任一連續曲線可以借一系列很小的拋物線線段較精密地近似表示。 -
This extraordinarily large forecast suggests, however, that we must be more careful in forecasting with a parabolic curve than we are when using a linear trend.
然而，這個龐大的預測數字說明，使用拋物線做出預測比使用直線趨勢做出預測必須更加慎重。 -
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。 -
Based on the theory of thin - walled curved bar, reasonable hypothesized a third - ord parabolic curve, the paper adoptes variational method on energy, taking the coupled relationship of the effect of curvature radius, bend, torsion and shear - lag into consideration, establishes the elastic governing differential equation and boundary conditions for thin - walled curved box girders, which set the foundation of theoretical analysis of shear - lag effect in thin - walled curved box girders
摘要文章以薄壁曲桿理論為基礎，合理地假設了三個剪力滯翹曲位移函數，應用能量變分法推導出考慮曲率半徑影響、彎、扭、剪力滯耦合的曲線箱梁彈性控制微分方程及其邊界條件，為薄壁大麴率箱梁剪滯效應建立了理論分析基礎。
