QMR的双语例句

1、CGS and QMR methods are easily broken off;

CGS和QMR方法易于中断；

2、The algorithm uses the inexact search directions that are computed with only moderate accuracy by Krylov subspace methods like CG or QMR.

该算法使用的搜索方向仅需要达到一个相对的精度，这样的搜索方向可以通过Krylov子空间迭代法，比如CG或QMR得到。

3、To the railway signal control system, the quadruple modular redundant ( QMR) architecture meet the higher safe requirement because of the busier railway transport and the higher train speed.

四模冗余结构满足铁路运输日益繁忙和列车速度不断提高对铁路信号控制系统更高的安全要求。

4、This article addresses the technical advantages of QMR safety system in aspects of agent structure of the system, operation principle, function of Integrated Safety Shutdown, and function of failure auto-diagnosis.
