For making clear that this phenomenon bring physical mechanism, this paper study windbreak effects and controlling the sand blown flow of low cover Artemisia.

Correlation analysis of canopy reflectance and coverage of rape in semi-wet rainfed agriculture area;

Research of coverage and connectivity problems in wireless sensor networks;

Crop straw and stubble coverage can reduce the shearing force upon soil surface by wind and therefore effectively restrain soil wind erosion.

Significant difference was found in natural enemies community and populations among vegetations with different degree of coverage.

Attribute significance is considered from the increment of dependence of attribute,the increment of mutual information and the measure of combine degree of nicety with degree of coverage,and which is regarded as heuristic information in the heuristic algorithms.

Evapotranspiration and water use efficiency of potted pakchoi under different surface coverage degrees

Results of simulating Experiment on Normal Integral Model of different forest and grass coverage degrees,show that forest and grass measures of small watershed are effective in reducing runoff and sediments.

In this paper, we propose the GTSA(Grid Template Scan Algorithm and computer the coverage degree in the wireless sensor network aiming to simple wireless network.

The relationship between the cover degree of the surface and the concentration of solution is given .
