In the retail industry, the number of items available in stock is called the quantity on hand or QoH.

Furthermore, this paper concludes the 3 methodologies as one Quality Control and Management Framework: Quality of House ( QoH) model.

并且，本文最后对这三种方法进一步推广，提出基于开源的商业软件系统质量控制和管理框架&质量屋（QoH）模型。

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.

同样地，对求解非对称线性方程组的QMR方法作出了向后扰动分析，结合总体向后扰动范数拟极小化的技巧，给出了求解非对称线性方程组的总体拟极小向后扰动（TQMBACK）方法。

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.

从系统的主体架构、工作原理、一体化停车功能和故障自诊断功能4个方面阐述了四重化冗余安全仪表系统的技术优势及其设计步骤；

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。

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).

实验表明：与米非司酮组和对照组比较，加用祛膜汤1ml组早导大鼠第10天、第13天血浆孕酮含量显著降低（P＜0.05）。

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.

针对网络控制系统的闭环性能受网络调度QoS与控制性能QoP两个方面决定，采用基于QoS管理的兼顾网络调度QoS与控制性能QoP两方面的协同设计。
