Structure of basic period of one - dimensional photonic crystal and the characters of forbidden bands 一维光子晶体的基本周期结构及其禁带特征
Last , we have a elementary research on the foundational period of nonlinear autonomous systems 最后,对非线性自治系统的基本周期特性进行了初步探讨。
The superlattice periodicity occurs along the diamond [ 001 ] direction and corresponds to the quintupling of the primary ( 002 ) periodicity 超点阵周期沿金刚石结构的[ 001 ]方向,相当于( 002 )基本周期长度的五倍。
Comparing with small tank , the sloshing in large tank includes not only fundamental mode but also higher modes and its fundamental period is much larger than that of small tank 从与小体积罐的比较可以看出,大型储液罐的液面晃动不只是以基本振型为主,前几阶振型对液面晃动的贡献也比较显著,并且液面晃动的基本周期比小体积罐的大很多。
