First,the distance ratio between within-class and between-class of each column of mixing matrix is computed by using a distance measurement.Then,for each class,the mixing matrix and independent components are re aligned by sort ascending according to the distance rate,and the columns of the weight matrix with smaller distance ratio and the corresponding features are reserved.Finally,the best feature set is selected by genetic algorithm from these foregoing feature vectors.

Firstly, the eigenvalue problem of a class of second order elliptic equation with critical potential and indefinite weights is considered. Then, using critical point theory, Trudinger-Moser inequality and the properties of the first eigenvalue, we prove the existence of a nontrivial solution for a class of nonlinear elliptic with critical potentialand indefinite weights in R~2. Secondly, we prove the existence of nontrivial solutions for a class of subcritical and critical elliptic systems with indefinite part in R~2 byusing a generalized linking theorem, Trudinger-Moser inequality and concentration-compactness principle.5. The existence of at least three weak solutions for discrete boundary value problem is established by using a three critical point theorem introduced by Ricceri.

首先，讨论了R~2中一类带不定权且含临界位势的二阶椭圆型方程的特征值问题，并借此特征值问题的第一特征值性质，利用山路引理及Trudinger-Moser不等式，证明了R~2中一类带不定权且含临界位势的非线性椭圆型方程非平凡解的存在性；其次，利用广义环绕定理，Trudinger-Moser不等式及集中列紧原理，得到了R~2上一类具有强不定部分的半线性椭圆型方程组在非线性项分别为次临界增长和临界增长情形下非平凡解的存在性。

Computation makes clear as a result, the smooth balance of power that 6 ammonia in 6 ammonia magnesium chloride form in nucleus and other electron breaks up in field, cent is two class, the first class 4 ammonia, the 2nd class 2 ammonia, when outside ambient changes, it is to shuck off 4 ammonia element likely most, additionally 2 ammonia are shucked off again after warming up, this one conclusion accords with experimental result to agree.

计算结果表明，六氨氯化镁中的6个氨在原子核和其它电子形成的平均势场中分裂，分为两级，第一级4个氨，第二级2个氨，当外界条件变化时，最有可能是脱去4个氨分子，升温后再脱去另外2个氨，这一结论符合实验结果一致。
