"行波传送进位" can be translated as "ripple-carry propagation" or more specifically in the context of digital circuits as "ripple-carry addition" (when referring to the addition process that utilizes ripple-carry).
Ripple-carry propagation emphasizes the process by which the carry signal propagates through each stage of a multi-bit adder.
Ripple-carry addition is a broader term that encompasses the entire addition operation using a ripple-carry mechanism.
In technical contexts, especially within digital electronics or computer architecture, both terms are commonly used, with the choice depending on the specific focus of the discussion.
