灭绝的

First, in Chapter 3, a two-dimensional interacting birth-death process is established and by means of two-dimensional moment generating function, the equivalence in mean between our model and the classic prey-predator model are proved.

这部分包括第三，四章。在第三章，我们建立了一类新的随机捕食-被捕食模型，并证明了新模型在平均意义上与经典的捕食-被捕食模型的等价性，讨论了其灭绝性，平衡态分布等。

It's also interesting to muse about the implications of the extinction of so much that we've become very used to in our lives...

这也是很有意思的缪斯约的影响，灭绝了这么多，我们已经变得非常习惯在我们的生活中。。。

From then on plenty of work had been done to research the periodic solution and stability of ordinary differential equation.

Author suggest that established system of Eco-toxicology in Paleoecology, to prevent toxicant into body for us, to against foreign living intrude , to study Eco-toxicology and that established principles of law to protect from ecological safety, living things safety and food safety for our country and people.

作者就研究恐龙灭绝对我们今天的意义提出了一些新的见解，认为"中毒说"丰富了古生态学，为建立古生态毒理系统提供了依据；启示我们谨防生活中的毒物，严防境外有毒有害生物入侵，加强生态毒理学研究，进一步健全法律保障体系，确保生态安全，生物安全和食品安全。

Paleontologist Dave Raup postulates that 75 percent of all extinction events were caused by asteroid impacts.

设若地球上的所有物种都没灭绝，今天的芸芸众生会是怎样的？
