Control effect of pressure-unloaded speed on gas expansion energy released by tectonic coal during coal and gas outburst [PDF]
Meitan xuebaoThe majority of coal and gas outbursts (referred to as outbursts for brevity) occurred in tectonic coal seams. Gas expansion energy stands out as a critical factor contributing to these outbursts.

Geometric expansion of the boundary free energy of a dilute gas [PDF]
Communications in Mathematical Physics, 1987 Extension of previous results by \textit{S. Pogosyan} [ibid. 95, 227-245 (1984; Zbl 0579.60096)] and simplification of the relevant proofs, concerning the geometric expansion of the boundary free energy of a dilute gas, are presented in the paper. Various lemmas, theorems and corollaries are proved.

Generalized Chaplygin gas, accelerated expansion, and dark-energy-matter unification [PDF]
Physical Review D, 2002 We consider the scenario emerging from the dynamics of a generalized $d$-brane in a $(d+1, 1)$ spacetime. The equation of state describing this system is given in terms of the energy density, $ρ$, and pressure, $p$, by the relationship $p = - A/ρ^α$, where $A$ is a positive constant and $0 < α\le 1$. We discuss the conditions under which homogeneity

Co‐planning of electricity and gas networks considering risk level assessment
IET Generation, Transmission & Distribution, 2020 This study provides a risk‐based gas and electricity expansion planning model to coordinate the expansion of electricity and gas networks in a multi‐carrier energy network. Generally, electricity and gas networks have separate owners having no mechanisms
