它与一般的低密度聚乙烯不同，后者采用较不方便的高压过程生产。

This is in contrast to conventional LDPE which is produced by the somewhat less convenient high pressure process.

采用调制式DSC分别对热、拉伸及高压处理后低密度聚乙烯的聚集态结构变化特点作了研究。

The effects of heating, tensile and high pressure treatments on the aggregate structure of low density polyethylene (PE-LD) samples were studied using a modulated DSC (MDSC).
