Copper nanoparticles were modified by surface modifier, methyl - methylacrylate, and minified by use of fluid-flow comminuted method, the disper sity and dispersion stability of the modified copper nanoparticles as additive i n CD 15W/40 engine oil were evaluated by high velocity centrifuger; its morpholo gy and particle size were tested by TEM and XRD analysis; and its tribological p roperty in CD 15W/40 engine oil was investigated by ball on pan tribo-tester.

采用化学改性法与液流粉碎机械法对纳米铜微粒进行了表面改性和分散研究，采用高速离心机考察了表面改性后纳米铜微粒作为添加剂在CD15W/40柴油机油中的分散性及分散稳定性，采用TEM、XRD测试了表面改性纳米铜微粒的形貌及粒径大小，采用球盘磨损试验机考察了表面改性纳米铜微粒作为CD15W/40全配方调配油添加剂的摩擦学性能，用SEM、EDS观察了磨损表面的形貌、线扫描、面分布及元素含量，分析了纳米铜微粒在摩擦过程中的减摩润滑机理。结果表明：甲基丙烯酸甲酯化学改性结合液流粉碎方法处理后纳米铜微粒的粒径进一步均匀、细化，平均粒径为24nm，并在CD15W/40油中分散性好，悬浮稳定时间长。

That was the first and the only time a CD version by EMIitself, besides these Etudes, some other selections were also the first time on CD. Too bad it was not an international reissue and without wide circulation, they became extremely hard to find since then and were mainly kept within the circle of Japan collectors. People sigh and envy but what really can we do? That's what japanese always like to do with the reissues of historical music material: Charity begins at home.

这是自1928年以来，首次以母公司名义发行的CD版本，除了肖邦练习曲收录在内，并有不少其他录音首次CD化，可惜没有海外发行也没有广泛流传，估计大部分成为了日本本土收藏者的挚爱，外地人只能望洋兴叹，不过这也是日本人对再版历史录音的一贯作风：肥水不流外人田。
