2次元シリコーンゴム中に発生する交流トリーの進展と消失

抄録

The development mode of the AC tree can be classified into three modes; (i) straight mode, (ii) isotropic mode and (iii) selected branch mode. The development of the tree in diffusion mode means that an envelope of the tips of the branches spreads as diffusion. This development has been considered. An AC tree in silicone rubber sample has disappeared after applied voltage. Behavior of the disappearance of trees is different in 2-dimensional (2-D) and 3-dimensional (3-D) sample in which needle electrode system was set up. The branches of 2-D tree are survived longer than the branches of the 3-D tree.
