1) near source problem
近场问题
2) approximation problem
逼近问题
1.
Based on the properties of bisymmetric matrices,a class of constrained inverse eigenproblem and associated approximation problem for bisymmetric matrices were essentially decomposed into the same kind of subproblems for real symmetric matrices with smaller dimensions,and the solutions of the two problems were obtained by applying the conclusions of real symmetric matrices.
根据双对称矩阵的性质,将双对称矩阵的一类约束逆特征值问题及其逼近问题分解成具有较小阶数的实对称矩阵的同类子问题,然后利用实对称矩阵的结果导出双对称矩阵的这两个问题的解。
3) the near-far problem
"远-近"问题
1.
In an asynchronous direct-sequence code-division multiple access (DS-CDMA) communications system, the parameter estimation may be complicated under the near-far problem.
在异步ＤＳ＿ＣＤＭＡ系统中，由于“远－近”问题的影响，给系统参数（传播时延、幅度变化、相位变化）的估计带来很大的不利。
4) Kondo problem
