The procedure includes mathematic model building, geomorphoiogic structure line digitizing, original data pre-processing, automatic generalization of geomorphological valley lines,automatic contour selection, connection, and output.
In addition,combining map algebra research,the paper explains that there is a determinate spatial geometry relation between contour family and terrain structure line family,and the later is the broad sense Voronoi borderlines of the former. Therefore,F-S data is unnecessary when using contour data to produce DEM.
Zhangqiang area is located in jihei Geosyncline at north edge of Sino Korean Platform. lt's Premesozoic bedrock and structural feature are different from Sino Korean. The results obtained by means of 200km refraction profile are as follows: 1.The bedrock structure line is in the direction of SN or NNW.
The advantage Azimuth of the NW structure line has been authorized to, and has been widely used in various professional fields, but EW structures often been ignored, and this structure is a another major factor of affected the condition of the coal saved.
The ductile shear zone demarcates between the North China Platform in West Liaoning and Xing' an fold system in Inner Mongolia, which from E to W the direction of structure line gradually transited from EW to NEE, then NE.
The ability of power network maintaining its power supply reliability and quality is restricted by power network structure, line and load characteristics, generator drive device characteristics and relay protection mechanism.
Interface design focuses on data transmission, the line bit rate, frame structure, line coding, synchronization and timing, bit error correction/diction, link delay accuracy and cable delay calibration was all finished in FPGA chip.
This text attempts to probe into the production and development of culture and arts of the primitive dress by basic structure ,line kind and exposition of the function of the Traditional Clothing of She Nationality, understands deeply the marrow of Traditional Clothing of She Nationality.
In the low lying regions, connecting the prominence body and the chromosphere, we do not detect any fine structure line shift (v ? 1/2 km s-1).
The [CII (158 μm)] fine structure line, which is the principal cooling line of the atomic gas, in two nearby galaxies observed with LWS on board ISO is compared to dust and HI gas emission and heating intensity.
Ifthis is the case, luminous far-infrared fine-structure line emissionshould be detectable from both sources.
The measured fine-structure line fluxes can be fit successfully by a simple photoionization model invoking an EUV bump in the ionizing continuum, similar to the case of the Circinus galaxy.
Resonant photoexcitation of one atomic species by another often involves a ground configuration level from which an important fine structure line, used for density or temperature determination, may be emitted.
1. An X-band E. S. R. spectrometer has been constructed. Its sensitivity is such that 3×10~(-8) mole of DPPH can be detected by oscilloscope with S/N=15/1. The five byperfine structure lines of 5×10~(-4) M/1 DPPH benzene solution have been resolved.
The strong hyperfine structure lines of iodine-127 at 640 nm is observed by saturated absorption technique. The 127I2 cell is placed in a 3He-22Ne laser cavity, while the laser is modified to operate at 640 nm. The observed saturated absorption peaks have a contrast of 10% at pressure of 27 Pa. The saturated absorption at 612 nm is weak.
While a ~(129)I_2 (13%~(127)I_2) cell was placed into a He-~(22)Ne semi-inner laser cavity, a set of hyperfine structure lines of ~(127)I~(129)I molecule at 612nm was observed by using saturated absorption technique, and a comparison between the hyperfine structure lines of this molecule and of other Iodine molecules was also done.
