The influence of high temperature and high pressure on foaming agent's properties in opened and closed system, and influence of the change of foaming agent's properties on foaming capacity and foam stabilizing capacity are also studied. The multiple regression theory is used to establish the quantitative characteristic functions of foaming agent versus temperature and pressure. Based on the Gibbs Principle, the quantitative characterization is carried out on relation of foam system's free energy versus its surface tension, surface area and concentration, and the analysis of energy concluded that the disintegration of the foam is inconvertible. At the same time, the influence of change of foam's shape and structure on distribution of reservoir temperature and pressure is qualitatively described, and the coupling mechanism between temperature field, pressure field and chemical field is systematically expounded.

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.
