| 摘 要： | 由于超临界流体温度和压力较高，用于测量其折射率的光学池需要特殊设计。超临界流体(Super Critical Fluid，SCF)光学池设计为细长形体，以便控温和耐高压；光屏两点投射法测量超临界流体折射率应采用斜交光学池；分析了斜交光学池测量折射率的光路，推出了斜交光学池平行窗口和非平行窗口光路计算的方程，并给出了求解折射率的方法。

| Abstract: | The optical cell of supercritical fluid is designed to be small diameter cylinder to sustain high pressure, and be long to arrange the device to control temperature. The optical cell with inclined windows is easily applied to measure the refractive index of supercritical fluid according to the method of two projecting point on screen. The paper analyses the optical paths of the inclined cell, develops the equations to describe the optical paths of parallel windows of the inclined cell, and points out that the refractive index could be obtained by programming and solving the equations numerically. |
