    • A computer-implemented method to access a data structure including a tree data structure in a computing environment. The method includes generating the data structure in the computing environment. The tree data structure includes a plurality of nodes, a node in the plurality of nodes embodying a plurality of fields, and at least one child link and at least one next link, the at least one child link and the at least one next link being used to link two or more nodes in the plurality of nodes. The method further includes accessing contents of the data structure with an access command in the computing environment. The access command includes a reference to at least one node of the tree data structure and a user-defined argument.

    • A polycrystalline abrasive composite cutter, including a tool body with a top cutting surface and a flank surface. The composite cutter, joined to a substrate, constitute a shear cutter for a PDC bit, roller-cone bit insert, or other tool that can be highly useful for petroleum drilling or other applications. The body of the polycrystalline abrasive composite cutter includes a plurality of polycrystalline abrasive layers (90) and a plurality of arresting layers (100). The polycrystalline abrasive layers (90) and the arresting layers (100) are arranged to alternate throughout the tool body in a direction normal to the top cutting surface (92) and in a direction normal to a flank surface (94). According to the design, the arresting layers (100) can be oriented so as to substantially arrest crack propagation through the polycrystalline abrasive material.
    • 一种多晶磨料复合切割机,包括具有顶切割表面和侧面的工具主体。 复合切割机连接到基片上构成用于PDC钻头,圆锥钻头刀片或其他可用于石油钻井或其他应用的刀具的剪切刀。 多晶磨料复合切割机的主体包括多个多晶磨料层(90)和多个止动层(100)。 多晶磨料层(90)和止动层(100)被布置成沿着垂直于顶切割表面(92)的方向并且在垂直于侧面(94)的方向上在整个工具主体上交替。 根据该设计,阻挡层(100)可以定向成基本上阻止通过多晶磨料的裂纹扩展。
