1·It will increase sharply with the decrease of the diameter of sieve pore.
随着筛孔直径的减小，压力梯度大大增加。
2·Therefore produce good condition and make the materials smaller than the output granularity, especially the big-density materials and pulp get through the sieve pore together.
从而造成了较好的分离条件，使小于分离粒度的物料，特别是比重大的物粒和矿浆一起透过筛孔成为筛下产物锤式粉碎机。
3·The sieve plate and sieve-pore completely formed lately.
筛板和筛孔的分化较晚发生完全。
4·The silicoaluminophosphate molecular sieve(SAPO-5) with relative bigger pore diameter was synthesized hydrothermally and the optimum synthesis condition was determined through experiments.
采用水热法合成大孔径硅磷酸铝分子筛（SAPO-5），并通过试验确定了SAPO-5分子筛的最佳合成条件。
5·The molecular sieve MCM-41 with different pore diameters is synthesized with Cetyltrimethylammonium bromide (CTAB) as the liquid crystal template and 1, 3, 5-trimethylbenzene (TMB) as assistant agent.
以十六烷基三甲基溴化铵(CTAB)为表面活性剂，以1,3,5 -三甲基苯(TMB)为辅助剂，合成出了不同孔径的MCM - 41介孔分子筛。
6·A novel small pore (metallo) aluminophosphate molecular sieve is disclosed.
公开了新型小孔(金属)铝磷酸盐分子筛。
7·The catalyst provided by the invention is obtained by the method that the surface acidity and the pore structure of a metal modified zeolite molecular sieve are decorated by siloxy group compound;
本发明所提供的催化剂由金属改性后的沸石分子筛再经硅氧烷基化合物修饰表面酸性和孔结构得到；
