Because of its much larger external surface area and much smaller pore diameter than granular carriers, it is expected to benefit diffusion-controlled fast surfacereactions.
There were a lot of high energy ions in the sheath area, beside the surfacereactions, the surface of particulates could be etched by the ions, and the passivation effect would be eliminated.
在鞘层内存在大量高能离子，除表面反应外，离子还能对粉粒表面进行刻蚀，因此钝化效应将消失。

The core of the sun - where nuclear reactions produce neutrinos - apparently spins more slowly than the surface we see.
