Studies on the cigarette hardness(II) The Influence of relative humidity, temperature and net weight on cigarette hardness

담배 경도에 관한 연구(II) 상대습도, 온도 및 진충량이 담배의 경도에 미치는 영향

This experiment carried out to review influence of relative humidity, temperature and net weight on cigarette hardness for the uniformal control of cigarette quality. Obtained results are as follows: 1. The difference in the cigarette physical properties of constant hardness control is considerably lower than that of constant net weight control. 2. Contribution rate for cigarette hardness is relative humidity > net weight > temperature. 3. The multiple regression equation of cigarette hardness related with relative humidity, temperature and net weight is calculated as follows.
