conserved什么中文中文意思

英语翻译
In a closed economic system,money is conserved.Thus,by analogy with energy,the equilibrium
probability distribution of money must follow the exponential Boltzmann-Gibbs law characterized by
an effective temperature equal to the average amount of money per economic agent.We demonstrate
how the Boltzmann-Gibbs distribution emerges in computer simulations of economic models.Then
we consider a thermal machine,in which the difference of temperatures allows one to extract a
monetary profit.We also discuss the role of debt,and models with broken time-reversal symmetry
for which the Boltzmann-Gibbs law does not hold.The instantaneous distribution of money among
the agents of a system should not be confused with the distribution of wealth.The latter also
includes material wealth,which is not conserved,and thus may have a different (e.g.power-law)
distribution.
