The morphologies of the samples were detected by the scanning electron microscope ( sem ) , showing that the zno micro rods are about thirty microns long with a diameter of 5 ( m 我们还通过简单的热氧化锌粒的方法制备出了zno微柱,微柱的平均直径为2 - 5 m ,长约30 m 。
The sample ' s density , hardness , toughness , x - ray diffraction ( xrd ) , scanning electron microscope ( sem ) and transmission electron microscope ( tem ) analysis have been tested 对所制备的试样进行了密度、硬度、断裂韧性、 x射线衍射分析( xrd ) 、扫描电镜( sem )和透射电镜( tem )的测试。
Calculated the open pore rate , porosity and average leaching time . photomicrograph of representative porous microstructure of matrix were taken by scanning electron microscope ( sem ) 计算平均开孔率、空隙率、氯化钠沥清时间,并进行支架表面与内部孔径和空隙开放情况的扫描电镜观察。
Seed macromorphology and seed - coat micromorphology of 11 species of kadsura ( schisandraceae ) represented by 36 samples were observed under light microscope ( lm ) and scanning electron microscope ( sem ) 在光学显微镜和扫描电镜下对南五味子属11种植物36个样品的种子宏观形态及种皮微形态特征进行了研究。
The surface structures of the pink freshwater pearls from jiangsu - zhejiang region and the white seawater pearls from guangdong province are studied by using polarizing microscope and scanning electron microscope ( sem ) 以产于江浙地区的粉色淡水珍珠和产于广东省的白色海水珍珠为研究对象,采用偏光显微镜和扫描电镜测试方法对其表面结构进行了观察。
