空间变率 meaning in English
space rate of change
Examples
- Numerical experiment shows that this heterogeneous disturbance arising from soil water content ' s spatial variability cannot be neglected when regional mean evaporation fluxis estimated
数值试验表明，这种因空间变率而引发的非均匀扰动项在估计区域平均通量时具有不可忽视的影响。 - To demonstrate the heterogeneity of hydrological flux and the significant influence on regional evaporation , firstly , it is proved theoretically that because of soil water content ' s horizontal spatial variability ( heterogeneous distribution ) an additional heterogeneous disturbance which is equivalent to mesoscale flux is induced
首先从理论上推证出：由于土壤水分所存在的水平空间变率(非均匀分布，对网格区平均通量而言，可引发附加的量级与中尺度通量相当的非均匀扰动项。 - In this paper , starting with the physical mechanics of land surface hydrologic process and the introduction of the theory in probability statistic distribution , an analytical expression of heterogeneous evapotranspiration efficiency is given which takes heterogeneous soil water content ' s subgrid scale spatial variability into account , through which the parameterization scheme of subgrid scale soil surface ' s evapotranspiration efficiency ( which is generally called mosaic method ) is modified to a statistic - dynamic scheme in which a whole heterogeneity of the grid region is considered
本文从陆面水文过程的物理机制出发，引进概率统计分布理论，推导出一种由非均匀土壤含水量次网格尺度空间变率所形成的非均匀蒸发散率解析表达式，从而将通常的次网格尺度地表蒸散率的参数化方案( mosaic方法) ，改进为考虑网格区整体非均匀性的统计-动力参数化方案。
