    摘要:

    運(yùn)用改進(jìn)后的大氣采樣器對(duì)棚室內(nèi)距地面1.5m高水平面上不同位置采樣,，將采樣后得到的藥?kù)F質(zhì)量濃度采用三次樣條函數(shù)插值法建立藥?kù)F質(zhì)量濃度分布曲面。對(duì)分布曲面分析表明：沿棚室長(zhǎng)度方向上,，噴頭前方10～12m區(qū)間中藥?kù)F質(zhì)量濃度最大,，煙霧機(jī)作業(yè)的有效區(qū)域?yàn)閲婎^后方10m、前方32m,，共42m,；寬度方向上,，藥?kù)F質(zhì)量濃度中間低,，兩側(cè)高。

    Abstract:

    In order to solve the problem of mass concentration of pesticide fog after application in airtight space, an improved container collecting the air samples was used at different locations in the level of 1.5m from ground, and curved surface of mass concentration of pesticide fog was established based on cubic spline interpolation. It was showed that the pesticide mass concentration attains maximum at 10～12m in the front of the nozzle, and the effective regional of cold aerosol sprayer is 42m, from 10m in the back of the nozzle to 32m in the front of the nozzle, in length; and the pesticide mass concentration was lower in the middle of airtight space than the sides of it, in width. 
