为提高工业球磨机的生产能力并降低能耗，提出了使用磨煤机的轴承振动特性来测量球磨机筒内料位的新方法。

Firstly, milling mechanism of planetary ball mill and process of flaking microsphere aluminum powder were introduced simply in milling process,and several main factors were also discussed in course of milling aluminum powder by planetary ball mill.

首先，简单介绍了球磨工艺过程中行星式球磨机的球磨机理及微球铝粉片状化过程，并讨论了用球磨机在球磨铝粉过程中的几个影响因素；其次，是分离工艺过程中筛分和过滤待改进的工艺条件；第三，探讨了捏合过程对整个产品体系稳定性的影响；最后，简易配制涂料，采用相关仪器对产品质量进行评价，并提出三方面的改进要求。

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.

复解析函数则不同：凡复解析函数必为全纯函数（即复可导，以实变量表示则是满足柯西-黎曼方程），反之亦然，因此全纯函数与解析函数在复分析中是同一类对象。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
