Over the weekend, physicists began circulating beams of protons around the 27-kilometre ring of the Large Hadron Collider (LHC) at CERN, Europe's particle-physics laboratory near Geneva, Switzerland.
By considering the effects of gas velocity and particlecirculating rate on the surface abrasion rate, an empirical equation is proposed.
实验结果揭示了气体流速和固体颗粒循环速率两个操作条件对磨损速率的影响规律。

Cyclone separators are the key equipment for warranting that circulating fluidized bed boilers have a certain particle circulation rate, with good combustion and desulfurization efficiency.
