孔隙溶液系指充满于岩土孔隙空间的以及被固体颗粒表面所吸附的液体。这种液体与一般游离滴状液态水不同,它在自身重力作用下不可能自由移动,因而也不会从沉积物中脱离出来,只是由于沉积物的压密,孔隙体积减小才发生孔隙溶液的运动。实验室条件下采用压榨法或高速离心分离法可直接采集到这种溶液,因而又称之为压榨液。这与传统的通过水渍出液研究沉积物中可溶盐组分的方法是绝然不同的,由于水渍出液方法在制样过程中有外来 Porous solutions are liquids that are filled in the rock pore space and adsorbed on the surface of the solid particles. Unlike a free droplet of liquid water, this liquid can not move freely under its own gravity and therefore does not detach from the sediment, but only because of the compaction of the sediment and the decrease of the pore volume. exercise. Under laboratory conditions by pressing or high-speed centrifugation can be directly collected to this solution, which is also known as squeezing liquid. This is quite different from the traditional method of studying the soluble salt components in sediments by the water stain exudate,
