| 7 | Oxygen-contact charge transfer complexes in organic bicomponent systems显示文摘The O-2-CCT absorption spectra of bicomponent systems were measured. The influences of various organic compounds as well as the component concentration on the O-2-CCT formation ability were investigated. The results show that if the difference of O-2-CCT formation ability between the two components is rather large, such as the benzene/isopropyl ether system, only the O-2-CCT absorption of benzene appears, which arises from its higher O-2-CCT formation ability. If the difference of O-2-CCT formation ability is small, such as the isopropyl ether/ethanol system and the dioxane/isopropyl ether system, it is rather easy to form a dynamic equilibrium of two O-2-CCT between the two components, then only one absorption peak appears in the whole concentration range as a result of the repeated addition of the two kinds of O-2-CCT absorption. If the difference of O-2-CCT formation ability is in medium compared with the two cases above, such as the dioxane/ethanol system, there are two kinds of O-2-CCT absorption of dioxane and ethanol in the same system in the form of an equilibrium, then two absorption peaks can be detected in the middle concentration range as a result of the repeated addition of the two kinds of O-2-CCT absorption. | Junmin Zhu Zhengping Liu Weixiao Cao Xinde Feng | 1998 | Chinese Science Bulletin1998，43，21： | 0 |

| 9 | Irradiation damage simulation of Zircaloy-4 using argon ions bombardment显示文摘To simulate irradiation damage,argon ion was implanted in the Zircaloy-4 with the fluence ranging from 1×10^(16) to 1×10^(17) cm^(-2),using accelerating implanter at an extraction voltage of 190 kV and liquid nitrogen temperature.Then the infuence of ar- gon ion implantation on the aqueous corrosion behavior of Zircaloy-4 was studied.The valence states of elements in the surface layer of the samples were analyzed using X-ray photoelectron spectroscopy(XPS).Transmission electron microscopy(TEM)was used to examine the microstructure of the argon-implanted samples.The potentiodynamic polarization technique was employed to evaluate the aqueous corrosion resistance of implanted Zircaloy-4 in 1 mol/L H_2SO_4 solution.It is found that there appear bubbles on the sur- face of the samples when the argon fluence is 1×10^(16) cm^(-2).The microstructure of argon-implanted samples changes from amor- phous to partial amorphous,then to polycrystalline,and again to amorphous.The corrosion resistance of implanted samples linearly declines with the increase of fuence approximately,which is attributed to the linear increase of the irradiation damage. | Dequan Peng Xinde Bai Feng Pan | 2008 | Journal of University of Science and Technology Beijing2008，15，3： | 0 |
