sedimentation number

This paper reported the detective result of the microbe number in the sterile laboratory and the super clean bench by plate sedimentation analysis. Before test, the laboratory had been irradiated with UV rays for 45 minutes and treated with air purification system for 30 minutes.

洁净实验室经紫外线照射45min后，开启空气净化系统30min，用平板沉降法测定洁净实验室及净化工作台内净化空气沉降菌数。

Correlation analysis indicated that there were no significant relationships between sedimentation and head length, spike number, 1000 seed weight and seed plumpness, but positively significant with seed horniness ratio.

对国内外60个品种的分析表明，沉降值与穗长、小穗数、千粒重、子粒饱满度相关性不明显，与子粒角质率呈极显著正相关。

According to the shallow pool sedimentation theory and Stocks formula, the length, width, and the space between the plates are calculated and selected, meanwhile Renault Number being used to assure laminar flow.

以斯托克斯公式和浅层沉淀理论为依据，进行板长、板宽及板间距的选择，并以雷诺数验证水流的层流状态；
