Taking into account the squat silos with high grain line and large-volume storage characteristics, to ensure that the stored grain secu rity, we compared phosphine RECIRCULATION FUMIGATION OF PHOSPHINE with the conventional circulation fumigation method and compared with test data which measured by the analysis and research. Squat Silos taken positions on the circulation phosphine fumigation insecticidal methods, not only to achieve the purpose of the pesticide control, and effectively reduce the cost of fumigation, a decrease of gas in the fight against the occu pational hazards, and have achieved good results.  相似文献

The movement of lubricated fibres in a fibre assembly is investigated theoretically and aviscous sliding model of friction is proposed.Previous work and experimental results are discussedin relation to the model.Results of drawing experiments carried out on wool slivers are also pres-ented and discussed.  相似文献

Following a sticky particle model and its computer simulation scheme proposed in the previous papers, the motions of particles in both 2-and 3-dimensional shear flow fields are simulated. At a steady state of clustering process, the radial distribution functions are calculated to precisely describe the microstructure of aggregates in dispersions, and the configuration of particles is displayed,which gives a direct view of microstructure. It is found that (1) the kind of the microstructure transforms from compact clusters to a loose network as the concentration of particles increases; (2) the microstructure is independent of shear rate which only dominates the size of clusters formed at steady state.  相似文献
