Firstly, several key technologies used in the current OBP systems are analyzed in this paper.

论文首先分析和比较了当前用于星上处理的几大关键技术。

We first get an effective algorithm for generalized inversion of a matrix, i. e. OBP algorithm. The exact generalized inversion of a matrix is obtained after finite steps by using OBP algorithm.

先得到计算矩阵的广义逆的一种有效算法，即正交反向传播（OBP）算法，利用OBP 算法，经有限次迭代即可以得到矩阵广义逆的精确解。

But if he repeats his 2011 season, in which he had a .344 OBP in 512 plate appearances, Jones's career OBP would land at .399.

His .331 OBP and .373 SLG are both career lows.
