利用带有不同拓扑荷数的两束涡旋光束进行共轴叠加，产生了一种新型光束双涡旋光束，其光强分布为双环结构。

A new type of the double-vortex beam is generated by the coaxial superposition of vortex beams with two different topological charges, whose intensity distribution is double-ring.

由此提出了一种新型轴向柔性涡旋压缩机结构，此结构具有能够进行双调节的两个背压室。

So this paper put forword a new type axial compliant mechanism scroll compressor , this compressor has two double temper back pressure chamber.
