The porosity and pore size distribution of HVFA pastes and concretes were determined by autoscan porosimeter. The results show that excessive fly ash content and comparatively high water-cementitious materials ratio will cause a big increase in porosity and harmful pore in HVFA pastes.

首次把X射线小角散射技术用于测定高掺量粉煤灰水泥浆体气孔—固体界面的分形维数，并就粉煤灰掺量、水胶比对气孔—固体界面分形维数的影响进行了分析，发现过高的粉煤灰掺量和较大的水胶比均会使分形维数大幅度增加。

The fresh weight and basal diameter of the cut curcuma flowers decreased with time after harvested without inserted them into water immediately. Thus, the vase life decreased. The even of the off-water time is only 30 minutes. One gram of fresh flower can absorb 30-40mg of fresh water, and the vase life increased 2-4 days if the stem base were recut, The curcuma flower per se after carting didn't posses peak of respiration and release of ethylene as well.

姜荷花切花采收后随著离水时问增长，鲜重与花茎基部直径渐减，瓶插寿命亦随之缩短，离水仅0.5小时切花即明显受要影响，花茎基部重新切除可增加10-20mg/gF.W的吸水量，而延长瓶插寿命，但同样随著离水时间延长而降低瓶插寿命。
