通过各项指标区域横向对比发现，砂质古土壤层具有从西北向东南渐变厚变深的规律和粒度值从西北向东南由粗变细的规律。
The results showed that the water absorption ability of food super - fine powders could be determined stably and effectively by the self - made equipment , the water absorption abilities were different when the powders were made from different kinks of grains : the powders began to absorb water earlier and the speed of water absorption became rapider while the particle size of the powders was smaller , and the speed suddenly tended to increase and reached the limit value when the particle size of the powders was up to a certain value
实验结果显示：根据毛细原理自制的毛细吸水测定仪能稳定、有效地测定食品超细粉的吸水性；不同来源的超细粉吸水性不同；同一种食品超细粉粒度越小，吸水开始早、吸水速度越快；超细粉粒度达到某一粒度值时，吸水速率突然增大并达到极限。
