To use linear program, we have to take care of two problems. The first problem is that the actual relationship between intensity and duration is nonlinear convex function. In this study, we propose to use piece-wise linear curve to approximate the nonlinear convex curve. The second problem is that there are many feasible event sequences.

使用线性规划遭遇的困难有二：第一，作业强度与作业时间呈非线性之凸函数关系，因此本研究将使用片段线性曲线(piece-wise linear curve)近似作业强度与作业时间呈非线性之凸函数关系；第二，专案有很多组可能事件顺序，事件顺序的不同会产生不同的资源限制式，本研究提出一个系统化的方法求解问题。

But, as always, there are some daunting details to sort out first.

但和以往一样，有很多细节性的困难需要解决。

You have any difficulty, I can be glad to help you very much.

By the General Digraph, you can construct fault trees automatically not only for simple control systems but also for complex control systems.

使用这一方法，不但能较好地完成简单控制系统的自动建树，而且可以较好地完成有较复杂控制结构的控制系统的自动建树，克服了传统有向图法自动建树的困难。

When diphtheritic inflammation begins in the respiratory tract, sore throat and fever usually develop. Prostration and dyspnea soon follow because of the obstruction caused by the membrane.This obstruction may even cause suffocation if not promptly relieved.

当白喉在呼吸道引起炎症时，通常有咽喉痛和发热，然后由于假膜的阻碍会感到虚脱和呼吸困难，如果不及时治疗可能会引起窒息。

The split between the two groups can hardly be papered over.

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
