At first blush, you might think that you could simply cascade two counters together using the carry-out pin, Pin 12, from one counter to feed the clock-input pin, Pin 14, of a second counter.
初看上去，也许会考虑使用动作管脚（管脚12）从一个计数器接到第二个计数器的时钟输入管脚（管脚14），简单的级联两个计数器。
The system could carry on the single-series refrigeration cycle, double-series refrigeration cycle and cascade refrigeration cycle through the designed regulating station.
通过设计的调节站，该装置可以进行单级制冷循环、双级制冷循环以及复叠式制冷循环。
