根收敛 [
gēn shōu liǎn]
root convergence
- 该方法不但保持了传统的行列式查找法的优点,而且克服了其迭代不收敛、漏根等缺点,并具有较高的速度加速比。
This method not only retains the advantages of the conventional determinant search method, but also overcomes its disadvantages such as leaking roots and nonconvergence, and has a higher speed-up. - 为了考察中国农村发展地区差距的变化趋势,我们采用面板数据单位根检验的不同方法对其收敛性进行了严格的计量检验。
We test the convergence with unit root test of panel data to examine the trend of China rural development regional disparity. - 为克服潮流雅可比矩阵在临界点处的奇异,零特征根法一般需对负荷水平λ作适当变换方可保证算法的收敛性,但这同时又使雅可比矩阵原有的稀疏性遭到不同程度的破坏。
To avoid the singularity of Jaccobian matrix at Point of Collapse, zero eigen value method needs conversion to λ, which destroys the sparsity of Jaccobian matrix.
