Second, the barycentric coordinates were separated from the matrixes with proper simplifications. 其次構造併合理簡化影響係數矩陣，將質心坐標從矩陣中分離出來，則構件的運動可以唯一地用其自身的質心坐標表示。
The coordinates of the centre point of a subsidence trough are calculated by the effect transference angle and the mining depth. 利用平面圖形幾何重心公式計算回採工作面水平投影圖形的重心坐標，然後根據影響傳播角和開採深度計算下沉盆地中心位置的坐標。
We apply the method of bargcentric coordinates to give the proof of some geometric inequality conjectures about a motion point that is the triangle in sids. 利用三角形重心坐標證明涉及三角形內部一動點的若干幾何不等式猜想。
