分级精度 meaning in Chinese

effectiveness of classification

The effect of the shape of particles , the density and velocity of feeding , grain size distribution and temperature to the efficiency and precision of classification were studied
通过实验来分析颗粒粒度分布、颗粒的形状、给料速度、料浆浓度以及温度对分级精度和分级效率的影响。
According to the effect of size distribution to classification , the idea of pre - classification and two times classification was proposed , which , to great degree , reduces the effect of tail flowing and drift flowing and improves the precision of classification
针对颗粒粒度分布对分级效果的影响提出了预分级和二次分级的思想，极大程度地减少了尾流和漂流的影响，同时提高了分级精度。
Abstract : in order to improve the performance of a vortex classifier , a certain type of narrow plates are fitted in the passages between the blades in the rotor cage . this measure results in reduction in the cut size and increase in classifying precision . more significant effect is observed in the case of the rotor cage with fewer blades originally fitted . it is pointed out that the reason is due to the decrease in inertia counter vorticity
文摘:在涡流分级机转笼通道中心加装窄叶片使产品分割粒径减小，分级精度提高.转笼径向叶数较少时加装效果明显，径向叶片数多时效果不明显.分析指出，这是减小了转笼径向叶片间惯性反旋涡强度的缘故
