接下来是需要修改的程序，请根据上面程序的内容，修改下面程序的数据采集后的部分，仿照上面的程序在测试后建立测试集，选中测设集可以导出为excel文件。不要修改原界面布局，界面中间部分的下方空白处放的是采集的数据，右上方的空白处显示数据集，将“导出全部为json”改为“导出为Excel”，点击此按钮即可导出excel文件，其他的部分仍要保持原样

博客围绕多线程编程展开，给出了多线程计数代码示例，包括线程定义、启动等操作。同时指出在某些线程执行时关闭窗体，因线程对文本框操作引发异常，还探讨了有线程运行时简单强行关闭应用程序的问题，使用join会使程序挂起。
注意：windows程序测量时间间隔精度大于毫秒，以至于sleep(1) and sleep(10)将提供相同的时间间隔。
