In empirical research of psychology, the basic logical starting point is variable, and the nature of research is the relationship between variables. 心理学实证研究的逻辑起点是变量,本质是研究变量之间的相互关系;
A symbol ( like x or y) that is used in mathematical or logical expressions to represent a variable quantity. 用在数学或者逻辑表达式里代表一个可变量的符号(如x或者y)。
Another important point in the above example, when doing logical comparisons always put the variable on the right side, like above. 在上面的例子里还有一个非要重要的问题,就是当做逻辑比较时,要把变量放在右边,就像上面的。
For his real intention lies in carving out a new logical relation and tapping the new objects of study, instead of caring about what form the variable is. 德奥弗拉斯特本意在于开拓新逻辑关系,挖掘新研究对象,并非在意变项为何形式。
The mathematical model of truss structural optimization containing logical variable is presented in this paper. This model contains a logical variable-truss types, structural design of optimization is divided into two steps. 提出了含有逻辑变量的桁架结构优化的数学模型,该模型包含有桁架类型这一逻辑变量,把结构优化分成两步来求解。
This paper introduces the design method of fuzzy logical variable structure controller which has excellent characteristics and omits the mathematical descriptions. 本文介绍了根据变结构系统概念的一种模糊逻辑控制器,它省去了对系统进行精确数学描述的要求而保留了变结构系统的优良品质。
A theorem has been put forward and proved, which reveals the general and practical significance of converting high variable logical function into low variable logical function and of using small Karnaugh map for simplification. 提出并证明了一个定理,该定理揭示了将高变量逻辑函数转化为低变量逻辑函数并用小卡诺图来化简的一般意义和实用意义。

Simplification of logical function by entering variable in Karnaugh Map 应用引入变量卡诺图化简逻辑函数
The infeasible solutions violating either logical relation constraints among activities or resources constraints can be avoided through introducing a dimensionless variable named extended float time rate and utilizing penalty function. 通过引入无量纲化的扩展工时率变量和罚函数,则可以避免求解得到不满足作业间逻辑关系或资源约束的非可行解。
Logical relation constraints among activities can be automatically satisfied with the help of this variable during the whole computing process. 该变量使得模型中各作业间的逻辑关系约束在求解过程中能自动满足。
