仿真程序数控机床，数控机床，以模仿实际操作，有有一定的价值，很多共享！,可以直接使用。 (Simulation program CNC machine tools, CNC machine tools, to mimic the actual operation, the value of many shared Can be used directly.)

超声波测距，在51单片机内核下的超声波测距程序，比较精简，希望大家受用。(Ultrasonic ranging, in 51 single kernel of ultrasonic distance measurement procedures, more streamlining, I hope everyone is good enough.)

根据设计任务书的要求，本次设计为110kV 变电站电气一次部分初步设计，并绘 制电气主接线图及其他图纸。该变电站设有两台主变压器，站内主接线分为110kV、 35kV 和10kV 三个电压等级。各个电压等级分别采用单母线分段接线、单母线分段带 旁母接线和单母线分段接线(From the guide of engineering design assignment, we have to design primary power-system of 110kV substation and draw main electrical one-line diagram and others. There are two main transformer in the substation in which main electrical connection can be divided into three voltage grades: 110kV, 35kV with 10kV.It deposits sectionalized single bus bar scheme, sectionalized single and transfer bus bar and sectionalized single bus bar scheme per grade.)

此程序可实现长度为8位，周期为255的m序列，此序列可当做伪随机信号发生器，模拟信道噪声。(This procedure can achieve the length of 8 bits, the m sequence of 255 cycles, the sequence can be used as a pseudorandom signal generator, analog channel noise.)

SSD6实验，该实验练习指导如何分析测量程序的性能。这个实验完成后，你应该能够  理解如何测量程序的运行时间、  调整你的计划，以更快的知道的重要性(This laboratory exercises guide you how to measure the program’s performance using profiling. On completion of this laboratory, you should be able to  Understand how to measure the program’s running time  Be aware the importance of tuning your program to be faster)
