摘要：

In this paper it is shown that the Mayr-type are models can be used to describe the are behavior before current zero exactly. Based on this analysis the different types of 'modified' Mayr are models can be explained. As a result of the theory, an improved Mayr-type are model - with a constant time parameter and a cooling power which is dependent on the electrical power input - is introduced and used to reproduce current zero measurements successfully.
