术语“极值”的详细信息

英译术语:

extreme values

汉语语境:

极值是一个函数的极大值或极小值。如果一个函数在一点的一个邻域内处处都有确定的值，而以该点处的值为最大（小），这函数在该点处的值就是一个极大（小）值。如果它比邻域内其他各点处的函数值都大（小），它就是一个严格极大（小）。该点就相应地称为一个极值点或严格极值点。

英语语境:

The extremum is the maximum or minimum of a function. If a function has a definite value everywhere in a neighborhood of a point and the value at that point is the largest (small), the value of the function at that point is a maximal (small) value. If it is larger (smaller) than the function at other points in the neighborhood, it is a strictly maximal (small). The point is then called an extreme point or a strictly extreme point.
