Wittgenstein thinks that when people in different language-games argue with one other, they insist on adopting a doubtful attitude toward the reasons provided by the other side. His use of the term "language-game" here is a metaphor, and implies'that people in different cultures can scarcely reason with one another. Indeed, according to Wittgenstein's consideration of concepts of logic in On Certainty, language-games are incompatible with one another because their internal logic and reasons are different from each other. However, in his discussion of empiricalpropositions Wittgenstein has also shown us the possibility that the internal reasons of one language-game can transmit beyond its own borders and be valid in another language-game.展开更多

We argue somewhat in favor of such a system from the point of view of its meta theory (it is complete and consistent one), of properties of duality, symmetry etc., as well as of a logic of a possible world.展开更多

However, previous designs were based on one dimension flow to determine the average fluid parameters and geometric parameters of impeller cross-sections, so that it could not describe real physical processes in the internal flow of the tur- bine expander. Therefore, based on the inverse proposition of streamline curvature method in the context of quasi-three-dimensional flows, the all-over-controlled vortex concept was adopted to design the impeller under specified condition. The wrap angle of the impeller blade and the whole flow distribution on the meridian plane were obtained; meanwhile the performance of the designed impeller was analyzed. Thus a new design method is proposed here for the inverse proposition of the helium turbine expander impeller.展开更多
