采用脉冲激光烧蚀技术在氩气环境下制备了纳米硅薄膜，研究了环境气体压强对纳米硅薄膜表面形貌的影响。
In argon (ar) gas, nanocrystalline silicon films are prepared by pulsed laser ablation. The influence of ambient pressure on surface morphology of nanocrystalline silicon film is studied.
由于其激光工作介质是气体，而且激光腔内的压力与外界环境压强相差很大，激光束的输出窗口必须密封。
Because the working media of laser is gas, and the pressure difference between the inner apparatus and environment of laser is large, so the window of output laser beam must be sealed.
通过低压强风试验舱模拟珠峰环境，对火种灯炭柱的燃烧气体产物进行了测定。
The gas-products of Olympic kindling spark were studied in simulation test module, with strong wind and low pressure which like natural environment of Jolmo Lungma.
