释义 | salinity noun[ U ] chemistry, medical specializeduk /səˈlɪn.ə.ti/ us /səˈlɪn.ə.t̬i/ the fact of containing salt of the amount of salt contained in something: 盐浓度 You should test the salinity of the water.你应该测试水的盐浓度。 very high salinity levels非常高的盐浓度 See saline These crops could grow in areas affected by salinity. The water was carefully controlled for temperature, salinity and acidity. The ongoing drought has increased the salinity of the estuaries. Water in general aquatically aqueous bathwater bathymetric bathymetrically bathymetry brackish briny distilled water grey water hydrosphere hydrospheric hypersaline hypersalinity non-turbulent overwater salt water soft water storm surge wet salinity | American Dictionarysalinity noun[ U ] us/səˈlɪn·ɪ·t̬i, seɪ-/ chemistry, earth science a measure of the amount of salt dissolved in water, esp. sea water Examples of salinitysalinity The density after this adjustment depends only on temperature and salinity, and it is referred to as the potential density. These simulations also demonstrate that salinities are probably high, which would restrict life to extreme halophiles. Most larvae of the above mentioned bird parasites are found in areas of lower salinity and can complete therefore their life cycle in brackish waters. The perturbations to both the temperature and the salinity are dominated by the z-independent terms. On the other hand, the presence of homogeneous layers introduced step changes in salinity at the upper and lower boundaries of the gradient region. In the second salinity experiment, there was no relationship between salinity treatment and mortality. The use of saline drainage water for irrigation creates soil salinity due to the accumulation of soluble salts in the absence of adequate leaching. Effects of drought and salinity on heterotrophic nitrogen fixing bacteria and on infection of legumes by rhizobia. Since the emergence pattern of marine trematodes has rarely been studied, the role of salinity is poorly elucidated. The movement away from intensive cereal monoculture systems could lead to a reduced incidence of water-induced degradation problems, such as salinity build up. Over the years different instruments have been developed for sampling the most important environmental variables (salinity, density and temperature) but each has its own limitations. For conservation programmes involving reseeding, we have identified germination protocols that will ensure very high levels of germination even at full salinity. The infection process of mullets with these cercariae is discussed in relation to salinity conditions prevailing in a brackish water stream. The up-estuary, tidally averaged salinity increases with increasing tidal range and decreasing run-off. Extreme salinity levels feature biota dependent upon "abnormal" conditions, which may represent forms of life that could possibly inhabit extraterrestrial planets.
