With the tremendously social and cultural changes in the 20th century , the vacillation of realism ' s connotation and the elastic development of its external form are connected and interact on each other , constituting a peculiar view which we call " the phenomenon of realism " 随着20世纪社会和文化发生巨大变化，现实主义内涵的游移不定与外在形态的弹性发展相互作用并连在一起，构成了“现实主义现象” 。
In contrast , the out - of - phase vacillation in summertime ao covers the arctic region and mid - latitude asian continent . though the summertime ao exists on intraseasonal as well as interannual time scale , its asian active center abates on the intraseasonal pattern , thus awarding it more conspicuous zonal symmetric structure . interannually , summertime ao exhibits the zonal asymmetric and baroclinic features , and its seesaw mode is significant only in the lower troposphere 在年际时间尺度上，夏季北极涛动表现出比冬季北极涛动更强的纬向非对称性和对流层高、低层位相不一致的斜压性，其极地中心和亚洲中心的反位相涛动关系在对流层低层比较显著，向上逐渐减弱，到对流层高层不能表现明显的亚洲中心。
The experiment results show that when other initial parameters are kept constant , the heat and mass transfer of falling film absorption under the condition of normal vacillation of fishing vessels is better than that in static status ; the amplitude and period of vacillation directly influence the performance of the absorber and an adequate decrease of vacillation period or vacillation amplitude is beneficial to the absorption performance 实验结果表明，当其他初始参数一定时，在渔船常见的摇摆振动条件下，降膜吸收器的热、质传递优于静态下的情形；摇摆振动频率和幅度直接影响降膜吸收性能，适当减小摇摆周期或摇摆幅度均有利于提高降膜吸收性能。
