During the course of the research , the criterions of the interpolation effect are mean error ( me ) , mean absolute error ( mae ) , root mean squared interpolation error ( rmse ) and the difference of mean square deviation between the measured and the estimated surface air temperature . the conclusions are as follows : ( 1 ) by contrasting the gaussian weighted model associated with the error modification with the gaussian weighted model , the error modification is proved to considerably ameliorate the precision of spatial interpolation ; ( 2 ) on the base of the gaussian weighted model , taking altitudinal effect into account can reflect the trend in which temperature changes according to the topographic altitude and may ameliorate the precision of spatial interpolation correspondingly and apparently , which indicates that topographical effect on the preciseness of spatial interpolation can not be disregarded in terms of the region with complicated topography ; ( 3 ) the map of daily surface air temperature distribution , using the modified gaussian weighted model a and b , can accurately reflect the temperature - changing - with - topographical - altitude trend . among them , the better is the model a , whose me is below 0 . 03 ? 在此过程中,采用平均误差( me ) ,平均绝对误差( mae ) ,插值平均误差平方的平方根( rootmeansquaredinterpolationerror ,简称rmsie ) ,插值前后测站要素值的均方差( meansquaredeviation ,简称msd )差值作为判定插值效果的标准,得出如下结论:通过高斯权重法与结合逐步订正的高斯权重法的对比,说明结合逐步订正方案的高斯权重法可大大提高地面日气温的插值精度;在高斯权重法中加入海拔影响项可以反映出温度随地形高度的变化趋势,同时也能较大地提高地面日气温的空间插值精度,说明在地形复杂的区域,地形影响在插值精度中是不可忽略的;对于高斯权重法的两种改进方案得到的地面日气温分布图都能很好地反映出表面大气气温随地形高度的变化趋势。
The aim of the paper is to research the system of mechanical drawing schoolwork correction according to the structure of the corrected parts , the schoolwork correction system can be divided into series of shaft - like , plate - like , fork - like and box - like subsystems a in the past several years , many difficulties of shaft - like correction subsystem had been solved so , this task is to find the common principle and process of the plate - like drawing correction system which is based on existent results , and this can help to the subsequent research on the plate - like drawing correction system according to the property of the errors , all drawing errors can been divided into absolute errors and comparative errors 按照批改零件的结构类型,机械制图作业批改系统可以分为轴套类、盘盖类、叉架类和箱体类一系列的子批改系统。经过几年的研究,轴套类作业批改系统的大量技术难题已经得到解决,并且提出了一系列重要的算法,现在已经能够正确批改一些轴类作业图。本课题的任务是继承已经取得的成果,探索盘盖类零件图作业批改系统的一般过程和规律,为盘盖类作业批改系统的后续研究作技术准备。
The expression between rms of slop error ( rmss ) and absolute error is educed according to boundary condition and the presumption that the curved surface is quadratic when the structure deforms and the aberration is symmetric . when rmsa keeps constant , rmss will decrease along with the increasing radial 假设薄膜结构在压力作用下,变形后的曲面为二次曲面,而且其变形是轴对称的,根据边界条件,推导出偏斜误差的均方根误差( rmss )与rmsa的关系式,得出当rmsa保持不变时, rmss会随着半径的增大而减小的结论。
