一种方法是先优化得到结构功能函数的最大和最小值，再计算功能函数均值和离差的比值；

One method was getting the maximum and the minimum of the structural performance function by optimization, and then calculating the ratio of mean-value to deviation of the performance function.

如果可行，他就可以在几小时之内，用Python整洁的列表和字典等数据结构，以及列表理解(list comprehension)等整洁的函数编程功能来编写这个代码。

If it was possible he could write it within a few hours with Python's neat data structures such as list and dictionary, neat functional programming features such as list comprehension.

两个附加的函数为延迟任务提供相同的功能(其结构体装入结构体work_struct之中，并有一个计时器用于任务延迟)。

Two additional functions provide the same functionality for delayed work (whose structure encapsulates the work_struct structure and a timer for work delay).
