saline concentration meaning in English
含盐浓度
Examples
- The saline concentration in the 0 - 40cm layer will produce desalination trend in the 2010 . however , the saline concentration in the 40 - 70cm will be slightly accumulated
总体上节水改造工程对灌区浅层土壤盐碱化改善与防治有积极效果，但中层仍存在潜在盐渍化的可能。 - Based on five years regional water - salt monitoring data and related hydrological and weather information in the smaller scale experiment zone ( shahaoqu ) , the regional water - soil ( salt ) environment regime including grounder water table depth , water quality , superficial layer ( 0 - 40cm ) and middle layer ( 40 - 70cm ) soil moisture and saline concentration are simulated , tested and predicted using bp model . at the same time , the rbf model is be used to calibrate the results of bp
以一个小尺度试验区的多年区域水盐监测资料及水文气象资料为建模依据，对试区非冻期(作物生长期)的地下水位、地下水质、土壤水盐( o - 40cm ， 40 - 70cm )的水-土(盐)环境状况进行了较为深入全面的模拟预测，并进行了rbf模型预测结果的对比。 - Effects of diverse environmental factors on the growth rate ( od4oo ) and nitrogenase activity ( ara ) of the strain w12 hi nitrogen - free culture were investigated in our experiments . the results implied that the strain w12 could easily adapt to different cultural conditions : it could use various carbon sources ( especially glucose , sucrose , malic acid , mannitol ) , propagate quickly and fix nitrogen at a temperature range of 15 ? to 40 ? and at 25 - 35 ? for optimum , at a ph range of 4 to 8 . 5 , at a saline concentration range of 0 . 01 % to 1 . 5 % ; low nlv " concentration had little effect on its nitrogenase activity . ara could also be detected when it grow in the culture media with 5mmol / l ntv "
W12菌株对环境因子的适应性研究：无氮培养条件下，测定温度、碳源、酸碱度、渗透压对w12生长及固氮能力的影响，结果表明，在15 - 40下均能生长并表达固氮酶活性，其最适生长及固氮的温度为25 - 35 ；能利用葡萄糖、蔗糖、苹果酸、甘露醇等多种碳源生长并固氮，当培养基中同时存在蔗糖和苹果酸时，细菌生长和固氮活性最强；在偏酸和偏碱的条件下( ph4 . 5 - 8 . 5 )均能保持较强的生长势和较高的固氮酶活性，并能通过调节自身代谢平衡并适应环境的酸、碱性变化，使培养液趋于中性：能耐受较高的渗透压，培养液中卜、 5 naci浓度对其生长和固氮酶活性影响不大，当naci浓度升至2时，菌株的生长势及固氮酶活性才有所下降：低浓度的铰对其固氮酶活性影响不大，在0 - But , when the total water quantity is reduced 30 % of present average amount in the 2010 , the total salinity of groundwater will have significant increase in the different period ( pre - summer irrigation , post - summer irrigation , pre - autumn irrigation and pre - freezing up of soil four periods ) . the water quality will be likely to deteriorate ; in addition , the prediction models of soil moisture and saline concentration are established
通过试区土壤水分、盐分的bp与rbf模型的模拟与检验，预测了2005年、 2010年夏灌前、夏灌后、秋浇前与封冻前的土壤水盐状况，得出上壤水分随着灌水量的减少呈下降趋势，而土壤盐分在浅层与中层呈现出不同的结果： oa
