In this paper, a new method, pre-crosslinking control method, has been developed for controlling the pore structure of carbon membrane. By this method, the pore structure of carbon membrane was controlled by adjusting the fusibility of resin through varying the hexamine content used in the pre-crosslinking treatment.

在实验过程中，发现了一种调控微滤炭膜孔径的新方法，即通过改变预固化过程中六次甲基四胺的用量来控制预固化程度，从而改变成膜树脂粒子在炭化过程中的熔融特性，实现对炭膜孔径的调控，同时影响炭膜强度。

Directed against the existing problems in traditional mixing process, secondary mixing techniques, such as pre-mix cement mortar, pre-mix cement paste, sand enveloped with cement paste, coarse aggregate enveloped with cement paste and aggregate enveloped with cement paste are discussed, and the effect of different mixing technological processes on concrete mixing quality is studied. The homogeneousness, compression strength of concrete and the power consumption are tested during the test, and compared with the traditional mixing method.

针对传统混凝土搅拌工艺中存在的问题，讨论了先拌水泥砂浆法、先拌水泥净浆法、水泥裹砂法、水泥裹石法、粗细骨料全造壳法等二次搅拌工艺，研究了不同工艺流程对混凝土搅拌质量的影响，测试了不同条件下混凝土的匀质性、抗压强度指标及功率消耗，并与传统搅拌工艺进行了对比试验。
