The shielded rectangular cross section slab line with cylindrical inner conductors is of great importance to microwave engineering and design.
由多根圆柱内导体和矩形外导体所组成的屏蔽矩形板线是电磁工程中一类重要的传输线。
When the distance between the axis of the inner conductor and the bottom of the trough tends to infinity, the results obtained in this paper go into that of the well-known slab line.
当此槽形线底部与中心圆柱的轴线间的距离趋于无限大时，我们即得到人的所熟知的两平板间具有中心内导体的传输线的结果。
At the same time, accurate prediction of time meets the need of slab rolling production line, and slab has better heating quality and fuel consumption is lower.
同时准确的时间预测既保证了轧线对板坯产量的需求，又保证了板坯有较好的加热质量和较低的燃耗。
