Knowledge we gain from experience is a posteriori, and what we can know independent of experience is a priori.

Knowledge of this kind is called a priori , in contradistinction to empirical knowledge, which has its sources a posteriori , that is, in experience.

我们称这种知识为"先验"。与之相对应的概念是"经验知识"——后验

同时，作者给出的数值计算方面的例子也显示了这一方法的效力。

The implicit iterative method was applied to the linearized Newton equation, and the key step in the process was that a new reasonable a posteriori stopping rule for the inner iteration was presented.

对线性化后的Newton方程用隐式迭代法求解，关键的一步是引入了一种新的更合理的确定迭代步数的后验准则。
