Energy Science &Engineering, EarlyView.This paper presents a hydrate pressure core processing device integrated with a high‐precision active control system to perform nondestructive transfer, cutting, and analysis. To address the limitations of slow dynamic response and high thermal inertia in traditional passive systems, a differentiated control scheme is implemented.

Mollier-I, S-Diagrams for Combustion Gases in Data Processing [PDF]
In order to have all the thermal and caloric states of combustion gases accessible in a computer, closed mathematical approximation equations were established for the real factors, the enthalpy and the entropy of a real combustion gas.

The enthalpies of combustion and formation of 2,2'-dichloroethyl sulfide
Journal of Research of the National Bureau of Standards Section A: Physics and Chemistry, 1975 The enthalpies of combustion and formation of 2,2'-dichlorethyl sulfìde (mustard gas) have been determined by combustion in an adiabatic rotating-bomb calorimeter. The bomb process has been corrected to: C 4 H 8 Cl 2 S ( liq ) + 7 O 2 ( g ) + 98 H 2 O ( liq ) → 4 CO 2 ( g ) + [ 2 HCl + H 2 SO 4 + 100 H 2 O ] ( liq ) for which the following values
