ethylene polymers造句

• Standard test method for dilute solution viscosity of ethylene polymers
  乙烯聚合物稀溶液粘度的标准试验方法
• The method using an improved osmotic membrane f46 ( made by ethylene polymer ) to separate gases from oil is brought forward . capability of osmotic membrane f46 is discussed too . from a great of experimentations, we get the osmotic balance curve of gases, confirm balance conversion coefficient
  2)研究以高分子透气膜为特征的变压器油在线脱气技术；提出了一种能有效改进气体渗透性能的聚四氟乙烯和六氟乙烯的混合膜（f46膜）用于变压器油气自动分离，分析f46膜的气体渗透性能，通过大量的试验得出气体渗透平衡曲线，确定油中气体的平衡转换系数，为实施变压器油中气体在线监测奠定基础。
