That this tactic is morally, rather than academically, motivated is made very clear by the fact that there is no corresponding border region just above the class boundary;

这种措施是出于道德而不是学术的考虑，可以确定的事实是，在分数线以上并不存在这样类似的“边界区域”；

According to uniqueness theorem, the integral formulations of the first class boundary condition and the second class boundary condition are given form the above integral formulation.

根据边值问题的唯一性原理，由此积分解表达式给出了第一类和第二类边界条件的积分解表达式。

Some universities, for example, identify a "border region" of marks just below a class boundary in which a board of examiners is permitted to move a student up to the next degree class.

比如说，一些大学会定义一个略低于分级分数线的“边界区域”，允许该分数领域内的学生升级进入分数线两侧高一级的档次。
