The dissolubility of PPLA in water was (2.16～4.32)×10－2 mg·mL－1 according to eye judgment. The critical micelle concentration was 2.16×10－2 mg·mL－1 obtained from a fluorospectrophotometer. The self-assembled aggregates of PPLA in water were nanoscale spheres observed by a transmission electron microscope. The particle size and zeta potential tests by dynamic light scattering revealed that during preparation, the ratio of hydrophilicity/hydrophobicity, the aqueous medium and the pH had great influences; while dilution, freezing and pH change to basic condition had no effect after preparation, but pH change to acidic condition made the nanoparticles precipitate.

目测法得到其溶解度为(2.16～4.32)×10－2 mg·mL－1；荧光法得到聚合物的临界胶束浓度为1.12×10－3 mg·mL－1；透射电子显微镜观察显示该聚合物在水中的自组装聚集体为纳米级球形；动态激光光散射测试微球的粒径和Zeta电位发现，在微球的制备过程中，聚合物的亲/疏水性比例、水相介质及水溶液的pH值对它影响显著；而制备后，稀释和冷冻对它无显著影响，改变微球的环境pH值至酸性，出现聚集，至碱性无影响。

Firstly, the mechanism of the preparation of superfine quartz powder with ball mill is studied in this article, based on nature of quartz material, Griffiths strength theory and the crush theory of planetary ball mill.

Some relative characters of reverse micro emulsions of reacting substance/AOT/iso-octane were studied. The phase graphs of the reverse micro emulsions at different temperatures were drawn. And the charts of relationship between conductivity of the reverse micro emulsions and the solubility of H2O or the solution of RDX in them were also done. On the base of them as well as characters and rules of preparation of nanometer materials by the method of micro emulsions, the best conditions were found in the preparation of the reverse micro emulsions.
