ring true
听来真实可靠
从前用金币、银币的时代，人们怕拿到的硬币纯度不参够，常会两枚互敲一下，听听声音是否清脆悠长。ring指的 就是敲击的声音，ring true这个动词词组是指硬币敲击声听 起来成色十足，引申为「（事情、说法等）真实可靠」。
Using computers,[insurance companies] scan [clientss claims] for such warning signs of fraud as services performed on weekends and holidays and visits to doctors far from a claimant’s home. That still leaves plenty of claims that ring true to a computer program only to prove false upon human investigation.(出自：TIME, Aug. 30,1993,p. 24 )
〔保险公司〕用计算机扫描检查〔客户的索赔〕，寻找一些诈欺的迹 象：例如周末假日还有服务，以及索赔者跑到离家很远的地方看 病等等。但还是有许多在计算机程序看来是货眞价实的索赔案，派 人调查时才露出马脚。
