In order to eliminate the judgment error of char reactivity arising from different carbon content of samples,a new parameter called specific maximum weight loss rate was introduced,defined as the quotient of the maximum weight loss rate in non-isothermal thermogravimetric analysis(TGA) experiment to the carbon content of corresponding sample.

The relationship between N/P ratios and maximum specific growth rate of red tide algae was analyzed according to Shelford\'s law of tolerance to study the response mechanism between N/P ratios and red tide algae,and the tolerance model between specific growth rate of red tide algae and N/P ratios was established.

The batch respirometric method was applied for the determination of the concentrations and the maximum specific growth rate(μ^A) of autotrophic biomass (XA) in mixed liquors from aerobic tanks of a full-scale wastewater treatment plant with anaerobic/anoxic/aerobic process and a pilot-scale anaerobic/aerobic process.

Effects of bulk density on mass loss rate during agro-stalks smoldering;

Experimental results show that this method gives predictions which agree with those from the data of mass loss rate by traditional method.

The various materials as fuel are burnt in an experimental device of Room-Corridor structure, the mass loss rate of which, and the relationship of the mass loss rate with the smoke transportation velocity and CO concentration at a distant location are studied in detail in this paper.

Sensitivity analysis showed that the performance of activated sludge system was affected remarkably by heterotrophic decay rate, heterotrophic maximum specific growth rate and autotrophic maximum specific growth rate, so these parameters were studied.
