摘　　要：流化床催化反应过程、煤的流化床燃烧与气化等多种流化床工业应用都涉及高温操作。文中结合研究结果 ,综述了温度对最小流化速度、最小流化空隙率、床层膨胀比和气泡直径的影响。在前人研究的基础上 。The catalytic reaction process in fluidized beds, the coal combustion and gasification in the bed, and other various industrial processes all involve high temperature operation. It focuses on reviewing the effect of temperature on the minimum fluidization velocity, minimum fluidization voidage, bed expansion ratio, and bubble diameter, which are in relation with the design and operation of fluidized beds. Based on experimental findings and theory research of author and other researchers, some suggestions are proposed on the fundamental studies at the high temperature fluidized beds.
