Then the reciprocal of temperature is expanding concomitant variable, and the reciprocal temperature and the differential of momentum carry on contraction. We concluded that covariance scalar equation of thermodynamics law covariant of closed system in P-E theory frame, in essence, it is energy conservation equation.

接下来把温度倒数扩展为协变量，并把倒温度与动量微分进行组合，得到在P-E温缩理论框架下的封闭系统热力学定律协变式的标量方程，本质上的能量守恒方程。
