1. The thermodynamic and equilibrium constant criterion of the silver leaching with cyanide is deduced.

2. According to thermodynamic principle, this thesis reconsiders the equilibrium constant of ideal gas reaction.

3. Based on the experimental data, the partitioning equilibrium constant of L tryptophan L Trp was obtained.

4. In this paper, the rate constant and equilibrium constant of the crack reaction of methyl silicane were obtained with the transition state theory and quantum chemistry calculation.

5. A prediction model for 5 types of scales is established by using solubility product and theory of dissociation equilibrium constant.

6. This paper mainly deals with the problem of the dimension of equilibrium constant and numerial value.

7. Models based on supposed reaction mechanism were built; reactive extraction equilibrium constant K11, K12 were got by linear or non-linear regression of experiment data.

8. This is best expressed in the form of an equilibrium constant.
