The results indicate the average sampling efficiency to 0.6~0.15mm is high intermix dust and 0.015 mm followings in 6、9、12、15、18m/s wind speed. It is applicable to the acquisition of soil particles with the form of jump movement.
对不同结构参数的集沙仪进行了风洞性能正交试验(L_4(2~3)),试验结果表明:在6、9、12、15、18m/s五个风速下,集沙仪对0.15～0.6mm粒径土样的平均集沙效率高于混合土样和0.15mm以下粒径土样的平均集沙效率,说明布袋式集沙仪更适合采集以跃移形式运动的土壤颗粒。
