Because supercritical and near-critical water have special solubility, high ion product, low surface tension and high diffusion coefficient, chitosan can be degraded into soluble chitooligosaccharide rapidly.

超临界水具有特殊的溶解度、很高的离子积、较低的粘度、较低的表面张力和较高的扩散系数，使得壳聚糖在超临界水中能够快速降解成可水溶的壳寡糖。

These may because of the bad solubility of product two and three, especially, the main phase of product three is an aluminum sulfate, when be resolved at room temperature to measure the species distribution, one part was not resolved into water, it\'s species was diagnosed as Al_c, so their content of Al_c is high.

在100℃下结晶的聚铝品种的溶解度和Al_b含量均较低，这可能是其絮凝性能差的主要原因。

According to the experiment results, the solid-liquid interface tension between NiCO3 and sodium sulphate solution is larger than that between NiCO3 and sodium chloride solution.

结果表明，碳酸镍在硫酸钠溶液体系中的固–液界面张力较大，微小晶粒在硫酸钠溶液体系中的溶解度也较大。

The calculated results show that activity coefficients of NiCO3 in sodium sulphate solutions are less than that in sodium chloride solutions, and the solubilities in sodium sulphate solutions are larger.

估算结果表明，与氯化钠溶液体系相比，碳酸镍在硫酸钠溶液体系中的活度系数较小，因而溶解度较大。

The main work of this paper is as follows:(1) Ignoring other small content and indissoluble salt, only considering sodium chloride and sodium sulphate, and suggesting these is no Chemical reaction between soil and salt, the phase change rule of salty soil follow the phase change rule of 〓 ternary water and salt system, which obey the phase equilibrium theory.

本文主要进行了以下研究工作：(1)在只考虑NaCl与Na〓SO〓两种易溶盐，而忽略其它在盐渍土中含量与溶解度均较小的盐类，并假定NaCl与Na〓SO〓不与土颗粒发生化学反应的基础上，盐渍土的相变规律实质上是〓三元水盐体系的相变规律，并服从相平衡理论。
