The sixteen plants are firstly divided into six types according to evaluation grades and subject function statistical method:the first type is Cajanus cajan and Crotalaria mucronata,the best adaptability ,which can be used pioneer plant or constructive species; the second type is Cynodon dactylon,the better adaptability, which can be used constructive species ;the third type is Eragrostis curvula, Paspalam notatum,which can be used constructive species on rotten rock slope ; the forth type is kummerowia striata,Lotus corniculatus and Vitex negundo.The adaptability is centered,and can be used protection species and auxiliary species;the fifth type is Robinia pseudoacacia,Eremochloa ophiuroides,Vitex negundo,Lespedeza formosa,Leucaena leucocephala,Desmodium sequax, Rhus chinne- nsis,which can't be plant singly and be used accessory species;the sixth is Trifolium repens,which can be used pioneer plant.

根据评价边坡防护植物适应性的十个重要指标，首次运用隶属函数和聚类分析方法，对各供试植物的边坡适应性综合排序并分为六类：第一类为木豆和猪屎豆，边坡适应性最强，适宜作为先锋植物和建群种；第二类为狗牙根，边坡适应性强，适宜与豆科植物混播，作为建群种；第三类为弯叶画眉草和百喜草，边坡适应性较强，适宜与豆科植物混播，作为风化岩边坡的建群种；第四类为鸡眼草、百脉根和马棘，边坡适应性中等，适宜作为保护种与伴生种；第五类为刺槐、假俭草、荆条、美丽胡枝子、银合欢、波叶山蚂蝗和盐肤木，边坡适应性较差，不宜单独在边坡上种植，最好与速生型豆科草本混播，作为边坡防护植物群落的辅助植物；第六类为白三叶，边坡适应性最差，但因其出苗率高、生长速度快，作为先锋植物，起到前期覆盖坡面的作用。

The modified double weight function method is to introduce new weight functions doing subtraction between two negative exponential-type functions.

The multi-wavelets functions are supported on [-1, 1], and one wavelet function is symmetric, the other is anti-symmetric.

所以，可以由这两个尺度函数构造一类多小波函数，这类多小波函数不但在[-1，1]上具有紧支撑性，而且一个小波函数具有对称性，另一个小波函数具有反对称性，因此这种紧支撑多小波函数适用于区间[0，1]。

This paper generalizes the conclusion of Perfect nonlinear S-boxes by Nyberg(1991), and introduces the conception of inverse regular generalized vector Bent function. It shows that for inverse regular generalized vector Bent function f with even variables, m is no more than half of?. It also shows that when the input dimension n is odd, the regular generalized vector Bent function and the inverse regular generalized vector Bent function do not exist. This may prevent the cryptology designer from seeking the inexistent function.

摘要该文完善并拓展了Nyberg(1991)的关于广义向量Bent函数性质的结论，相应于Nyberg给出的正则广义向量Bent函数，提出了&负则的广义向量Bent函数&的概念：得到有偶数个输入的负则的广义向量Bent函数输出维数也不大于输入维数的一半；证明了奇数个输入的正则和负则的广义向量Bent函数都不存在，这些结果的给出，可使密码设计者避免一味去寻找某类不存在的函数。
