| 摘 要： | 集沙仪是指用于风蚀采样中的仪器。室内试验中,在风洞内对点阵集沙仪和BSNE集沙仪进行等动力性试验研究的结果表明,降低进沙口的高度有利于提高集沙仪的等动力性,但由于影响等动力性的因素众多,探寻出主要的影响因素尚需做深入的研究。

| Abstract: | Sand collector is an apparatus for wind erosion sampling. The results of indoor equidynamic test and study on lattice and BSNE sand collectors in tunnels show that although it is favorable for increasing the equidynamic of sand collector by reducing the height of inlet, variable cross-section sand collector is advantages for diffusing the air-flow in the sand collector. Due to numerous factors that effected equidynamic, it still needs further study to find out the main effect factors. |
