Cogwheel phase cycles are often significantly shorter than traditional nested phase cycles. However, optimal solutions for cogwheel cycles are often difficult to find. This paper presents techniques and conjectures which the authors have found useful for generating cogwheel phase cycles either without the need for computer searches or with significantly smaller searches than would otherwise be necessary. The conjectures presently lack proofs but have been tested successfully for a large number of cases.
齿轮相位循环通常比传统的嵌套相位循环显著更短。然而，齿轮循环的最优解往往很难找到。本文介绍了一些技术和推测，作者发现这些技术和推测对于生成齿轮相位循环很有用，要么无需计算机搜索，要么所需的搜索量比其他情况显著更小。这些推测目前缺乏证明，但已在大量案例中成功测试。
