Simulating the effect of wind erosion on aeolian desertification process of Horqin sandy land and it
[期刊论文] 作者：Cai Xia Zhang,Jin Chang Li,
来源：寒旱区科学（英文版） 年份：2022
Samples from the Horqin sandy land were exposed to a series of wind velocities, and sink particles were collected at the end of the diffusion section of a wind tunnel. Grain sizes of collected samples show great variation because of the gra......
