The payoffs of games depend on parity of starting capital. Only when p2 is equal to p3, both of them are less than 0.5, payoffs of games do not depend on starting capital. Furthermore, when p3＝0.5 playing game A and B in alternating order must be a losing game. What is more, the condition of parity of starting capital in computer simulation corresponds to minimum and maximum stationary distribution probability of theoretical analysis respectively in its feasible region.

And has done the tired life test of the hypoid gear. As the samples of the test data of gear life test is very few, the author has made the error model of tes tinghypotheses when using k-s method, the auther presented a testing hypotheses method which can make use of the information of the samples and reduce the error of probability Calculation. It is Called"the improved K-s method". The author has used this method to deal witch the life test datas and the result is identical with the result of the theoretical calculation.
