| 1. | Aquifers have water contents over 30% . 含水层的水含过30。 |
| 2. | Groundwater recharges in aquifers . 地下水重新注入含水层。 |
| 3. | A confined aquifer is also known as a pressure aquifer . 承压含水层又叫压力含水层。 |
| 4. | The aquifer is unconfined locally and may be recharged . 含水层因为局部不承压而得到补给。 |
| 5. | Such material can confine water in an artesian aquifer . 这样的介质能把水控制在承压含水层中。 |
| 6. | One of the two main types of aquifer is the unconfined aquifer . 非承压含水层是两种主要含水层之一。 |
| 7. | Sometime the term artesian is used to denote a confined aquifer . 有时候人们也用自流含水层这一术语表示承压含水层。 |
| 8. | It describes unsteady flow toward a discharging well in an extensive aquifer . 它描述位于广阔含水层中的抽水井的非稳定流。 |
| 9. | An unconfined aquifer has a water table at its top and water in direct contact with the soil atmosphere . 非承压含水层在它的上面有一个潜水面且水与土壤大气直接相连。 |
| 10. | A problem which is often attacked by resistivity measurements is to locate the depth at which saltwater invades fresh water in aquifers . 经常用电阻率测量来攻克的问题是确定含水层中盐水侵入淡水的深度。 |
