Global surveyor has far surpassed its design lifetime but scientists still had plenty more targets for the probes camera and science instruments 全球已远远超过其设计寿命测量,但仍有不少科学家更探头指标的照相机和科学仪器
Bfs sensitively probes inter - electron correlation , relativistic and quantum electrodynamics corrections , so it can be used to test the basic many - body atomic theory or interpret spectra from space . the main contents of this dissertation are as follows : 1 the history and development of beam - foil spectroscopy are reviewed , and the characteristics of bfs are also described . the main applications in the spectroscopic studies and lifetime measurement of highly ionized ions are summarized 本文对高离化态cu和ge离子的光谱进行实验研究,得到了一些新的实验结果,论文的主要内容如下: 1回顾了束箔光谱法的发展历史,介绍了束箔光谱法的优点;总结了束箔光谱法在高离化态原子能级研究,高离化态原子能级寿命测量等方面的主要用途。
Radiation effects have been investigated up to - 30 dpa by the heavy ion irradiation simulation and positron annihilation lifetime techniques in the home - made modified 316l stainless steel and the commercially available stainless steel and tungsten , which are used as the beam window materials for the spallation neutron source in accelerator driven radioactive clean nuclear power system ( ads ) . their radiation resistance properties are compared 本工作采用重离子辐照模拟和正电子湮没寿命测量技术研究了加速器驱动洁净能源系统( ads )散裂中子源束窗材料钨、普通不锈钢和国产改进型316l奥氏体不锈钢在0 30dpa辐照剂量范围的辐照效应,并对它们的抗辐照性能作了比较。
