摘　　要：目的:通过研究桌面不同供氧位置和氧气射流角度对坐姿工作呼吸区弥散富氧效果的影响,验证局部弥散富氧的可行性。方法:通过检测桌面不同供氧终端位置及氧气射流角度条件下坐姿工作呼吸区的氧浓度分布,比较不同初始条件对吸入区氧浓度提升率的影响。结果:不同桌面供氧位置和氧气射流角度对吸入区氧浓度提升率产生不同影响。结论:通过调整不同初始条件可以实现坐姿工作呼吸区局部弥散富氧。Objective:To verify the feasibility of local diffusion oxygen enrichment by studying the effects of different oxygen supply positions and oxygen jet angles on the desktop on the working breathing zone in sitting position.Methods:The effects of different initial conditions on the increase rate of oxygen concentration in the suction zone were compared by detecting the oxygen concentration distribution in the working breathing zone in sitting position under different oxygen supply terminal positions and oxygen jet angles on the desktop.Results:Different oxygen supply positions and oxygen jet angles had different effects on the increase rate of oxygen concentration in the suction zone on the desktop.Conclusion:By adjusting different initial conditions,local diffusion oxygen enrichment in the working breathing zone in sitting position can be achieved.
