When solving the nonsymmetric linear systems, the paper makes the total backward perturbation analysis to QMR method, and uses the total quasi-minimal backward perturbation ( TQMBACK) technique. So the restarted total quasi-minimal backward perturbation ( RTQMBACK) method is given.

The transpose-free QMR ( TFQMR) algorithm is a Krylov subspace algorithm that can be used to obtain fast solutions for linear systems with very large and very sparse coefficient matrices.

TFQMR算法是一种Krylov子空间算法，常用来求解大型稀疏线性方程组。

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.

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。

CGS and QMR methods are easily broken off;

CGS和QMR方法易于中断；

The animal experiments shoWed that, in comparison with those in Mifepristone group ( group B) and control group ( group A), plasma progesterone levels decreased significantly in early pregnant SD rats in QMT group ( Mifepristone+ QMT, group C).

Although the "qualified majority voting" ( QMV) mechanism was introduced, but its scope was strictly limited. In addition, the development of EU independent defense is deeply affected by the lack of military capability of EU.

虽然引入了特定多数表决机制，但其适用范围也被严格的限制；其三，欧盟自身的军事能力不足也深深影响了欧盟独立防务的建设。

Due to the closed loop performance of networked control system decided by the quality of service and the quality of performance, the co-design strategy based on QoS management that considers both QoS and QoP is put forward.
