在催化反应过程中，一般都是对映体选择性酶与化学试剂的相结合，化学试剂一般常用于催化非活性对映体发生去消旋反应或是回收去消旋化过程中的中间体。

In spite of the fact that the first patent on transient operation of chemical reactor was applied in 1938,the forced unsteady state operation of chemical reactors as an attractive novel technology and its associated profound theory are a new area of study in chemical reaction engineering.

尽管1938年就申请了化学反应器动态操作的第一个专利，但是化学反应器人为非定态操作作为一种具有吸引力的新技术和与之相联系的复杂理论仍然是化学反应工程研究的一个新领域。

A series of grafting-modified dregs were prepared and the influence of monomer ratio, rotation speed and time of ball milling on grafting efficiency was investigated. It is demonstrated that mechanochemical techniques of ball-milling can smash up dregs as well as initiate in-situ grafting polymerization. Thus the usableness and uniform dispersion of dregs in polymer matrix can be ensured.

通过红外光谱和热失重分析证明，球磨过程在粉碎细化废渣的同时，可由力化学作用引发原位接枝聚合反应，将改性聚合物化学键接在废渣表面，使废渣具备与聚合物共混、在聚合物基体中均匀分散的基本条件。

The content of kaolinite varies in the range of 80%to 95%.Two occurrences of kaolinite are rev ealed:one is in the form of aggregate of vermiform crystals;another is in the form of cryptocrystalline or colloidal materials.Its crystallization index is calculated to be 0.54～0.74a nd 0.47～0.53,indicating its higher degree o f order.Chemical analyses show that the compositions of kaolinite are close to its theoretical values.

光学及扫描电子显微镜、 X射线衍射分析和红外分析等系统性研究的结果表明，高岭石主要有两种存在形式，一种呈蠕虫状集晶，另一种是隐晶质或胶状高岭石，测得其结晶指数分别为 0.54～ 0.74和 0.47～ 0.53，说明其有序度偏高；化学分析结果表明，其化学成分接近于高岭石的理论值， Al2O3含量达 35%～ 37%， SiO2含量为 47%～ 48%，碱金属、碱土金属及其他氧化物含量很低。

In this study, the expression and function of FGF-13 in developmental follicles and skin during embryonic development,normal vibrissa follilce stem cells and wound follicles in vitro were obserbed,so as to illuminate the possible role of FGF-13 in the skin follicles during embryonic development and damage healing and provide the experimental base for further studying the characteristic and mechanism of the role of FGF-13 in skin.

采用免疫组织化学(Immunohistochemistry，IHC)、免疫细胞化学(Immunocytochemistry， ICC)和原位杂交(in situ hybridization，ISH)技术及体外大鼠触须毛囊的器官培养，研究了三种不同的生物学过程中FGF-13在皮肤毛囊中的表达及作用。
