目前机械加工企业根据国际标准偏差加工工件,由于受操作者主观因素的影响,工艺能力下降,工程等级降低,不能满足产品质量的要求,而配合尺寸公差中心范围加工法则很好地解决了这一问题。笔者论述了机为加工的质量特征分析,通过实例论证了配合尺寸公差中心范围加工法与传统加工方法的优越性与可行性。  相似文献

汉文帝刘恒在位23年,他对诸侯王优容有加,主要有汉初的社会经济和他本人的个性特点两大方面的原因。也就是说,汉文帝即位初期的政治经济背景以及汉文帝本人的个性特点造成了他对诸侯王的优容甚至纵容,使得诸侯实力得以逐渐增强,终于威胁到中央集权。  相似文献

A conformance proportion is an important and useful index to assess industrial quality improvement. Statistical confidence limits for a conformance proportion are usually required not only to perform statistical significance tests, but also to provide useful information for determining practical significance. In this article, we propose approaches for constructing statistical confidence limits for a conformance proportion of multiple quality characteristics. Under the assumption that the variables of interest are distributed with a multivariate normal distribution, we develop an approach based on the concept of a fiducial generalized pivotal quantity (FGPQ). Without any distribution assumption on the variables, we apply some confidence interval construction methods for the conformance proportion by treating it as the probability of a success in a binomial distribution. The performance of the proposed methods is evaluated through detailed simulation studies. The results reveal that the simulated coverage probability (cp) for the FGPQ-based method is generally larger than the claimed value. On the other hand, one of the binomial distribution-based methods, that is, the standard method suggested in classical textbooks, appears to have smaller simulated cps than the nominal level. Two alternatives to the standard method are found to maintain their simulated cps sufficiently close to the claimed level, and hence their performances are judged to be satisfactory. In addition, three examples are given to illustrate the application of the proposed methods.  相似文献

In this paper, inference for the scale parameter of lifetime distribution of a k-unit parallel system is provided. Lifetime distribution of each unit of the system is assumed to be a member of a scale family of distributions. Maximum likelihood estimator (MLE) and confidence intervals for the scale parameter based on progressively Type-II censored sample are obtained. A β-expectation tolerance interval for the lifetime of the system is obtained. As a member of the scale family, half-logistic distribution is considered and the performance of the MLE, confidence intervals and tolerance intervals are studied using simulation.  相似文献

This study investigated the extent to which tolerance of uncertainty affects the relationship between happenstance skills and career satisfaction via career decision self‐efficacy. Moderated mediation analysis was conducted on data collected from 321 graduates (175 men, 146 women) of Korean universities making the school‐to‐work transition. Results showed that career decision self‐efficacy fully mediated the relationship between happenstance skills and career satisfaction. Furthermore, the moderation effect of tolerance of uncertainty had a significant impact on the relationship between happenstance skills and career decision self‐efficacy. Tolerance of uncertainty should be considered an important variable in happenstance career theory and intervention. Unplanned influences should also be considered important factors in the career decision‐making process.  相似文献

This paper addresses the poverty of services available to lesbian victims of partner abuse, despite the need for such services. Drawing on data from a survey of 1,505 help providers (to which 566 responded), the paper focuses on the services that the help providers themselves claim to offer. The data reveal a serious disparity in help providers' rhetoric and offical policies and the reality of the services available. The paper concludes with suggestions for improving services to battered lesbians.  相似文献

程序上起诉机关对持有型犯罪主观罪过举证责任的免除并不意味着实体上主观罪过不再是该类犯罪的构成要件。坚持罪过责任原则,必须承认主观罪过是持有型犯罪的主观构成要件,其最大的意义在于被告人可以此进行无罪辩护。该类犯罪的主观罪过既可以由直接故意构成,也可以由间接故意构成。  相似文献
