易错句子The technician mixed two resolvent in the beaker.
正确表达The technician mixed two resolvents in the beaker.
resolvent 是可数名词，前面有基数词 two 时须用复数形式 resolvents；汉语名词无复数标记，容易漏加 -s。
solvent 是日常和化学中的常用词，主要作名词指“溶剂”，也可作形容词表示“有偿付能力的”；resolvent 极罕见，除“溶剂”外还用于医学“消散剂”和数学“预解式”。日常说“溶剂”应优先用 solvent。
dissolvent 与 solvent 近义，都指能溶解其他物质的介质，但 dissolvent 更少见、更书面；resolvent 同样罕见，且含义更偏医学和数学。一般化学语境中 solvent 和 dissolvent 都可成立，resolvent 则不是首选。
resolver 指解决争端的人，或把域名等解析成地址的程序；resolvent 不表示“解决者”，它指溶剂、消散剂或数学中的预解式。不要把 -er 结尾的 resolver 与 -ent 结尾的 resolvent 混用。
