Firstly, this paper definited pseudometric d for n -foldproduct of σ-algebra A of subsets of a given set X , and definited indicator function ; secondly, gave the concept of differentiable of set function at S° and concept of partial derivative at S° with respect to the ith argument Si through indicator function, and defound the weak efficient solution of and optimality necessary condition; Finally, obtained three weak duality results and strong duality results under generalized convexity conditions.

首先，对已知集X的子集的σ-代数A的n-折积A^n，定义了伪度量d，给出了相应的特征函数〈h，Is〉；其次，通过特征函数给出了集函数在S 可微的定义及集函数在S 关于第i个变量Si的偏导数定义；给出了多目标规划问题的弱有效解概念及的最优性必要条件；最后，分别在目标函数和约束函数的3种较弱凸性条件下，研究n-集函数多目标规划问题的对偶问题，获得了3个弱对偶结果和强对偶结果。

There are just so many variables in this kind of analysis that's not for us.

这种分析中有如此多的变量——这不适合我们。

The model include serval structural equations so that it can be used to describe the time series' variate and transitions under disparate states.

该模型包含有多个结构方程，从而能够刻画出时间序列变量在不同状态下的变化及转换过程。

Some CT characteristics of BCSDH were studied first.Then,the risk factors for BCSDH were determined by logistic regression model from the following variates: age,gender,prediagnostic duration,site for injury force,coma experience and CT showing after injury.

先研究其CT表现，然后采用多因素Logistic回归分析从以下变量中，如年龄、性别、伤后&潜伏&时间、受伤着力部位、受伤时有无昏迷经过、伤时CT表现等确定BCSDH发生的影响因素。

In each subperiod, the DUMOP is seen as a static multi-objective optimization problem by taking the time parameter fixed.

该方法首先将DUMOP的时间变量区间进行了等间隔分割，在每个子区间上把DUMOP近似为静态多目标优化问题。
