隔震结构正是一种能满足上述要求的新型结构体系，它通过设置隔震层，将结构分为上部结构、隔震层和下部结构三部分，地震能量经由下部结构传到隔震层，由隔震层的隔震装置吸收并消耗主要能量后，仅有少部分能量传到上部结构。

All the atomic shells for the examined atoms are shown and the """"""""reasonable"""""""" electron numbers are given. Especially for atomic subshell and shell structure of transition elements are correctly predicated. This theory provides uniform and objective criterion for shell structure of isolated atom, and the intrinsic and theoretical basis for the shell structure given by other methods. This theory provides a kind of new method for describing the atomic shell structure.
