求翻译：以淀粉、胶态二氧化硅、硬脂酸镁为考察因素，每个因素取3个水平，用L9(34)正交表安排试验，以粉体流动性为考察指标，进行正交试验。是什么意思？

From starch, colloidal silicon dioxide, magnesium stearate factors, each taking three levels, l9 (34) orthogonal table arrangements test, powder fluidity index, the orthogonal test.

To starch, glue silicon dioxide (State 2, stearic acid and magnesium to visit each of the factors from the 3 level, 9 (34) L orthogonal table arrangements, in order to test for the visit powder mobility indicators, Q-pilot.

Take the starch, the colloid silicon dioxide, the magnesium stearate as the inspection factors, each factor takes 3 levels, with the L9(34) orthogonal array arrangement experiment, take the powder body fluidity as the inspection target, carries on the orthogonal experiment.

To study starch, colloidal silicon dioxide, magnesium stearate, take 3 each factor level (L9) orthogonal arrangement test, study with powder fluidity index, are orthogonal.
