The roles of temperature in Daqu preparation and in practical production were studied and the function relation between and liquor-making was obtained by the use of mathematic instrument.

The research results show that the function relation exists between devolatilization percentage and temperature, which provides theoretical foundations for the further studies of the biomass flash pyrolysis liquefaction.

The function relation between the dilating velocity and the nuclear exploding yield was set up.

Analyzing with coefficient of correlation, no obvious correlation was found between the hibernant larva density and the harm level of 1st generation of Asian corn borer (ACB) in Baoding, Hengshui, Ningjin, Langfang, and Zhangjikou city of Hebei province.

Blind Source Separation(BSS) technology can improve signal to noise ratio in receiver,this paper presents a approach of improvement for the performance of Infomax algorithm by training sequence in communications,and gives simulation based on coefficient of correlation and performance index(PI),simulation results shows that the approach can enhance SNR and the conve.

This article introduced the concept and properties of coefficient of correlation, and offered three methods of proving the properties.

Tree-based compensation of correlation coefficients for full covariance modeling;

Reliability sensitivity to the correlation coefficients among random variables;

Stochastic resonance based on correlation coefficient in parallel array of threshold devices;
