grid interpolation meaning in Chinese
网格内插
Examples
- In this paper a new method of evaluating the efficiency of non - randomized artificial precipitation enhancement - cluster - analysis - based floating control historical regression method ( ca - fcm ) was presented , which made use of cluster analysis and grid interpolation of precipitation
本文利用聚类分析和雨量网格插值技术，对非随机区域历史回归试验进行了重要改进，提出了一种新的试验方案?基于聚类的浮动对比区历史回归人工增雨效果统计检验方法( ca - fcm ) 。 - Through the analysis of mapping relation between pixel point and a point of space , the paper pose a demarcate method based on grid interpolation . this method transform complicate nonlinear problem to many little regional linear problems and realize emendation on problems of linear and nonlinear deformation in image
通过对图象中的象素点与空间中的一点之间的映射关系的分析，提出了一种基于网格插值的标定方法，该方法将复杂的非线性的问题转化为一个个小区域的线性问题，实现了图象平面的线性和复杂非线性变形问题的校正。 - In the end , cluster - analysis - based floating control historical regression method with uniform precipitation and atmospheric precipitable water as metoorological covariates could more validly evaluate efficiency of cloud seeding operations and significant level of ca - fcm method was higher than the other methods , because it adopted cluster analysis which highly improved the correlativity between rainfall distributions in the control area and target area , and used grid interpolation which enhanced exactness of calculating precipitation rainfall , and chose atmospheric precipitable water as the covariant which increased the inferential accuracy of natural rainfall on the cloud seeding operational area
最后，得到以降水量和整层大气可降水量为协变量的ca - fcm方法，由于采用聚类分析( ca )方法，提高了对比区和影响区相关性；采用网格插值技术提高了雨量的计算准确度；引入了不受催化影响的物理协变量(整层大气可降水量) ，提高了作业区自然降水量估计值的准确性；所以评估效果最好，显著水平高于0 . 05 。
