In Chapter 3, two calixarene-linked chitosans were synthesized by the reaction of chitosan with 1,3-diglycidyl calix[4] arene.

第三章以双缩水甘油基杯[4]芳烃与壳聚糖中的氨基或羟基发生交联，得到了两种结构不同的网状聚合物。

RESULTS AND CONCLUSION: PCHC: Intra-bone mechanical strength was lower at 2 weeks, the lowest at 4 weeks, but then closed to intension of normal cancellated bone at 8 weeks, higher than normal cancellated bone at 12 weeks, and recovered to the level of normal cancellated bone at 16 weeks.

结果与结论：多孔碳酸化羟基磷灰石骨水泥：2周时的骨内力学强度较低，4周时降到最低，8周时接近正常松质骨强度，12周时超过正常松质骨强度，16周时恢复到正常松质骨水平。

Capric, lauric, myristic, palmitic and stearic acid were fatty acids chosen to study the effect of the length of hydrocarbon chains on properties of pigments.

脂肪酸部分中，以含有十、十二、十四、十六、十八个碳原子的羧酸为对象，考察了不同脂肪链长度的羧酸对颜料的改性效果。12-羟基硬脂酸和油酸与硬脂酸结构的差异导致颜料性能的变化。

By means of covalent coupling with the activation of 1-ethyl-3-(3-dimethyllaminopropyl) carbodiimide hydrochloride and N-hydroxysulfosuccinimide.

利用自组装技术将三巯基丙酸固定在金电极上，以1-乙基-3-（3-二甲氨基）碳二亚胺盐酸盐和N-羟基硫代琥珀亚胺作为活化剂，将甲基对硫磷抗体以共价键形式固定在三巯基丙酸自组装单分子膜修饰的金电极上，制备了一种免疫传感器。

METHODS. Recombinant human collagen (13.7%) type I or III was thoroughly mixed with 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide and N-hydroxysuccinimide.

I型或III型重组人胶原蛋白（ 13.7 ％）被彻底与1 -乙基- 3 -（ 3 -二甲氨基）碳化二亚胺和N-羟基丁二酰亚胺混合。

In all those complexes, no matter which conformation IDA assumes (mer- or fac-style), the two 0 atoms of 1N2O are both from carboxylic hydroxyl. However, by comparing the bond length, we can find that O(4) and O(2) atom is from different group in this complex, 0(4) atom from carboxylic hydroxyl, whereas, 0(2) from carboxylic carboxide.

值得注意的是：在这个双核配合物中，我们首次发现一种新颖的配位方式：IDA上与金属离子配位的三齿螯合原子是亚氨N原子、一个羧基上的羟基O原子和另外一个羧基上的羰基O原子。

Currently, two kinds of reactions are often employed, including derivation of carboxy groups and direct addition.

目前CNTs的共价修饰主要通过两类反应来实现：羟基的衍生反应和直接加成反应。

At the same time, the data of tatal acidic group, phenolic hydroxyl group and carboxy were obtained.

给出了各种原料煤腐植酸中总酸性基、羧基、酚羟基的分析数据。

This one mode pays close attention to network credence foundation of the businessman very much.
