  1. However we want to get the least absolute value of frequency deviation not the least square sum of it

    但是實際需要的是使頻率偏差的絕對值最小而不是頻率偏差的平方和最小。
  2. The paper studies composition of grasshopper community in different habitats, found that differences in family, genus and species and analyzed the causes of those. the author analyzed the following aspects by spss software and the measure of euclidean distance : ( 1 ) analyzed the relationship between grasshopper species and geographical distribution and divided 9 forestry belt into 3 main habitat model : low mountain conifer and broadleaf integrated forestry belt ; low mountain chanbai conifer forestry belt and middle - high conifer - betula ermam / - tundra belt ; adopted sum of deviation of square to clustered ecological species groups, and thus divided 48 grasshopper species into 3 main category, 12 ecological species groups

    在長白山地區蝗蟲生態分佈特點的研究中，主要應用spss軟體包、採用euclideandistance測度法對以下兩方面內容進行了分析： （ 1 ）對長白山地區蝗蟲地理分佈關系進行了分析，將長白山9個林帶劃分為三大生境型：低山針闊葉混交林帶、低山長白松林帶和中高山針葉?岳樺?苔原復合體； （ 2 ）利用離差平方和法對生態種組進行等級聚類，結合實地調查結果，將48種蝗蟲劃分為三大類12個生態種組。
  3. Now the common algorithm which is used to calculate the parameter of the compensation network is the method of least squares which can calculate the result to make the least square sum of frequency deviation least

    目前國內外計算補償網路參數的常用演算法是最小二乘法，最小二乘法能夠求取使得使頻率偏差平方和最小的值。
