DOD：定义域
“Domain Of Definition”是数学与计算机科学中常用的专业术语，中文译为“定义域”。为方便书写与交流，通常将其缩写为DOD，尤其在编程、函数分析和数据处理等领域频繁出现，用于指定变量或函数的有效取值范围。
Domain Of Definition的英文发音
例句
- Sometimes there is the domain of definition.
- 有时定义域(DOD)只是一个范围。
- So, see, the problem with that vector field here is precisely that its domain of definition is not simply connected because there is a hole, namely the origin.
- 但还可能存在问题，有的定义区域不是单连通的，因为这里有个洞，也就是原点。
- So, we also need to check the values of f at the boundary of its domain of definition or at infinity.
- 总之，检验定义域(DOD)边界的函数值，或无穷远处的值。
- A regular parametric transformation does not change the shape of a parametric curve, but the mapping of the points in the domain of definition of the curve onto the points on the curve is changed and therefore the curve parametrization is changed.
- 正则参数变换不改变参数曲线的形状，但改变了从曲线定义域(DOD)内的点到曲线上点的映射关系，因而改变了曲线参数化。
- A method for automatically dividing and marking scale interval for coordinated axes according to domain of definition and domain of function when graphing functions on CRT is suggested.
- 本文提出一种用CRT显示一元列表函数图象时，根据被显示函数的定义域(DOD)和值域，计算机自动进行坐标刻度的划分和标值的算法，给出了程序框图和说明。
