The germination, expansion and reciprocity of the crack inside the material embody on the crystal bound of the material. So, in this study we can change the bourgeon and extend condition of the tiny crack inside the material by design and control the crystal interface structure effectively and provide new research approach for the design and manufacture of the machinability ceramic.

由于材料的破坏和加工都决定于材料内部微裂纹生成的难易程度和扩展程度，而材料内部裂纹的萌发、扩展和相互作用集中表现在材料的晶界和相界面上；因此，本研究通过有效的设计和控制界面结构，改变材料内部微裂纹的萌生和扩展条件，为可加工陶瓷的设计和制备提供新的研究途径。

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。

Interference is most difficult to be avoided while measuring the weak signal, Especially when the signal is only at microvolt level.X9313 is a kind of digitally controlled dissurbacne potentiometer produced by Xicor company.We succeed in using it to solve the problem that the signal is too strong, and get the useful signal in a weak signal measurement device.

微信号检测中最难避免的就是干扰问题，特别是在信号仅为微伏级时，信号相对于干扰来说，几乎被完全淹没，因此，研究如何在干扰信号很大的情况下尽可能地检测出有用信号有着极其重要的意义。X9313是Xicor公司推出的一种数字电位器，在某微弱信号检测装置中，采用X9313可成功解决干扰信号过大的问题。

By comparative analysis of applicability, we concluded that the microcapsule from sodium alginate used in carbonless copy paper had the same advantages as domestic and foreign抯 in the characteristic of use, stableness and the speed of color development and so on.

证明了以海藻酸钠为壁材单凝聚法制备的无碳复写纸用微囊具有较高的包埋率、不渗透性、稳定性及一定强度；通过应用性的对比分析，认为以海藻酸钠为壁材自制的无碳复写纸用微囊在使用性能、稳定性、显色速度等方面均可达到国内外无碳复写纸的水平。

Micrococcal lysis assay of the milk samples showed that the cDNA was efficiently expressed in the mammary glands with similar expression levels ranging from 60 to 87 mg/L. Different tissues of each vector-injected mouse were assayed for transcription of hLYZ mRNA by dot-blotting and for expression of hLYZ activity by Micrococcal lysis assay. The results showed that expression of the three recombinant vectors was mainly restricted to mammary glands with some degrees of ectopic expression in spleen, intestines and/or kidney.

A The slimmest single filament is most similar to F-actin in size with ～7 nm width at half height and ～35 nmpitch ; the filaments have much wider diameter than the slimmest F-actin ; The branch filament could be con-stituted of two enlaced slimmer filaments , forming the branch in the joining point of another filament ; Two fila-ments are aligned side by side , and thought that there might exist certain interaction between them , which could be theearly step for further assembly of giant filaments.

Micro-tube lysosome with ACPase positive was firstly found since 1973, this kind of structure was observed in many cells, and called line lysosome, these two kinds of lysosome were regarded as manifestation pattern in different period, and was round when it was in relative silence, and line when activating state.

微管是细胞骨架中最粗的一种纤维丝，在活细胞内微管是一种动态的结构，在一定条件下可聚合或解聚，因此细胞内呈现了各种形态的排列方式，以适应变动的细胞质和完成它们各自的功能。

Then PLGA Micro spheres can promotes the proliferation of osteoblast in a long perlod because of the controlled release of bFGF from microspheres. The PELA microspheres satisfied the proprty reguirement of controlled release, but the biological activity of the released bFGF is partially destroyed.
