Regression by the Level of Signal in the Quantitative Qnalysis of Physics and Chemistry

Objective To establish a method of regression computation by the level of signal.Methods Write a programme to make computer regress by selecting the standard signals matching the level of the signal to be determined according to the programme and computing the content of substance unknown。Results Compare with full access regression,regression analysis by the level of signal will have much more chances make the result approach to the true value.Conclusions By the computer and the programme to be written,regression by the level of signal realize a intelligentized computing mode for regression.
