Results show that the linear burning rate increases as the pellet density decreases,and the product formation rate of B/KNO3,which affects pressure-time curves,is significantly affected by the pellet size.

The results demonstrate that the formation rate of CO2 hydrate is rather slow in a quiescent system without surfactant,and hydrates are formed only at the gas-water interface.

Then the data were analyzed combined with the calculation theories of hydrate's induction time,formation rate and void fraction.

This paper analyzes the mechanism of methyl acetate formation, the influencing factors of ester formation rate in the terephthalic acid production process, and also analyzes the improvement of Amoco process variables.

The results obtained above indicated that high dietary copper could induce oxidized stress damage in liver;at the same level of dietary copper supplement,the organic copper will lead to much faster H2O2 generation velocity of mitochondria from broiler hepatocyte than inorganic copper.
