Abstract: This article selected lung cancer as the research object, which is easy to be objective and has a relatively high incidence. After the sample data was screened according to the research requirements, time domain analysis methods was used to identify the pulsation period.Then,discriminant analysis, modular identification were used to analyze the relevant data in combination with the specific characteristics of Jin’s pulse.Impulse stroke and its pulse characteristics were identified through experimental research. The corresponding relationship between the lung and the corresponding pulse points was verified by the performance of impulse stroke formed by lung cancer on the same points which was consistent with the perception of researcher Jin Wei. The result can be used as one of the early auxiliary diagnosis base for lung cancer and promote the study of pulse diagnosis.

Key words: Jin’s pulse theory, impulse stroke, space-occupying diseases, objectification, pulse signal analysis
