The beautiful scene described in a poem "mountain overlapping mountain, path around path, springs jingling and trees unexhausted." reappears this winter.

She dwelt among the untrodden ways / Beside the springs of Dove.

她住在人迹罕至的荒村，/在鸽子泉的岸边。

With the land use change and the enhancement of human activity, the groundwater pollution index rises from the indirect recharge area via the direct recharge area to the discharge area. The same variation happens from upper reaches to lower reaches in Daxin river basin, a typical karat area in the east of Jinan spring basin where the patterns of land use and human activity changes apparently. There is a close relationship between the groundwater and land use change and human activity.

伴随土地利用方式的改变和人类活动强度的空间变化，地下水质从间接补给区、直接补给区到泉水排泄区，单项污染指数和综合污染指数依次升高；具有典型代表性的泉域东部大辛河流域，从上游、中游到下游，地下水污染物的浓度也渐次升高，且愈往下游污染物浓度增幅愈大，显示出与土地利用方式和人类活动的密切相关性。

Growing disdain among consumers for water packaged in plastic has hit sales of Vittel, Perrier and Poland Spring while many of Nestlé's competitors - most recently Cadbury and Mars - are signing up to certification schemes such as Fairtrade and Rainforest Alliance.

消费者对塑料包装饮用水越来越反感，已经影响了Vittel、巴黎水和波兰泉的销售。另一方面，雀巢的许多竞争对手都签署了公平贸易和雨林联盟之类的认证计划，最近的就有吉百利和玛氏。

This study shows that there are 4 kinds of volcanic facies in deep volcanics in north Songliao Basin: eruptive facies, overflow facies, volcanic vent facies and volcanic sedimentary facies. There are 4 volcanic eruption cycles: Huoshiling period, Shahezi period, Yingchengzi period and Quantou period. There are 4 structural evolution stages: north-south accumulation, west-east subduction, uplift mantle and thin crust, alternative open and close. There are 4 kinds of pool-forming patterns:(1) pattern with the migration along the unconformity and fault to the near crater;(2) pattern with the migration along unconformity and fault to the rift margin;(3) pattern with the migration along unconformity, fault and fracture to the source rock;(4) pattern with the migration of the deep gas along the deep and large fault to the volcanic trap.

研究认为，松辽盆地北部深层火山岩主要存在四种火山岩相：即爆发相、溢流相、火山通道相、火山沉积相，划分为四个火山喷发旋回：即火石岭期、沙河子期、营城子期、泉头期，经历了四个构造演化过程：即南北夹攻、东西俯冲、幔隆壳薄、开合交替，具有四种成藏模式：即沿不整合面和断层运移至近火山口处火山岩圈闭聚集成藏模式、沿不整合面和断层砂岩疏导层运移至断陷边部火山岩圈闭聚集成藏模式、沿不整合面及断层、裂缝运移至源岩区内凹中隆火山岩圈闭聚集成藏模式、深部无机成因天然气沿深大断裂运移至火山岩圈闭聚集成藏模式。

The life of the desert aborigines is one of continuous movement from one water-hole to the next and they seldom remain in any one place for more than a few days.

在澳洲，生活在沙漠地区的土著人是一个跟着水泉不断迁移的人群，他们在一个地方的滞留时间很少超过几天。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
