In order to making an initial statistical research for the AGNs evolution, we investigated the distribution of the redshift and the spectral index and the flux densities in different wavebands.

从本文统计的谱指数和红移的关系图可以看出gamma波段的谱指数比x波段高，在天体的演化过程中是由高能量天体演化成低能量天体，从而得出一个演化序列：BL Lac天体过渡到低偏振类星体。

The original HyMap data were derived from Barrax test site in Spanish at 9:00 o'clock,June 4,1999,the air altitude was 3 500 m,and the spatial resolving power was about 5 m.the spectral range of HyMap airborne imaging spectrometer was 400~2 480 nm,there were 128 wavebands except two with high vapor absorption near 1.4 μm and 1.9 μm.

成像光谱技术，又称高光谱遥感技术，起源于20世纪70年代初的多光谱遥感技术，是近20年中人类在对地观测方面所取得的重大技术突破，是21世纪遥感技术研究的前沿领域之一，是遥感技术发展的重要趋势之一，其数据的光谱分辨率达到10 nm[1]。

A multi-band optical system was designed for the push-broom space camera covering visible,medium infrared and far infrared wavebands.

空间推扫相机的光学系统要求具有大视场、大口径、低F数等特点，据此设计了一种3波段光学系统。

By establishing a model based on the law of infrared radiation transmission in atmosphere and the characteristics of infrared imaging system for the apparent contrast between the target and the background, and analyzing the model over two wavebands to formulate the distance measuring formula and the distance resolving power formula, a passive distance measurement method is proposed for aerial point target distance measurement.

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 system can be widely used in belt weighing and batching process control,etc.
