To provide some form of throttle to allow acceleration and deceleration, the vehicle’s designers added the EJ200 jet engine.

为提供某种节流阀以加速或减速，该车的设计者们增加了“EJ200”喷气式发动机。

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。

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。

This is no comfort as the forecasts continue to be grim, but it is a measure of the complexity of the physics involved - how air moves in waves, why certain patterns form - that more than 60 years later scientists are still wrestling with the question of how the jet stream operates and what shapes it.
