Reactive materials
原声例句
TED演讲（视频版） 2020年10月合集 And here in Switzerland, we have found that clays produce very reactive materials when they're calcined,that's to say heated to around 800 degrees Celsius, significantly lower than the 1,450 needed to produce cement. 在瑞士，我们发现粘土在煅烧时会产生非常活泼的物质， 也就是说， 加热到 800 摄氏度左右，远低于生产水泥所需的 1, 450 摄氏度。
英语百科
Reactive materialIn the U.S. military, reactive materials (RM) are a new class of materials currently being investigated by the Office of Naval Research and others as a means to increase the lethality of direct-hit or fragmentation warheads. Reactive materials are similar to insensitive high explosives, but are usually thermite-like pyrotechnic compositions of two or more nonexplosive solid materials, which stay inert and do not react with each other until subjected to a sufficiently strong mechanical, electrical or laser stimulus, after which they undergo fast burning or explosion with release of high amount of chemical energy in addition to their kinetic energy. Fragments or projectiles made of such materials have therefore greater damaging effect than inert ones, with expected lethality increase up to 500%. |
