On the applications of the uniformly Besicovitch almost periodic functions to differential equations, the main works are as follows:First, the paper proves that the space of the uniformly B2 almost periodic functions, with a special norm, is a Banach space, and then the Fixed Point Methods could be used in this function space.Second, since the space of the uniformly B2 almost periodic functions is per-fect, the paper investigates the existence and uniqueness of uniformly B2 almost periodic solution of a wave equation involving reflection of the argument by the principle of contraction mapping.

关于一致Besicovitch概周期函数在微分方程中的应用，本文主要做了以下工作：第一，证明了一致B~2概周期函数空间在其特定范数下构成Banach空间，从而可以在此函数空间上应用不动点定理；第二，由一致B~2概周期函数空间的完备性，应用压缩映像原理，讨论了一类满足一定初始条件的带反射变量的波方程一致B~2概周期解的存在唯一性。

The results showed that 9 pathogen collections of Sporisorium reilianum were divided into 3 pathogenic types in which there were type A with high pathogenicity, type B with moderate pathogenicity and C with weak pathogenicity. Type A were originated in most important corn-grown areas including Changchun ,Jilin,Gongzuling and Changling where corn head smut usually occurs severely, type B were collected from Siping,Tonghua ,Songyuan,Yanbian, and type C were collected from Baicheng where corn head smut usually occurs very lightly.

QUITE GOOD就相当于分数A,B只是AVERAGE,"OK","C"则是差,这点Cahill自己在他的评论中都写到了: I might add, finally, that my experience with the British academic grading system as an outside reader for Hong Kong University several years ago made me conscious that your gradings are stricter than ours; a student here would be quite unhappy with a B or 13grade in a seminar, but maybe the same isn't true there.

&我最后想要说，我在几年前做过香港大学的校外分数重估专家，这个与英式学术计分系统的经历让我感到你们的计分法要比我们的严格，在这里严格学术会对一个B和一个讨论课的13 级分数很不满，但是这在你们那里也许不是这样。&同时Cahill 自己已经在他的意见书中承认了他已经了解了有关这个分数和论文的背景，，并且还多次着重指出&From the viewpoint of the instructor…&根据以这个课程的指导教师的观点。。。
