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.
