Two combinatorial structures of regular and weightable independent systems were established based on the general cases of multi-key problems.

Let (E,I) be an independent system with rank r.

Through proving, it is draw the conclusion that deduction of SFP is tenable strictly in the intertia reference system of N objects independent system, and on the basis of this, the common formula of the deduction of SFP in non-inertia system of N objects independent system, and the extending formula in non-inerti.

Fresh Water Fish Fauna and Zoogeography of Six Substantive Rivers in the Coastal Area of Westen Mainland of South China;

Self is the core problem in the study of social cognitive neuroscience,and the system independency of self-cognition processing is increasingly accepted,but current research on behavioral experiment and fMRI is not enough to make the conclusion of the system independency of self-cognition processing.

Research about independent coordinate system conversion from Gaussian coordinate system

The process of establishing independent coordinate system in JiYuan City is introduced,the calculation method of the ellipsoid parameter of this system is disussed,the relation of conversioning independent coordinate system to National Coordinate System is carried out.

When a independent coordinate system is not built up strictly according to the survey specification, there are linear conversion and Gauss projection calculation to convert projection zone in converting interactively coordinates from the independent coordinate system to Beijing Geodetic Coordinate System 1954.
