The static pressure gradient in cyclone air classifier can have influence on the test and measurement for its flow fields by five-hole probe.
用五孔探针测试旋流式气力分级机流场时，分级机内存在的静压梯度会对测试产生影响。
Furthermore, the total pressure along the flow direction reduces gradually, and the corresponding static pressure increases with small gradient, the maximum value occurs at the end of FADS.
沿着流动方向，空气全压均逐渐减小，静压则逐渐增大，但增幅不大，末端处静压复得现象较为明显。
