CHEN Nan~(1) WANG Qinmin~(1) Tang Guoan~(2) ZHAO Yuanwei~(3)(1 Spatial Information Research Center,Key Lab for Data Mining and Information Sharing of Ministry,Fuzhou University,523 Gongye Road,Fuzhou 350003,China;2 Key Lab for the Science of Geography Information of Jiangsu Province,Nanjing Normal University,122 Ninghai Road,Nanjing 210097,China;3 Baqiao Branch of Xi'an Environment Protection Bureau,87 Xinyi Road,Xi'an 710038,China)  
The researchers analyze the slopes derived by different algorithms and conclude that the reasonable algorithms are those of three-order inverse distance square weight difference and three-order inverse distance weight difference.
