We observe that in the case of ideal voltage sources, equation required for the node method breaks down . 我们注意到在存在理想电源的情况下,节点分析法的方程就失败了。
As a dom node method 的内容作为dom节点(方法
A novel correlative node method for pattern recognition of retinal blood vessels 一种新颖的视网膜血管形态识别相关网点法
Changing basis function is an effective method . so , fixed nodes method which needs same numbers of points in every sub - domain is advanced 因此,本文首先提出了固定节点法。该方法要求在每个影响域内含有相同的结点数目。
In this paper , a model of debris flow is calculated by using the finite nodes method with triangle cells . the method is combined with fdm and fem . vast applications proved that it can suit for complex boundary as fem and is efficient as fdm 这种方法将有限元的思想与有限差分的方法结合起来,吸收了有限元方法中三角网格模拟边界条件符合实际情况的优点,又具有差分方法计算量小的特点,方法的适用性经过了大量工程实践的检验。
According to the characteristic of the distribution network , based on thenewton - raphson method , used the object - oriented thought , bring forward an unite load node method for power flow calculation , and making a improvement of the node number method which is suitable for newton - raphson method , obtained a rapid convergence calculation method for power flow calculation 根据配电网的特点,基于牛顿?拉夫逊法运用面向对象的思想,提出了负荷节点合并的潮流计算方法,并引入了改进的,适合于牛顿拉夫逊法的节点编号方案,得到了一个快速收敛的潮流算法。
Then an efficient and more accurate nonlinear finite element procedure based on the plastic node method ( pnm ) by combining elastic large displacement analysis theories with a plastic hinge model is presented to analyze the ultimate strength , directly accounting for the geometrical and material non - linearity and the influence of initial deformation and residual stress 然后采用塑性节点法,考虑结构的几何非线性和材料的非线性双重以及各缺陷因素影响,分析了不对称船体结构的极限强度。通过与实验值的比较,说明简化方法与塑性节点法都能较准确预报极限强度。
