Model RWM within the ARSIS concept (Ranchin and Wald 1999) and the P+XS algorithm (Anonymous 1986). A comparison of the synthesised images demonstrates the possible misinterpretation that can result from an non-appropriated method. A quantitative assessment is then performed of the synthesised images. These two comparisons enhance the quality of the method derived from the ARSIS concept.

研究基于TM遥感影像,运用多种方法针对典型内陆淡水湿地的水体信息进行了提取实验,通过对实验结果的分析得出:在面积的准确性、提取的准确度以及视觉效果3种指标下,光谱分类法较其它方法效果要好,其次为单波段阈值分析法与植被指数法,较差的是多波段谱间关系法与水体指数法;影响提取效果的主要原因是湿地水体提取不够完全,这是由影像的分辨率及湿地特殊的水文条件所造成的,采用像元分解及多源遥感数据融合技术将成为提高水体提取精度的重要手段。

A photonic crystal-air interface or line defect is utilized as a holophote or a partial reflective mirror to design a paralleled plane cavity, a single ring cavity structure and a multi-ring cavity structure. The method has simple design idea, good integration and wide application; by adopting the method, the self aligning photonic crystal lasers with different wave bands can be designed according to the luminescent characteristics of different materials; particularly, the utilization of semiconductor materials to design a light source of optical communication wave bands has more important practical value.

Millisecond time scales in the X-ray light curve of Scorpius X-1. The estimated sizes of these occulting TNOs are about or less than 100 m. This is the first time that TNOs of such a small size are detected. Our discovery of the X-ray occultation demonstrates a new method to study smaller TNOs.

The study about the flux and index of gamma-ray loud blazars show:(1)there is significant correlation between the luminosities in gamma-ray and VLBI radio energy band;(2)there are strong anticorrelarions among the observed indices of soft X-ray, hard X-ray and gamma-ray. For the FSRQs, the whole X-ray emission was contributed by synchrotron self-Compton emission, for the HBLs, the X-ray emission was dominated by synchrotron emission while the soft X-ray emission is dominated by synchrotron emission and the SSC emission dominate the hard X-ray energy band for LBLs;(3) there are strong radio-radio and radio-optical flux correlations for the quasar 3C 273. The higher frequency emission leads those in lower frequency. The multi-band complex indices strongly correlated with the high frequency flux which implies that the object is becoming bright when the energy spectrum is harden.
通过对γ噪Blazar天体的谱指数、流量的相关研究,发现(1)51个样本blazar的γ射线光度与VLBI光度之间存在显著相关;(2)软X、硬X以及γ波段的观测谱指数之间存在较强的反相关,对FSRQs,无论是硬X射线还是软X射线的辐射都是逆康普顿辐射的贡献,而对于HBLs来说,则是同步辐射的贡献,对LBLs,在软X射线波段以同步辐射贡献为主,在硬X射线能区以逆康普顿贡献为主;(3)3C 273的射电各个波段以及光学之间存在强相关,高频辐射一直领先低频辐射,3C 273的多波段复合谱指数和高频流量之间存在强的反相关,意味着当能谱变硬时对象变亮。
