摘要：

CO//2 and N//2 jets issuing into air from small rectangular channels of 2 multiplied by 25 mm cross section were investigated. Concentration measurements were obtained by cw laser Raman spectroscopy. Gradients larger than 10 vol. %/100 mu m were resolved. Spatial resolution was better than 10** minus **2 mm**3 and the measured fluctuations of the Raman signals show satisfactory agreement with Poisson statistics. Axial and radial profiles are reported for single and multiple jets and comparison with theory is given, where possible.
