运用双位移传感器构成的系统可有效地测量塑料与金属配副时塑料的磨损量。
The twin displacement transducer system can measure effectively the wear of plastic against metal pairs.
测量系统要求金属配副磨损量应很小，甚至可以忽略，以确保结果的准确性。
In order to assure results correctness the requirement for system is that friction wear of metal pairs must be a little, even omitted.
精加工强调的是精度——使用非常锋利的刀具，切除的金属量较少，测量时的精密度要求较高。
The emphasis here is refinement - very sharp tool, comparatively little metal removed, and a higher degree of accuracy in measurement.
