本文采用近似的激波关系、球锥体压力分布、平衡气体状态方程、边界层厚度计算公式及转捩准则等,按照流管法计算了4种再入飞行器的外流转捩雷诺数和转捩距离,并给出了高硅氧、碳石英、碳碳球锥模型的转捩雷诺数范围,对再入飞行器和模型的计算结果作了分析和比较。

A detailed study has revealed that the ore bodies in the Xitieshan Pb-Zn Mine are mostly trapped within the intra-bed open space caused by folding between the thick-layerd marble and the carboniferous quartz shist along the hinge zone of the main-phase fold, and its vicinity. Furthermore, it is found that the post-folding ductile shear zone is strainly partitioned with structural transposition, and that the transposition pattern is the major factor to control the sizes and shapes of the ore bodies found along...

A detailed study has revealed that the ore bodies in the Xitieshan Pb-Zn Mine are mostly trapped within the intra-bed open space caused by folding between the thick-layerd marble and the carboniferous quartz shist along the hinge zone of the main-phase fold, and its vicinity. Furthermore, it is found that the post-folding ductile shear zone is strainly partitioned with structural transposition, and that the transposition pattern is the major factor to control the sizes and shapes of the ore bodies found along zone-Ⅰ, zone-Ⅱ, zone-Ⅲ. It is thus concluded that the final sizes and shapes of the ore bodies in the mining area are not only controlled by the geometric pattern and its spacial orientation of the main-phase fold, but also by the superimposed post-folding ductile shear zone-the way and to what extent it has reworked.

锡矿山铅锌矿受含矿岩系主褶皱和韧性剪切带的双重控制。矿体主要形成于主褶皱转折端厚层大理岩与含碳石英片岩间的构造虚脱及转折端附近。后期韧性剪切带内强弱不同的构造置换型式,是导致Ⅰ、Ⅱ、Ⅲ矿带矿体规模和形态差异的主要因素。因此,矿体最终规模和形态,不但取决于主褶皱的几何形态和空间展布形式,也取决于韧性切剪带对其叠加和改造的程度。

The addition of Si 3N 4 particles to carbon fiber reinforced silica composite increases the mechanical properties, but decreases the thermal properties of the composite because of the precipitation of tridymite. The addition of Si 3N 4 reduces the oxidation of carbon fibers and increases the burning erosion resistance. Result of simulation carried out on the ground shows that such composite can meet the requirements for application to some spaceflight parts.

在碳—石英复合材料中加入氮化硅颗粒可提高其力学性能,但少量鳞石英的析出使材料的热学性能恶化。同时,由于氮化硅减缓了碳纤维的氧化,可以提高材料的抗烧蚀性能。地面模拟实验表明,加入氮化硅颗粒的碳—石英复合材料完全符合某些航天器件的使用要求。
