“盐垢”常见的英文表达是 “salt scale” 或 “scale deposits (caused by salts)”。
salt scale:简洁直接,在描述与盐相关的结垢现象时常用。例如:The buildup of salt scale in the pipes is causing blockages.(管道内盐垢的堆积正在造成堵塞。)
scale deposits (caused by salts):表述更详细,明确指出结垢物是由盐类造成的,在需要详细说明结垢成因的语境中较为适用。例如:Regular cleaning is necessary to remove the scale deposits caused by salts in the boiler.(需要定期清洁以去除锅炉内由盐类造成的结垢物。 )
