This paper presents the application of gamma ray scanning technique to distillation/absorption columns and FCC risers.The flow regime transition.clear liquid height,froth height.crestliquid height over the exit weir on a V-1 type valve tray and downcomer hydraulics were investigatedusing the scanning device previously developed.The solid distribution and coke deposition were experi-mentally simulated in a FCC riser simulator by employing a three dimensional scanning device devel-oped for the present investigation.The success of this investigation should shed a light forquantifying two-phase contact phenomena in various gas liquid and gas solid two phase flow system.

P ̄(53)基因简介P53是一种细胞核磷蛋白,1979年发现于SV40转化细胞的抽提物中,它的质量为53kD(千道尔顿),由375个氨基酸组成,并被证明是由一种细胞基因所编码的,故称该基因为P53基因。经分析P53基因定位于17P,基因全长约
用放射免疫分析法对两组不同年龄的正常人血浆精氨酸加压素含量进行了观察。结果表明,中老年组显著高于青年组(P<0.01),男女比较无显著差异(P>0.05).提示血浆精氨酸加压素含量处于较高水平可能为
