The hydrogen plasma was excited by the technology of helicon-wave plasma chemical vapor deposition (HWP-CVD).
利用螺旋波等离子体化学气相沉积(HWP - CVD)技术，以氢气为反应气体产生等离子体。
But once a craft hits orbit, he says, his new invention makes more sense: The Mini-Helicon Plasma Thruster is designed to be a lighter, cheaper way to move through space.
但是一旦飞船进入太空轨道，他认为他的发明将会更具有现实意义：Mini—Helicon型等离子推进器正是为能更轻巧廉价地在太空飞行而诞生的。
