The size of the particles disperses uniform as well as narrow ( obtained by reverse micelle method in the system of aot / iso - octane / water and trion x - 100 / caprylic alcohol / cyclohexane / water ) 通过透射电子显微镜观测到两种体系合成出的粒子粒径在5nm左右，且粒子呈单分散，粒径分布均匀。

We can see from the photos of the sem that the diameters of the powers of this tree land of materials obtained by the system of trion x - 100 / caprylic alcohol / cyclohexane / water are about 20 nm . by means of uv - vis , atomic absorption spectrometry and so on , nanoparticles of this three kind of anode materials are synthesized 利用trionx - 100 /正辛醇/环己烷/水反胶束体系制备出三种物质的粉体，扫描电子显微镜照片显示粒子的粒径在20nm左右，分布均匀；此外还利用uv - vis 、原子吸收光谱等测试手段，都表明合成出了三种正极材料的纳米粒子。
