求翻译：因此，在在乳化剂用量和助乳化剂用量相同的情况下，最大增溶水量下降。制备微乳化柴油的温度应在室温条件下制备20℃。是什么意思？

Thus, in the amount of emulsifier and emulsifier in the case of the same amount, the maximum solubilization of water down. Preparation of micro-emulsified diesel fuel temperature should be prepared at room temperature under 20 ℃.

Therefore, in and helps in the emulsifier amount used same situation in the emulsifier amount used, most increases dissolves the water volume to drop.Prepares the micro emulsified diesel oil the temperature to be supposed to prepare under the room temperature condition 20℃.

Therefore, emulsifiers and Emulsifying agent dosage the same case, the maximum solubility of water fall. Preparation of micro-emulsified diesel preparation under the temperature should be at room temperature is 20 degrees centigrade.

So, in a situation that and helps emulsifier consumption to be the same in emulsifier consumption, heighten the amount of water dissolved to drop most. Preparing the temperature of emulsifying the diesel oil a little should prepare 20 ℃ under the conditions of room temperature.
