The stress calculation method and strength condition of PET aerated water bottle were obtained from theory. The strength of PFT aerated water bottle was simulated and calculated ANSYS. The stress graphics of the bottle with different thickness was plotted and their stress property was analyzed. The influence of axial load and grooves on bottle stress was also studied.

In this paper the dynamics characteristics are analyzed theoretically at first. According to the unique configuration and mechanics characteristics, the mechanics model and kinetic differential equation of the half-tracked air-cushion vehicle are established. Algorithm of mechanics and lifting-state parameters are put forward and analyzed. And variation ranges of the driving state parameters are obtained and the corresponding influence factors are analyzed. The further qualitative studies on control model are carried out.

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。
