实验原理

1.5分

[实验原理]

硅压阻力敏传感器的工作原理：基于半导体的压阻效应，当传感器受到拉力作用时，其电阻值发生变化，通过电路转换为电压信号输出，电压变化与所受拉力成正比，经砝码定标后可获得灵敏度B

拉脱法测量液体表面张力系数的核心原理：液体表面层分子间存在相互作用的表面张力，当金属圆环与液体表面接触并缓慢拉脱时，表面张力会阻碍圆环脱离液体，此时传感器测量的拉力与表面张力平衡。

实验仪器如下

实验步骤

1分

[实验步骤]

1)开机预热。

2)测量吊环的内、外径。

3)清洗实验材料。

4）在玻璃器皿内放入被测液体，并将玻璃器四安放在升降台上。

5）将砝码盘挂在力敏传感器挂钩上。

6）若整机已预热 15 min 以上,可对力敏传感器定标，在加砝码前应首先对仪器调零,安放砝码时应尽量轻。

7）将吊环挂在力敏传感器的挂钩上。在测定液体表面张力系数过程中，观察液体产生的浮力与张力的情况及现象。顺时针转动升降台大螺帽时液体液面上升,当环下沿部分均浸人液体中时,改为逆时针转动该螺帽,这时液面往下降(或者说相对的吊环往上提拉)，观察环浸人液体中及从液体中拉起时的物理过程和现象,也可以用手机拍摄这一过程的录像。应特别注意吊环即将拉断液柱前一瞬间数字电压表读数值 U，拉断时数字电压表读数 U。记下这两个数值。

七、溶液浓度与液体表面张力系数的关系

0.2分

做溶液表面张力系数-溶液浓度关系曲线图（此处视纯水的浓度为0%）。

得分：0.2 分

在数据处理中，我们已经计算出了测力计的灵敏度的不确定度，以及吊环内、外径的不确定度等。试在“实验分析”中给出表面张力的合成标准不确定度，并写出表面张力的完整表达形式。
