关于卡明斯基仪测定毛细上升高度方法的讨论

Discuss of the method for Kaminski measured capillary rise height

针对卡明斯基仪测定毛细高度方法在应用中的一些问题，利用卡明斯基毛细仪原理。进行了测定毛细上升高度的试验，确定渗透速度与毛细高度的关系，以及对比不同粒径毛细高度达到稳定时渗透速度，结果表明，随着渗透速度的减小，毛细高度减小，减小到一定数值时，毛细高度趋于稳定；不同粒径毛细高度达到稳定时的渗透速度也不同。

Aim at the problem of the application of Kaminski measure capillary height method,the pounds the test of capillary rise height based on the principle of Kaminski capillary instrument,and article ex- determines the relationships between the height of the capillary and penetration rate, and penetration rate at steady state of different size capillary high.The results show that,with the penetration rates reduced,the capillary height de- creases;decreases to a certain value,the capillary height trends to stable ;the penetra.tion speed different when different particle height of capillary trends to stable.
