Increase the compression degree can make arc of high temperature plasma jet extended, form more uniform high temperature area, and increase the speed of the jet, can reduce the width of the poor.

增加电弧的压缩程度可以使高温等离子射流延长，形成更为均匀的高温区域，同时加大射流的速度，可以减小切口上下的宽度差。

All particles reduce the jet velocity half-width, but the effects on the streamwise mean velocity profiles are complicated.

所有的颗粒都降低了射流速度半宽，但对流向平均速度剖面的影响比较复杂。

But researchers have come up with an effervescent solution: bubbles smaller than the width of a human hair can help reduce the costs of collecting algae oil.

但如今研究者们已找到了一个令人欢欣鼓舞的解决办法：使用小于人体毛发宽度的微小气泡可降低获取藻类油料所产生的成本。
