1·The large system is divided into several subsystems by using diakoptical technique, and related rows of nodal point impedance matrices are solved.
应用分块技术将大系统分割为若干子系统，求出节点阻抗矩阵中相关的列。
2·This full moon eclipse will be given greater strength by falling directly on the solstice, considered a highly important nodal point.
那么满月日蚀要给予更为巨大的力量直接在下降日，被认为是一种非常重要的节点。
3·Based on modes modification method, the acoustic pressure is found and reduced by optimizing the velocity of the nodal point in main vibrant area.
基于模态修改法优化主要振动区域腹部节点的速度来降低车内噪声。
