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 classboundary;
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 classboundary condition and the second classboundary 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 classboundary in which a board of examiners is permitted to move a student up to the next degree class.
