查询词典 general test

The results of magnesium and calcium ions tolerance test indicated that the modified SPS, synthesized from the above two methods,has good chelation with magnesium and calcium ions for the crablike carboxyl and ester group and increase the reaction weight with magnesium and calcium ions for addition of hydrophilic group.Both of the two modified petroleum sulfonates could produce ultra-low interfacial tension at calcium and magnesium ions concentration lower than 600 mg/L,whereas the general petroleum sulfonates could only produce ultra-low value below 300 mg/L.

耐钙镁离子能力测试结果，以大庆炼化公司两种渣油为原料，采用上述两种合成方法制备的改性石油磺酸钠，由于产物中引入蟹爪状羧酯基，对钙镁离子有较强的螯合作用，同时增加了亲水基，增大了表面活性剂分子与钙镁离子的反应量，因而在600mg/L的钙镁离子溶液中获得10-3级的超低界面张力；而普通石油磺酸钠仅能在300mg/L的钙镁离子溶液中获得超低界面张力。

Relationship between DNA content and evolutionary degree DNA contents of bivalves were analyzed statistically with SPSS software at subclass, order, family and species grade respectively. Significant difference was detected between mean values of two subclasses according to the result of T-test. The DNA content of Heterodonta (3.77pg) was distinctly larger than that of Pteriomorphia (3.14pg). It was concluded based on ANOVA that the general trend of DNA content was to change from lower to higher values associated with evolution at higher taxonomical classification, i.e.

核DNA含量与进化地位的关系运用SPSS统计软件，在亚纲、目、科以及种4个分类等级上对双壳贝类的核DNA含量进行了统计分析。T检验结果显示，两亚纲核DNA含量的平均值有明显差异，异齿亚纲的核DNA含量平均值(3.77pg)显著大于翼形亚纲(3.14pg)，该结果表明，核DNA含量在较高的分类等级，即亚纲上表现出随着进化地位的升高显著增大的趋势。
