1. Both high temperature shock and fluoride solution administration could cause great change in CAT activity and the degree of change varied with silkworm race, sex, stage and administration dose.

2. The authors consider that temperature shock treatment to be an effective and simple method to induce triploidy from a commercial point of view.

3. Numerical simulations of temperature shock test for materiel and military equipments were carried out according to the method in GJB 150.5-86.

4. Is suitable for heavy load, high temperature shock dynamic intense mechanical equipment use, centralized lubrication system or gear box.

5. Whether a severe environment computer can endure temperature shock affects directly the reliability of products.

6. It is a kind of glass-ceramic in boron-aluminium-silicon system. It has such trait as resist high temperature, high intensity, temperature shock resistance and excellent electronic property.

7. In addition, the mechanisms of polyploid inducement with C. B treatment and temperature shock are dis cussed.

8. The results show that dolomite material has higher erosion-resisting characteristics to high pH value slag, higher resistant characteristics to temperature shock and higher mechanical washing.

9. Products and systems for the protection and repair of concrete structures - Test methods - Determination of thermal compatibility - Part 5: resistance to temperature shock.
