In this paper,a uniform mathematical model of the algorithms based on spatial relations for feature matching is firstly Abstracted in theory;and then the shortcomings of various global consistency measure criterions are anatomized in detail,which defined by a few existing classical methods;finally,a new one is proposed to overcome their shortcomings.

On the basis of a thorough analysis of the methods of declaration and accessing to the static data member in C++ language,authors point out the abuse of utilizing global variable to implement the shared data in program design,and at the same time give out the ways how a static data member replaces the global variable and questions to be paid attention to in using static data member.

The article starts from discussing the concept of global variable in C#,extends to the definition and usage of global used variables with detailed analysis and explanations from different angle and level.

In advanced language program, the side effect of the subprogram is referred that the subprogram (procedure or function) change public variable or no local variable.

Based on random sets theory,false alarms and miss-detections in the background were considered,then,belief measure and its global density of targets were presented.

The HowU grid system used the hierarchical resource management of grid resource and its grid global scheduling.

Based on constraint satisfaction problems model a global scheduling module structure is designed.
