Contour plots of two-factor interaction were studied and some conclusions were obtained as follows: beef extract 5.7～8.0 g/L,peptone 5.2～8.0 g/L,temperature 33～35 ℃,pH 5.4～6.8 were best for more biomass growth.
(5) According to the theories and methods in the paper, by Visual C++ 6.0, we carried out modeling DEM, interpolation models constructing, reconstruction of the contour line and estimation to the accuracy of DEM and so on.
The paper introduces the development and applications of digital mapping,analyses the treatment of contour lines crossing steep ridge geology characteristic line and effects of geography line to automatic generation of contour lines and prospets the future of digital mapping technology.

It is found that the optimal resolution of the DEM is one half of the vertical-interval of contour lines,generally it should be 2.5m or 5m,the second roughness penalty is 0.8,and the number of iterations is 20-30 times.
The physical properties of EPDM vulcanizate could be predicted by isohypse,and the required physical properties of EPDM vulcanizate could be obtained by adjusting the loading levels of light calcium carbonate and naphthenic oil in the formula.
Reference grating formed by electronic oscillating signal and photoelectric conjunction Moire contouring of isohypse fringe based on electronic signal beat freguency principle are reported in the paper.
The method is based on the zonal linearization of the equation for mass conservation in the total flow between chosen surfaces or contour lines (lines of equal saturation or concentration).
A pattern of lines of equal displacement is obtained for a diffusely scattering surface of the plate with an eightfold enhancement of the sensitivity, with the distance between neighboring contour lines reduced to 15 μm.
Contour lines of the images of neutron point sources as functions of their number and position in the thermonuclear target are calculated.
One of the objects, with a resistivity of 25-40 Ω m, located at depths of 0-10 km, is most intense at a depth of 5 km, where the object is quasi-isometric in shape and has a radius of 10 km along the 40-60 Ω m contour lines.
