It was found that the gas temperatures at arc root and arc tip are equal and they decrease with the argon flow rate increasing.
实验发现弧根和弧梢处的气体温度相等，并随着气体流量的增大而下降。
With gas flow rate increasing, the vibrational temperature at both tip and root decreases, but the decreasing rate at arc tip is faster than that at arc root.
随着气体流量的增大，弧梢处与弧根处的振动温度均下降，但弧梢处下降速率较快。
The results show that the number of OH radicals decreases rapidly and the number of o atoms follows a rule of increasing firstly and then decreasing from arc root to arc tip.
结果表明：沿等离子体从弧根到弧梢位置，OH自由基数量迅速减少，O原子数量呈现先增多后减少的规律。
According to the analysis of the applied forces on the molten poor at arc root the theoretical function in which the arc erosion of metal droplet ejection can be characterized was founded.
根据旋弧弧根处熔化液池的受力分析，在理论上建立了能描述旋弧喷溅侵蚀特性的函数关系式。此理论关系表明，在无外磁场作用下，液池中心受力最大，将形成中心喷溅；
