查询词典 headwater erosion

High effective decontamination with minimum remainder, erosion, destruc- tiveness may be realized by taking advantage of the high diffusivity, low viscosity, rea- sonable solubility and special separation property in supercritical phase, during which the recycle and reuse of the materials is promoted and the cost for waste management is reduced to the least.

The decreased threshold shear velocity and unsaturated sand flows at the stoss slope of the dunes resulted the erosion at the toe of the dune. Under the medium and low drifting-sand winds the sands being transported have divergence with that on the surface, the mean grain size of transported sands is lower than that on the surface and the sand transporting is a stochastic process.

起动剪切速度减小与不饱和风沙流是沙物质在横向沙丘迎风坡坡脚不能产生沉积的主要原因；再者，平均风速并不能完全反映野外实际状态下气流的性质，在低－中强度的风沙活动过程中，被输送的沙物质的粒度组成与下垫面物质有明显的差异。

The field experiments on the near surface airflow, sand transport rate, grain size of the dune sands and the morphology of the dunes show that though shear velocity decreased at the toe of the transverse dune, the threshold shear velocity decreased simultaneously.
