机械工程 电磁发射 Moreover, it has been found that the composites have an obvious electromagnetic emission during breakage. This property makes carbon fiber/polymer composites a possible intelligent material, and will enlarge the application field of this kind of materials. 此外,我们还发现该材料在破坏时有明显的电磁发射现象,这使得碳纤维/树脂基复合材料可作为一种智能材料,将进一步拓宽碳纤维/树脂基复合材料的应用领域。

地球科学 电磁辐射 Firstly,the hazard extent of rock burst is analyzed to determine the index of the hazard of rock burst and to present the incipient forecast. Secondly,the rock burst can be forecasted instantaneously with electromagnetic emission (EME) and drillings. 孤岛工作面冲击矿压危险检测预报及控制的技术是先分析冲击危险程度,确定冲击危脸指数,提出早期预报,然后,采用电磁辐射和钻屑法进行及时预报,最后,采用卸压爆破进行处理,并采用电磁辐射和钻屑法检验防治措施的效果。
