在Biot饱和土波动理论的基础上,用单排孔列作为屏障,对全空间饱和土中入射平面快纵波进行了隔离分析。采用波函数展开法,将入射波和散射波的势函数展开成Fourier-Bessel函数的无穷级数的形式,利用一组可以求解多散射问题的圆柱坐标系统和界面处位移连续的条件,得到问题的理论解。对影响隔离效果的孔间距和饱和土的渗透性等参数进行了分析,结果表明,单相弹性土体中孔列隔离效果要比饱和土体差,饱和土的渗透性对隔离效果有较明显的影响,饱和土渗透系数越小,孔列屏障后一定距离处的隔离效果越好。

Na-ion cathode materials with a fast charge and discharge behavior are needed to develop future high energy sodium-ion batteries(SIBs).However,inevitably complicated phase transitions and sluggish kinet ics during insertion and removal of Na+in P_(2)-type layered transition metal oxides generate structura instability and severe capacity *** get rid of such a dilemma,we report a structural optimization strategy to promote P2-type layered transition metal oxides with more(010)active planes as an efficien cathode for *** a result,as-prepared hexagonal-prism P2-type layered Na_(0.71)Ni_(0.16)li_(0.09)Co_(0.16)Mn0.6O_(2)cathode with more(010)active planes delivers a reversible capacity of 120.1 mAh/g at 0.1 C,impressive rate capability of 52.7 m Ah/g at 10 C,and long-term cycling stability(capacity retention of 95.6%ove200 cycles).The outstanding electrochemical performance benefited from the unique hexagonal-prism with more(010)active facets,which can effectively shorten the diffusion distances of Na+,increase the Na-ion migration dynamics and nanostructural stability during cycling verified by morphology character ization,Rietveld refinement,GITT,density functional theory calculations and operando XRD.
