| 摘 要： | 电树与半结晶材料的形态结构有着密切的关系。在本文中，首先通过两种不同的热处理方式：（1）自然冷却，（2）急冷对高密度聚乙烯和低密度聚乙烯薄膜进行处理，然后，在不同的实验条件下测量电树的发展速度和长度。通过试验，我们发现尽管高密度聚乙烯比低密度聚乙烯有更高的结晶度和更大的球晶尺寸，并在电树起始阶段表现出高阻性，但电树在前者中的发展比在后者中容易。据此，我们推测，材料的形态结构对于电树的发生和电树的发展有着不同的影响。 |

| Abstract: | It is well known that electrical trees are nearly related to the morphology and structure in semi crystalline materials.In this paper,samples of low density polyethylene (LDPE) and high density polyethylene (HDPE) were disposed by two kinds of different ways:natural cooling down and quenching and formed the films finally.The growth rate and the length of electrical trees were measured under the various conditions.It is found that electrical tree growth in HDPE is easier than that in LDPE,even though there is high crystallinity and large spherulite size,HDPE shows high resistance to tree initiation.It is presumed that the morphology has different effects on the tree initiation and growth. |
| Keywords: | Electrical tree Morphology HDPE LDPE Heat treament Spherulite |
