Abstract

The invention discloses a motion conversion experiment device in a thermodynamic system, which mainly comprises a base, a circulation motion device, a plurality of elastic column bodies distributed around the circulation motion device and barriers corresponding to the elastic column bodies, wherein the circulation motion device and the elastic column bodies are all movably connected with the base; the barriers are arranged at the same sides of the elastic column bodies; when the elastic column bodies rotates under the effect of external force, the barriers are used for limiting the elastic column bodies to enable the elastic column bodies to impact the circulation motion device in single direction. An ideal machine is amplified to manufacture a simulation device normally observed by the naked eye, the elastic column bodies rotating around fixed axes impact the circulation motion device in single direction, continuous single-direction rotation can be realized, an amplification model manufactured by converting fluctuation in an air system into directionally-rotating mechanical energy in the way is realized, the process is successfully simulated, and accuracy of microscopic particles from disordered motion to ordered motion.

Description

technical field [0001] The invention belongs to the field of physical experiment devices, in particular to a motion conversion experiment device in a thermodynamic system. Background technique [0002] As early as 1901, Perrin, who confirmed the existence of atoms with Brownian motion experiments, pointed out that Brownian motion is a reversible process, so it will lead to short-term or local entropy reduction, which undoubtedly strongly questions the second law of thermodynamics. But as we all know, the research on this (entropy reduction caused by fluctuations) has disappeared. Because it is generally believed that the second law of thermodynamics is a statistical law that only applies to a large range of situations. Since it is a "statistical law, applicable to a wide range of situations", why not further study the microscopic process? What led to the termination of this process was the appearance and influence of the "Maxiwell Demon". In 1867, Maxwell mentioned in a l...
