Univariate indices are not adequate for assessing the capability of processes with multiple characteristics. Among all developed multivariate process capabilities, index has the most accurate estimation of Cpm. takes into account both the ratio of the tolerance region to the process region and the probability of nonconforming product. However, the exact probability distribution of is too complicated to be derived. Consequently, the related hypothesis testing and confidence interval cannot be developed.

在众多的指标当中，单变量制程能力指标的发展已趋成熟，而多品质特性的制程能力指标还在持续的发展中，其中多品质特性制程能力指标是所有多品质制程能力指标中估计值最准确的指标，但在利用多品质制程能力指标Cpm来评选两个制程的制程能力时，由於指标之机率分配过於复杂，迄今未能推导出其相关的统计假说检定或信赖区间，因此无法发展出检定两个制程能力指标Cpm是否有差异的统计检定程序。

Methods: The authors conducted medical record reviews and telephone interviews of 106 consecutive patients with ACL reconstruction using quadrupled semitendinosus-gracilis autograft from 2004 to 2006. Data included anthropometric measurements (height, mass, gender, and age at the time of surgery). Hamstring diameter was obtained using cylindrical sizers in 0.5-mm increments and recorded in the patient's surgical record. Correlation coefficients and stepwise, multiple linear regression were used to determine the relationship between the outcome variable and the predictor variables (age, gender, height, mass, and BMI). Independent sample t tests were used to compare hamstring graft diameter between genders.

从2004年到2006年作者对106名相关的采用股四头肌半腱肌-股薄肌自体移植重建前十字交叉韧带的病人进行了病历综述和电话随访，资料包括人体测量结果(手术时的身高，体重，性别和年龄)，腘绳肌肌腱的直径用计算机圆柱分检器以0.5毫米的增值测量并记录在病人的手术病历中，相关系数和逐步，多个直线回归被用来确定结果变量和猜测变量(年龄，性别，身高，体重和体重指数)之间的关系，独立样本的t检验被用来比较不同性别之间的腘绳肌腱移植物的直径。

Based on the data of listed companies suiting study, this paper tests the expropriation by controlling shareholder in public companies. The results show that the connection between the expropriations by the controlling shareholder with the proportion of controlling shareholder is a reversal 'U', the expropriation by the controlling shareholder is significantly negative related with the shares of the second shareholder, and the expropriation by the controlling shareholder is significantly positive related with the rate between debt and asset.

以我国1998 和1999 年新上市的符合研究要求的公司作为研究样本，对母公司侵占上市公司资金行为进行了研究，以第一大股东对上市公司资金侵占净额占上市公司总资产的比例为研究指标，对股权结构变量和关联交易变量进行回归，得出：上市公司第一大股东的持股比例，与其对上市公司的关联交易型&隧道挖掘&资金占用成倒&U&型关系；上市公司第二大股东的持股比例，与第一大股东对上市公司的关联交易型&隧道挖掘&资金占用成显著的负相关关系，第二大股东对于抑制第一大股东的侵占行为具有一定的作用；上市公司的负债比例越高，大股东对上市公司的资金占用就越多等结论。
