查询词典 salinity indicator

The results showed that the temporal-spatial distribution pattern did not alter basically from May 2002 to May 2006, and the topsoil congregative type of soil salinity profiles was the majority in the Yellow River Delta, which indicated that the risk of soil salinization was great, and the level of amelioration and rational utilization for saline soils needed to be improved further in the Yellow River Delta.

结果表明：从2002年到2006年，该地区土壤盐分剖面类型的空间分布格局基本没有改变，黄河三角洲土壤盐分剖面类型总体以表聚型为主，这表明黄河三角洲土壤盐渍化风险大，必须进一步提高盐渍土的治理和合理利用水平。

构造相对活跃期为沉积水体咸化期，主要发育扇三角洲平原亚相的辫状河道粗碎屑岩，同生期胶结作用强，而浅埋藏早成岩阶段碳酸盐和硫酸盐胶结物充填强烈，致使物性进一步变差，并且不利于晚成岩A阶段的溶蚀作用进行。

Soil salinity is a severe global problem, nearly 10% of the total land surface is coved with different types of salt affected soils.

土壤盐渍化对农林业的影响是一个全球性的问题，全球20％的耕地和近半数的灌溉土地都受到不同程度的盐害威胁，所以植物抗盐育种一直是研究热点。

Azoreductase in E.coli.JM-109 can damage -N=N- to decolorize azo dye. Decolonization conditions,such as dye categories,temperature,pH,salinity,oxygen were studied in this article.E.coli.

由于E。 coli JM-109含有的偶氮还原酶能破坏偶氮染料的-N=N-使其脱色，因此本文考察了其脱色的条件（温度，pH，盐度，供氧量）及其适用范围。

而在高土壤盐度时，通过其盐腺泌盐达到避盐目的。

The results obtained from experiment for salt resistance showed that Distichlis palmeri Vs., which could grow at the soil salinity of 3.97-10.97 g/kg, was of strong salt resistance.

对帕尔默盐草的耐盐试验表明：该草具有较强的耐盐性，能在土壤含盐3.97-10.97 g/kg范围内生长，且在较低土壤盐度(3.97 g/kg)下有利于地下根茎的分化和新茎的形成与生长。

在我国干旱、半干旱地区和盐碱地区约占国土面积的一半以上，仅次于病虫害造成的损失，严重制约着这些地区的粮食生产。

At the same time the rain is not aboundance enough to eluviate salinity of the earth's surface .

因此，土壤中以上升水流占绝对优势，水分垂直运动比较强烈，地下水将土壤中的盐分带至地表，造成表土层强烈积盐。

By simulating river plume evolution under the combined action of tide and estival wind field averaged over many years, we have found that the modeled salinity distribution is consistent with the observed one rather well, which means the river plume develo

通过检验河流羽流在潮汐和渤海夏季多年平均风场共同作用下的发展特征，发现计算得到的表层海水盐度分布与实测值相当吻合，因此可以认为河流羽流发展对于渤海夏季盐度分布起着重要作用。

Above the high tidal flat and lowland strata of MIS 3, the marine microfossils continuously or discontinuously occur at some horizons of estuary facies and neighbor lowland, even during the Last Glacial Maximum, but only of the euryhaline and low-salinity assemblages generally, which do not extend far from the paleo-river.

在MIS3阶段高潮坪一低地沉积之后，河口与相邻低地依然持续或断续出现海相微体生物，个别钻孔中其分布甚至延续到末次盛冰期低海面地层中，但是基本都是广盐种和低盐种。

The system can be widely used in belt weighing and batching process control,etc.
