8楼：RE：来这里的有几个是6西格玛黑带大师？

So what are the seven deadly sins of Six Sigma or in other words, what should you avoid if you are looking for successful Six Sigma implementation

如果你轻视了六西格玛，那你所领导的项目就有可能沦为旷日持久的战争。

Random.lognormvariate Return a floating point value with a log normal distribution; the natural logarithm of this distribution is Gaussian with mean 'mu' and sigma 'sigma'.

返回a浮点值与a日志正态分布；的自然对数的分布是高斯，平均'mu'和西格马

Some conclusions are inducted through the study: first, grid nudging with the rountine observed data in the MM5 simulation of atmospheric duct affects less over the sea than the land;Second,how much of sigma levels have great influence on simulation of atmospheric duct and the MM5 simulation with more sigma levels depicting the atmospheric ducts are reasonable; Last, multiple nests are allowed on a given level of nesting domain in the MM5 model.

通过研究得到了以下结论：(1)利用常规资料进行格点同化对海上大气波导影响较小，对陆地影响较大；(2)垂直分层对大气波导特征参数影响明显，层数较多描述大气波导比较合适；(3)对于海上大气波导，细网格刻画大气波导特征参数比较细致，但粗网格的模拟已经足够进行大气波导分析。

Chapter three illustrates how to calculate the sigma level and deduces the function between the sigma level and nonconforming rate whether the process has shift or not.

第三章介绍西格玛水平的计算方法，推导出过程无漂移和有漂移时，西格玛水平与产品不合格品率之间的函数关系式。

This dissertation firstly introduces the content, core concept as well as the development of 6 sigma management method and analyzes the theory of using 6 sigma to improve bank's competitiveness; then it summarizes the experience of oversea bank on practicing 6 sigma management method based on the illustrations of Bank of America and City banking group; Next it goes to the necessities and feasibilities of 6 sigma management for domestic banking sector, indicating the strategic goals and significance for domestic banks to implement 6 sigma management; Finally, it discusses the way to implement 6 sigma management and relevant factors, including the barriers of technology, management and culture which are confronted by domestic banks during the implementation of 6 sigma management; the role and function of 6 sigma management in the ongoing domestic banking sector reform; the strategy and process to implement 6 sigma management system; the way to launch 6 sigma projects.

We study the relation between topological sigma models and generalized geometries. The existence conditions for the most general type of topological sigma models obtained from twisting the N=(2,2) supersymmetric sigma model are investigated, and are found to be related to twisted generalized Calabi-Yau structures. The properties of these topological sigma models are analyzed in detail. The observa....

六标准差从1987年在摩托罗拉公司推行至今，已近20个年头，从一开始制造面的改善，延伸到非制造性的企业流程当中，它不但有效地变化员工能力与态度，也为企业带来突破性的营运改善，全方位提升企业竞争力；但事实上，六标准差管理活动导入对企业是一大变革性的挑战，因为其中牵涉策略、组织。。。。

In this chapter, we compare the two different points of the quality economic benefits. We not only establish the econometric model from the traditional viewpoint, but also deduce the econometric model to evaluate the economic benefits of Six Sigma base on the Quality Engineering and Loss Function of Taguchi. Our research has proved that the excess cost decreased quadratically by the increasing of the sigma level.

比较了两种不同的质量经济效益观，不仅建立基于传统观的经济效益计量模型，笔者还基于田口玄一博土的质量工程学和质量损失函数建立六西格玛管理经济效益的计量模型，验证了六西格玛管理的观点，即随着西格玛水平的提高，企业的额外成本呈曲线下降的趋势。

The Six Sigma Black Belt should be familiar with research that quantifies the benefits firms have obtained from Six Sigma.

六西格玛黑带应熟悉将通过六西格玛取得的利益的量化研究。

The results show that the relationship betweentotal potential energy and time step exhibits periodic characteristic when sigma-3symmetric twist grain boundary model and sigma-3 tilt grain boundary model slide atOK. But for sigma-13 asymmetric tilt grain boundary, the relationship between totalpotential energy and time step exhibits damp surge characteristic.

结果发现，∑3对称扭转晶界模型与∑3对称倾侧晶界模型在0K滑动时，系统的势能与计算步数之间的关系曲线呈现周期性变化的规律，而∑13非对称倾侧晶界模型系统的势能与计算步数之间的关系却呈现阻尼振荡特征的变化规律。
