It solves the imaging problem in great contrast. In chapter 2, the author deeply studies and analyzes the arithmetic of the method of Born approximation inversion and points out the limitations and disadvantage of the method. The good inverse results can be obtained in little disturbance by Born approximation.

In the first step,through using the formula of the conformal transformation,a continuous medium with regulation boundary in original area could be transformed to a homogeneous medium with anomalous boundary in complex area,so the new constant velocity field could be more adapt to the current Stolt migration's conditions.
首先,利用保角变换法可将不规则边界的单连通区域转变成规则边界的原理,将规则边界的连续介质场转变成不规则边界的均匀介质场,使该均匀介质场更适应现有Stolt等偏移方法对速度场的要求;其次,对改变了区域的模型地震记录进行常规的偏移成像处理;再利用推导出的反变换公式对成像结果进行反变换,得出模型的真实偏移成像结果。

Based on the prior information obtained by qualitative inversion, the two stages inversion method was put forward. That is, the first stage is that distinguishing the high-quality element and non- high-quality element, and determining the initial iteration value of element sound velocity reasonably. The second stage is that treating differentially the constraint weights of the high-quality element and non- high-quality element, and then quantitatively inversing the final sound velocity distribution. The results of two concrete specimens indicate that the two stages inversion method can inhibit artifacts effectively and has better defect identification effect than normal one stage inversion.
在获取定性反演先验信息的基础上,提出了两阶段反演的方法:第一阶段,区分优质像元和非优质像元,合理确定像元声速的迭代初值;第二阶段,区别对待优质像元和非优质像元的约束权重,定量反演最终的速度分布。2个混凝土试件的模型试验表明,两阶段反演能有效抑制伪像,具有比常规的一阶段反演更好的缺陷识别效果。

During the past long period, much progress has been realized on the study of the retrieval of LST based on remote sensing, and many algorithms for the LST retrieval have been developed. However, in these algorithms non-isothermal mixed-pixels are all treated as an isothermal and homogeneous surface, which caused directly the results that the LST obtained by these algorithms is only an average temperature of mixed-pixel.
在过去很长一段时间里,地表温度的遥感反演取得了长足的进展,发展了大量的反演算法,但是这些算法都把普遍存在的非同温混合像元视为同温同质体,直接导致反演所得的只是物理意义模糊不清的混合像元的平均温度。

Lemon tree 歌词:I'll sitting here in a boring room, It's just another rainy sunday afternoon, I'm wasting my time I got nothing to do, I'm hanging around I'm waiting for you. But nothing ever happens and I wander. I'm driving around in my car, I'd like to change my point of view, I feel so lonely I'm waiting for you, But nothing ever happens and I wander. I wander how I wander why yesterday you told me about blue blue sky; and all that I can see is just a yellow lemmon tree, I'm turning my head up and down I'm turning turning turning turning turning around and all that I can see is just another lemmon tree. see,dalada,diladada... I'm sitting here I miss the power, I'd like to go out taking a shower, but there's a heavy cloud inside my head, I fell so tired put myself into bed, but nothing ever happens and I wander. I solation is not good for me, I solation I want to sit on a lemmon tree . I'm stepping around in adesert of joy, baby anyhow I'll got another toy, and everything will happen and you'll wander. I wander how I wander why ?
中文翻译:一个人孤单单的下午当风吹得每棵树都想跳舞记得昨天你穿蓝色衣服你说对爱太专注容易孤独这句话什么意思我不清楚我爱上了云爱上你多么希望像你自由来去原来星期天容易思念反覆看部电影一遍一遍孤独的流著眼泪回忆太美爱多美丽充满香气只是在心里它总是酸溜溜地我不懂我自己越来越像 Lemon Tree 我一天一天更爱你我不管不管不管爱会苦苦地海蓝蓝的天气我的爱是 Lemon Tree 我爱上了云爱上你多么希望像你自由来去原来星期天容易想念反覆看部电影一遍一遍孤独的流著眼泪回忆太美 Isolation 想住进你心里 Isolation 期待下雨的一棵 Lemon Tree 你总是望著蓝蓝海面说著流浪过的梦容易实现这句话什么意思我不清楚爱多美丽充满香气只是在心里它总是酸溜溜地我不懂我自己越来越像 Lemon Tree 我一天一天更爱你我不管不管不管爱会苦苦地海蓝蓝的天气我的爱是 Lemon Tree 哦。。。。

The following results are made from this research: Assessing data quality and band combination of different bands in line with geo-target features in desertification areas, and determining basic bands for desertification monitoring. And understanding and studying the spectral features and variation rules of geo-targets in the experimental area, raising that it is the basis of geo-targets information collection with imaging spectrometer data to understand spectral features and variation rules of geo-targets, realizing that in a great extent spectral-integrated-form-based classification method can remove the phenomenon of "different spectrum with same objects" resulted from reflection ratio curve translation because of the angle change among sensor, targets and observation direction, and the average and variance images can be introduced to solve the problem of two kinds of geo-target with similar spectral forms and much different values of whole reflectionratio. It is suggested that "red edge" range bands of vegetation, which has close relationship with vegetation cover and biomass, is the main characteristic bands and important basis for careful vegetation classification and quantitative retrieval, and pixel-based derivative spectral analysis is very useful for removing the effects of soil background values and quantitatively retrieving vegetation biomass and cover. The remote sense quantitative retrieval model is developed for main appraisable factors of desertification monitoring assessment with imaging spectrometer data and then the applicability of model is analyzed.
