The first case is the variable depth with a fixed notch-width and the second case is variable width with a fixed notch-depth. It can be observed fromthe moment-curvature curve of the first case that the magnitude of the moment is larger for the deeper depth than that for the shallow depth.

由有限元素ANSYS 分析结果可以观察出，在控制固定曲度做循环弯曲负载时，弯矩－曲度曲线图显示出，在固定凹槽的宽度，当深度较浅时，达到设定的控制曲度所需施加的弯矩相对於凹槽深度较大的圆管要大的多。

The use of a variable like val to control a loop happens so often that the language defines a second control structure, called a for statement , that abbreviates the code that manages the loop variable.

由于需要频频使用像 val 这样的变量控制循环，因而 C++语言定义了第二种控制结构，称为 for 语句，简化管理循环变量的代码。

In order to resist the noise data, Variable Precision Rough Set Theory was proposed. In this paper, the Variable Precision Rough Set Theory is applied to judge the development degree of a region. It can resist the interference of the noise and get simple rules, but does not change the ability of assorting.

为了提高在实际应用中对噪音数据的适应能力，Ziarkio提出了可变精度粗集理论，本文把可变精度粗集理论应用在一个判断地区综合发展程度的系统，实现了抗噪音的干扰，同时也大大简化了原始数据集。

At the present time, these multiple variables are often switched into a dichotomized variable according to some classification criteria, and then the dichotomized variable is analyzed.

然而，对于复杂性状，我们往往很难判断这种定性划分的准则同疾病基因的遗传有何关系，所以用多个原始变量的数据来定位易感基因可能更为理想。

The results of a logistic multi-factor regression analysis by binomial classification, with psychological health as dependent variable (dichotomized variable : SCL-90 factors which has 1 item or above with scores equal or bigger than 2 are valued 1, thoses with an average score smaller than 2 are valued 0) and all factors of life events as independen variables, showed that the family-related bad incidents, bad incidents of work and study and bad incidents of sociality problems were modeled, in which three factors were dangerous factors.

研究结果：1、大部分社区医务人员、社区管理人员、社区居民认为社区需要有精神卫生服务，不同文化程度、不同性别、不同收入、不同年龄、不同婚姻状况的社区居民对社区精神卫生服务的需求是不相同的。2、根据SCL-90的筛查结果，发现有心理问题者353人，心理问题总检出率达30.2%。

Experiments were applied with variable numbers of joined federates and variable length of time advancing step. Major factors that affecting time advancing efficiency of HLA compatible distributed simulation system was concluded based on the comparison and analysis of the experiment results.

通过不同盟员个数和不同仿真推进时间步长下系统推进效率的实验分析，得出限制仿真系统推进效率的主要因素，并结合航天任务物理模型的特点，设计了一种改进的组件交互方案。

不同的干扰因素对导弹高度控制系统的要求是矛盾的，而利用PID控制并不能解决这一矛盾，为此提出了采用变结构高度控制的方法。

The method of typecasting is done by prefixing the variable type enclosed by parenthesis before the variable name.

该类型转换的方法是由包含在变量名之前的圆括号内的前缀变量类型来运行的。
