We measured the edge response function with used CCD,and carried on the Gauss curve fitting after the first order difference,thus obtained the point spread function of optical system.

In this paper, a definition of quasi-Gauss-Kronecker curvature is given and the characterizations of hypersurfaces with constant quasi-Gauss-Kronecker curvature in S4(1) are studied.

This paper deduces the formulas about capacitance and voltage when the pretilt angle isn't zero, and presents the method to determine the elastic constants k11 and k33 simultaneously by curve-fitting.

The paper use the method of curve regression to calculate the public flow, solving the ploblem in counting total flow.

4 kg, 15 kgand 42 kg of TNT and rock emulsion explosives were respectively measured, and their pressurescaled distance relations consistent with the experiment results were also obtained by curve regression.

It can decrease the sample rate and the power by polyphase decomposition method;and modify frequency response characteristics by using curve regression technology.
