The illusion works with mechanical force, call it friction, wearing away at the sensibility.
感觉上，这幻象以机械的力量，所谓的摩擦力、磨损的物理力量运作著。

The study of wearing rules and mechanical fault diagnoses is based on wear particle analysis.
磨损规律和机械故障诊断等研究都离不开磨粒分析技术。

High Reliability: The seal contains a simple, permanent magnetic structure and a non-wearing magnetic fluid. The only parts subject to mechanical wear are self-contained ball bearings.
