摘要

本文给出了三层介质发散场的树起始时间(/spl tau//sub i/)的实验结果。结果表明，高介电常数介电势垒的应用可能会大大增加树起始时间。确定了树起始时间与绝缘间隙中的屏障位置有关，在最优屏障位置处树起始时间最大。这样，树的起始长度(l/sub i/)在这个屏障位置具有最小值。局部场非均匀性系数与起始树时间和起始树长度吻合较好。

Tree-inception in the three-layer dielectrics

The experimental results of study of the tree-inception time (/spl tau//sub i/) in the divergent field for the three-layer dielectrics are presented in this paper. It is shown that the tree-inception time may be essential increased due to the application of dielectric barriers with high permittivity. It is determined that the tree-inception time depends on the barrier position in the insulating gap and it has a maximum at the optimal barrier position. In doing so, the tree-inception length (l/sub i/) has a minimum value at this barrier position. Good agreement between the coefficient of the local field nonuniformity and the tree-inception time or the tree-inception length was found.
