必修课38理论10实验主要内容传感器的组成开环测量系统系统1.随机误差的处理在相同条件下对某个量重复进行多次测量排除系统误差和粗大误差后如果测量数据仍出现不稳定现象则存在随机误差在等精度测量情况下得到n个测量值x1x2…xn设只含有随机误差?1?2…?n这组测量值或随机误差都是随机事件可以用概率数理统计的方法来处理随机误差的处理目的就是从这些随机数据中求出最接近真值的值对数据精密度的高低(或可信度
2.图形的翻折平移和旋转的异同:1相同:都是一种运动运动前后 不改变图形的形状和大小直线B例1:△ABC是等边三角形 △ABP顺时针旋转后能与△CBP重合那么(相当于书上的例1)巩固练习:1四边形ABCD是正方形△DCE顺时针旋转后与△DAF重合那么D旋转Your homework
