It was found that increasing pressure for blank can improve the compactedness of blanks so as to make foam aluminium materials with homogeneous pores. Foaming temperature, as one of the main influencing factors on foaming process, should be controlled higher than the melting point of Al or Alalloy to a certain extant in order to keep a reasonable viscosity. Thus, the foam aluminum with homogeneous pores and high porosity is available. As shown by experiments, such materials should be made on conditions that they shall be protected with molten salt under 300?MPa pressure at 675～680?℃.

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。
