分子筛孔结构和酸性对苯与丙烯烷基化的影响

The results show that under the conditions of soluble phosphates as the dispersants, the beating degrees of sepiolite fibers increase at first, then go to be stabilized with the enlargement of sieve pore diameters and the elongation of beating time;

结果表明，在以水溶性磷酸盐作为分散剂的情况下，随筛分孔径的增大和打浆时间的延长，纤维的叩解度先上升，然后趋于稳定；

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。

Two kinds of pre-disposal methods, filtrating by 80 sieve pore and filtrating by 150 sieve pore then centrifugalization, were applied to dispose the orange juice, respectively.

分别采用80目筛滤和150目筛滤后离心过滤两种方法作柑桔汁预处理。

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；

Base on the 4 standard combining ratios as the analysis objectives, to discuss how will the undulation of the critical sieve pore pass through that within the construction quality standard affect the quality of different bituminous mixture.

以4个标准配合比为研究对象，初步分析探讨了在施工质量检验级配范围内关键筛孔通过量的波动对不同类型沥青混合料质量的影响。

Studied smashing characteristic of corn straw, including mainly performance parameter of pulverizer such as consumption of electricity per ton, hammer patch thick and output per kW · h under the condition of different moisture rates, sieve pore diameter and hammer number.

对不同含水率、筛孔直径、锤片数量下玉米秸秆粉碎机的吨料电耗、锤片厚度及度电产量等性能参数进行了试验研究。

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。

The MCM-41 is a kind of new type molecular sieve of medium pore size with adjustable pore diameter and was developed by Mobil Company in nineties.

SRCC between SBB and sieve pore bug ( SPB, M. cribraria ) was 0.408.

豆突眼长蝽和筛豆龟蝽之间存在着显著的正协变, 相关系数为0.408,二者具有某种程度上的依存关系.

Results showed that PVDF membrane had stronger resistant pollution ability to orange juice filtrated by 150 sieve pore and centrifugalization than that by 80 sieve pore filtering.

结果表明：PVDF膜对150目筛滤离心过滤后的果汁表现出较强的抗污染能力；

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。

The result shows that crude ash removal effect for about 17% moisture, 4000 r/ min rotation speed and 8 mm size of sieve pore is the best and crude ash removal rate can reach 70.8% among which sodium sulfate removal rate is 34.7%.
