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.

function-unit,which is a basic unit to complete some especial functions,is a realization unit of the corresponding function.

Research on information management platform of networked technical equipments based on functional unit;

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.

Halliday believes that language has three meta-functions——ideational,interpersonal and textual.

Considering reliability information modeling as a key technology in CNC(Computerized Numerical Control) machine tool reliability information system, the function element method, a kind of new CNC machine tool reliability information modeling method, is proposed.
