英语好的朋友，能帮我翻译几句话吗？对我很重要啊，谢谢了o(∩_∩)o

In this paper, orthogonal design of yeast growing conditions have been studied to explore the effects of temperature, PH, sugar concentration, liquid volume on the impact of the growth of yeast. And determination of yeast in the medium PH natural conditions, the sucrose concentration of 2% liquid volume 2 / 5, culture conditions 30 ℃, shaker speed 180r/min of the growth curve.

The main body of a book has adopt orthogonality to test law , has been in progress to saccharomycetes's growth condition studying, effect having discussed the temperature , PH , cane sugar thickness , holding liquid amounts with growing to saccharomycetes. And determine yeast under natural culture medium PH condition, cane sugar thickness 2%, holds liquid amounts with 2/5, train condition 30 ~C, table concentrator rotation rate 180 r/min growth curves.
