平面電極放電圖形之分析及模擬

Abstract

我們歸納平面電極放電圖形的類型,然後分析圖形的碎形性質,發現放電 圖形具有碎形的幾何性質. 另外,我們簡單的假設放電機制, 再利用活性 行走模型(Active Walker Model 簡稱AWM)來模擬放電圖形. 從模擬的圖 形, 我們探討模擬圖形和參數間的定性關係. 並進一步和實驗放電圖形比 較. 可以確定模擬參數和實驗的物理條件之關係. Different types of experimental dielectric breakdown patterns are described in detail and examined using 'fractal' analysis. It is found that the patternsremarkbaly display fractal structure. Then, we applied the Active Walker Model(AWM) to study the possible physical mechanism of dielectric breakdown in liquid.The influence of model parameters on pattern growth behavior is examined. Varioustypes of computer simulation patterns are compared with experimental patterns,the relationship between the model parameters and the physical conditions during breakdown is also examined.
