The paper founds GM(1, 1) model of gray prediction theory in order to predict level displacement,and forecast horizontal displacement of 8-8 section of the Olympic Games project with it and compares forecast data and actual data.The result is that GM(1, 1) model may forecast short-term horizontal displacement after the model is proved eligibility. In order to manage long-term horizontal displacement,the paper founds metabolism GM(1, 1) model.At first, founding GM(1,1) model with known data and forecast next numerical value,next renewing founded GM(1,1) model with numerical value at the same time abnegating first data,and then forecast nest numerical value with same method.

本文为了预测土钉支护水平位移，建立了GM(1，1)灰色系统理论预测模型，应用灰色预测法GM(1，1)模型对奥运工程地下通道I标段8-8剖面的土钉支护产生的水平位移进行了预测，并与实测值进行比较，得出灰色预测法模型经检验合格后可以对工程进行水平位移的短期预测；为了使GM(1，1)模型同样适用于长期预测，用新陈代谢的GM(1，1)模型，即根据己知数列来建立GM(1，1)模型，预测一个灰数值，然后不断地将预测值补充到己知数列之后，每补充一个再去掉一个最老的数据构成新的数列，建立一个新的GM(1，1)模型，预测下一个值。

The paper concludes with Section Five.A new algorithm is proposed in this paper.

The key of the simulation is to select a suited set of models and parameters which represent the motion and the echo of moving targets, Because the perform of microwave radars operating over the moving targets is very complicated.In this paper, we discuss how to simulate the motion of targets with a method of parameters simulation. And then we get a track clearly through controlling the flight parameters and the time increasing. The way reduces the error.This paper also particularizes the prime parameter of the echo--Radar Cross Section which is influenced by many factors.

对于目标的实时运动特性，本文采用了航迹的参数模拟法，通过控制目标的飞行性能参数与时间增量的大小来模拟目标的真实运动，避免了多种因素所引起的飞行误差，效果良好；此外，本文详细分析了表征运动目标回波特性的雷达截面积与雷达波长、目标姿态、极化方式及视角的关系，在此基础上，考虑了RCS的两种起伏特性以及天线对其的调制作用，得出了快、慢起伏目标回波的仿真数据，并对二者进行了比较。

After analyzing the impacting factors of natural vulnerability along the Pearl River mouth, the paper divides the coastline of approximately 412km into 25 15-minute gird cells. For assessment purposes, the six variables including geography, relative sea-level change, average tide range, regional slope, shoreline erosion or accretion rates and tropic cyclone impacting frequency are selected as assessed variables. Once each section of coastline is assigned a risk value for each specific data variable, the costal vulnerability index can be useto calculate the natural vulnerability of the areas along the Pearl River mouth. After that, the paper develops a database for assessment of coastal vulnerability to sea-level rises and protracts a 1:2,000,000 vectors CVI map of the coastlines along the Pearl River mouth.

为了探讨不同海岸带对未来海平面上升的自然脆弱性，本文以珠江口沿岸作为研究个案，在分析珠江口沿岸自然脆弱性的影响因子的基础上，把珠江口沿岸412km岸线划分为25个15′×15′的网格单元，选取了地质、海平面上升率、平均潮差、区域海岸坡度、海岸侵蚀/堆积率、热带气旋影响频率6个评价指标，应用CVI指数评价公式对珠江口地区进行海岸脆弱性评价，并建立海岸脆弱性评价数据库，绘制了珠江口沿岸1：2，000，000的数字化CVI图。

This paper research rimed turbine processing technology and the development of the domestic situation base on a vast amount of information in the literature, and then, research the basic principles and the processing characteristics and the processing technology of the EDMFor given the data of several-section of a blade, the wheel and the ring, this paper use UGNX to describe the precise geometric modeling of the rimed turbine.

本文针对给定叶片若干截面型值点数据、叶冠数据和轮毂数据的情况，利用UG NX对带冠扭叶片整体涡轮叶盘进行了精确的几何造型设计研究。

This paper examines the relationship between liquidity risk and stock return with the trade data of the A shares in ShangHai Stock Exchange and Shenzhen Stock Exchange.The method used in this paper is two-pass cross-section regression.After decomposing the liquidity risk into systematic liquidity risk and individual liquidity risk,we find that both risks have significant effect on the stock return.

0引言近些年由于长期资本公司的倒闭以及美国国债市场当中刚发行的国债比发行很久的国债(off-the-run)等资产定价异常现象的发现，越来越多的学者认识到流动性是金融资产一个非常重要的特性，流动性资产定价一直是近来金融研究的热点问题，把流动性引入到资产定价模型当中，可以更加全面、准确的对金融资产进行定价。

The following project stages came one after the other in a very uncomplicated and straightforward way: from the 1:10 section drawings, to the full-scale drawing made on spolvero paper (a type of pouncing/tracing paper).
