The reflective law of color fluorescent ink half tone is generalized by utilizing the idea that the reflected light by fluorescent print is divided into two parts: primary streams which consist of originally incident light and fluorescent streams which are created by absorption of the primary stream. And an exponential matrix modelizing the layer of fluorescent ink is utilized to compute the energy of fluorescence.

目前我国东部的石油勘探工作已进入精细勘探阶段,如何确定陆相地层中薄储层的空间展布规律及其性质已成为一个亟待解决的问题,由于我国东部的绝大多数中、新生代陆相含油盆地大都以薄层砂、泥岩沉积为主,夹有少量薄层碳酸盐岩、页岩及膏盐层,地层岩性和厚度横向变化均较大,而且这些地层的厚度远远低于常规地震勘探的垂向分辨率,因此,从理论上研究沙泥岩薄互层地震反射特征、薄互层组内的单层厚度、子结构厚度、互层组内层数、入射子波类型、主频、采样率等各种因素对反射波特征的影响,将对我们定性或定量求取薄互层组中各单层厚度或薄层组的厚度、预测薄储层的空间展布规律有一定的理论和现实意义。

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.
