筛上物

并用相对运动理论分析了筛上物的运动规律、运动条件，及其运动参数K（加速度比）在不同条件下的取值范围，并在振动筛上实测后加以验证。

The motion regularities and conditions of the material on the shaker were analysed according to the relative motion theory . The range of the K value ( the ratio of acceleration ) was determined under different conditions The result was verified on the shaker test-bed .

城市生活垃圾筛上物的热解研究及实验

Pyrolysis on Screen Residue of Municipal Household Waste

结果表明：垃圾筛分后筛上物的含水率明显降低，热值大大提高。

The result showed that screen residue had lower water content and higher heat value .

腐熟垃圾堆肥筛分后的筛上物有机物含量高于筛下物。

The organic matter content of oversized compost in screen was higher than that of undersized compost in the maturity compost .
