主要计算声学里的 A计权中各频率点的修正值，自动计算得出修正值。(It mainly calculates the A weight of the acoustics, the correction value of each frequency point, and automatically calculates the correction value.)

说明：  下垂控制就是选择与传统发电机相似的频率一次下垂特性曲线（Droop Character）作为微源的控制方式，即分别通过P/f下垂控制和Q/V下垂控制来获取稳定的频率和电压，这种控制方法对微网中的微源输出的有功功率和无功功率分别进行控制，无需机组间的通信协调，实现了微源即插即用和对等控制的目标，保证了孤岛下微电网内电力平衡和频率的统一，具有简单可靠的特点(Droop control is to choose Droop Character, which is similar to the traditional generator, as the control mode of micro-source, that is, to obtain stable frequency and voltage through P/f droop control and Q/V droop control respectively. This control method controls active power and reactive power of micro-source output in micro-grid separately, without communication coordination between units. The goal of micro-source plug-and-play and peer-to-peer control is realized, which ensures the unification of power balance and frequency in the micro-grid under isolated islands, and has the characteristics of simplicity and reliability.)

说明：  在一个有向无环图中求最长路径，利用了拓扑排序(Finding the longest path in a directed acyclic graph by using topological ordering)

说明：  51单片机实现数码管流动；通过c语言实现数码管流动和闪烁；(51 single chip digital control flow by c language movement and flashing LED )
