沈义荣孤子是一种孤波，有时可以在水渠中看到，也可以作为光脉冲在光纤中出现，它们可以在不改变形状的情况下长距离传播。这种现象是波的弥散趋势和传播介质的非线性特性之间微妙平衡的结果。这种相互作用的结果是，孤子的数学描述可能非常复杂。在他的观点中，沈讨论了Snyder和Mitchell在同一问题上的一份报告，该报告展示了一种更简单的数学方法来处理孤立子。
Y.R. Shen Solitons are solitary waves, sometimes seen in water canals or as light pulses in optical fibers, that propagate for long distances without changing shape. This phenomenon is the result of a delicate balancing act between the tendency for waves to disperse and the nonlinear properties of the propagation medium. As a result of this interaction, the mathematical description of solitons can be highly complex. In his Perspective, Shen discusses a report in the same issue by Snyder and Mitchell that shows a much simpler way to mathematically approach solitons.
