impact probe
2.distorted wave Born approximation (DWBA) and so oa On the other hand, cross sections for the removal of atomic inner-shell by electron impact are needed in fields of application including materials analysis by electron-probe microanalysis (EPMA), surface analysis by Auger-electron spectroscopy (AES), and thin film analysis by electron energy-loss spectroscopy (EELS).
3.In order to probe into the factor of influnce on the fatigue crack growth rate of the low-alloy steel A533B and carbon steel STS42 in environment of BWR (Boiling Water Reactor) , a lot of experiments have been carried out. Following conclusions can been made: (1) The change of temperature makes an impact on the fatigue crack growth rate of these two kinds of steel material.
