【求助】求这段话的更好翻译

已翻译得挺好。

你的翻译已经很到位了。
我看了一下欧洲药典，对澄清与无色的定义是这样写的：
A liquid is considered clear if its clarity is the same as that of water R or of the solvent used when examined under the conditions described above, or if its opalescence is not more pronounced than that of reference suspension I.

A solution is colourless if it has the appearance of water R or the solvent or is not more intensely coloured than reference solution B9.

reference suspension, reference solution具体翻译成参照溶液还是标准溶液更好？
