In this paper,we show the significant of the new mathematics theory of two variables system ([3]) and some main concept on the classification of the new mathematics theory of two variables system.

Via reading system variables fixed point of axes can be determined in machine coordinates system: Via reading system variables PLC state bit is condition of criterion as NC macro-program goto;Via transferring positioning function FC15 or FC18 control for PLC axis is finished.

Boiling process under different condition were taken pictures depending on the use of microscopy in order to find how system variables such as surface condition, laser parameters effect the rapid transient explosive boiling under low temperature environment.

The studies of the witness from the psychologist s view have had two ways of estimator variables and system variables and much achievement.

Using system variable to design high quality physic virtual experiment;

In this paper the cutter radius compensation is set up by the function of using the macro program to evaluate the system variable,it discusses daisy chain incise method for slot and gibbous platform NC process which the section is Monotone curve.

This article introduces the development of eyewitness identification in the west, analyzes estimator variables and system variables that influence the performance of eyewitness identification, and then discusses the problems of theory relevant and external validity.

On the basis of the processing,we also have a comparison with bavariate statistics.
