微正则系统、正则系统和巨正则系统是完全开放系统的特例。在非广延和不完全统计的框架内,基于不完全Shannon熵,利用最大熵原理,导出了完全开放系统的统计分布.我们使用这个分布计算线性细丝的物理性质。结果与不完全E-V分布的计算结果相同,只是用热力学变量的平均值代替了相应的常数。然而,热力学变量的相对涨落是完全不同的。在正则和巨正则分布中,相对涨落与。在完全开放系统的不完全统计分布中,相对涨落与1成正比。这一结果可以解释一些传统和现代统计力学无法解释的现象,如临界态、过冷态和过热态的大涨落。
Micro canonical, canonical and grand canonical systems are special cases of completely open systems. Within the framework of non-extensive and incomplete statistics, we derive the statistical distribution for a completely open system on the basis of incomplete Shannon entropy, using the maximum entropy principle. We calculate the physical properties of a linear filament using this distribution. The results are the same as those calculated using the incomplete E-V distribution, except that average values of the thermodynamic variables replace the corresponding constant values. However, the relative fluctuations in thermodynamic variables are completely different. In the canonical and grand canonical distributions, relative fluctuations are proportional to . In the incomplete statistical distribution for a completely open system, the relative fluctuations are proportional to 1. This result can explain some phenomenon that traditional and current statistical mechanics cannot explain, such as the large fluctuations of critical, super-cooled and overheated states.
