Systematic isopiestic measurements have been made at the temperature 298.15K for the quaternary system {water (A1)+methanol (A2)+sodium bromide + ammonium bromide} with the mass ratios of water: methanol=9∶1 and 4∶1 and for the quinary system {water (A1)+methanol (A2)+ethanol (A3)+sodium bromide +ammonium bromide} with the mass ratios of water: methanol: ethanol=18∶1∶1 and 8∶1∶1, which were the first isopiestic determining examples for mixed solvent systems.

本文系统地测定了298.15K时混合溶剂各组元质量比为w〓∶w〓＝9∶1和4∶1的四元系{H〓O+甲醇(A2)+NaBr+NH〓Br}和w〓∶w〓∶w〓＝18∶1∶1和8∶1∶1的五元系{H〓O(A1)+甲醇(A2)+乙醇(A3)+NaBr+NH〓Br}的等压平衡，是混合溶剂体系等压性数据的首例。

The problem was that the water pump could not pump in a nine-story residential building, as result the water would soon be used up. I arrived at night; found that liquid level relay broke down. then I installed a three-pole knife switch next to liquid level relay to power the pump manually, so the problem with no water to be solved provisionally. then I fitted the Level relay for them, finally the water pump can pump automatically again

有一次来电，物管说他们小区没有电工，说一幢9层的住宅楼一楼的水泵泵不上水，水池很快就会无水用了，晚上我到达现场，原来是液位继电器坏了，我当时已带上了三极的闸刀开关，在继电器的旁边装上闸刀开关，手动供电给水泵，临时解决了没水用的问题，过后才为他装上液位继电器，又恢复了自动泵水。

Water, he thought, hearing the soft splash of a lawn sprinkler; to taste the water of home, the full cool water of the valley, to have that simple thirst and that solid water with which to quench it, fulfillment, the clarity of life.

他听到草地上洒水装置轻微的洒水声，就想到了水；他要嚐嚐家乡的水，河谷里冰凉的水，口渴时喝下那种纯净的水就可以止渴，他会感到满足，也会感到生命的清澈。

This showed that capacity of water-holding in biological soil crusts were obvious improve,and effected precipitation permeate or water second distribute process.The study results of"fertile islands"formation mechanism in biological crusts showed that biological crusts layer cover could increased nutrients content for below sand soil through precipitation permeate washing,and it promoted plants assimilate more nutriment.The matter import ways of biological soil crusts fertility island had many ways,including the effection of living macrobiotics metabolism in crusts levels,wind-sand flow of near surface,dust deposition and plants decomposition course,etc.Source of particle matter in biological soil crusts was wind-sand flow of near surface,and not dust deposition.Biological crusts layer cover had preserved effection for nature water content in 0-5cm soil layer,compared with the sand of no biological crusts layer,effecting precipitation permeate,and could not obvious restrained from the water evaporate process indoor experiment.

生物结皮层肥岛形成机制的研究结果表明：生物结皮层覆盖能够通过降水淋溶作用而增加下层土壤养分的含量，进而促进植物对养分的吸收；生物结皮层养分输入有结皮生物代谢、降尘、风沙流和植物分解矿化作用等多(来源：A73e3B3eC论文网www.abclunwen.com)种途径，但生物结皮层的颗粒物质来源主要是近地表风沙流，而不是大气降尘；生物结皮层覆盖对0-5cm土层自然含水量有一定的保护作用，并影响降水向深层渗透，不能有效的阻止表层水分的蒸发进程；研究表明采取人工促进技术能够在流动沙丘上形成生物结皮层，实现流动沙地的快速治理。

目的 客观评价巢湖的氮、磷污染水平，正确反映该湖的富营养化程度，为该湖的水体污染控制及水质改善工程及同类湖泊的水质评价提供参考。

Applying this point to Jackson's argument, we can't move a priori from microphysics to the claim that water covers 60% of the earth because there is a world in which some of what counts as water is ghost water, so even if H2O covers 60% of the earth in that world, what they call 'water' will cover more.

用这一点在Jackson的论证上，我们不能从微观物理学传递先天性给'水覆盖60％'，因为有一个世界有些算作水的东西是水幽灵，所以，即使在那个世界H2O覆盖60％，他们称为"水"的东西会覆盖更多。

"An artificial cut was made from the river to bring the water at proper height to the water-wheel, and, in order to make sure of a supply of water at all seasons, the mill-owner usually built a weir across the river to hold back the water and so form an artificial reservoir."
