The 3D reconstruction and concision of body internal organs can be built with such high quality that they are better than those obtained from the traditional methods. With the function of dynamic concision, the VRML browser can offer better windows for man-computer interaction in real-time environment than ever before. 3D reconstruction and dynamic concision with VRML can be used to meet the requirement for the medical observation of 3D reconstruction and have a promising prospect in the fields of medical imaging.展开更多

However, in the truth-conditional enterprise generally, it seems advisable to settle on a single depiction of time. Linear time is the simpler framework, and branching time faces difficulties for which we seem to have no immediate solutions. This paper defends the applicability of linear time. The apparent branching of time results from the use of speech acts other than factual assertion. Truth in correspondence with specific conditions is relevant when making factual assertions. However, we are in no epistemic position to advance factual assertions about the future, but only suppositions and predictions. For these, the truth-conditional content is employed differently. For suppositions and predictions, we only ＂pretend＂ to reference things, to assert facts, and to accept them as ＂true.＂ There is a wide array of alternatives about what we can suppose or predict, giving the impression of branching options. Suppositions and predictions under active consideration are often marked with present tense, whereas those that are inactive （not presently under active consideration but nonetheless relevant） are often marked with past tense.展开更多

Adorno＇s language thought is derived from Benjamin＇s extensive language theory in which Benjamin claims that all things including human being have languages. The telos of art＇s expression is expressing what the repressed things and human long for speaking. The authentic art preserves the trace of primordial human＇s instinct： mimesis. Through the subject miming the object in the expression of art, the real cognition is realized. According to this model, we can ascertain that artist is the real epistemological subject, the ＂collective subject＂ is factually the speaker of the expression and the epistemological objet which is primary in the production of art. Since art is a language, the standard of art is truth-false, and therefore, the truth content is the criterion of authentic art. Negativity is the core character of truth content.展开更多
