Several nights ago, I'd heard that the Olympic torch relay was going to pass by Tsinghua University's west gate on the morning of the eighth.
几天前，我已经听说奥运会火炬接力将于八号早上经过清华大学西校门。

As a result of the simplification, we can now build much simpler logic circuits performing the same function, in either gate or relay form.
用简化后的结果，我们现在建立简单的逻辑电路来实现相同的功能，用其它门或设备组成。

By using gate control and SCR rectifier circuit instead of relay control system, it makes the unit smaller, cost lower, reliability higher and control function more accurate.
