| 4. | In addition , research on radiation effects of mos capacitor implanted bf2 + at low dose rate are also made in short 此外,本文还开展了bf _ 2 ~ +注入mos电容低剂量率辐照效应的研究工作。 |
| 5. | The radiation effects of mos devices implanted bf2 at low dose rate are investigated in some different respects in this paper 本文从不同方面对bf _ 2 ~ -注入mos管低剂量率辐照效应进行了深入的研究。 |
| 6. | This risk factor table roughly shows the relationship between radiation doses and its effects on human body . it should be note that experimental data for dose - effect relationship are still scanty , especially for low doses and low dose rates 到目前为止,有关辐射效应与剂量的关系的资料还是非常贫乏,尤其缺乏人群在小剂量及低剂量率时的资料。 |
| 7. | 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。 |
| 8. | Firstly , the theories relative to radiation effect are discussed in brief , including some models of interface trap formation and process of producing oxide trap charge in radiated mos devices . besides , the radiation effects at low dose rate and the mechanism of radiation hardening for bf2 implantation are reviewed too 首先,对有关辐照效应的理论进行了简要的叙述,介绍了辐照过程中氧化物陷阱电荷的产生过程以及界面态建立的一些模型,另外,还对低剂量率辐照效应以及bf _ 2 ~ +注入加固mos器件的机理做了回顾。 |
