The maximum penetration depth of gas flow is increased with the increase of gas momentum while the diameter of oxigen gunjet keeps constant.

气流的最大穿透深度随气体动量的增加而增加，而氧气喷枪的直径保持恒定。

Early jet engines had narrow inlets and were very noisy, but as the diameter of the fans at the front increased, the engines became quieter.

早期的喷气式发动机进气口狭窄且噪音巨大但是随着前部风扇直径的增大发动机变得越来越安静。

In addition, plasma jet from the form into consideration, the jet from the gun in diameter is expands outward, nozzle increase in altitude inevitably lead to increased width incision.

另外，从等离子射流的形态方面考虑，射流直径在离开枪口后是向外膨胀的，喷嘴高度的增加必然引起切口宽度加大。

Also adding to the nostalgia of using an old-fashioned number two is the larger rubber tip, slightly bigger diameter (8mm) and increased length of the pen itself.
