In Chapter 2, we study the effects of birth pulses on the dynamical complexity of stage-structured discrete models. Firstly, we propose and study the single-species discrete population model with stage structure and birth pulses.
在第二章,我们研究了密度依赖生育脉冲对单种群阶段结构离散模型的动力学行为的影响。

But Barthes has entered a phase of his career in which you actually think that structures are so complex that they cease to be structures and that this has a great deal to do with the influence of deconstruction.
但是巴特已经进入了事业的一个阶段,这时你会认为结构非常复杂而不想继续研究结构了,这就对解构主义产生了很大的影响。
This Cambridge History of Food talks about three separate primary phases in human food evolution: one beginning a million and a half years ago, another about 700,000 years ago, and then the 10,000 year ago one that I talked about just a moment ago.
