术语“析因设计”的详细信息

英译术语:

factorial design

汉语语境:

文章采用析因设计的方法，研究沉积物水浸提液掺杂的多种重金属铜、镉、锌、铅和镍对发光菌的联合毒性。通过对试验结果进行方差分析和多元线性回归，建立了重金属浓度和发光菌发光抑制率的关系模型。模型分析结果表明:锌对联合毒性产生负的影响，铜、镉、铅、镍对联合毒性具有正的贡献；镉与锌的二元交互作用和镉、铅、镍，锌、铅、镍三元交互作用表现为协同作用，铜与镉、镉与铅、镉与镍、铅与镍二元交互作用表现为拮抗作用，而重金属四元和五元交互作用对联合毒性的贡献不显著。上述重金属联合毒性的作用可为沉积物中重金属复合污染控制提供参考。

英语语境:

Solution of aqueous extract of sediment samples was doped with a number of heavy metals, such as Cu, Cd, Zn, Pb and Ni. The experiment was conducted for the purpose of investigating the joint toxicity of multiple heavy metals to luminescent bacteria. This paper described the experiment in which the factorial design was used, and the experimental results were analyzed using variance analysis and multiple linear regressions, which led to a model that could depict the relationship between heavy metal concentration and the luminescent bacteria inhibition ratio. The modeling results showed that different groups of heavy metals (binary and ternary) have different synergetic effects on the joint toxicity to luminescent bacteria, which could provide references for the control and abatement of the heavy metal in water.
