• Based on the ncep / ncar reanalysis products , the sea ice concentration data and the observation rainfall data in china , the seasonal , intraseasonal and interannual variations of the atmospheric circulation in the southern hemisphere ( sh ) are systematically analyzed together with their influences on east asian summer monsoon ( easm ) . the major conclusions are summarized as follows : ( 1 ) in the lower level of the troposphere , the semi - annual oscillation ( sao ) is most active along 40 s and 65 s in the extratropics of the sh . over these latitudes , the variance percentages of sao exceed 70 % , and the anti - phase variation of the sea level pressure ( slp ) between the two latitudes is primarily caused by their sao components
  利用ncep ncar再分析资料、南半球海冰密度资料及中国台站降水资料，本文系统分析了南半球大气环流的季节、季节内和年际变化特征及其对东亚夏季风的影响，主要结论归纳如下： ( 1 )对南半球热带外大气环流而言， 40 s和65 s是低层大气准半年振荡最为显著的两个纬带，在这两个纬带上，半年波的贡献都超过了70 ，二者季节变化的反位相主要体现为半年波分量的反位相。
• The character of surface radiation and energy expended over soil temperature variation is that the temperature variation at surface , 5cm depth and 10cm depth are approximately sine curve on clear and cloudy day while this way the temperature variation at 20cm depth shows small extent anti - phase variation and the temperature under 50cm is no diurnal . in contrast , the temperature at 5m , 10cm and 20cm shows linear decrease and the soil - surface temperature is concaved on rainy day
  地表辐射和能量耗散反映在土壤温度变化上的特征是晴天和阴天地表、 5cm 、 10cm的温度变化表现为准正玄曲线， 20cm深处的温度变化呈现出幅度很小的反位向变化， 50cm以下地温已不存在日变化特征；雨天5cm 、 10cm和20cm的温度呈线性递减，地表温度表现出由降雨引起的凹陷现象。
• Abstract : by employing the concept of photon flux , the evolution of the phase and photon flux in the eigenmode state in three - wave mixing , and the requirements for the initial phase and photon flux in this state , are studied in the paper . a special state in which there are only exchanges of the photon flux but no phase variations in the three - wave mixing process is investigated . an all - optical switch based on the eigenmode pushpull nonlinear - optical - mirror is presented , and the properties of this all - optical switch are numerically calculated . the numerical results show that the performance stability is extremely good , and the intensity and phase of the output signal beams can be easily realized and controlled
