磁场使得这种向外流动形成螺旋状轨道，微粒就被这些离子带动而形成螺旋状条纹。
The magnetic field turns this outward flow into spiral-shaped orbits, and the microparticles become swept along by these ions and pushed into vortices around the filaments.
螺旋线(气道)位于切向气道的上游，以使来自螺旋线外流的恶化减至最小，并获得切向气道气流的最佳支持。
Helical line (port) is in upstream of tangential port, minimizes the deterioration came from outflow of helical line, and obtains the best support of tangential port airflow.
研制了由内向外流动的螺旋通道微流控PCR玻璃芯片，减少了PCR反应液在微通道中流动时的分散和阻力；
A spiral-channel flow-through PCR microchip reactor with 35 cycles, which reduced the dispersion and flow resistance of reaction solution, has been developed.
