Solubility and stability of calcium arsenates under different CO2 pressures are studied based on the data of precipitation and solution experiments simulated by PHREEQC program. The result shows that calcium arsenates can dissolve incongruently by the effect of CO2 in high pH（pH〉8. 3）and make their solubility higher. The higher the CO2 pressure is, the lower the acidity of the incongruent dissolution is.

文章摘要：通过沉淀和溶解两方面的实验数据，应用PHREEQC程序模拟了砷酸钙在不同CO2分压条件下溶解度的变化情况，发现环境中的CO2可使砷酸钙盐在酸度较高（pH大于8.3）的条件下发生不一致溶解，使其溶解度升高；CO2分压越大，砷酸钙盐发生不一致溶解的酸度越低；CO2主要影响3：2和5：3的砷酸钙盐，而对4：2砷酸钙盐的影响较小。

甜菜锰和铝合并中毒：幼叶褪绿失去光泽，老叶边缘枯黄，脉间有坏死褐色斑点，接着白化，枯萎。这是酸性土壤特有的。

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。

The synthesis of eight compounds ( borneol ester and isoborneol ester) and other esters catalyzed by nanometer solid superacids were also researched. In addition, we still analyzed the distinction of esterification yield of borneol ester and isoborneol ester. The particle size, surface area, changes of profile and acidity of nanometer solid superacids were mensurated and analyzed by TEM, BET, XRD, IR and acid indicator.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
