The authors compare the behaviors of space charge in dried and undried low density polyethylene and which doped with 0.5% Al_2O_3 powder via infrared spectrum method, thermogravimetry and the Pressure Wave Propagationmethod, and the water content is quantitatively measured.

作者通过红外吸收光谱法、热重分析法和压力波法，分别对低密度聚乙烯以及以0.5%Al2O3粉末掺杂的低密度聚乙烯在干燥前后的有关空间电荷行为进行了比较，定量给出水份含量和对应的空间电荷特性。

Firstly, indoor rheological research was done on the transportation oil of Dongxin pipeline. Then, 5 kind antifreezing agents and 5 kind viscosity reducers were selected based on the rheological characteristic.. EVA(2804) antifreezing agent with better modifying effect was chosen, and its modifying effect was certified by the indoor annulus experiment: the freezing point of Dongxin crude oil can be reduced to 5℃, and the viscosity reducing rate can be up to 9.51%.

首先对东辛线输送介质进行了室内流变性研究，然后根据其流变特性查阅文献选取了5种降凝剂和5种降粘剂，分别测定了原油加剂前后的凝点和表观粘度的变化，最终筛选出了一种改性效果最好的药剂，并通过室内环道实验验证了改性效果。
