The staticpressuregradient 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 staticpressure increases with small gradient, the maximum value occurs at the end of FADS.
