conditions of freezing method, current research status and the problems in this field. It points that it's necessary to study deep freezing temperature field deeply and discusses the factors which influence the freezing wall such as soil's nature, moisture content, geological conditions, etc. It introduces the theory, process of freezing method, the distribution of temperature field of freezing method and key thermotics parameters influencing freezing temperature field. It simplifies the deep freezing temperature field model. Through ANSYS, this article founds the deep freezing temperature field model, and simulates the field on vary heat conductivities. It analyzes the results of ANSYS simulation, gains the theoretical value of thermometric holes which is needed by back-analysis. Using the simulation temperature and actual value, it gets the equivalent heat conductivity. Then it solves the deep freezing temperature field by the equivalent value, simulates the freezing wall development process and temperature change curve. Against the actual project, the results are favorable.

This paper will assume that there are effective stock market and effective executive market, and the basic hypothesises in Black-Scholes Stock Options Pricing Model are correct. We will discuss the optimal repricing scheme under three situations, one is that the board of the company considers repricing when the price declines straightly ; the second is at the beginning of stock life,the board promises to reprice under some conditions at a certain coming time; the third is when some condition happens at an uncertain coming time, the board promises to reprice the ESO.
