摘　　要：音平控渣技术中,取声是关键。弯管取声可避免直管取声的一些不足之处。因而用实验方法研究了弯管取声中各段管长与滤波频率的匹配关系,通过分析比较对应的音平曲线得到较佳的匹配关系,对确定弯管取声中各段管长具有一定的指导意义。The sound collecting was a key point in controlling slag by sound level, the sonic detection by siphon could avoid many demerits of using straight tube. The matching between the tubes' length and the filtered sound frequency in siphon was studied by test. A better matching relation was obtained by analyzing and comparing the respective sound level curves.
