Abstract: To clarify the quantitative relationships between physical parameters of cigarettes and guide the design of cigarettes of different specifications, the compositions and correlations of draw resistance and ventilation rates were analyzed based on the Darcy's Law. The model for the quantitative relationships between physical parameters of different cigarettes was established and verified. The results showed that: 1) The P values of the two-sample t-tests for the fitted and detected values of filter ventilation, paper ventilation, total ventilation and draw resistance were 0.943, 0.759, 0.984 and 0.844 respectively, and there was no significant difference. The Poisson correlation coefficients of paired two-sample t-tests were 0.999, 0.990, 0.999 and 0.993 respectively. The quantitative model was consistent with the actual experimental results and could be used to predict and design the physical indicators of cigarette products of different specifications. 2) The variables introduced in the process of modeling were general physical indicators of the test cigarettes, the equipment used were conventional cigarette physical parameter detection instruments, and the data was easy to detect and obtain, which was convenient for technicians to master and apply.
