| 1 | 涡轮级轮缘封严内非定常流场的准三维LDV测量显示文摘研究涡轮级封严内流动和主流的相互作用、相互影响,进一步认识盘腔内燃气入侵等非定常现象,急需流场实验数据验证。针对轮缘封严内空间狭窄、光路安排困难等问题,本文发展了一种用于测量涡轮级轮缘封严内非定常流场的准三维LDV技术,即测量分两步,首先在机匣上安置二维测速系统用符合方式测出径向、切向速度及湍流度,再在轮毂内安置一维探头重复测量,从两次测量数据中计算出轴向速度;该技术借助锁相采样等技术能测出不同动静叶相对位置情况下封严及盘腔内的周期性非定常流场细节,本文给出了部分典型的动态流场测量结果。 | 马宏伟 Dieter E Bohn Achim Decker Bernd Rudzinski | 2004 | 航空动力学报2004，19，4： | 14 |
| 2 | N_2O emissions from agricultural soils in the North China Plain: the effect of chemical nitrogen fertilizer and organic manure显示文摘An enclosed chamber technique was used to measure N 2O emissions from intensively agricultural soils of the North China Plain during the periods of 1995—1996 and 1997—1998, to reflect distinct components of winter wheat and summer maize growing seasons. The results showed that the continuous application of fertilizer in agricultural soils increased N\-2O emissions by a factor of 24.1—28.1, the calculated annual chemical N fertilizer\|transformed N\-2O\|N emissions was 0.67%. Our results indicated that the application of organic manure also had a significant influence on soil N 2O emissions, which combined with the use of chemical N increased about 20% in a year. It was calculated that there were about 0.11% N of organic manure transformed as N 2O N. Annual mean N 2O emission from our study area of fertilized soils was estimated to be 57.1 μgN 2O/(m 2·h). A weak correlation was also found between N 2O emissions and soil available nitrogen content NH + 4. | DONG Yun\|she 1,2,3 , Dieter Scharffe 2, Manfred Domroes 3, QI Yu chun 1, ZHANG Shen 1 (1.
