模拟版图的艺术，layout，区别于普通的pcb版图。属于微电子行业的设计，相关工具有laker、cadence等等(The art of analog layout, layout, layout pcb from ordinary. Belonging to the design of micro-electronics industry, the relevant tools laker, cadence, etc.)

单片机计算机设计，实现加减乘除，包括小数点的运算，用的是4*4的键盘(Single chip computer design, realization add, subtract, multiply and divide, including the operations of the decimal point, with 4* 4 is the keyboard)

步进电机是将电脉冲信号转变为角位移或线位移的开环控制电机，是现代数字程序控制系统中的主要执行元件，应用极为广泛。。在非超载的情况下，电机的转速、停止的位置只取决于脉冲信号的频率和脉冲数，而不受负载变化的影响，当步进驱动器接收到一个脉冲信号，它就驱动步进电机按设定的方向转动一个固定的角度，称为“步距角”，它的旋转是以固定的角度一步一步运行的。可以通过控制脉冲个数来控制角位移量，从而达到准确定位的目的；同时可以通过控制脉冲频率来控制电机转动的速度和加速度，从而达到调速的目的。(Stepper motor is an open loop control motor which transforms electrical pulse signal into angular displacement or linear displacement. It is the main executive element in modern digital control system, and is widely applied. In the case of non overloaded, the motor speed and stop position depends only on the pulse frequency and pulse number, regardless of load changes, when the stepper driver receives a pulse signal, it drives stepper motor to set the direction of rotation of a fixed angle, called "step", it is the rotation of the fixed point of the operation step by step. We can control the angular displacement by controlling the number of pulses, so as to achieve the goal of accurate positioning. At the same time, we can control the speed and acceleration of motor rotation by controlling the pulse frequency, so as to achieve the purpose of speed regulation.)

说明：  简单的流水灯控制和外部中断程序和键盘指针的应用(Simple light control and external interrupt water program and the application of the keyboard pointer)

说明：  　　 paek变换 park转换，也称派克变换，英文为Park transformation,为现在占主流地位的交流电机分析计算时的基本变换。在电力系统分析和计算中，park转换具有重要的理论和实际意义。(paek transform park conversion, also known as Park transformation, the English for the Park transformation, for the now dominant in the calculation of AC motor analysis of the basic transformation. In power system analysis and calculations, park conversion has important theoretical and practical significance.)

3． 参考void Reverse(LinkQueue &Q)函数，定义新的函数int Palindrome_Test(char str[])，判断字符串str是否回文序列,若是则返回1,否则返回0。写出程序或用文字描述算法的执行步骤。(3. Reference void Reverse (LinkQueue & Q) function, define a new function int Palindrome_Test (char str []), to determine whether the string str palindromic sequence, if it returns 1, otherwise it returns 0. Written procedures or describe in words the steps of the algorithm.)
