Sieve diameter is the length of the side of a square sieve opening through which the given particle will just pass. 筛析粒径是指一个四方筛孔的边长,某已知的颗粒将恰好通过这筛孔。
The relationship for backmixing coefficient was given from the experiments on a Φ 1.2m sieve tray with Φ 10 mm hole diameter. The electropotential measurement proved to be practicable for the tracer stimulus-response technique. 通过φ1.2m冷模装置上的实验,给出φ10孔径大孔筛板的返混系数关联式,检验了电极电位法用于脉冲&响应技术的可行性。
The experimental result was that load input power changed less and consumption of electricity per ton increased and productivity decreased as moisture rates added under the same sieve pore diameter. 结果表明:对于相同筛孔直径,随着含水率的增大,负荷输入功率基本不变,吨料电耗增加,生产率降低;
After measuring the bubble diameters of common sieve trays and upper taper sieve trays, it is found that perforation structure has little effect on the gas bubble diameter and gas-liquid contacting area. 在同一测试条件下对普通筛孔和上锥形筛孔的气泡直径测试,得出筛孔结构的变化,并没有带来气泡直径的较大变化,也没改变气、液接触界面的大小。
On treating with base β molecular sieve had a small volume and diameter of secondary mesopore; 在碱性处理条件下,二次中孔的体积和孔径较小;
