本文报道了在原子能研究所1.2米回旋加速器上用26MeV的α粒子流轰击天然丰度的锑靶,通过~(121)Sb(α,2n)~(123)I反应,以铜基铂吸附剂对碘选择性吸附法分离和浓集~(123)I,制得Na~(123)I溶液。Na~(123)I的放化纯度大于99％。在辐照结束时,其主要放射性杂质~(124)I占产品~(123)I的比率小于1.4％,整个分离过程不到4小时即可完成,总的化学收率在95％以上。所得产品用冠醚为溶剂,对肾上腺显影剂6-碘甲基-19-去甲胆固醇以及心脏显影剂ω-~(123)I-十七烷酸进行了快速标记。结果表明,与国内外现用的标记方法相比较,该法具有快速、简便、产额高等优点。     

The aeroelastic effects on the scatter phenomenon of wind-tunnel data

The unsteady Reynolds-averaged Navier-Stokes equations coupled with the k SST turbulence model are solved to obtain the steady and unsteady aerodynamic forces for airfoils and wings.The effects of vibration types and amplitudes on aerodynamic forces of airfoils and wings are studied.The deformation characteristics of a swept wing induced by steady aerodynamic load are presented.It is found that for a vibrating elastic wing at small and medium incidences,its mean aerodynamic loads are almost the same as those obtained from the static one.On the contrary,at high incidences especially around the stall incidence,the vibration may change the mean values.In addition,the larger amplitude is,the larger discrepancy will be.For a swept wing,the steady aerodynamic loads usually lead to the "pitching down" effect on the wing tip which delays the stall compared with a rigid one;But this phenomenon dose not occur on a aeroelastic wing which can induce the separation ahead and trigger the stall.The above conclusions are in good agreement with the scatter characteristics of wind-tunnel data.The reason why the data obtained from wind tunnel and CFD are different is also analyzed.Meanwhile,it can be an explanation for scatter phenomenon of wind-tunnel data,especially for high incidence cases,which remains a puzzle so far.     

Experimental study of hypervapotron under conditions of high heat flux

In the light of the needs to develop high-performance heat transfer component for nation-level large-scale scientific projects of China,a hypervapotron experimental platform with supply of heat flux 1 10 MW m-2 was established.With this platform,the multiphase flow and heat transfer phenomena on the surface of triangular fin when the subcooled water flowed through were observed and measured with the planar laser induced fluorescence(PLIF) and high-speed photography techniques.The temperature contour on the slice plane of fin symmetry was measured and the heat flux contour was processed based on gradient computation.It is confirmed that:1) PLIF with high-speed photography is very powerful technique to investigate the multiphase flow of hypervapotron quantitatively;2) evaporation is the primary way in heat transfer mechanism of hypervapotron flow under the condition of high heat flux.The techniques and results obtained will provide useful reference in the R&D of hypervapotron technology in China.
