Abstract:用分子束外延方法在ＧａＡｓ（１００）衬底上生长了Ｚｎ１－ｘＭｇｘＳｅ（０≤ｘ≤１）三元半导体合金薄膜．在室温下测量了这些样品的红外反射光谱．采用介电函数的经典色散理论，并且考虑衬底的影响后，计算了样品的红外反射光谱并与测量结果作了比较．我们发现对于ｘ＜０．２，０．２＜ｘ＜０．５和ｘ≥０．５三种不同情形，反射光谱表现出不同的结构．

Abstract:在Ⅲ－Ⅴ族半导体ＧａＡｓ外延层上共注入Ｅｒ和Ｏ离子（ＧａＡｓ：Ｅｒ，Ｏ）．经面对面优化退火后，光致发光（ｐｈｏｔｏｌｕｍｉｎｅｓｃｅｎｃｅ－ＰＬ）谱中观测到对应Ｅｒ３＋第一激发态到基态４Ｉ１３／２－４Ｉ１５／２跃迁，其相对强度较单注入Ｅｒ的ＧａＡｓ（ＧａＡｓ：Ｅｒ）增强１０倍，且谱线变窄．从二次离子质谱（ＳｅｃｏｎｄａｒｙＩｏｎＭａｓＳｐｅｃｔｒｏｍｅｔｒｙ－ＳＩＭＳ）和卢瑟福背散射实验给出退火前后Ｅｒ在ＧａＡｓ：Ｅｒ样品中的剖面分布．ＳＩＭＳ测量分别给出Ｏ注入前后Ｅｒ和Ｏ在ＧａＡｓ：Ｅｒ，Ｏ中的深度剖面分布，分析表明Ｅｒ和Ｏ共注入后形成光学激活有效的发光中心．

Abstract:Extinction of infrared radiation through continuous rain was measured with an infrared spectral radiometer at the wavelengths of atmospheric windows. Experimental results show that the extinction by rain is closely correlated with the precipitation rate. The quantitative relationship between extinction and precipitation rate was obtained from the experimental results. Extinciton by rain was also calculated using the Marshall Palmer particle size spectral distribution, and the calculated extinction coefficient coincides with the measurement results quite well when the forward scattering correction is considered.

Abstract:The noise produced by a randomly distributed low thermal conductivity (LTC) layer on the outer surface of a metal tube when using infrared imaging technique to detect the corrosion defects on the inner surface of the tube was studied. The different influences of LTC layer on different heat loading methods were also studied both theoretically and experimentally. A new approach to diminish the high power noise produced by LTC layer was proposed in the end.

Abstract:According to the uncertainty existing in the process of acquiring information of spatial ballistic target and its accompanying decoy, subjective Bayesian method was used to recognize these spatial targets. In order to satisfy the premise of necessary knowledge and experience for applying subjective Bayesian method, neural network was used to replace the experts of relevant domains. The method to combine neural network and subjective Bayesian was introduced, and a multi sensor data fusion model to recognize spatial complex ballistic taget and its accompanying decoy was given.The results of emulation show that the recognition rate is improved much.

Abstract:The annealing effects of InAs layers with different thicknesses in a GaAs matrix were investigated. The diffusion enhancement by strain, which is well estabished in strained quantum wells, occurs in InAs/GaAs quantum dots(QDs). A shift of the QD luminescence peak towards higher energies results from this enhanced diffusion. When a significant portion of the strain in the structures is relaxed by misfit dislocations, the diffusion becomes negligible, and annealing tends to generate additional dislocations. By these why the QD peak energy is weakly affected and the luminescence intensity decreases could be explained.
