The single factor experiment obtains the synthesis optimum condition is: Temperature 30 ℃,time 3 h,initiator amount used 0.

Methods Three main factors including concentration of solvent,time and ratio of solid to liquid were investigated by using single factor experiment.

Taking 6 major components of soybean isoflavones,daiazin,glycitin,genistin,daiazein,glycitein and genistein,as the contrast,comparing single factor experiments and orthogonal experiment,The optimum condition to extract soybean isoflavones from the defatted soybean meal was studied,which provide a frame of reference for the industrial-scale production of soybean isoflavones.

Extracting gypenosides by enzymatic method was studied by single factor test and orthogonal test.

Based on selecting MDEA solution as absorbent and hollow polypropylene fiber membrane as a device,single factor test was designed to test influencing factors of membrane-based gas absorption efficiency of H2S removal.

Influence of several experimental factors on morphine dependence model in rats;

In order to optimize the Hot Mix Asphalt s(HMA) aggregate gradation,improve the pavement anti-rutting performance,and prolong the pavement life,through single-factor-skeleton-dense-test and Bailey method,the optimal framework structure of gabbro AC-16 gradation was got by analyzing the effect of the aggregate content,CA ratio,passing percent of the key sieve to the gradation s skeleton.
