Examples
- Gamma ray source container
射线源容器 - In recent decades , with rapid development in space science and computer technologies , astronomers discovered many new and exotic celestial objects . some celestial objects like supernova 1987a can help to reinforce the theory of stellar evolution . but others such as gamma ray sources pose more headaches and sometimes conflicting theories
近年来，由于太空科技及电脑技术的迅速发展，天文学家发现了很多以往从未见过的新天体，有些天体例如超新星1987a能令恒星理论基础更加巩固，但亦有一些奇异天体例如伽玛射线源却令天文学家感到束手无策。 - The whole - body gamma knife system is a kind of non - invasive medical instrument by using co - 60 as the gamma ray source . according to geometrically focusing theory , the gamma knife system can precisely focus in spirals 30 beams of gamma rays from different directions to a target through a collimator . by the collimator s direction , the predetermined lesion will be under radiation in heavy dose and subsequently be destroyed completely
体部伽玛刀是利用能产生伽玛射线的钴60作为放射源，根据几何聚焦原理，将30束伽玛射线从不同方向和位置通过准直后经一个固定的轴旋转聚焦到焦点，形成品质优良的剂量区，将肿瘤组织置于该高剂量区中，即可在预定时间内将病变组织摧毁，体表和焦点以外的正常组织仅受到瞬时照射而基本上不受损伤。
