The optimum pH range for combined degradation was in weak acidic.
弱酸性环境有利于降解反应的进行。
When the optimum ph is about 10, the photoluminescence of the nanocrystalline defects weaken.
反应的最佳PH值应为10左右，此条件下纳米晶缺陷发光相对较弱。
The fermenting conditions such as initial PH, volume, inoculability quantity etc. were studied, and the optimum conditions have been found.
发酵条件考察初始pH、装液量、接种量等方面，确定了最适发酵条件。
