查询词典 spectral geometry

Hyperspectral remote sensing data has the characteristic of combining both image data and spectral data into one data set, each pixel of a hyperspectral image an entire spectrum (consisting of numerous contiguous, narrow spectral bands) is present. Compared with conventional multi-spectral remote sensing data, hyperspectral remote sensing data can be more useful for the identification and classification of surface Materials. In this paper, the author classified the coastal area using hyperspectral remote sensing data, and further more, succeeded in extraction of sand beach surface information related to bearing capacity characteristic.

It is found that there are no obvious corresponding signals related to the Slichter modes claimed by Smylie (1992), Smylie et al.(1993) and Courtier et al.(2000) in the product spectral density estimates. Instead, it is found that there exist 8 common significant spectral peaks in the subtidal band in the product spectral density estimates of the SCG gravity data, which may be related to some unknown global geodynamical or geophysical effects. It is very encouraging that the central periods of three peaks of them are estimated accurately as 4.93438 ±0.00186h, 4.42734 ±0.001159h and 4.09269 ±0.00082h, respectively, and in significant accordance with the eigenperiod of the Slichter modes of the solid inner core expected theoretically by Smith (1976) with only differences of 0.4%,-1.4% and 1.0%, respectively.

In sparkle discharge ,following conclusions could be reached:(1) overall spectral intensity in nitrogen is lower than in oxygen . When water is added, integrality light intensity is lower compared with the pure gas condition.(2) No matter it is nitrogen or oxygen, when water is added, syllabify three spectral lines of atomic H: Hα(656.3nm), Hβ(486.1nm), Hγ(434.0nm) could be seen. What is more, when water is added into oxygen, the spectral line of H atom becomes stronger.(3) When discharge in pure nitrogen, the light intensity falls with the increasing gas flow rate. While if water is added, the light intensity will rises with the increasing gas flow rate.(4) When discharging in pure oxygen, the light intensity rises with increasing gas flow rate. While if water is added, with increasing gas flow rate the light intensity initially will change as this:first rise, then saturate at about 140l/h, finally falls.
