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.

A technique of massive scale data management and attemperation based on viewpoint. This algorithm effectively changes massive scale terrain into large scale ones to handle. Utilising the continuity of the viewpoint movement and the relativity of fore-and-aft frames, it manages and attempers the terrain data leading to data decrease in a large range. This algorithm solves the problem of the rendering rate, and realizes a rapid real-time ramble in massive scale terrain scenes.

After that, a numerical model about Zhejiang shore tide is established by mike21 program. After validating the good agreement between simulated results and observed ones, the planar hydrodynamic flow of this ocean area is analysed in detail. Then co-tidal and co-range chart of each main tide is drew based on the computational result. It can be found that each co-tidal and co-range chart that is based on the simulated result is suitable to the co-tidal and co-range chart that is deduced from autoptical data, besides, the modle co-tidal and co-range chart can perfect the co-tidal and co-range chart from autoptical data where autoptical data is too hard to get .

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
