| 1 | A rapid approach to convective aeroheating prediction of hypersonic vehicles显示文摘A rapid approach to hypersonic aeroheating predictions in the stagnation region and downstream is developed in the present paper.The engineering method is used to calculate inviscid hypersonic flowfields to reduce time cost,and a combination of the mass flow balance technique and the axisymmetric analog is proposed to account for the entropy swallowing effects.A three-dimensional linear method is derived to fit the vehicle surface flowfields.Then a new axisymmetric analog method based on linear flowfields and linear surface equations is developed,with the complexity and computational cost reduced dramatically.In the stagnation region,an implicit surface fitting is introduced to approximate the primary curvatures and a robust aeroheating prediction method is constructed.The proposed approach is verified on a variety of configurations including spherically blunted cone,double ellipsoid and aerospace vehicle.Numerical results indicate the followings:1)The approach predicts aeroheating in about one second and the results agree well with CFD simulations and wind-tunnel measurements;2)with the help of entropy correction,the precision is further improved in the streamline diverging regions on the vehicle surface,while little improvement is found after entropy correction in the regions where the streamlines do not diverge. | ZHAO JiSong GU LiangXian MA HongZhong | 2013 | Science China(Technological Sciences)2013，56，8： | 11 |

| 6 | Breeding of High-Yield Salinomycin-Producing Streptomyces albus Strains by Low Energy N^+ Ion Beam Irradiation显示文摘[Objective] This study aimed to explore the mutagenesis effects of N+ ion beam implantation on Streptomyces albus and obtain high-yield salinomycin-producing mutant strain. [Method] Streptomyces albus strain S-11-04 was mutated with different doses of N+ implantation. The effects of low energy N+ implantation on the survival rate, colony morphology and salinomycin-producing ability were investigated. [Result] The results showed that low energy N+ implantation can efficiently improve the positive mutation rate of Streptomyces albus; 13 mutant strains with high yield of salinomycin were isolated; to be specific, mutant strain N3-6 has relatively good genetic stability with four continuous generations, and the titres of salinomycin were increased by 41% in the shake-flask culture and 20.5% in mass production compared with the control. [Conclusion] N+ ion beam irradiation is an effective method to obtain high-yield salinomycin-producing Streptomyces albus strain. | Liqin WU Fengxiang MIAO Haike GU Hongzhong SHANG | 2012 | Agricultural Biotechnology2012，1，5： | 0 |
