中文摘要:通过小袋法测定了不同材料薄膜分别在2、8、14、20℃下的薄膜透气系数,分析了温度对薄膜透气系数和透气系数比的影响。试验得出:随着温度的升高果蔬包装薄膜的透气系数增大,薄膜材料LDPE的透气系数比显著上升,但薄膜材料PVC的透气系数比在试验温度范围内呈现不同的变化趋势。薄膜透气系数与绝对温度之间满足Arrhenius方程,透气系数的自然对数值与绝对温度的倒数值之间呈显著的线性关系。

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.
