auxiliary equation meaning in Chinese
辅助方程
相伴齐次方程
Examples
- A new auxiliary equation and solitary wave solution to nonlinear evolution equations
方程的新的精确孤立波解 - Auxiliary equation method and solitary wave solutions to nonlinear evolution equations
非线性发展方程的孤立波解 - Construction of the exact solitary wave solutionsof the non - linear evolution equations using a new auxiliary equation
新的辅助方程构造非线性发展方程的孤立波解 - Moreover , existence of analytic solutions for a linear iterative equation with variable coefficients is given by reducing to an auxiliary equation and using schauder ' s fixed point theorem
此外， 、本章还使用sehauder不动点定理，通过建立辅助方程，研究了变系数的线性型迭代方程解析解的存在性。 - Instead , there needs to store only the original coefficient matrix , some auxiliary matrices for the preconditioner and several vectors in the iteration methods . further , the core of the iteration is the matrix - vector multiplication and the solution of the auxiliary equations corresponding to the preconditioner . if the solution of the auxiliaries spend not very much , the computational cost in each iteration step will be very cheap , due to the fact that the sparsity of the matrix can be exploited sufficiently
与直接法相比，迭代法只需存储原系数矩阵、对应于预处理的几个辅助矩阵与少量几个向量，且迭代中除求解辅助线性方程组外，其余的计算主要是稀疏矩阵与向量乘积，从而能充分利用稀疏性减少计算量，但迭代法的收敛速度一般与系数矩阵的谱分布有关。
