查询词典 amine

Under normal temp., PVF2 has a fine corrosion resistance to many organic solvents like halogen, halogenated hydrocarbon, strong oxidant, boiling acid and alkali; UHMWPE has a fine corrosion resistance to inoxidable acid (dilute sulfuric acid, nitric acid and large concen-tration hydrochloric acid, phosphorus acid, hydrofluoric acid, formic acid and acetic acid), ammonia, amine and various alkali and salty solutions. Both materials can't resist the corrosion of strong oxidable acid.

在常温下，PVF2对卤素、卤代烃、强氧化剂、沸酸、碱等多种有机溶剂都有良好耐蚀性；UHMWPE对非氧化性酸(稀硫酸、硝酸及浓度较大的盐酸、磷酸、氢氟酸、甲酸、乙酸)、氨和胺及各种碱、盐溶液都有良好的耐蚀性，两种材料都不耐强氧化性酸的腐蚀。

The experiments show that one portion of amino organic compounds in the shell is changed to the volatilizable amine and the other portion is transformed to the involatile nitrate after pyrogenation.The organic compounds disappear completely at 600℃.They also show that the aragonite phase of calcium carbonate in pearl shell chang with temperature;the aragonite phase transforms to calcite at 500℃, but some of organic compounds is still residual;and calcium carbonate begins to decompose to calcium oxide at 600℃.

实验发现，贝壳中的氨基酸类有机物热降解后部分以胺的形式挥发出来，另一部分则转化为不可挥发的硝酸盐的形式，600℃有机物完全消失；同时，贝壳碳酸钙的文石晶相随温度而变化，500℃时转变为方解石结构，其中仍有部分有机物残留，600℃开始分解为氧化钙。

Chemically, fluoroquinlones are an amphoterics molecule processing major ionizable groups, a basic piperazine amine and acidic carboxyl. The form of drugs was greatly affected by the acidity in aqueous solution. Thus the effect of pH values in aqueous solution on the fluorescent properties of fluoroquinolones was studied in details, the spectral properties of each form was characterized. It was found that the fluoroquinolones exhibit weak fluorescence in strong basic solution.

氟喹诺酮类药物分子结构中既有羧基，又有哌嗪氨基，它们所处环境的pH值对其存在型体有很大影响，因此我们详细研究了水溶液的pH值对该类药物光谱特性的影响，并对于各型体光谱特征进行归属，发现强碱性溶液中其发光较弱。
