1. The influence of the pitch additive on the infusibility and carbonization is investigated in this paper. The results show that the pitch crack and the reaction between pitch and oxygen are enhanced. 研究了添加对甲苯磺酸对沥青不熔化处理的影响,试验发现对甲苯磺酸的加入促进了沥青的分解以及沥青与氧的结合,加速了沥青不熔化的过程。
2. These metrics include plus and minus load factor time and rates, pitch rates during maximum pitch up and pitch down maneuvers. 这些尺度包括加载/卸载时间、最大正/负过载变化率、最大上仰/下俯机动范围内的俯仰角速率。
3. A pitch mesophase can be prepared from petroleum pitch and coal tar pitch. 从石油沥青和煤沥青中制取沥青中间相物质。
4. A pitch mesophase can be prepared from petroleum pitch and coal tar pitch. 从石油沥青和煤沥青中制取沥青中间相物质。
5. A pitch mesophase can be prepared from petroleum pitch and coal tar pitch. A new-type carbon material with self-sintering function has been made from the mesophase. 从石油沥青和煤沥青中制取沥青中间相物质。可从这种原料中制备出具有自烧结功能的新型碳素材料。
