求翻译：DR磨损分析对柴油机油样的测量精度高于PQ磨损分析，指标为WPC（磨损颗粒总浓度），数值上等于大颗粒浓度DL和小颗粒浓度DS之和。是什么意思？

The dr Wear Analysis of the diesel oil sample measurement accuracy higher than the the pq wear analysis of indicators for the wpc (wear particles concentration) is numerically equal to the large particle concentration dl and the concentration of small particles ds and.

DR wear analysis of diesel oil as the accuracy of the measurement and analysis than PQ wear indicators (wear particles WPC for total concentration on ) and the value is equal to the particle concentration and particle concentration DL DS.

The DR attrition analysis is higher than the PQ attrition analysis to the diesel oil machine oil type measuring accuracy, the target is WPC (attrition pellet total density), value superior in big pellet density DL and sum of the finely ground particles density DS.

DR wear analysis on diesel engine oil wear analysis of measurement precision is higher than the PQ, indicators for WPC (total concentration of wear particles), the value is equal to the largest particle concentration on concentration of DS and DL and small particles.
