与目前制备生物降解颗粒方法相关的一个问题是表面活性剂和/或多溶剂的必要性，你知道包含什么事项吗？下面小编为您介绍。

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.

实际上，乳液法和溶液沉淀法都需要使用不止一种的溶剂和/或表面活性剂。而且在这些方法中可能使用的卤化溶剂会造成健康问题并且影响环境。因此，不需要使用表面活性剂和/或包括卤化溶剂在内的多种溶剂的制备生物降解颗粒的方法会是有益的，并且更节省成本。

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.

主要涉及制备生物降解颗粒的方法，并且涉及在地下应用中使用这些生物降解颗粒的方法。

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

在一个实施方式中提供一种方法，其包括提供可降解聚合物和一种溶剂，其中溶剂包含选自以下组中的含水流体淡水、盐水、卤水、海水、及它们的组合；

In one embodiment, a method is provided, which includes providing a degradable polymer and a solvent, wherein the solvent comprises an aqueous fluid, fresh water, brine, sea water, and a combination thereof, selected from the following groups:;
