希望达成的：ave_breath_duration动态赋值，填入rr.v数组
实际上：ave_breath_duration的值固定，rr.v循环出一样的值
该回答引用GPTᴼᴾᴱᴺᴬᴵ
根据提供的代码，ave_breath_duration 是在 for 循环中计算得到的，然后用来计算 rr.v(win_no)。在每个 for 循环迭代中，都会重新计算 ave_breath_duration 的值，因此它是动态赋值的。
·
但是在代码中，计算 ave_breath_duration 的语句放在了 for 循环的内部，每次循环迭代都会重新计算一次 ave_breath_duration，而在每次迭代中，ave_breath_duration 只被用来计算一次 rr.v(win_no) 的值，所以在每个迭代中，ave_breath_duration 的值并没有在其他地方使用或保存。
·
因此，在 rr.v 中出现相同的值可能是由于其他变量或输入数据的问题，或者是代码逻辑的错误。建议检查输入数据和其他变量的值，以及代码的逻辑是否正确。同时，可以添加调试输出语句以帮助调试程序。
