The SrTiO_3 double function component is widely applied due to its excellent properties.

It was found that the microstructure and quality of the powder could be improved when pre-sintering temperature was 1 100 ℃,which could further improved the properties of varistor-capacitance double function components.

The development of doublefunctional ceramics and elements both at home and abroad was outlined, with emphasis on the operation mechanisms, processability and properties of SrTiO3.

The effect of combustion property of the coke using three different anions Ac -, Cl -, NO - 3 and three type of function elements alkali K + , alkaline earth Ca 2+ and transition metal Cu 2+ ions was studied in a coke combustion reactor.

The design methodology of entire life cycle based on parameter function unit is that function unit and features are used as information units to model and simulate products in order to increase the design speed and succeeded rate.

To achieve the innovative design most potentially and the settlement of function unit exactly,this paper builds function catalog of execution machines,builds integrative appraise system,takes the motion correspond relation between multi function units,achieves the seletion of execution machine by function indeed.
