| 摘 要： | 对粮仓机械通风的均匀性用3种检测方法进行了试验和分析.试验表明:表面风速法不能反映出粮食杂质的具体分布情况和整个仓房的通风均匀性,静压法和温度法能反映出杂质具体分布情况,但温度法会受到客观环境的限制以及存在滞后性.

| Abstract: | The evenness of granary mechanical draught was tested and analyzed with three methods. The experiments showed that the method of surface wind speed could not reflect the concrete distribution conditions of grain impurity and the ventilating eveness of the whole storehouse. On the contrary, pressure and temperature methods can reflect the concrete distribution conditions of impurity, however, temperature method can be limited by objective surroundings and has delay-action. |

| Keywords: | still pressure temperature surface wind speed mechanical draught |
