所谓熵,是一个热力学的概念,熵的计算公式为 S=kinω其中ω为热力学几率,k为波兹曼常数。热力学理论告诉我们,孤立系统在平衡状态时,粒子总在匣内呈均匀、对称的平衡分布,具有最大的热力学几率与熵,处于非平衡状态下的孤立系统,则具有较小的热力学几率与熵,它一定要自发地朝增大熵的方向发展,直到具有最大熵的平衡态,由于孤立系统达到平衡态时最无序、最混乱,熵也最大,因而,熵的大小可以作为系统混乱程度的量度。一些倡仪建立“思维信息论”的同志,借用热力学中熵的概念,认为从信息结构的角度来看,信息内容与信息量均足够、相关事物不确定性已完全消除的信
The so-called entropy is a thermodynamic concept. The entropy calculation formula is S=kinω where ω is the thermodynamic probability and k is the Boltzmann constant. Thermodynamic theory tells us that when an isolated system is in equilibrium, the particles always have a uniform and symmetrical equilibrium distribution in the crucible, with the greatest thermodynamic probabilities and entropy, and isolated systems in a non-equilibrium state have smaller thermodynamic probabilities. Entropy, it must develop spontaneously in the direction of increasing entropy until the equilibrium with maximum entropy. Since the isolated system reaches equilibrium, it is the most disordered and chaotic, and the entropy is the largest. Therefore, the size of entropy can be used as a system chaos. A measure of degree. Some comrades that advocate the establishment of “thinking information theory” adopt the concept of entropy in thermodynamics and believe that from the perspective of information structure, information content and information volume are enough, and the uncertainty of related matters has been completely eliminated.
