Example Sentences:

	1.	Based on wind speed observation record with drawback , it is proved that the exponent expressing terrain roughness can be calculated according the monthly maximum wind speed records at various height levels . wind characteristics of bridge site are determined by statistical method 针对桥址区风速观测记录的特点，证明了利用不同高度处月最大风速记录推算地表粗糙度影响系数的可行性，并对通过最小二乘拟合得到的地表粗糙度影响系数进行统计分析，最终确定桥址区风特性。
	2.	The principium of the simplification criterion is that the light eradiated from surface will attenuate during it ' s transmission , so the light energy eradiate from the surfaces far from the viewer will become too faintness to attract the viewer ' s attention , thus the surfaces far from the viewer can be emerged into larger surface , then by combining with the residual light energy and terrain roughness , the new simplification criterion is formed 本文根据光能衰减原理，从人的视觉效果出发，认为由于地形面片辐射的光能将随着距离增加而不断衰减，所以距离视点较远处的面片辐射到视点的光能必然很微弱，这样就可以将远处的面片合并成较大的面片，从而达到简化地形的目的。
	3.	To the influence of the plateau terrain , the impact of the elevation and the roughness of terrain to every energy component out and incoming are study , and basing the soil spectrum model proposed above , a new radiative transfer model of terrain area was put forwarded in which the soil water content , lai , terrain roughness and elevation were considered synchronously , and incoming scatter light was integral with the solid angle of semi - globe space defined by the slope of the pixel , so scattering lights of terrain and the sky are properly considered , but the operation is still within the acceptable range 地形与反射率的关系是本文研究的一个重点。本文对崎岖山地象元的各入射光和反(散)射光分量进行了深入分析，在所提出的湿润土壤光谱模型和植被冠层模型的基础之上进一步提出了新的适合青藏高原的山地辐射传输模型。该模型同时考虑了土壤含水量、植被覆盖( lai ) 、地形起伏和海拔高度的影响，并以象元坡面定义的半球空间立体角对环境入射光进行积分，使周围地形和天空散射光均得到适当考虑，计算量又在可接受范围内。
