As Stephen Schneider, a climatologist at the National Centre for Atmospheric Research puts it, It is often said that we do not so much inherit the world from out forebears, but rather we borrow it from our children.

国家气象研究总局的气候学家Stephen Schneider提出，我们不是从我们的祖先那里继承了这个世界，而是在向我们的后代借。

"These areas are most susceptible to climate warming in the coming century in Antarctica, because they are the closest to the melt threshold," says climatologist Andrew Monaghan of the National Center for Atmospheric Research in Boulder, Colo., who was not involved in this study but reviewed the research.

"在下个世纪，南极沿海地区是南极洲最容易受到气候变暖影响的地区，因为这些地区最接近融化的极限，"科罗拉多州博尔德市美国国家大气研究中心的气候学家安德鲁·莫纳汉说。莫纳汉没有参与这项研究，但是对该研究作了评论。

Nowadays, most of research are to build a transmutative Petri Nets through adding controlling place sets, controlling arc sets and controlling policy to the basic Petri Nets, while the Controlled Petri Nets could be used to argue many controlling theory problems conveniently and to induce many logically and physically supervisory and solve the Event Feedback Controlling Problems and State Feedback Controlling Problem in DEDS supervisory theory.

目前大多数的研究表现为在变形后的受控Petri网基础上，利用各种方法求得各种逻辑型、结构型控制器，解决DEDS监控理论中的事件反馈控制问题与状态反馈控制问题。
