查询词典 error model

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.
