From the perspective of forming homogeneous premixed gas and having well chemical reaction kinetics effect after ignition,comparison experiments of different approaches which can achieve HCCI(homogeneous charge compression ignition) combustion mode were carried out on a 135 single-cylinder diesel engine with double contract annular chamber,P-pump,pro-injection mode,conical spray nozzle and emulsified oil and diesohol.
In according with Arrhenius experience formula of relationship of reaction velocity and temperature in the chemical reaction dynamics, technically reaction velocity was turned in to temperature variation, experimental activation energy of well distributed particles(0.22～0.45mm) anthracite volatimatter ignite were measured.
The theoretical model of chemical reaction dynamics is used to simulate the reaction process, and the reaction activation energy, the reaction rate constant and the reaction rate equation are obtained.
The mathematical model was established on the basis of chemical reaction dynamics and the practical process data of 50 kt/a plasticizer unit and was proved using a number of data. Theory basis for capacity expansion of the 50 kt/a plasticizer unit was provided.
Chemical kinetics calculation and experimental research were used to find out the mechanism between N2O and N-agent species, N-agent/NO nitrogen stoichiometric ratio (NSR), reaction temperature, reaction time, etc.
The seven kinetic parameters of the calibrated model are determined using a combination of the Micro-Genetic Algorithm and the SENKIN program of CHEMKIN chemical kinetics software package.
It was demonstrated that simulation of thermal aging of canned fish on the basis of on the laws of chemical kinetics may be used for predicting quality changes and determining shelf life.

Moreover, to date the chemical kinetics have received little study, and there are simply no reliable data that can be used in the calculations.
