一、段落翻译 Poly(vinyl alcohol) (PVA) is a water-soluble synthetic polymer. It has the idealized formula [CH2CH(OH)]n. It is used in papermaking, textiles, and a variety of coatings. It is white (colourless) and odorless. PVA is also degradable. PVA hydrogel could find applications in many areas of biomedical engineering including as a scaffold for tissue engineering and as a controlled release/drug delivery vehicle. 二、中译英 图1中所示为蛋白质与材料表面的相互作用 与传统材料相比,纳米材料表面对蛋白质的吸附有显著增加 SEM可以检测材料的表面形貌 该课题研究了PLGA支架的表面化学性质 表面活性剂可以稳定水/油界面
