1. The main contents are as follows : 1 ) 3 eliminate error criterion method and step wise regression analysis method is used to analyze the errors of observation date . in the stepwise regression analysis , aging , loading and temperature which bulkily affects the dam ' s vertical deformation are selected as the regression factors , then regression equation and curve of each point are worked out
   运用3准则剔除误差法和逐步回归分析法对茅坪坝的观测资料进行误差分析，在逐步回归分析中，选用对坝体竖向变形影响较大的时效、施工加载和温度作为回归因子，求出各测点的回归方程和拟合曲线。
2. The main characteristics and advantages are : on one hand , we adopted the low - complexity bussgang algorithm , and did blind estimation to ofdm sub - channel according to the mean square error criterion ( mse ) and peak distortion criterion ; on the other hand , we used the differential detection , which accelerates the convergence speed and avoid the error transmission problem resulted from the bussgang algorithm
   这两种算法一方面采用了低复杂度的bussgang自适应算法，分别依据均方误差准则和峰值失真准则对ofdm系统子信道进行盲估计；另一方面通过引入差分检测技术，加快了算法收敛速度，克服了bussgang算法带来的误差传播问题。
3. Shiphandling simulator is a device that can partly imitate the true environment at sea ， and is specially designed to satisfy marine education and trains and maritime research etc . one of its key techniques is to create the virtual environment at sea ， and the terrain is its important component . according to the needs of the real time visual display of the shiphandling simulator ， this paper analyses the requirements of the geometry precision of the important islands and background hills which are within the ships ' visible scope ， and brings forward the modeling methods of the hill ' s pileup and the hill ' s silhouette edges based on contour lines . it also presents the definition of error that the hill ' s silhouette edges graph has been given and the effective scope of application ， and firstly established the error criterion of terrain model that is built in shiphandling simulator . with these two kinds of method ， the size of data storage can be minimized greatly ， and the requirements of high update rate and geometry precision for the real time visual display of the shiphandling simulator can be satisfied
   船舶操纵模拟器是一种能够部分模仿海上真实情况,专门为满足航海教育与培训、航海技术研究等目的而设计研制的装置，其核心技术之一是海上视景模拟，而地形地貌是海上视景中的重要组成部分.根据船舶操纵模拟器实时视景显示的需要，在分析航行船舶对可视范围内重要岛屿与背景山脉的几何精度要求的基础上，提出了基于等高线的山形堆积建模和山形轮廓建模方法，并给出了山形轮廓图形的误差定义、有效适用范围，以及船舶操纵模拟器中地形建模的误差准则，该方法生成图形的数据量较小，其图形更新速率与几何精度能达到船舶操纵模拟器实时视景显示的要求
