This paper discribes the degradation phenomenon formed in the long-term cyclic charge and discharge of fast ionic conductor Na-β-Al_2O_3. Besides the rapid degradation (mcdel Ⅰ) generally assumed, there exists also a slower degradation (model Ⅱ)which starts at the grain boundaries or the phases between grains of the materials and accompanied by the recombination of electron-ions as well as the decline in electric properties such as electric conductivity etc. untill the failure of its...

This paper discribes the degradation phenomenon formed in the long-term cyclic charge and discharge of fast ionic conductor Na-β-Al_2O_3. Besides the rapid degradation (mcdel Ⅰ) generally assumed, there exists also a slower degradation (model Ⅱ)which starts at the grain boundaries or the phases between grains of the materials and accompanied by the recombination of electron-ions as well as the decline in electric properties such as electric conductivity etc. untill the failure of its mechanical structure.In addition, it points out that calcium ion is a very harmful additive for this sodium--alumina insulater in solid Na/S battery system. The harmful effect not only exists in the material when calcium ions are doped before sintering, but exists when the pure sintered sample is soaked in the molten solution(CaCl_2+NaCl), even the content of CaCl_2 is only 0.1 mol%. The mixed additives are concentrated abundantly around the grain boundary and triple grain junction zones. The activation energy of Nat ions will increase to 0.57 eV when the concentration of Ca~(2+) ions is up to 2.0 mol%, and then it will lead the fast ionic conductor to lose its superionic conductibility.

本文叙述了快离子导体Na-β-Al_2O_3长期往复充放电后形成的衰变现象。除通常认为的快速衰变(Ⅰ型衰变)外,还存在一种缓慢衰变(Ⅱ型衰变)。缓慢衰变开始于材料体内的晶界及粒间相,并伴随着电子-离子的重新组合及电子电导等电性能的老化以至机械结构上的破坏。 文中还指出Ca~(2+)是这种用于固体钠/硫电池系统的Na-β-Al_2O_3隔膜的一种十分有害的附加物。它的有害影响不仅在烧结以前掺入材料时存在,当焙烧过的纯净样品浸渍于熔融的(CaCl_2+NaCl)熔液后亦复存在。后者,甚至当CaCl_2含量为0.1mol%时即很明显。引入的附加物亦常富集于晶粒间界及三晶粒交界区域。当Ca~(2+)的浓度增至2.0mol%时,Na~(2+)的激活能将增加到0.57eV,从而导至快离子导体失去它的超离子电导特性。

In this paper, the dynamic problem of a soil——nonlinear MDF shear structure interaction system is analyzed. A trilinear stiffness degradation model of the material of the super-structure is taken as a restoring force. By separating the nonlinear term in the equation of motion of the system into linear and nonlinear components and then putting the later to the right hand of the equation as an additional load, the nonlinear response of the system can be computed by means of the Modified Method of Fourier...

In this paper, the dynamic problem of a soil——nonlinear MDF shear structure interaction system is analyzed. A trilinear stiffness degradation model of the material of the super-structure is taken as a restoring force. By separating the nonlinear term in the equation of motion of the system into linear and nonlinear components and then putting the later to the right hand of the equation as an additional load, the nonlinear response of the system can be computed by means of the Modified Method of Fourier Transform-Time Domain Iteration (MFTTDI). Finally, a satisfactory convergent result is obtained.

According to a thermal degradation model of the kerogens, this paper gives a series of carves showing the relationship between the rate of oil generation and the depth of burial for the estimation of the total amount of oil generated in a specific area, The curves are constructed from the laboratory thermal degradation data of various source rocks together with reflatory index of vitrinites under various simulated temperature and the relationships between the maximum cumulative rate of oil generation and type exponents of kerogens…etc. With these plots,cumulative rate of generation curves are further determined according to the average type exponents of kerogens in the source rocks ineach formation in the western sag of the Liaohe depression; and the total amount of oil generated from the source rocks in various formations in the whole thermal evolution process by means of these data combined with related geochemical parameters. Principly, the technique as presented in this paper can be used to estimate qnantitatively any source rock body which had undergone various development stages.
