【Abstract】 The determination of potentiometric titration end-points in analytical chemistry filed by using the mathematic method has been got more and more attention with the rapid development of computer technology.Based on the multi-resolution analysis and the wavelet singularity detection theory,a new method with the module maximum of the detail coefficient reconstruction signal in low scales is presented .The method operate simply and has high precision with the right wavelet function.The result of experiment dates also prove its feasibility.更多还原
