Water quality - radiological methods - measurement of gross alpha activity in non - saline water : thick source method 水质.第3部分:放射性法.第1节:不含盐的水中总活度测量:厚源法
For na4edta , and the effect of ionic strength on the chelating properties of na4edta and na2edta for caso4 was reviewed 考察了含盐量对na _ 4edta和na _ 2edta溶解硫酸钙性能的影响。
The massive quantities of salt water can further contaminate soils , rendering them unsuitable for many crops 大量含盐海水的涌入,可使土地遭受进一步污染,使其不适合种植多数作物。
The water quality modelling results indicate that the predicted concentrations of salinity from the desalination plant discharge 水质模型结果亦显示预计来自化淡厂的排放的海水含盐量
The most saline of africa ' s large lakes , turkana is an outstanding laboratory for the study of plant and animal communities 图尔卡纳湖是非洲含盐量最高的大湖,它为研究动植物种群提供了良好的环境。
3 the salt - resistant characteristic which is adapt to poisonousness of salt hydronium , such as salt - gland , crystal cell , and soon 适应盐离子毒害的抗盐结构特征。如盐腺、含盐液泡包、含晶细胞等。
The results made clear that soil salt increased after saline water infiltration and decreased after fresh water infiltration 结果表明,不同轮灌条件下,土壤含盐量随灌溉咸水而增加,随淡水灌溉而降低。
Bifacial leaf and mesophyll tissue contain crystals , phloem is rich in saliferous vacuoles , and the mechanical tissue is developed 异面叶,叶肉组织中含有晶体,韧皮部内富含含盐液泡泡,机械组织发达。
It is used for quality control in research and clinical laboratories . it can be used to check and maintain stock solutions and dilutions 手持盐度仪是为测量氯化钠盐溶液含盐食品及海水盐水的浓度而设计的。
