To improve computing precision, the latter applies interpolating function of curved - quadrilateral element containing six npdes to thicking the influence surface of grillage. compared with lagrangian interpolation for rectangular element and triangle plane interpolation, this way not only improves computing precision but be more suitable for the curved - bar grillage analyzing method introduced this paper
為了提高計算精度，本文應用六結點曲邊四邊形單元插值函數加密梁格影響面，與矩形單元拉格朗日插值及三角平面插值方法相比，不但提高了計算精度，且更適于曲桿梁格分析。
