In the thesis, the effects the acidity and alkalinity of electrolyte on degrees of starch oxidation were discussed and theoretically expound the reasons. 主要探讨了电解液酸碱性对淀粉氧化程度的影响,并从理论上解释了其原因。
The diatomite-modified-asphalt possesses strong stickiness after being mixed with stone stock of neutrality, acidity and alkalinity, and can be applied in the constructions of highway. 硅改沥青与中性、酸性和碱性石料混合后具有很好的黏附性，可用于公路路面铺设建设中。
The method hybridized can effect not only the bond length between two atoms and the acidity and alkalinity of its corresponding molecule but also the strong and weak of bonds in a molecule. 杂化方式影响分子的酸性与碱性；杂化方式也可影响分子键的强弱.
There are a series of ecological factors including temperature, water, oxygen, light, soil acidity and alkalinity, soil salinity, chemicals, sowing depth, and biology which affecting seed germination. 摘要种子萌发受到外界一系列条件诸如温度、水分、氧气、光照、土壤酸碱、土壤盐分、化学物质、埋深和生物条件等生态因子影响。
According to the great influence of system acidity and alkalinity on MCM41 molecular sieve formation in hydrothermal condition, a detailed formation mechanism of MCM41 was proposed. 在水热体系中，合成介质的酸碱性对MCM-41分子筛的生成有很大的影响，据此提出了MCM-41分子筛生成的详细机理。
