3DIGITAL GENERATION OF TWO-DIMENSIONAL FIELD OF TURBULENCE FOR FLIGHT SIMULATION显示文摘In some special cases of flight simulation (e.g. for formation flight, in-flight tanking) it is required to generate a two-dimensional field of turbulence, in which the turbulent wind speeds are stochastic functions of two coordinates (e.g. x in the flight direction and y in the wing span direction). For this purpose a simple and efficient technique for the digital generation of a two-dimensional field of turbulence,i.e. for the production of turbulent speed sequences on a rectangular network, is proposed in this paper. The correlation of the turbulent field so generated is found to be in good agreement with the theoretical correlation of the turbulence model, and thus the feasibility of the proposed method is verified. Two possible operation modes (off-line and on-line) of the turbulence generator in flight simulation are also discussed.Yelun, Xiao 1990Chinese Journal of Aeronautics1990,5,4:1
4Study on Compositions of Grain Starch and SGP-1 Protein in Black Grain Wheat显示文摘In view of the lack of wheat genetic resources with high amylose and high resistant starch contents in the present world,the grain starch components and SGP-1 (SGP-A1,SGP-B1 and SGP-D1) protein composition of 43 black-kernel wheat genetic resources such as Jizi 439 were identified by SDS-PAGE electrophoresis detection.The results showed that 11 materials were lack of SGP-A1,and no materials had SGP-B1 and SGP-D1 deletion.Seven materials were identified to have an amylose content more than 30% of the total starch.A total of 12 materials were selected for the determination of resistant starch content,and five materials were found to have a high resistant starch content.The above results lay a foundation for wheat breeding for high resistant starch content.Yaning MENG Qiaqia WANG Yelun ZHANG Suque LAN Guangwei LI Xingpu LI Dongyue GU 2019Agricultural Biotechnology2019,8,3:0
