中性介质

A method called " k - ratio h - point standard addition method " was proposed for the simultaneous determination of nitrate and nitrite , based on their ultraviolet absorption spectrum in a neutral medium
摘要研究了在近中性介质中，硝酸根与亚硝酸根的紫外吸收光谱，提出了引用“ k比例h点标准加入法”同时测定了硝酸根、亚硝酸根含量的方法。
It revealed that hexagonal structure was easily synthesized in the neutral medium , and lamellar structure was inclined to prepare under basic condition , and from the cooperative charge density matching mechanism and function of manganese iron and template molecular , the alkalescence influence on the structure was explained , and appropriate neutral hexadecylamine ( hda ) availed to synthesis of mesophase with more ordered degree for the mediation of packing parameter
通过水热合成方法对锰氧有序相的合成进行初步研究，探讨合成工艺对有序结构的影响：在中性的条件下，易合成六方有序结构产物；在碱性条件下，更易合成层状结构产物。并从电荷匹配的原则及锰离子与模板剂间键合作用解释了碱量的多少对合成产物结构的影响。
