It was necessary that the frontispiece of face was pre-supported in the especial stratum. Fourthly, by the model analytic value and the FEM numerical simulation, the advance reinforcement parameters were analyzed roundly, and its results explained that the parameters had optimal values. A series of formulations conforming loads born up for pre-reinforcement structure were given, and five rules for its design and choice were put forward.

全面分析了影响工作面超前预加固参数的因素；揭示了拱部超前预加固参数与地层参数、隧道开挖与支护参数等的内在联系；论证了地层预加固参数的最佳值概念；给出了确定超前预加固结构作用荷载的半拱法、全拱法和全土柱法理论计算公式；建立了隧道工作面上覆地层稳定性判别的准则；提出了工作面地层预加固参数设计与选择的5个指导原则；最后给出了一整套确定浅埋暗挖法隧道工作面地层预加固参数的动态设计方法。

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。

We used a unique technology at the merge, where we pre-build slugs of product then pre-set the gapping of the product on the slug belts.

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。
