Considering the characteristic of development of GIS technology,this article presents a method for GIS analysis and design,which is metafunction_oriented.

As one kernel idea of Systemic Functional Grammar which has greatly influenced linguistics in the late twentieth century,metafunction has undergone a process of development and improvement.

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.
