本文提出了改进的机构回路和分支的定义，并讨论了其在平面连杆机构中的应用。介绍了平面多环连杆机构回路和分支识别的难点。不同作者使用的命名法与这里提出的定义相关。通过证明满足已发表的“分支"标准的机制实际上可能需要拆卸才能到达所有期望的位置，从而使它们在实践中无用，说明了将电路与分支混淆的危险。此外，电路内的分支的变化被示出与某些应用无关。
Improved definitions for circuits and branches of mechanisms are proposed and discussed in application to planar linkages. The difficulty of circuit and branch identification of multi-loop planar linkages is introduced. The nomenclature used by various authors is correlated with the definitions proposed here.The danger of confusing circuits with branches is illustrated by demonstrating that mechanisms satisfying published ''branch '' criteria may actually require disassembly to reach all desired positions, rendering them useless in practice. Furthermore, a change of branch within a circuit is shown to be irrelevant to some applications.
