这些研究资料为进一步阐明上皮细胞永生化的分子机制、建立人鼻咽上皮细胞永生化模型提供实验依据。

Therefore, it is imperative that you need to be prepared for the great change that is about to occur.

In this project, we intend to combine the above mathematical ideas. First, we consider a wild family of dynamical systems which can be derived into a family of difference equations. Then using a generalized version of the implicit function theorem which we will establish, we want to show that for any dynamical systems near 「singular limit」, there exists a horseshoe structure and hence chaotic phenomena occur.

在此研究计画中，我们打算结合上述的数学结论与想法，进一步考虑一类能够转化成差分方程的动态系统函数族，使用即将建立的推广性隐函数定理，我们希望证明当参数接近奇异极限时，动态函数会具有马蹄结构所以有混沌现象。

In addition, as we'll see in Chapter 7, implicit conversions also occur during function calls.

另外，在函数调用中也可能发生隐式类型转换，我们将在第七章学习这方面的内容。
