求翻译：PQ磨损分析（Particle Quantifier index）可以测定油样中大尺寸的铁磁性磨损金属的浓度，用PQ指数表示，数值越大说明油品中磨损金属颗粒浓度越高，磨损情况亦越严重。是什么意思？

The pq wear analysis (particle quantifier index) can determine the ferromagnetic wear metal concentration in the oil sample size, pq index, the greater the value the higher the concentration of metal particles in oil wear, the wear of the more serious.

Wear analysis PQ Particle Quantifier index ( ) oil samples can be measured in large size ferromagnetic wear metal concentrations, with PQ index indicates that the higher the value, the oil products in metal wear particles the higher the concentration, the more serious wear also.

The PQ attrition analysis (Particle Quantifier index) may measure in fixed oils type great size ferromagnetism attrition metal density, indicated with the PQ index, in the value bigger explanation oil quality wears the metal pellet density to be higher, wears the situation to be also more serious.

PQ wear analysis (Particle Quantifier index) in the determination of oil concentration of large-size ferromagnetic wear metal, use PQ indices, higher numbers indicate higher the worn metal particles in oil, wear the more serious.
