管线配套焊丝钢生产缓冷工艺研究 总被引:1,自引:0,他引:1
通过测定焊丝钢冷却过程连续过冷曲线,制定了管线配套焊丝钢盘条的冷却工艺。通过调整冷却工艺参数,使盘条强度满足了用户要求。拉拔试验结果表明,盘条可以不经过热处理直接拉拔到用户要求线径,拉拔后焊丝满足了用户缠绕与送丝要求。 相似文献

Capital project development is a complex process that takes many years to implement. The development of a capital project usually undergoes several rounds of design evolution, and as a result the basic and original customer’s requirements may be easily sidetracked or may deviate from the client’s objectives. Quality function deployment (QFD) is a tool that can be used to keep track of customers’ requirements. The objective of this paper is to explore the applicability of QFD in the civil engineering capital project planning process by developing a QFD model with an application template for the process. To verify and demonstrate how the QFD model works, data are obtained from two real-life projects and fed into the template for back-analysis. The findings suggest that QFD can be successfully used in the capital project planning process as a road map to keep track of the original requirements, facilitate good communication across the hierarchy, and serve as a tool for evaluating project alternatives. 相似文献

A standard criterion for judging the value of a psychotherapy process component (e.g., reflection of feeling) is the degree to which it correlates with outcome measures. It is argued that this model overlooks wide variation in client requirements for particular process components and therapist responsiveness to those requirements. Any such responsiveness tends to attenuate (and may even reverse) the process–outcome correlation. Under optimum conditions, process components covary responsively with client requirements but not with outcomes. Deviations from optimum would not improve outcomes. Thus, for expertly conducted therapy, the expected correlation of process components with outcomes approaches zero, even for components that help to cause those outcomes.
