According to testing results, the stress - strain curve of the cemented soil stabilized the nanometer silica fume is fitted using a quadratic parabolic curve and expression equation for upward sector of the stress - stra in curve is given
根據試驗結果，分析了納米硅粉水泥土的變形特性，並對其應力應變曲線進行了二次拋物線擬合分析，推導了曲線上升段的表達式。 -
Firstly, we study the periodic parabolic equations with delays by using the method of upper and lower solutions and its associated monotone iterations, it is shown that the reaction function in the system possesses a quasi - monotone property and the periodic boundary value system has a pair of coupled t - upper and lower solutions then the periodic boundary value problem has a pair of periodic quasi - solutions and the sector between the quasi - solutions is an attractor of the delayed periodic parabolic system
首先，我們研究含時滯的周期拋物型方程組應用上、下解方法及相應的單調迭代方法，證明：如果反應項混擬單調且方程存在周期上、下解，則方程一定存在周期擬解，並且擬解構成的區間是一個吸引子。
