And the rafted processing included two stages, one of which was the directional connect of the γ′ particle, and the second of which was the planing process of γ′ piece.

筏形化的过程包括两个阶段，一是γ′粒子的定向连接阶段；二是筏形γ′片层的平坦化。

The width and direction of rafted γ′ piece were closely related to original size and the crystal orient of γ′.

筏形化γ′的初始片层厚度及筏形化方向主要由γ′原始尺寸及晶体取向决定。

Saccharified bran was produced by thick layer and aeration solid fermentation of Aspergillus niger HS-16 with bran as raw material.

利用黑曲霉Aspergillus niger HS-16菌株作生产菌，麸皮为原料，采用厚层通风固体发酵工艺糖化麸皮，使麸皮的还原糖含量从2.8g/100g增加到糖化后的39.0g/100g，为红曲霉M-1菌株利用麸皮制备红曲麸增加了可发酵碳源。

Based on present researches,by means of modern measurement and analysis techniques,systemic laboratory experiments,field investigations and through theory researches were conducted.And following are the major points and achievements presented in this dissertation:①The micro-convexity on fracture plane was studied.Analyzing and comparing the static attribute and dynamic variation of natural fracture with the artificial,untreated fracture,artificial and scabbled fracture as well,making out the criteria that artificial and scabbled fracture simulate natural fracture.②We take the effect of all the three primary stresses and stress invariant into account in the Lade-dbl yield criterion,which can preferably reflect all the yield and destruction characteristic of the rock material.

结合裂缝性储层应力敏感性研究现状，利用现代化测试手段，通过系列的室内实验以及深入的理论探讨，本文取得的研究成果包括以下几个方面：①从裂缝面上的微凸体入手，分析和对比了天然裂缝、人工但未经过处理的裂缝，以及经过粗化处理以后的人工裂缝的静态特征和动态变化，指出了经过粗化处理以后的人工裂缝模拟天然裂缝的依据；②Lade双曲服面屈服准则考虑了所有三个主应力或应力不变量对屈服与破坏的影响，能够较好的反应岩石材料的所有屈服和破坏特性。

Therefore, this process is firstly used to form the chromium carbide layer on the surface of the axle sleeve and bush in the immersed roller used for Strip-Hotgalvanizing unit to improve their working life.
