摘要:
在对野外风沙流进行实测的基础上,运用拟合曲线、拟合方程等方法对0～8cm垂直高度层内风沙流结构进行了分析研究.结果表明:0～8cm高度内总输沙率及各高度层输沙率均与风速呈幂函数关系;各高度层输沙率百分比与风速呈指数函数关系;各高度层输沙率与高度呈幂函数或指数函数关系;上、中、下各层输沙率与总输沙率呈良好的幂函数关系.
Abstract:
On the basis of open country sandstorm,the usage drew up to match curve and drew up to match fitting equation etc.method perpendicular and high sandstorm inside the layer to flow structure to carry on an analytical research to 0-48 cm.The result express:the sand transporting rate in 0-48 cm height inside and each high layer all present the power function relation with wind velocity;the rate percentage of sand transporting in each high layer and wind velocity to present the exponential function relation;the rate of sand transporting in each high layer and height to present the power function or the exponential function relation;the sand transporting rate in upper,middle and lower layers all present the good power function relation with the rate of sand transporting in 0-48 cm height inside.
