Kaolin, one of inorganic material, is composed of more parallel crystal layers of octahehedrdal alundum and crystal layers of tetrahedral silica. Rasicals K-O· are formed hydroxyl by initiator. On the surface of octahedral alundum.

高岭土是由许多平行的铝氧八面体晶层和硅氧四面体晶层组成，铝氧八面体的OH在引发剂作用下可形成自由基K-O·，然后可引发丙烯酸-丙烯酸钠进行接枝聚合。

The influence of position of the substitution, strength and number of donors and acceptors, and their coplanarity and asymmetry is discussed. The results indicate that the molecules may have larger first hyperpolarizabilities when the molecules have stronger and more donors and acceptors, large asymmetry of HOMO and LUMO, better coplanarity and higher accentricity. This work attemps at finding out the relationship between the structure and the property, thus providing theoretical basis for designing nonlinear optical molecules.

进一步研究体系中取代基的位置，给体与受体的数量和得失电子的能力，分子的共面性和对称性对分子第一超极化率的影响，结果表明，有机分子拥有更多数量与更强得失电子能力的给体和受体，最高占据分子轨道和最低未占据分子轨道空间分布的不对称，具有较高的原子共面性和较低的分子中心对称性，都能显著增加

从因正畸需拔除的健康牙体表面获得牙骨质基质提取物，分别观察不同作用时间、不同浓度的牙骨质基质提取物对牙龈成纤维细胞和牙周膜成纤维细胞在牙体表面附着的影响。

Two ends of s shape bent waveguide respectively coaxially link perpendicular waveguide input and output section.

直波导输入输出段、S形弯曲坡面结构、长方体结构和平面光传输波导位于基版的表面，S形弯曲波导位于S形弯曲坡面结构的表面，直波导输入输出段位于长方体结构的表面，基版上的直波导输入输出段和位于长方体结构上的直波导输入输出段通过S形弯曲波导连接，S形弯曲波导的两端分别与直波导输入输出段同轴相切相接。

Results; Facial width was correlated to most of craniofacial width; basal bone of maxilla was adapted to facial type; nasal width was related to craniofacial width in high-angle subjects; condyle width was related to adjacent structures; gonial width was related to condyle width.

结果：高低角骨面型中面宽与整个颅面部横向发育关系都较密切；上颌基骨宽度与面型协调一致；高角骨面型鼻宽受整个颅面宽度的影响较大；下颌升支上下部分的宽度是相互关联的，髁突的宽度与邻近骨骼的宽度有关。

When the concentration of zinc nitrite is lower than 0.1 M,(002) is the prior face for zinc oxide. As the concentration raise, the other kinds of crystal face would appear. Among those data,(002) grows the best when the concentration of zinc nitrite is 0.06 M. We add lactic acid and citric acid respectively; there is an carboxyl group on the lactic acid and three carboxyl groups on the citric acid. The monodentate of lactic acid helps the growth of zinc oxide, compared to the tridentate of citric acid which can only produce zinc oxide film under very low concentration, but the growth of (002) face is not that stable as adding the lactic acid and zinc will electrodeposit to substrate.

实验中，当硝酸锌浓度低於0.1 M 时，氧化锌以(002)面为优选位相，当浓度提高，其他晶面将会出现，当硝酸锌为0.06 M，(002)晶面成长最佳，分别加入乳酸和柠檬酸，乳酸结构上有一羧基团而柠檬酸有三个羧基团，单芽基的乳酸有助於氧化锌成长，对照於三芽基的柠檬酸，则必须在极低的浓度下才能制备氧化锌薄膜，但(002)面成长却没有添加乳酸来的稳定而金属锌也会电沉积到基板上。
