雨流计数法又可称为“塔顶法”,是由英国的Matsuiski和Endo 两位工程师提出的, 距今已有50 多年。雨流计数法主要用于工程界, 特别在疲劳寿命计算中运用非常广泛。把应变-时间历程数据记录转过90°,时间坐标轴竖直向下, 数据记录犹如一系列屋面, 雨水顺着屋面往下流, 故称为雨流计数法。雨流计数法对载荷的时间历程进行计数的过程反映了材料的记忆特性，具有明确的力学概念，因此该方法得到了普遍的认可。(The rain stream counting method, also known as the tower top method, was proposed by two engineers in the UK, Matsuiski and Endo, for more than 50 years. The rain flow counting method is mainly used in the engineering field, especially in the calculation of fatigue life. Record the strain time history data by 90 degrees, and the time axis is vertical downward. The data record is like a series of roof. The rain water flows down the roof, so it is called the rain flow counting method. The counting process of the rain flow counting method reflects the memory characteristics of the material and has a definite mechanical concept. Therefore, this method has been widely accepted.)

子类方法不可比父类方法抛出更多的例外。子类抛出的例外或者与父类抛出的例外一致，或者是父类抛出例外的子类型。或者子类型不抛出例外。(Class methods are not comparable to the parent class method throws more exceptions. The subclass thrown exception or thrown with the parent class exceptions, or the parent class throw exception sub type. Do not throw exceptions or sub type. )

实验器材: 探索者STM32F4开发板 实验目的: 学习DS18B20数字温度传感器的使用. 硬件资源: 1,DS0(连接在PF9) 2,串口1(波特率:115200,PA9/PA10连接在板载USB转串口芯片CH340上面) 3,ALIENTEK 2.8/3.5/4.3/7寸TFTLCD模块(通过FSMC驱动,FSMC_NE4接LCD片选/A6接RS) 4,DS18B20传感器一个(接在PG9上). 实验现象: 本实验开机的时候先检测是否有DS18B20存在，如果没有，则提示错误。只有在检测到DS18B20之后才开始 读取温度并显示在LCD上，如果发现了DS18B20，则程序每隔100ms左右读取一次数据，并把温度显示在LCD 上。同样我们也是用DS0来指示程序正在运行。(Experimental equipment: Explorer STM32F4 development board Objective: Learn the use of DS18B20 digital temperature sensor. Hardware resources: 1, DS0 (connected to PF9) 2, serial port 1 (baud rate: 115200, PA9/PA10 connection on board USB to serial port chip CH340). 3 inch TFTLCD ALIENTEK, 2.8/3.5/4.3/7 module (via FSMC driver, FSMC_NE4 LCD chip select /A6 RS) 4, one of the DS18B20 sensors (attached to PG9). Experimental phenomena: This experiment first detects whether there is DS18B20 when starting up. If not, it prompts errors. Only after the detection of DS18B20 did it begin Read the temperature and display it on LCD. If DS18B20 is found, the program reads data once every 100ms or so and displays the temperature at LCD. On. Similarly, we also use DS0 to indicate that the program is running.)
