分子筛脱蜡评价实验中正构烷烃含量的测定

The ratios of the pressure gradients measured in the test to that predicted by Poiseuille equation are about 2& 4 for the five kinds of diame-ters of sieve pore. Additionally, a simulating test of the pores being partly plugged has been performed.

在本实验的五种筛孔直径下，压力梯度的实测值与按Poiseuille公式计算的理论值之比约为2&4。
