The effect of treating conditions, including the size of coal, treatment time, the ratio of acetic acid and hydrogen peroxide and microwave radiation power on the rate of desulfurization were studied by single factor method.
The effect of cutting parameters on cutting force, cutting temperature, tool life, wear mechanism and surface roughness is studied and analyzed by single factor process.
The extraction conditions were firstly optimized by single factor experiments.
While single-factor studies have yielded considerable insights, multi-factor manipulations have gained momentum recently.
The working conditions of CCPUE were studied by single-factor experiment design and the results showed that the optimal conditions were: initial temperature 25 °C, methanol to triglyceride molar ratio 10 1, flow rate 200 mL/min, catalyst content 1.8%, ultrasound working on-time 4 s, off-time 2 s, total working time 50 min.
There is consensus, furthermore, that this decline is not brought on by a single factor but rather by a multiplicity of factors acting synergistically.
In this study, the SE was prepared by the injection method and optimized by the single factor test and uniform design.
Studies suggest that neurotoxicity is not caused by a single factor but that it appears to be regulated by a number of factors including apoptosis, oxidative injury, DNA damage, mitochondrial dysfunction, and neuroinflammation [ 14– 14].
The percentage of variance (48.11%) explained by this single factor is even better than the one obtained in the original validation study [ 18].
In several of the industries with large wage gaps that she has studied, the difference in pay rates is explained largely by a single factor: These industries — the legal and finance professions, for instance — tend to more richly compensate people who are willing to work long, inflexible hours.
