计数器的型式很多,有机械式的,也有电子式的。我们所讨论的是电子式,因为它比起机械式有更大的优越,最明显的一点就是快速,目前已知它最快速度可达一千万次。它的用途也是极广泛,可以用来准确地测量频率,也可以用来计算短暂的时间,作为分频器等,对于生产过稗自动控制更是适合。为此我们对它进行了初步的研究,但由于水平关系,对它的了解还很缺乏,现在就将我们试制过程的体会作如下的叙述,希望大家指教。 There are many types of counters, both mechanical and electronic. We are talking about the electronic, because it is more superior than the mechanical advantages, the most obvious point is fast, it is currently known as the fastest speed up to 10 million times. Its use is also extremely broad, can be used to accurately measure the frequency, can also be used to calculate a short period of time, as a divider, etc., for the production of barnyard grass automatic control is more suitable. For this reason we conducted a preliminary study of it, but because of the horizontal relationship, its understanding is still lacking. Now we will experience the trial process as follows, I hope you enlighten.
