1. OBJECTIVE To study the preparation and thermostability of phenazopyridine hydrochloride.

2. The thermostability and freeze denaturation of ATPase activity, total - SH and actomyosin ( AM ) from Charybdis japonica were studied.

3. Research on thermostability and intensity of anion exchange resin based on polystyrene is analysised.

4. Thermostability of enzymes can be altered by single amino acid substitution.

5. The results showed that the thermostability of the composite was improved by the addition of the nano-meter montmorillonite and rose with the increase of the content of the nano-meter montmorillonite.

6. In contrast to iodine, the thermostability of this complex has evidently increased, but it can release iodine molecular and has strong disinfection and sterilization.

7. The effect of montmorillonite nano-meter particle on the thermostability , mechanical properties and intrinsic viscosity number of the in-meter composite was studied.

8. The thermostability of the enzyme decreased with a increase of treating temperature.

9. The thermostability of composite is higher than that of alloy.

10. The shorter the lactation period was, the poorer the thermostability was.

11. It was indicated that the modified coal pitch, which had not only a great deal of mesophase microbead but good thermostability as well, can be qualified to be an excellent carbon precursor.

12. The effects of annealing on superconducting transition and the thermostability of MgB.

13. Drying curve and carbonizing temperature of rice hull powder treated by suitable agents and processes are measured in order to investigate factors influencing its thermostability.

14. In ammonium perchlorate(AP) production, chlorate impurity in the raw material will influence the thermostability of AP.

15. These new acetylation reactions were synthesized with PS of monodisperse particle. Research on thermostability and intensity of anion exchange resin based on polystyrene is analysised.
