與目前制備生物降解顆粒方法相關(guān)的一個問題是表面活性劑和/或多溶劑的必要性，你知道包含什么事項嗎？下面小編為您介紹。

A problem related to the current methods of preparing biodegradable particles is the necessity of surfactants and/or polysolvents. Do you know what is included? Here is a brief introduction.

實際上，乳液法和溶液沉淀法都需要使用不止一種的溶劑和/或表面活性劑。而且在這些方法中可能使用的鹵化溶劑會造成健康問題并且影響環(huán)境。因此，不需要使用表面活性劑和/或包括鹵化溶劑在內(nèi)的多種溶劑的制備生物降解顆粒的方法會是有益的，并且更節(jié)省成本。

In fact, both the lotion method and the solution precipitation method require the use of more than one solvent and/or surfactant. Moreover, halogenated solvents that may be used in these methods will cause health problems and affect the environment. Therefore, a method for preparing biodegradable particles without using surfactants and/or multiple solvents including halogenated solvents would be beneficial and more cost-effective.

主要涉及制備生物降解顆粒的方法，并且涉及在地下應用中使用這些生物降解顆粒的方法。

The invention mainly relates to a method for preparing biodegradable particles, and relates to a method for using these biodegradable particles in underground applications.
