ODE对periodically的解释是:: y$ H2 J! e: I2 U$ f: x/ Y

但是,ODE在上述解释下面列出了: / x Y2 J: |! b7 r1.1 At regularly occurring intervals. 0 t; @+ i# [( f0 A4 z2 }; i! D所以,感觉这种排版逻辑是有问题的。 9 ~' q! \ ?! F1 l3 I 6 h5 d$ S7 X) W9 u/ S而COD的解释简捷而准确: 4 _0 j/ a( t. Kappearing or occurring at intervals. ; ]" O% M7 B" I" lMWCD解释详尽而权威:0 i' Y. s& F- p& h" v1 H5 x
