In this paper , we speed up lahe by presenting two slight modifications of the algorithm . firstly , in the computation of the local histogram , once a - by - square has been computed , the histogram for each successive square can be computed using only additions and subtractions 首先，在计算相关区域的直方图时，通过平移矩形区域减少了计算直方图所需的时间；其次，由于变换函数就是累积直方图，所以计算变换后的灰度时，利用对分的思想可以将效率进一步提高。
We obtained the uniform data distribution from discrete data points by inserting spatial dots and then set up digital elevation model ( dem ) of correlative area through constructing mutual linked triangle net . the isoline graph was implemented based on this model . during the processes , we combined the technology of stratification computing when inserting special dots in fault area with the technology of stratification triangle net in fault area for dealing with thrust data 然后介绍了在本研究中构造逆断层地质等值线的基本思路：从离散数据点结构出发，采用空间数据内插方法进行数据的均匀化，通过三角剖分构造出相互连接的三角形网络结构来建立起相关区域内的数字高程模型，利用该模型构造出相应的地质等值线图，其中使用扩展点与断层区的关系属性进行断层区分层空间插值计算处理和断层区域的分层三角形网格化处理相结合的技术，实现逆断层数据的处理和等值线绘制。
Numerical studies suggest that the wind stress over strong correlation areas which contributes to the interannual variance of sst is of little role on the development and maintenance of climatological state of the tropical pacific , instead of the wind stress over non - strong correlation areas 数值试验试验结果表明，强相关区域的风应力对形成和维持热带太平洋sst的气候场的作用不明显，而对sst的年际变率有重要贡献；相反，强相关区域以外的风应力对形成和维持热带太平洋sst的气候场起重要作用，但是对sst的年际变率所起的作用很不理想。
