乾燥劑除濕器 - 通過蒸汽壓力相差帶來轉移空氣和乾燥劑之間的水分，當乾燥劑又乾又冷，其表面水蒸汽壓力低過空氣中水蒸汽壓力，水分會從空氣中轉移到乾燥劑。當乾燥劑又熱又濕，其中水分因相對較高的水蒸汽壓力而被散發出去，這樣，僅通過調節乾燥劑溫度就可控制乾燥器運作。此文刊登於"煤气与熱力, 1999年 第1期".
A Report on Computation of Skin Burns - Duhamel's Integral method is used to calculate the surface heat flux and the temperature distribution within the skin simulant (the sensor) from the measured surface temperature. On the basis of the calculated surface heat flux, the multilayer model of either opaque or diathermanous skin is solved for the skin temperatures using the Crank-Nicolson Implicit method. From the skin temperature distribution, the degree of thermal injury and the depth of damage for each location of the human body are determined by the burn criteria from the literature. The program also predicts the cumulative area burn with respect to time.
Thermal Injury - To understand the problem of thermal injury and to provide adequate information for assessment of skin damage due to thermal exposure through the use of an instrumented mannikin, the present report reviews the literature of thermal injury. The pioneering works of many investigators (around 1950 to 1970) will be presented. A mathematical and physical analysis of the physiological response of skin to burns will be covered.
