The fundament of flat terrain phase effect and its removal are stated. The interferogram consists, for each pixel, of the complex conjugate product of two SAS images directly, which cant reflect the actual terrain change. The general phase trend in range can be considered as the phase generated by an ideally flat terrain and is often subtracted from the interferogram before further processing.

Namely, the first, the beginning, end and length of growing season of every type of vegetation is estimated with threshold method and moving average method, and the beginning end and length of growing season of vegetation from 1982 to 1999 is fitted linearly, finally, linear trend of the beginning end and length of growing season of vegetation is analyzed. The second, phenological phase in different years and zones is estimated based on greatest changes of slope method and EOF analysis method, and the result monitored by the two methods is compared, as a result, trend of growing season change from 1982 to 1999 in different latitude zones is better acquired. The third, phenological phase of vegetation in different spatial location from 1982 to 1999 is fitted based on curve. Then, spatial difference rules of growing season of every year and average of multi-year is discussed in article. In the end, lag correlation and linear regress are used to study relation between phenological phase of different types of vegetation, different latitude zones, different spatial places and climate changes.

The results showed that the TiN andN films are polycrystalline phase. The properties and structure of TiN films are mainly determined by the N2 mass flow rate, and as the N2 mass flow rate increases, the structure of the TiN films transforms to f.c.c. type leading to better the properties of films. The presence of negative bias voltage can optimize the grain of TiN films, lower the defect proportion and denser the films, which improves the hardness of films. The TiN films conform to the free carrier absorption mechanism and there are many of free electrons with lower N content in TiN films. With the increase of N content, the quantity of free electrons and reflectivity of films decrease, and the plasma frequence shifts to the lower energy, which leads to the regular change of colors of films from silver, yellowy, golden to yellow-red, meanwhile the lightness of films decreases. The goldenN film consists of TiN and ZrN phase, but belongs to a sigle f.c.c. structure with (111) preferred orientation. The Zr-doping dosen't change the position of the valance band, conduction band and forbidden band ofN film, but leads to the presence of new energy levels, which is the reason thatN film remains golden. The transparent hard films with good corrosion resistance and high hardness have been prepared and the further reseachs showed that the grain size of those films is by far smaller than the wave length and the width of forbidden band of those films is very broad, is the reasons that those films are transparent.
研究表明:氮化钛和N 薄膜为多晶态,氮流量决定了氮化钛薄膜的结构和性能,增加氮流量能使氮化钛薄膜的结构向面心立方结构转变,从而得到性能良好的氮化钛薄膜;施加负偏压能优化氮化钛晶粒和减少薄膜中的缺陷,使膜层变得更致密,从而提高薄膜硬度;氮化钛主要遵循自由载流子光吸收,氮含量较少时薄膜中的自由电子数目较多,随着氮含量的增加,薄膜中的自由电子数目不断减少,反射率逐渐降低,等离子体频率向低能端移动,从而使薄膜颜色出现规律变化,由金属色银白色到淡黄、金黄再到红黄,并且薄膜亮度呈下降趋势;金黄色的N 薄膜中存在TiN 和ZrN 的分离相,但其为单一的面心立方结构并具有(111)面择优取向;相对于TiN 薄膜,Zr 掺杂后,并没有使薄膜的导带、价带和禁带发生变化,只是在TiN 禁带内增加了新能级,这也正是掺杂Zr 后,薄膜仍
