According to eigenvalue equation ( general formula ) of the energy method of the plane steel frame structure stability, and considering the restriction of the end of the column of the main steel frame and function of deflection curve gained from the differential balance equation general resolution, we get the equation for calculating the length coefficient of the main frame structure stability of the steel arch gate and the resolutions are also given
根據平面剛架穩定性能量法特徵值方程（通式） ，考慮弧形鋼閘門主框架柱的柱端約束的特殊情況，求出撓曲線函數（試解函數）通解，得到弧形鋼閘門主框架柱穩定性計算長度系數方程。其中弧門主框架主橫梁式形框架的臨界荷載比較現行規范推薦的有限元法簡單方便、結果精確及物理概念明確等優點。 -
In this paper, we aim at establish heat and mass coupled transfer model in the building wall, the emphasis of this study lies in creating a coupled and non - linear diferential equation system for the heat air and moisture transfer in the wall, which can be described by means of continuum mechanics and irreversible thermodynamics, the most dominant factor is moisture conten 9la gas pressure pc and temperature t, for the description of heatair and moisture transport, the general mass balance equation can be expressed by the temporal change of moisture conten 9 l, gas pressure pc and temperature t that means, in order to create a closed solvable equation system, the other additional dependencies have to be found, which the other variable depending on the variables of the solution : moisture conten 6 l gas pressure pc and temperature to the model is verified by the numerical simulation software which has been developed about building wall.,
