  1. The position and size of the monochromator, focusing curvature radii and tilting angles of the germanium focusing monochromator under different different take - off angle, size and divergency of the second collimator and intensity loss due to the use of it were determined. the neutron flux at different wavelength, under different reflection and take - off angle of the monochromator and divergency of the first collimator, were given. the simulation on the aperture used for limiting beam size in front of the sample showed that, smaller the size of the aperture and further the distance from the aperture to the sample, greater the loss of the intensity and more serious the spread of the beam along vertical direction at the sample position which makes the practical sampling volume greater than expected

  5. Abstract : the reflective characteristics of sea and sky background radiation, which have important effect on the infrared signature from flight vehicle above sea, are studied in the paper. the statistical distribution of wave facet directions is discussed, the effects of randomly riging and falling sea wave on the sea surface radiation and on the sun light reflection are also discussed. calculation methods of irradiance from sea surface radiation and reflected sun light on observation point are derived in the paper. finally a computation example is given, which shows the sea and sky background radiation has important effect on infrared characteristic especially in the front area of a flight vehicle

    文摘:研究了對近海飛行體的紅外特性有重要影響的海空背景輻射的反射特性.討論了波浪面起伏隨機規律，隨機起伏對海面自身輻射及對陽光反射的影響，推演了此種隨機起伏波浪面的自身輻射及反射的陽光在觀測點形成的輻照度的計算方法.給出的算例結果表明，海空背景對飛行體的紅外特性尤其對其前半球的紅外特性有重要的意義
