| 1. | Suction devices are inadequate in gravels or very porous soils . 吸水装置对砂砾或非常疏松的土壤是不适用的。 |
| 2. | Seismic reflection and transmission coefficients at an air - water interface of saturated porous soil 气分界面上的反射与透射 |
| 3. | If this type of soil is not readily available try a light weight and porous soil 如果这类土壤不容易提供,试试轻质和多孔的土。 |
| 4. | As a result , a systemic study on shallow water flow over porous soil is of great importance both in theory and application to engineering 因此对于降雨条件下坡面水运动的研究无论在理论上还是在工程应用上,都具有十分重要的意义。 |
| 5. | The island has thick and porous soil and caves and cracks abound , making it an ideal habitat for pallas pit vipers , the only kind of snake found here , a rare ecological phenomenon 岛上土层深厚,土质疏松,洞穴和岩缝较多,最适于蝮蛇繁衍生息。蝮蛇是岛上唯一的一种蛇,这种生态现象世所罕见。 |
| 6. | This dissertation is based on biot ' s equations governing the behavior of saturated linear elastic porous soil under dynamic loads . on the basis of the existing work , two - dimensional biot ' s consolidation of layered saturated soils under variable loading is studied analytically and numerically 在前人研究的基础上,本文基于biot的动力固结方程,在方程推导中考虑了水土耦合项,用解析和数值方法研究了动荷载作用下地基的固结情况。 |
