摘要
开发了一种可用于测定多相流动体系内气泡特性的抗撞击的电导探针，核电导探针可测到的最小气泡直径约为１．０ｍｍ。在三维三相流化床中利用照相法对电导探针进行了标定，得到了气泡刺穿长度与气泡Ｓａｕｔｅｒ直径的关系式。
An anti-dashed conductivity microprobe was developed to measure bubble properties inamuItiphase flow system. The minimum bubble size detectable with the microprobe is ap-proximately 1.0mm. The calibration of the microprobe was performed with a photographicmethod in a three-dimensional three-phase fluidized bed,and the relationship between bubblepiercing length and bubble Sauter diameter was given.
