The test results show that density and the total phosphorus content of HEDPA have linear relationship. The content of phosphorus can be converted by subtracting the contents of impurities, namely phosphorous acid and orthophosphoric acid, so that the content of active component can be determined directly with density.

通过实验发现密度与HEDPA中总磷含量呈线性关系，减去杂质即亚磷酸和正磷酸含量换算出磷含量，即可通过测量密度直接测出活性组分的含量。

The result indicated that: the solubility of phosphorus pentafluoride in aether was decreasing as temperature rising; when temperature rises from 0℃ to 30℃, the solubility of phosphorus pentafluoride in aether decrease from 1.5448g/mL to 0.7335g/mL.

通过实验发现，五氟化磷在乙醚中的溶解度随温度的升高而下降，当温度从0℃上升至30℃时，五氟化磷在乙醚中的溶解度从1.5448g/mL下降到0.7335g/mL。

The process of the present invention consists in bringing into contact, on the one hand, gaseous phosphorus pentafluoride or a gaseous mixture comprising phosphorus pentafluoride and hydrochloric acid, and, on the other hand, a solution of lithium fluoride in hydrofluoric acid, in a column (10) having a sufficient number of transfer units to carry out the reaction of PF5 with LiF under the chosen conditions of temperature, of pressure and of molar ratio of the two contrasting reactants and with complete or substantially complete absorption of the PF5 in the column.

本发明方法是让气态五氟化磷或五氟化磷与盐酸的气态混合物与氟化锂的氟氢酸溶液在塔（10）中接触，该塔转化单元数足以在选定温度、压力与两种反应剂摩尔比条件下使PF5与LiF反应，塔中五氟化磷完全或基本完全被吸收。

Results The levels of plasma ionized calcium and serum phosphorus were elevated ( P .001, P .05) with increased urinary excretion of calcium and phosphorus as compared with the controls ( P .001, P .05), indicating a negative calcium and phos...

结果甲状腺功能亢进症患者的血游离钙水平（1.22±0.09mmol／L）与24小时尿钙排量（6.5±2.5mmol／24h）显著高于健康对照组（1.18±0.05mmol／L和3.1±1.2mmol／24h，P值均＜0.001）。

The RE of TP, COD and turbidity except NH4+-N in the aeration process by adding AS and PAM for enhanced chemical phosphorus removal increased by 7.3~59.2%, 5.0~20.3% and 10.9~34.7%, respectively. Given enough dissolved oxygen, the nitrification was not affected by adding AS and PAM in the dosage range of the study. The RE of TP, COD and turbidity by postpose coagulation were better than by simultaneous coagulation, however, coagulation and sedimentation equipments were needed in postpose coagulation process. Therefore simultaneous coagulation was more suitable for transformation of AB process for chemically enhanced phosphorus removal.

曝气过程中投加AS和PAM复配化学强化除磷，总磷、COD、浊度去除率分别提高了7.3～59.2%、5.0～20.3%、10.9～34.7%，但不能提高氨氮的去除率；在溶解氧足够时，本研究投加量范围的AS和PAM的加入对硝化作用无影响；后置混凝对TP、COD、浊度的去除效果优于同步混凝，但需增加混凝沉淀设备，因此同步混凝更适合于于AB工艺的化学强化除磷改造。
