String suture Tenon s capsule is a abstract and informal way to be used in artificial eye seat of hydroxyapatite.

荷包缝合眼球筋膜在羟基磷灰石植入术中应用，是一种理想、简便的方法。

HC1, which had the p-hydroxy in its stucture, could form steady ternary equilibrium system HC1-Zr-EDTA with [Zr(H2O)2EDTA].

半花菁染料HC1是一拥有邻二羟基酚型结构特征的染料分子，可与Zr-EDTA螯合物形成稳定的三元螯合物体系HC1-Zr-EDTA。

That is to say that the dehydroxylation is ahead of the structural reorganisation which may be due to the fact that the thermolysis was carried out in the solid state.

也就是说，脱羟基出现在结构重组之前，这可能是由于热解是在固体状态进行的事实造成的。

Using 1-amino-2-phenoxy-4-hydroxyanthraquinone, chlorosulfonic acid ,thionyl chloride,and 3-ethoxypropylamine as raw materials and sodium carbonate as acid-binding agent,C.

Using triethanolamine and thionyl chloride as raw materials,tri-(3-chloroethane)amine is synthesized by substitution reaction in the presence of solvent chloroform.

以三乙醇胺和氯化亚砜为主要原料，通过取代反应合成三(2-氯乙基)胺，再在氮气的保护下，经过与对羟基苯甲醛反应，生成三胺，探讨了合成反应的工艺条件。

However, MeJA treatment decreased DIMBOA and p－Hydroxybenzoic acid content of the third leaf significantly, while root DIMBOA content was increased significantly.

2MeSA处理叶片能诱导叶片中AOC基因、β－1，3葡聚糖酶基因（PR2a）基因及根中BX9基因的表达，使第三叶丁布含量降低，根中丁布含量升高，第三叶对羟基苯甲酸含量显著降低，6μL/L的MeSA处理则使根中香草酸含量升高。

Chromatographic behaviors of six cationic thulium porphyrin complexes have been firstly investigated in different mobile phase.

2首次以六个不同的铥卟啉配合物（四（4-羟基苯基）卟啉铥、四（4-甲氧基苯基）卟啉铥、四苯基卟啉铥、四（4-甲基苯基）卟啉铥、四（4-氯苯基）卟啉铥和四（4-异丙基苯基）卟啉铥）为研究对象进行HPLC分离。

Results Same as hyaline cartilage, the calcified cartilage was stained light flavo-green and weak double refraction by the Picrosirius-polarization method. In the immunohistochemistry analysis of collagen Ⅱ protein, the calcified cartilage was stained strong green fluorescence and the collagen protein parallelled in joint surface near the tidemark. The content of collagen Ⅱ protein was (20.16%±0.96%) of tissue dry weight by amino acid analysis, and that of the hydroxyapatite was (65.09%±2.31%) of the inorganic composition in calcified cartilage.

结果 天狼猩红染色见钙化软骨层与透明软骨层一样黄绿色淡染、弱双折光性；Ⅱ型胶原蛋白免疫组织化学分析，钙化软骨层呈强绿色荧光，潮线附近的胶原蛋白呈板层平行分布；氨基酸定量分析钙化软骨层Ⅱ型胶原蛋白含量占组织干质量的（20.16%〖KG-*4〗±0.96%）；X-射线衍射定量分析钙化软骨层中的羟基磷灰石含量占无机成分的（65.09%±2.31%）。
