It was found that Pd-Co/active carbon catalyst was the optimal catalyst, and Pd-Co/γ-Al2O3 was also good, but silica and kieselguhr were not proper carriers for the object reaction, because of their stronger surface acidity, which could result in the formation of polymer, jammed the micro pores of catalyst, and then resulted in its deactivation. Addition of Bi, Ce and Cu promoters could not improve the activity of catalyst, but La and Ba promoter could enhance the activity of catalyst apparently, and the Co was the best promoter, especially Co was impregnate in advance. It was attributed to that the pre-impregnated Co may occupy the micro pores of active carbon, and cover some bad functional groups on the surface of catalyst, so that the active and selectivity of catalyst could be enhanced obviously.
研究结果表明,Pd-Co/活性炭催化剂是目标转移加氢反应的最适宜催化剂,Pd-Co/γ-Al203效果也较好,而硅胶和硅藻土由于表面酸性较强,容易造成生成聚合物而堵塞催化剂微孔、使催化剂迅速失活;此外,添加Bi、Ce、Cu等助剂时对活性并无改善作用,而添加La和Ba助剂时可使Pd的催化活性有所提高,效果最好的是Co助剂,尤其是先浸渍Co的Pd-Co/C催化剂,原因是Co占据了活性炭的微孔、覆盖了某些对目标反应不利的官能团,使其活性和选择性都有较大幅度的提高。

Microstructural observation revealed that a lot of epitaxial growth fibrous AlN polytype occurred in matrix. Y_2O_3 seems to act as a densifier for in-situ formation material and as medium for growth of fibrous polytype. SiO_2 is the growth promoter for fibrous polytype. The occurrence of fibrous polytype may increase the strength and toughness of AlN ceramic composite material.

During early middle Jurassic period, Quemocuo formation in NQB was offshore lake deposition with marine feature, in SQB was shelf deposition, which indicted that an intense rifting and sea level rising with more large range, and consequently, eroding area was shrunk and deposition area was expanded.4. According to the result of stratigraphic surface features, division and correlation, and the paleographic characteristic, Qiangtang Basin during late Triassic -early middle Jurassic period could be divided into two basin developing stages with difficult tectonic nature, remnent epicontinental basin stage in Carian -early Norian of late Triassic and rifting basin stage in middle Norian of late Triassic - early middle Jurassic period respectively.

Unfortunately, just the lack of design model to guide software design process of EC brings many issues in practices of EC. It is difficult to design reusable EC software based on the basic structure of EC. For example, the EC software aimed to solve function optimization can't be used to solve combinatory optimization without an overall modification.
由于缺少一个软件设计模型来指导演化算法的软件设计过程,仅从演化计算的基本结构出发设计出的软件很难用来求解不同种类的问题,比如针对函数优化而设计的演化算法不经大幅度的修改就不能够用来求解组合优化问题。
