METHODS: By cluster sampling, 214 cadets from a military academy were investigated with Modified Big Five Personality Scale and selfdesigned decisionmaking scale. The cadets were randomly divided into 2 groups. After noneffective questionnaires were eliminated, the first group (n=110) were in a positive framing and the second group (n=104) in a negative framing. A chisquare test was used to analyze the results of program chosen and t test was used to determine the relationship between personality dimension and risky choice.

Results: Before intervention, the total scores, A (antisocial/disobey behavior) and N scores of the Ratter Parent Scale were of no difference. After intervention, the total subtraction scores (4.10±3.21), A subtraction scores (1.10±1.37) and N subtraction scores (1.32±0.91) in the intervention group improved significantly (P.05 -0.001), the recovery rate by clinical evaluation was 34%.

结果：干预后，比较两组Rutter儿童行为父母问卷的减分值，干预组总分减分(4.10±3.21)、A分减分(1.10±1.37)和N分减分(l.32±0.91)与对照组总分减分(l29±3.15)、A分减分(0.53±117)和N分减分(071±110)相比差异有统计学意义（均为P.05），干预组有34%的儿童恢复正常。

First,the determinant is regarded as a function of or- der n and denoted by D;Second,the determinant is expanded by row or by column,then the relation in both of Dand subdeterminants will be examined in details to set up certain a recursion,generally speaking,it must be a homogenous or a non homogenous recursion;fi- nally the coefficients of the general solution are found out with the aid.

给出了用递归关系方法求任意 n 阶行列式的值的一般方法：首先，把已知的 n 阶行列式看作为阶数 n 的一个函数，记为 D；其次，按行或按列展开这个行列式，并仔细观察存在于余子式及 D里的关系，建立关于 D的某一递归关系，此关系总为一个齐次的或非齐次的递归关系；最后，借助于 D(0)、D(1)和D(2)等求出递归关系的通解的系数。
