It is still needed to do some work to determine the deformation parameter β2 for light odd-odd nucleus, like 6Li and to calculate all reaction channels by means of CDCC code simultaneously. It is important to measure the exclusive angular distributions of breakup fragments.In theory, the coupling channel equations have been deduced from one-dimensional to multi-dimensional barrier tunneling. The couplings between the entrance channel and the other channels have appreciable effects on sub-barrier fusion cross section. Instead of single fusion barrier,these couplings lead to a distribution of fusion barrier Dfus.

SRC in SDR is also discussed, and two improved structures of CIC filter are presented. The first one is a CIC decimation filter based on polyphase structure and partially sharpening technique, which is suitable for the situation where the requirements in passband attenuation is not very high while the requirements in alias suppression and operating speed are relatively high. The other one is an improved CIC-Rotated Sinc decimator which possesses improved frequency response, low operating rate and low cost in hardware as well.

On features selection, a features selection algorithm based on rule induction is proposed. Solve some flaws in divide and conquer strategy like algorithm used by Cohen, such as induced rules are not very precise, the latter rules generation lacking enough statistical support and the rule easy to be immature.

在特征属性的抽取方面，提出了一个基于规则推理的属性抽取算法，解决了Cohen采用分而治之策略的算法中的一些缺陷，如推导出的规则不够精确、后续规则生成缺乏足够的统计支持以及易引起规则的早熟等。

In general terms the chemical impurities are measured in a silicon rod obtained through the deposition of a small Trichloro silane sample on dedicated pilot test reactors or directly from a core sample taken from a produced polysilicon rod; both are refined by Float-zone technique (the sampling operation are performed according to the relative ASTM F1723-02 -"Standard Practice for Evaluation of Polycrystalline Silicon Rods by Float-Zone Crystal Growth and Spectroscopy").

Three animals randomly selected from three groups were killed on Day 0 to determine the baseline of PLA2 activity within unmanipulated rat sciatic nerve; other 39 animals underwent operation for model-making of acute sciatic （Maves-modified Bennet-Xie model） on right sciatic nerves, while Sham operations were performed on left sciatic nerves.

Due to the lack of syntax structure of the information in web pages, especially in the semi-structure pages, the traditional natural language processing technology is not applicable to the web information extraction well. And web pages is recognized, explained and shown by browers and viewed by users, in which there is a lot of vison characters. So if the vision information in web pages can be used for information extraction, complex linguistic knowledge would be avoided.

由于Web页面的内容缺乏严格规范的语法结构，尤其是半结构化页面，所以传统的自然语言处理技术并不能很好地适用于Web信息抽取，另外Web页面被浏览器识别、解释和显示并供用户查看和理解，其中包含了大量的视觉特征，如果把Web页面的这种视觉信息应用于信息抽取，就可以避免使用复杂的语言学知识。
