The plating conditions show great influences on the P content of the coatings and thus the corrosion resistance.
在考察镀覆条件对镀层含磷量影响的基础上,用电化学方法评价不同含磷量镀层的耐蚀性,得到基本一致的结果:镀液温度及pH值降低,镀层磷含量升高,而镀层含磷量的提高又使镀层的耐蚀性提高。
For example,the P content of the degumming oil is difficult to reach 200 mg/kg by pure water degumming,and even if the P content in the oil is less than 200 mg/kg,the specification of the oil can′t reach the 280℃ heating test.
对于不同产地和不同季节的大豆,其磷脂的组成和特性存在差异,如单用水化脱胶,脱胶油含磷量很难达到200 mg/kg以下,即使脱胶油含磷量低于200 mg/kg,但280℃加热试验不合格。
The results are as follows: water stress does not reduce phosphorus content of aerobic rice root,on the contrary,that of the severe water stress increased at vegetative stage and reproductive stage.
研究了4种灌溉水平的旱稻磷素效应和水分生产率,结果表明:水分胁迫并未降低旱稻根系含磷量,而且在严重水分胁迫下有所增加,但根系磷素累积量在营养生长阶段-30 kPa水分胁迫处理显著低于-10 kPa处理,中后期随水分胁迫程度加深而降低。
Significant correlation was found between the increment and phosphorus content of the leaves of Eucalyptus urophilla, Pinus elliottii and Cunninghamia lanceolata .
应用改革后的氢氧化钠－草酸钠沉淀法和快速法，测定尾叶桉、湿地松和杉木林地土壤有效磷与林分各生长量及叶片含磷量的相关性，均明显地高于几种常规方法；测定广东省３０００多个各种类型林业土壤有效磷，均具有检测灵敏度高，不出现零值，脱色好，操作方便的特点，且与土壤全磷和有机质的相关性高，具有普遍的适应性；对测定全国３００多个各类型的酸性、中性和碱性林业土壤有效磷的结果，亦说明沉淀法和快速法可以测定酸性、中性和碱性各种类型林业土壤有效磷，特别是对测定南方以酸性土为主的各类型林业土壤有效磷效果更好，方法更为合适。
