With the increasing development of science and technology, There are many problems relating to differential equation derived form lots of practi- cal applications, such as whether differential equation has a oscillating solution or not, and whether all of its solutions are oscillatory or not.

随着自然科学和生产技术的不断发展，在许多应用问题中均出现了微分方程是否有振动解存在或者微分方程的一切解是否均为振动解的问题。

Some sensors in the CVT system were calibratted. A wire bale of CVT control system and original vehicle wire were designed and revised. A CVT prototype was manufactured and successfully equipped on the car which brand is duiker. Some matching bench test and road test has been finished. And test results are generally well.

We all know what were its achievements in poetry and prose; but there are some indications, it should be remarked, that, besides its efflorescence in ornamental literature, it was on the eve of throwing out new aptitude for conquest in physical science.

我们都知道它在诗歌和散文上的成就；但必须说明，有些迹象表明在其装饰文学的光辉灿烂以外，它已到了在自然科学中作出新征服的前夕。
