Research On Thermodynamic Properties And Thermodynamic Geometries Of Black P-Branes

This article research the thermodynamic properties and thermodynamic geometry performance of Black p-branes by studying thermodynamic geometry.This article mainly includes three parts.The first part introduces briefly the basic thermodynamic theory of black hole;The second part introduces the theory of thermodynamic geometry,and show the thermodynamic geometry properties of the several typical black holes in detail;The third part first researches the heat properties and electric properties of the Black p-branes,calculate the heat capacity and the capacitance of Black p-branes under some particular circumstances.This part also research the thermodynamic geometry property of Black p-branes,calculate the metric coefficient and Ricci scalar of Black p-branes.The result shows that the curvature scalar of Black p-branes' thermodynamic geometric is zero in two cases.That means the thermodynamics geometry of Black p-branes is flat.Finally discuss the problem about the flatness of the thermodynamic geometry of black hole.
