1. The different influences of the capillary radius to the permeating speed and depth of concrete under different water pressure were investigated. 重点探讨在不同水压力作用下，毛细孔半径对混凝土渗透速率和渗透深度的不同影响。
2. Permeating and applying "limit" thinking method is helpful to simulate students' interest and strengthen their thinking and applied abilities in calculus teaching. 在微积分教学中渗透与应用“极限”思想方法，有助于激发学生的学习兴趣，增强思维能力和应用能力。
3. Pour the colorized permeating floor materials into the mixer. After 3-5 minutes mixing, add 2. 2 kilograms water for every 50 kg floor materials and then mix until the aggregate surface shines. 将彩色透水地坪料倒入搅拌机中，必须干搅拌3-5分钟后，每50公斤透水地坪料加2。2公斤水搅拌，到骨料表面发亮这才停机。
