radioactive tracer technique |
放射性指示剂技术 |
|
radioactive waste (Any waste that emit radiation in excess of normal background level, including the toxic by-products of the nuclear energy industry) |
放射性废料 |
|
radioactive waste management (The total supervision of the production, handling, processing, storage and transport of materials that contain radioactive nuclides and for which use, reuse or recovery are impractical) |

|
radioactive-convective model |
辐射一对流模式 |
|
radioactivity (The property possessed by some atomic nuclei of disintegrating spontaneously, with loss of energy through emission of a charged particle and/or gamma radiation) |
放射性 |
|
radioelement (An element that is naturally radioactive) |
放射性元素 |
|
radionuclide (A nuclide that exhibits radioactivity) |
放射性核 |
|
radon (A radioactive gaseous element emitted naturally from rocks and minerals where radioactive elements are present. It is released in non-coal mines, e.g. tin, iron, fluorspar, uranium. Radon is an alpha particle emitter as are its decay products and has been indicted as a cause of excessive occurrence of lung cancer in uranium miners. Concern has been expressed at radon levels in some housing usually adjacent to granite rocks or old tin mining regions) |
氡 |
|
rag (Discarded textile waste, either post-consumer waste or pre-consumer waste, such as manufacturing process scraps) |
破布 |
|
rail traffic (The movement and circulation of vehicles transporting goods and people on railroad systems) |
铁路交通 |
|
rail transport (Transportation of goods and persons by railway) |
铁路运输 |
|
railroad vehicle |

|
railway (A permanent track composed of a line of parallel metal rails fixed to sleepers, for transport of passengers and goods in trains) |
铁路 |
|
railway network (The whole system of railway distribution in a country) |
铁路网络 |
|
railway station (A place along a route or line at which a train stops to pick up or let off passengers or goods, especially with ancillary buildings and services) |
火车站 |
|
rain (Precipitation in the form of liquid water drops with diameters greater than 0.5 millimeter) |
