3、原创技术文章：VB 编程制作实验数据处理软件。
思路：
（1）读取txt文本。txt文本里为以","隔开的两列数据，前一列为时间，后一列为光电流的值。
（2）提取特征数值，即每隔50 s 提取一个数值，而这一个数值为附近3个数值的平均值。
（3）进一步处理数值。隔100 s的两个数值之和的1/2减去中间50 s 的点的数值，得到一个实验结果数据。以此计算出不同时间的实验数组。
（4）由于数值存在负值和正值，统一对他们求绝对值。
（5）对（4）中求的值，取平均值，得到最终的实验结果。
（6）点击一次txt文本经历（1）-（5）步骤得到一个实验结果。只要依次点击一组txt就能求得一组实验数据。
（7）对于实验数据进行三种显示。1），作点线图（第（4）步数据）；2），在text文本框中集中显示，以便复制与直观比较；3），可以点击保存按钮将一组实验结果保存到以原始数据txt文件名 & 当前时间的为名的txt文件中，以便于在origin 文件中进行作图。操作界面：
