Influence of aggregate particle size on the expansion behavior of mortar bars under autoclave condition;

Preparation of mixed particle sizes of Ni(OH)_2 electrode and its charge-discharge performance;

On-line Particle Size Measurement Using Light Extinction;

Comparison and research of grain size measurement of ultrafine powder;

When the grain size decreases, the moisture sensitivity increases, and the time of effect increases too.

Effect of carbon particle sizes on microstructures of TiC_p reinforced magnesium matrix composites by in situ reactive infiltration process;

The results show n that the higher the shear rate,the finer the dispersed phase size.

By analyzing the influence of the out-size granule in geo-compactness on the maximal dry density,some measures for disposal of out-size granule in practice are presented,which proved the scientisticness and rationality of the corrected formula for this problem in"Test Methods of Soils for Highway Engineering".
