Sensitivity analysis of effect of the secondary air distribution mode on the unburned carbon is studied in this paper,meanwhile,a multi-complex algorithm is employed to perform a search to determine the optimum solution of optimal recursive neural network(ORNN),which is used to set up a boiler property model,so as to obtain currently optimum distribution mode of secondary air.

The basic principle for studying on mechanical specific characteristic drift(MSCD) was given, and it was tested and verified by the compound population mixed with Zaofeng 9 and Shuangchengnou in rice.
