研究发现随着乙烯分子浓度的增加，被吸附的乙烯分子之间相互作用能随之增加，而乙烯分子的总扩散系数随浓度增加而单调递减。
It was found that the interactions between ethene molecules increase with the increasing of molecular concentration, while molecular total self-diffusion coefficient decreases with the concentration.
链节之间的相互作用能量参数由粘度的关联式获得，其它四个参数则由扩散系数的实验数据获得。
The segment-segment interaction energy parameter was obtained from the viscosity correlation, and the other four parameters were determined from the experimental diffusion data.
