Abstract : with an optical probe based on the principle of multi - wavelength light extinction , size and concentration of droplet were measured in a transonic wind tunnel . this paper presents the measurement results 文摘:应用基于多波长消光法原理发展的光学探针，测量了跨声速风洞中不同马赫数湿空气流自发凝结形成的水滴尺寸及浓度，并给出了实验结果。
By using the new method of variable separation with addition , semi - analytical solutions of 2 - dimensional ( 2 - d ) steady incompressible viscous gas diffusion flow field are obtained in the paper , and suitable conditions are discussed 摘要运用加法分离变量法，解析求解了二维定常粘性气体不可压缩扩散流场，得到了几组空气流场有源汇和无源汇情况下扩散流场的半解析解，并分析了其适用条件。
For pcr product analysis area or last area of three areas ( area for amplification and product analysis ) , direction of air flow shall be from outside to inside of the area by setting up fume hood , exhaust fan or other exhaust system in the area 产物分析区或三个区域的最后一个区域（即扩增及产物分析区） ，空气流向应由室外向室内，可通过在室内设置通风橱、排风扇或其他排风系统达到空气流由室外向室内流动的要求。
It is shown that when the exit area of secondary nozzle and the fuel / oxidizer ratio is fixed , the increase of mass flow rate of secondary flow lead to the decrease of velocity of mixed flow , and increase of total mass flow rate . the synthetical result of these two phenomenon cause the increase of thrust of rocket ejector , but the increasing magnitude is relatively small , indicating that these is no necessary to claim large bypass ratio in rocket ejector design . in the comparison between two configurations , the typical one has better performance , indicating the importance of pressure ratio 结果表明：在固定二次喷管出口面积和氧燃比的条件下，二次流(引射空气流)流量的增加引起混合气体出口速度的下降和总流量的增加，二者综合作用使发动机推力增加，但增幅不大，表明在设计发动机结构和工作参数时，不必过分追求大的引射系数；两种结构的性能对比分析表明了增压比对引射火箭性能的提高具有重要意义；对引射火箭的热力循环分析同样表明，增压比对于提高发动机性能非常关键。
While the speed is very large , the fuel - air mixing behind the airstream is decreased and the span that the fuel flow in the second combustor is reduced , so the combustion efficiency is decreased , h ) if the fuel streams impinge with the airstreams directly at the air - inlet exit , it make against increasing the combustion efficiency , i ) increasing air - to - fuel ratio within proper range can increase the combustion efficiency 增加燃气喷射速度有利于增强回流区强度，头部燃烧温度上升，但速度太大则会减弱燃气同空气在进气道下游的掺混燃烧，减少燃气在室内停留时间，燃烧效率降低； 8燃气射流与空气流在进气道出口直接撞击不利于燃烧效率的提高； 9在适当范围内增大空燃比能显著提高燃烧效率。
