Through statistical analysis of more than1 0 0 times breakdown of cutting tools on the automatic machine tool,the checking and replacing model has been studied for cutting tool to machine only one part continuously.In this paper,by using of the D inspection method for the large- scale sample situation in the probability theory,it has been proved thatthe occurring law of cutting tool′s breakdown accords with the normal distribution.After figuring out the life- span distribution function of the system process,the multi- objective function equation has been obtained in which the unit expected loss of the qualified part is taken as objective and the checking interval as well as the regular replacement interval for cutting tool are variables.By means of enumeration and comparison methods to look for the solution on the microcomputer, the optimum checking interval and the optimum replacing strategy forthe cutting tool have been given which could bring outthe optimal economic profitin the system process.Since the occur- ring law of cutting tool′s breakdown accords the normal distribution,the improved model has been presented by adopting the regular unequal interval checking method and the better results than these of equal interval checking method are obtained. By using the algorithm mentioned above,the function has been solved fairly and the opti- mum solution has been got.In this paper two study cases are described.For case1 ,the inter- vals of replacing and checking are 369and 1 8respectively,the loss of unit qualified part is 4.61 5Yuan and it will be down to4.40 5Yuan if the unequal interval is adopted.For case2 , under complicated conditions,the intervals of replacing and thecking are30 6and2 8respective- ly,the loss of unit qualified part is 9.2 68Yuan and it will change to 9.0 4 7Yuan when using unequal interval.These results provide a more advantage proof for the improved model using the unequal interval checking method

An additive-dominant genetic model with genotype by environment interaction was employed to analyze the genetic behavior of flowering and fruiting at different development stages, with 2-year data from 4? diallel crosses. The results of variance analysis indicated that flowering and fruiting behaviors were mainly controlled by dominant effects at early period, but by additive effects later on. Compared with genetic main effects, GE interaction effects playeda minor role on the flowering and fruiting behavior. The analysis of covariance between average flower number, boll number at different development stages and total number of bolls showed that there were significant positive dominant correlation and negative or zero additive correlation before August lst, but having the opposite results afterward. Interaction correlation existed during the whole period. It was found, by further analysis of conditional variances, that different development stages have diverse gene action intensity. The last ten days of July and the first-middle ten days of August had the highest gene action level. Time interval of investigation played a great role on exploring the law of gene action during the flowering and fruiting period; when selecting the time interval of investigation, it is necessary to contemplate the purpose of the experiment, environmental condition, investigating traits and developing period simultaneously.

对4个陆地棉品种(系)双列杂交实验的2年观察资料按包括基因型×环境互作的加性-显性遗传模型进行不同发育阶段开花成铃规律的遗律的遗传分析。方差分析表明,开花成铃早期主要受显性效应控制,至中后期加性效应作用逐渐增强,基因型X环境互作效应相对较小,不同育阶段平均开花成铃数与总铃数的相关分析表明,8月1日前加性相关系数为负数或零值,但存在显著或极显著的显性正相关,8月1日后则相反。不同发育阶段平均开花成铃数的条件遗传分析发现:不同时期的基因活动强度不同,7月下旬及8月上中旬最大;检测间隔(t杒)对探讨花铃期基因活动规律有重要作用;选择调查周期时应兼顾实验目的、实验环境条件、入选性状及所处的发育阶段。
