选区衍射 meaning in English

selected area diffraction
selected diffraction
selected-area diffraction

With the more modern ` four - lens ' microscopes the added flexibility removes this restriction and selected area diffraction is typically available for magnifications within the range 1 0 000 to 500 000 times
更先进的四透镜显微镜增加的适用性消除了这个限制，选区衍射对在10000到500000倍的放大中有代表性作用。
The transmission electron microscopy ( tem ) images show that ceo2 nanowires are about 60 nm in diameter , which correspond to the pore sizes of the membranes used . the selected - area electron diffraction ( saed ) pattern indicates that the nanowires selected are single crystals
从透射电镜(几玛图像可以得知ceo :纳米线直径大约60nln ，与所用膜的孔径相符，电镜选区衍射( saed )显示所选的ceo :纳米线为单晶结构。
Especially , the nano - iron and nano - tungsten sols as well as their powders were characterized in detail by xrd , ft - ir , uv - vis , xfs , tem , sem , edax and so on . another new method is put forward firstly to estimate the addition of dispersants and its effect by uv - vis
