Example Sentences:

	1.	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。
	2.	Abstract : optimum distances between primary nozzle exit and mixing tube inlet , static pressure recovery of the mixing flow in mixing tube 、 total pressure distributions at the exit of mixing tube 、 pumping coefficients and total pressure losses of the exhaust ejector systems with four different types of primary nozzles have been measured in the experiments 文摘:对4种主喷管组成的排气引射系统的引射系数和总压损失、各主喷管出口与混合管进口之间的最佳间距、混合气流在混合管内的静压恢复及混合气流在混合管出口处的总压分布等进行了测量和对比。
	3.	The experimental results indicates that the secondary mass flow increases with increasing of primary mass flow rate , but the bypass decrease because the primary mass flow rate increase more rapidly than secondary mass flow . the expansion configuration shows low thrust property due to low pressure in flow path . the secondary nozzle changes the pressure distribution in ejector combustor , and decreases bypass ratio , but obtain more completely mixing 结果表明：二次流流量随着一次流流量的增加而增加，由于二次流流量的增加速度低于一次流，引射系数减小；在纯扩张式结构实验中，引射燃烧室压强很低，难以实验推力增强；二次喷管改变了引射燃烧室的压强分布，降低了引射系数，改善了混合状况能；对于本文的实验结构，存在一个最优的二次喷管出口面积，使引射火箭推力最大，同数值模拟结果相吻合。
