英语翻译
1.Binary System
A digital system functions in a binary manner.It employs devices which exist only in two possible states.A transistor is allowed to operate at cutoff or in saturation,but not in its active region.A node may be at a high voltage of,say,4±1V or at a low voltage of,say,0.2±0.2V,but no values are allowed.Various designations are used for these two quantized states,and the most common are listed in Table 3.1.In logic,a statement is characterized as true or false,and this is the first binary classification listed in the table.翻译到这里就行了,
这段讲的是二进制和举了2个相关例子,像第二句,就应该翻译成晶体管可以工作在其截止区和饱和区,而不是其放大区.这句我懂,主要是要知道下一句的意思是什么.
第三句的意思应该是 一个节点可能处于高压电,比方说:4±1V或者处于低压电,比方说0.2±0.2V,但是没有确定值也是呗允许的.
再问: 没有确定值也是被允许的,怎么理解?
再答: 结合该句上文的意思,这句话的意思应该理解为:有些问题只需要确定其处于高低压或者低电压,而不需要其准确值是什么。
