Methods First, 704 patients receiving CO2 laryngeal laser operation from July 2, 2003 to August 21, 2008 were enrolled, and their risk events and causes were systematically analyzed. Second, in vitro experiment, we tested the tolerance of the PVC tube against different CO2 laser energy in different cutting patterns when the cuff was inflated in water or air. We also tested the combustion conditions of the PVC tube in different oxygen concentration, laser energy and cutting patterns. Results Tracheal cuff were punctured by the laser in 92 of all 704 cases. Spark and dense smoke were observed in 8 and 37 cases respectively.

The computational results indicate that surface catalytic combustion restrains gas phase combustion. Inlet velocity and tube diameters have important influence on catalytic combustion of hydrogen. For smaller inlet velocities,reaction is dominated by gas phase combustion. As the inlet velocity increases,there exist both surface catalytic combustion and gas phase combustion. For bigger inlet velocities,reaction is dominated by surface catalytic combustion. The temperature of flame core decreases with the decrease of tube diameter.

计算结果表明，表面催化反应对空间气相反应有抑制作用；入口速度和管径对氢气的催化燃烧过程有重要的影响，在入口速度较小时，燃烧主要是空间气相化学反应，随着入口速度的增大，燃烧过程同时存在着表面催化反应和空间气相反应两种控制因素，在入口速度较大时，燃烧主要是表面催化燃烧过程；随着管径的减小，微型管道内反应的最高温度降低。

A method and apparatus for increasing the propelling force of pulse engine features that the fuel nozzle of pulse explosion engine is arranged in combustion chamber to close jet tube exit, and the fuel is reversely sprayed out to generate a shock wave barrier near the jet tube for preventing the airflow from flowing out of the combustion chamber, resulting in raising the pressure in combustion chamber and in turn increasing the propelling force.

本发明公开了一种提高脉冲发动机推力的方法和装置，它是通过将脉冲爆轰发动机的燃料嘴置放在燃烧室中靠近喷管出口附近，并使燃料逆向喷出，在燃烧室内靠近喷管附近形成一道阻止气流流出燃烧室的激波，激波的作用是使燃烧室压力升高，从而的到较大的推力。同时由于本发明的结构特别的简单，所以实现非常容易，并且工作效果十分显著。
