摘要：Ionic liquids combined with supercriticalfluid technology hold great promise as working solvents for developing compact *** liquids,which are organic molten salts,typically have extremely low volatility and high functionality,but possess high viscos-ities,surface tensions and low diffusion coefficients,which can limit their ***_(2),on the other hand,especially in its supercritical state,is a green solvent that can be used advantageously when combined with the ionic liquid to provide viscosity and surface tension reduction and to promote mass *** solubility of CO_(2) in the ionic liquid is key to estimating the important physical properties that include partition coefficients,viscosities,densities,interfacial tensions,thermal conductivities and heat capacities needed in contactor *** this work,we examine a subset of available high pressure pure component ionic liquid PVT data and high pressure CO_(2)-ionic liquid solubility data and report new correlations for CO_(2)-ionic liquid systems with equations of state that have some industrial applications including:(1)general,(2)fuel desulfurization,(3)CO_(2) capture,and(4)chiral *** measurements of solubility data for the CO_(2) and 1-butyl-3-methylimidazolium octyl sulfate,[bmim][OcSO4]system are reported and *** the correlation of the CO_(2) ionic liquid phase behavior,the Peng-Robinson and the Sanchez-Lacombe equations of state were considered and are *** is shown that excellent correlation of CO_(2) solubility can be obtained with either equation and they share some common characteristics regarding inter-action *** the Sanchez-Lacombe equation,parameters that are derived from the supercritical region were found to be important for obtaining good correlation of the CO_(2)-ionic liquid solubility data.

摘要：Public vehicle seats are used under diverse conditions, therefore, the design of these seats is desired to be universal design. In the past study, seat swing function used in public vehicle seats, and it was optimized from the mechanical aspect under diverse conditions. Seat swing function is the function to prevent hip-sliding force, which causes sitting uncomfortable feeling. Recent study clarified that the reduction of blood flow in the legs causes physiological dysfunction, which is one of the causes of Long Flight Thrombosis, and the social issue. Thus, in the design of seat swing function, it is necessary to consider not only mechanical aspects but also physiological aspects. For the universal design of seat swing function considering the physiological aspect （blood flow）, the influence of blood flow on seat swing function in diverse conditions was analyzed. The method of this study was measuring blood flow and body pressure distribution on seat cushion of seat swing function under diverse conditions. From the analysis, it was indicated that it was necessary to reduce the compressive force behind the knees of the user conditions; the short physique and the high weight physique in standard sitting posture, for the universal design of seat swing function to prevent reduction of blood flow in the legs.
