1. 完成时／分／秒的依次显示并正确计数，利用六位数码管显示； 2. 时／分／秒各段个位满10正确进位，秒／分能做到满60向前进位，有系统时间清零功能； 3. 定时器：实现整点报时，通过扬声器发出高低报时声音； 4. 时间设置，也就是手动调时功能：当认为时钟不准确时，可以分别对分／时钟进行调整； 5. 闹钟：实现分/时闹钟设置，在时钟到达设定时间时通过扬声器响铃。有静音模式。 -1. Completed/min/sec display and correctly followed by counting, using six digital tube display 2. When/min/sec in the paragraphs of the correct 10-bit binary full, s/sub can do to advance the age of 60-bit, systematic function of the time cleared 3. timers: realize the whole point of time, by the time the level of sound from loudspeakers 4. time settings, which is manually adjusted when the function: When the clock does not consider accurate, they can respectively sub/clock adjustments 5. alarm clock: the realization of sub-/ when the alarm clock settings, settings in the clock arrival time ringing through the loudspeakers. There are silent mode.

在顺序存储结构中，利用编号表示元素的位置及元素之间孩子或双亲的关系，因此对于非完全二叉树，需要将空缺的位置用特定的符号填补，若空缺结点较多，势必造成空间利用率的下降。在这种情况下，就应该考虑使用链式存储结构。-Storage structure in order to use the element number that the location and elements of the relationship between children or parents, so for non-complete binary tree, the location of the vacancy will be required to use specific symbols to fill the vacancy if more nodes, it is bound to cause decline in utilization of space. In this case, we should consider the use of the structure of chain stores.
