相对体积 meaning in English
relative volume
Examples
- The relationship between volume of each part of model and its surface area can be described by gaussian model
流域模型各部分相对体积与其表面积的变化关系可由gaussian模型来描述。 - Because change of volume reflected eroding process of watershed and surface change reflected change of topography surface , this model described relationship between watershed topograph and erosion
由于相对体积变化反映了流域遭受侵蚀的过程，而表面积变化体现的是地形表面的变化，因而此关系模型同时表述了流域地形与侵蚀之间的关系。 - Iii ) the result from simulating rainfall on watershed model indicats that changes of projective area , surface area and volume represented development of watershed physiognomy . volume of model body decreased and projective area and surface area increased with developing process of watershed model . when development of gully trending to stablization , projective area become stable and surface area changed fluctuantly
( 3 )流域模型的模拟降雨实验观测结果分析表明：流域模型地貌的发育演化主要体现在其投影面积、表面积和相对体积的变化上；流域模型投影面积和表面积在整个试验过程中一致增大，当沟道发育逐渐趋于稳定时，投影面积变化也趋于稳定，表面积则呈现出波动性变化。 - Topography fractal dimension related with process of development of watershed physiognomy and represented degree of watershed development , v ) sediment yield intensity of watershed model reflected erosion characteristic of watershed model in different development phase . simulating experiment indicated that sediment yield intensity took on the trend that they changed from small to big then decreased gradually . the relationship of average sediment transport rate and sediment yield rate per mm rainfall with topography fractal demension is expressed by gaussian model and this model is similar with relationship between volume and surface area
( 5 )流域模型产沙强度的变化反映了流域模型在不同发育阶段的侵蚀特征，模拟试验研究结果表明：在整个流域模型地貌地貌的发育过程中，其产沙强度呈现由小到大，然后又逐渐减小的总体趋势，流域模型单位降雨产沙率及平均输沙率与地形分维数表现为gaussian模型关系，其关系形式与结论3中相对体积和表面积之间关系相似，进一步说明了以地形分维数表达地形变化的合理性。
