Abstract:The gas permeability coefficients of different material films at 2,4,8 and 20 ℃ were measured by small bags method. The influences of temperature on the gas permeability coefficient and gas permeability coefficient ratio were analyzed. The results suggested that the gas permeability coefficients of films increases with temperature; as the temperature increased, the gas permeability coefficient ratio of LDPE significantly increases, while the gas permeability coefficient ratio of PVC shows different changing trends at the experimental temperature. The relationship between permeability coefficients and temperature well accords with Arrhenius equation, and a linear relationship lies between nature logarithmic of gas permeability coefficient and the reciprocal of temperature. |
Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
