Comparing with double dams, the tundish fixed with baffles has a similar minimum residence time, but a less dead volume. 导流挡板与双挡墙比较，最短停留时间变化不大，但死区体积更小。
The principle of this method is introduced in detail,and a kind of circuit of generating dead time and its timing simulation are given. 详细叙述了该方法的基本原理，并以其中的一个死区时间产生电路为例，介绍了电路的设计要点及时序分析。
