The results show that, the gas pressure, electrical current, and the virtual breadth of the annularelectrode affect the radial distribution of the plasma density and temperature.
结果表明，放电气压、电流以及环电极的有效宽度均影响等离子体密度和温度的径向分布。

But the lessening of virtual breadth of the annularelectrode makes the radial distribution of plasma density more unequal, and the total density and the average temperature lower.
但环电极有效宽度的减小使得等离子体密度的分布更不均匀，并使总的密度和平均温度均下降。
