💬 双语例句
OBP is produced when a special additive is mixed with a normal polymer. The additive (produced by a company where I am a director) dismantles the molecular structure of the polymer at the end of its useful life and enables natural decomposition in an open environment.
生产OBP只需要在普通聚合物中加入一种特殊的添加剂。 这种添加剂(由我担任董事的公司生产)会在聚合物使用寿命终点拆散其分子结构,使之能够在开放环境中自然分解。
The first step was to select monomers – a polymer’s building blocks – that would be safe in the human body. We then synthesized these polymers and discovered that by changing their composition, we could make them last in the body for a period ranging from days to years.
为证明这项原则,我们决心为医用目的合成一种叫聚酸酐的生物分解高分子全新系列材料。 第一步是选择单体 — — 即聚合物的建筑模块 — — 并确保在人体之中的安全性。 之后我们合成了高分子聚合物,并发现通过改变聚合物的构成,我们可以让它们在体内维持几天到几年不等的时间。
