提出了对空中点目标进行被动测距的方法。基于红外辐射在大气中的传输规律和红外成像系统的特性，建立了目标和背景的表观对比度模型。通过对两个波段上对比度模型的分析，推导出了测距公式和距离分辨率公式。理论分析表明，只要得到大气在两个波段上的消光系数，通过测量目标在两个波段、两个时刻上的目标表观对比度，即可计算得到目标距离和目标径向速度，而距离分辨率则取决于系统的对比度探测能力及相关参数。

The purpose of the research was to obtain bacterial polyhydroxyalkanoic acids producers with good characters. With bottom sludge from Donghu Lake, bum soil from hillside, fertile vegetable soil and oil-soaked soil as initial samples, the bacterial strains with ability of synthesizing PHAs were screened not through enriching, isolation and purification, staining with Sudan black B and qualitative and quantitative analyses by infrared spectroscopy and gas chromatography. The results of staining with Sudan black B showed that there were 3 strains with ability of synthesizing PHAs among the 12 isolated strains and their numbers were Zj-5, Zj-8 and Zj-9 resp. All the 3 strains took on adsorption peaks at the points near 1741 cm^(-1) and the infrared spectrums of the strains Zj-8 and Zj-9 were similar.
