开始互殴

As once-distinct markets start to overlap, chipmakers come to blows

Self disarms him and they engage in a savage fistfight.

赛尔夫打掉了他的武器，他们开始了凶猛的互殴。

To step in is to become involved. For example,"The coach wanted to let the team work out their own problems on the court, but after getting beat badly in the first quarter, he decided to step in," or "I let them argue, but had to step in when they started punching each other."

step in」就是介入、干预的意思，例如：「教练本来想让球队在球场上自行发挥，但他们第一节被对手痛宰后，教练就决定出手指导」，或是「他们争论的时候我没有插手，但他们开始互殴时我就不能坐视不管了」。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
