This paper introduces the concept of apparent motion, and by examining the characteristics of apparent motion and of velocity vectors, puts forward a new speed reduction method in tunnels. Finally, we verify this effect through a simulation experiment. The experiment first used 3DMAX to make...

There has been very limited research on water use efficiency for soil conservation (WUE-SC) in typical water scarce regions such as the lower Heihe River Basin, where there is serious wind erosion and the soil conservation service plays a key role in guaranteeing the ecological safety of...
