摘要： A stiffener rib for a non-cooled, hollow core airfoil of a turbine blade is described. The stiffener rib is constituted by an elongated solid metal piece dimensioned for securement in a hollow region of a core portion of the airfoil. The stiffener rib is shaped and oriented upwards from a leading edge of the airfoil at a predetermined calculated angle to minimize mode 2 deformation of the blade at a trailing edge thereof while improving the rigidity of the turbine blade.

摘要： A method, system and computer program product for distinguishing superimposed links to a node in a drawing area. Links connected to a side of a node involved in an editing interaction are identified. The order of the identified links to be connected to the side of the node is determined by sorting the identified links based on the coordinates of the links' bend point and/or opposite end point. The connection points of these identified links are repositioned based on this determined order. By only repositioning the connection points to the node involved in the editing interaction instead of rerouting all of the links in the diagram area, the processing time is improved. Furthermore, by repositioning the connection points that were superimposed so that they are spaced apart based on the coordinates of the links' bend point and/or opposite end point, it is easier to distinguish between the different links.
摘要翻译：一种方法，系统和计算机程序产品，用于将叠加的链接区分到绘图区域中的节点。识别连接到参与编辑交互的节点的一侧的链接。通过基于链接的弯曲点和/或相对端点的坐标对所识别的链接进行排序来确定要连接到节点侧面的所识别的链接的顺序。这些确定的链接的连接点根据这个确定的顺序重新定位。通过将连接点重新定位到编辑交互中涉及的节点而不是重新路由图区域中的所有链路，处理时间得到改善。此外，通过基于链接的弯曲点和/或相对端点的坐标重新定位叠加的连接点使得它们间隔开，更容易区分不同的链接。
