When the matrix equation is consistent, its centrosymmetric solution can be obtained within finite iterative steps in the absence of round off errors for any initial centrosymmetric matrix X1, and its least-norm centrosymmetric solution can be derived by choosing a suitable initial iterative matrix.

当矩阵方程AXB+CXD=F有中心对称解时，在有限的误差范围内，对任意初始中心对称矩阵X1，运用迭代算法，经过有限步可得到矩阵方程的中心对称解；选取合适的初始迭代矩阵，还可以迭代出极小范数中心对称解。

CD34 hematopoietic stem/progenitor cells reside in the bone marrow in close proximity to the endosteal bone surface, surrounded by osteoblasts, stromal cells, and various extracellular matrix molecules. We used a bioartificial matrix of fibrillar collagen I, the major matrix component of bone, as a scaffold for ex vivo expansion of HSCs.

Moreover, the matrix effect was investigated. The results showed that samples could be completely decomposed by melting in lithium tetraborate and lithium carbonate mixed flux at about 1000℃. The introduction of lots of lithium and matrix magnesium in solution affected the determination, which could be corrected by matrix matching. Calcium, iron and aluminium with high content had no spectral interference with other elements with low content.

结果表明，样品用四硼酸锂和碳酸锂混合熔剂在1000℃左右的温度下熔融，可以完全分解试样；引进试液中大量锂和基体铁时测定有影响，用基体匹配的方法克服，含量较高的钙、铁和铝对含量低的其他元素没有光谱干扰。
