We define the ADR and the ADRcompensation in the theory research. The paper goes into detail about the ADR theory basis andthe responsibility constitution of other countries and provides the theory basis in order to make itclear why the victims should get the compensation and who should undertake the responsibility.(3)According to the analysis of the data statistical and the investigation, most reports come from themedical institutions while the reports from the production and operation enterprises are extremelyfew, only making up 1%. The speakers are mostly doctors. The serious ADR is about 2% andoccur at different ages. 50 -year-old middle-aged persons and old persons suffer from the ADReasily. In those reports, the ADR caused by using the one drug is about 90%; the ADR caused bythe anti-infection medicine ranks first due to using it wide in clinical medicine and applyingunreasonably. The intravenous injection easily causes the ADR.

This thesis is divided into six parts. The first chapter is preface, the current status of research in the inverse problems for parabolic partial differential equations is reported; the second chapter is "regularization methods for numerical differentiation and their applications ", in this chapter we investigate many regularization methods from a viewpoint of regularization theory and algorithm, some applications in the inverse problems for parabolic partial differential equations are given; the third chapter is "spectral regularization methods". Based on Fourier analysis, within the framework of regularization theory, we apply the spectral methods to some ill-posed problems. Many numerical experiments are done in order to show the validity of the methods; the fourth chapter is devoted to wavelet dual least squares method and a revised wavelet method; in the fifth chapter,we combine finite difference method with method of lines and apply it to the backward heat conduction problem in time; in the sixth chapter "identification problems for unknown source ", the essence and the degree of two problems related to source identification are pointed out, at the same time, some numerical methods are reported.

By and large, the influences of the Garden City Theory on city planning of Republic of China mainly had two aspects. The first was planning of new district in city. This was exactly the same with the means by which Howardbuilt two garden cities--Letchworth and Wewyn in suburb in order to avoidincreasingly expansive London. The second was the decentralism of Chinese city planning after the War of Resistance Against Japan. This was tightly correlated with some West decentralization planning theories such "satellite city","organic decentralization","neighborhood unit" which rooted in the Garden City Theory.
就总体影响而言,一是城市新区的规划,这与霍华德避开日益膨胀的伦敦市区,在郊区进行莱切沃斯和韦林两座田园城市的建设做法如出一辙;二是在抗日战争胜利以后,中国的城市规划多主张分散主义,这又显然与田园城市理论及源于田园城市理论的卫星城市、有机疏散、邻里单位等分散主义的规划理论密切相关。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称;三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起,称之为挽歌体诗人或者史诗诗人,他们被称为诗人,似乎只是因为遵守格律写作,而非他们作品的模仿本质。
