  • The vacuum is fast emerging as the central structure of modern physics. This collection brings together philosophically-minded specialists who engage these issues in the context of classical gravity, quantum electrodynamics, and the grand unification program. The vacuum emerges as the synthesis of concepts of space, time, and matter; in the context of relativity and the quantum this new synthesis represents a structure of the most intricate and novel complexity.

  • This paper presents the result of research on equipment development of vacuum injection molding technique for preparation the chopped bamboo fiber polymer composite and some properties of obtained composite material. For the vacuum injection molding technique, firstly the dry fibers were plated in the mold. Then the mold was closed by the vacuum bag, the air inside the mold was sucked out by a vacuum pump, due to the difference of the pressure in side and outside the mold, the polymer liquid was transferred to the closed mold and impregnated the bamboo fiber.

  • The duty and performance of the vacuum mixing and reacting technology for the preparation of lead/acid battery paste is reported. The production results achieved under vacuum are compared with those of conventional, air-cooled plants. Due to the more effective cooling and the use of a closed system, improvements such as reduced burned-lead portion, control of paste composition and formulation accuracy, and independence of climatic conditions are achieved.
