It is the same method as usual. And if you are being given a geometric description of a curve then, of course, you will have to decide for yourself what the best parameter will be.
这和平常的方法是一样的，如果给出，一条曲线的几何描述，就不得不自己判断，什么才是最好的参数化方法。
But that obvious observation conceals a precise mathematical description: the link between the severity and frequency of conflicts follows a smooth curve, known as a power law.
用一个很简单的数学式，可以表示为：存活率与冲突频率间呈现平实的曲线关系，这被认为是法的力量。
Description of the tree diameter growth using tree age as independent variable may thus give an inflection point of the growth curve.
树木直径的实际生长年龄小于树木年龄，用树木年龄作为自变量来描述直径生长会导致生长曲线出现拐点。
