| 1. | Immediate effects may show up after a single exposure or repeated exposures
立即的效果在暴露或重复的暴露之后可能出现。 |
| 2. | The amount of nickel released from the euro coins was up to 30 times above a level regarded by scientists as the concentration threshold for reactivity to a single exposure
实验结果表明，当人们手拿这种硬币时接触到的镍竟然比科学家实验得出的能够引起过敏反应的最低镍浓度高出30倍。 |
| 3. | We divided the exposure processes between those in which a single exposure can cover the entire circuit and those in which three exposures are needed per layer , developing new manufacturing technologies to help reduce the production processes and cost
我们将那些处于一次曝光和多次曝光之间的曝光过程进行分割，并开发出新的制造技术来减少生产工序和成本。 |
| 4. | The risk factors are deduced from a single exposure of more than 1 gy and are subject to certain uncertainties . the figures are therefore neither precise nor final . they should be used carefully mindful of their limitations
因此危险度分析是推测性的，所根据的数据和资料主要来源于一戈以上单次照射的结果，而且有一定的不确定性，所以在应用时要留意其局限性，不能视其为精确的或不变的数据。 |
| 5. | Mathematical and physical models for multi - beam and multiple - exposure techniques including single exposure with double - beam , double - exposure with double - beam , single exposure with tri - beam , double - exposure with tri - beam , four - beam and five - beam interference are established . simulation software is programmed , large numbers of computer simulation research have been carried out and a lot of useful results have been obtained
建立了多光束、多曝光技术，包括双光束单曝光、双光束双曝光、三光束单曝光、三光束双曝光、四光束和五光束干涉的数学物理模型，编制了模拟软件并进行了大量的计算模拟研究，得到很多有用的结果。 |
| 6. | It should be note that experimental data for dose - effect relationship are still scanty , especially for low doses and low dose rates . the risk factors are deduced from a single exposure of more than 1 gy and are subject to certain uncertainties . the figures are therefore neither precise nor final
因此危险度分析是推测性的，所根据的数据和资料主要来源于一戈以上单次照射的结果，而且有一定的不确定性，所以在应用时要留意其局限性，不能视其为精确的或不变的数据。 |
