放射冠 的英文怎麼說
中文拼音 [fàngshèguān]
放射冠
英文
corona radiate-
The uses of this adaptable material have been broadened dramatically by new technologies : glass fibre optics ? more than eight million miles ? carrying telephone and television signals across nations, glass ceramics serving as the nose cones of missiles and as crowns for teeth ; tiny glass beads taking radiation doses inside the body to specific organs, even a new type of glass fashioned of nuclear waste in order to dispose of that unwanted material
這種適應性強的原料的使用通過新技術顯著地被擴大了:玻璃光學纖維-長於八百萬英里-承載著電話和電視信號越過國家，玻璃陶瓷製品應用於飛船前端椎體和牙冠；帶放射線的小玻璃珠在身體內有特殊的功效，甚至一種新的玻璃類型是核廢料式，為了除去不必要的原料。
