[求助] 求翻译******

有个对我非常有帮助的实验步骤:PCL powders was dissolved in hexafluoroisopropanol under stirring for a few hours, obtaining a 3.5%
concentration. For composite fibers, HA or beta-TCP nanocrystals were added to the PCL/HFIP solution and put under stirring for one week, using
oleic acid (0.05% w/v) as surfactant in order to obtain stable particle suspension in the polymer solution. Three different solutions were prepared: 3.5% PCL, 3.5%–2% PCL-HA, 3.5%–2% PCL-TCP using HFIP as solvent (all the concentrations are expressed as w/w ratios in relation to the solution).不知道这个句子里边提到浓度到底是是什么浓度。自己能理解大部分意思,但是由于没什么实验经验,怕误解了其中的意思。希望大神们悉心回复。

不是说了嘛,是w/w. 也就是按质量比,比如5%,就是5g溶质和95g溶剂
