single-roll flow pattern(【参】勿按字面意思将 single-roll flow pattern 翻译成"单辊流动模式"或"单滚动流动模式"。根据连铸专业知识和查阅相关专业文献进行论证，即可以确定single-roll flow pattern 准确、规范的汉语译名是汉语连铸文献中的"单环流流动模式"。: ① In the single-roll flow pattern, steel from SEN first goes upward, and meniscus velocities go from the SEN to the narrow face： 在单环流模式下，由浸人式水口流出的钢水首先向上流动，此时金属弯月面的速度方向为由浸人式水口指向结晶器窄面。② Injection of gas makes the flow more turbulent and causes the transition from double-roll to single-roll flow pattern. 喷人气体使流动更加紊乱，同时引起双环流流动模式向单环流流动模式转变。)
