塔里木盆地沙尘气溶胶对短波辐射的影响——以塔中为例

, 2008
利用2006年8—9月塔克拉玛干沙漠腹地塔中气象站的80 m铁塔上,距地1.5 m的KIPP&ZONEN自动辐射仪获取的监测资料,根据沙尘暴资料中PM10的小时浓度变化,参照TSP的变化趋势和塔中地面气象站的能见度和风速,将天气划分为晴空、浮尘和扬沙、沙尘暴三种类型,并分别选取其代表性天气,分析以塔中为代表的沙漠腹地,沙尘气溶胶浓度的变化对短波辐射的影响。结果表明:沙尘气溶胶减弱到达地面的总的太阳辐射,在大气总的透过率上表现为晴空是沙尘暴的2.04倍;直接辐射表现在大气透明系数的变化与沙尘暴 ...

低温生长砷化镓光电导天线产生太赫兹波的辐射特性

, 2008
研究了低温生长砷化镓光电导天线(LT-GaAs PCA)产生太赫兹(THz)波的辐射特性。利用太赫兹时域光谱(TDS)技术测量了光电导发射极在飞秒激光作用下辐射的太赫兹脉冲,得到了时域发射光谱,并通过快速傅里叶变换(FFT)得到相应的频域光谱。结果表明,低温砷化镓光电导天线产生的太赫兹波信号比飞秒激光激发半导体表面产生的太赫兹波信号具有更高的强度和信噪比;太赫兹波信号与光电导天线的偏置电压成线性关系;随着抽运激光功率的增强 ...
