标题[请益] 这段原文 看得有点雾煞煞@@

最近这阵子 闲来没啥事
跟同学在学校的资料库中看一些paper的摘要
其中看到一篇的结尾部分觉得怪怪的,如下:
We consider a price adjustment process in a model of monopolistic competition
. Firms have incomplete information about the demand structure. When they set
a price they observe the amount they can sell at that price and they observe
the slope of the true demand curve at that price. With this information they
estimate a linear demand curve. Given this estimate of the demand curve they
set a new optimal price. We investigate the dynamical properties of this
learning process. We find that, if the cross-price effects and the curvature
of the demand curve are small, prices converge to the Bertrand-Nash
equilibrium. The global dynamics of this adjustment process are analyzed by
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
numerical simulations. By means of computational techniques and by applying
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
results from homoclinic bifurcation theory we provide evidence for the
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
existence of strange attractors.

奇怪的吸引因子??
就是上面划线的部分觉得颇难懂的,跟同学两人讨论来讨论去的,不由自主地搞笑起来~XD
(虽然前面的部分也没全然很了解,但最起码前面部分的文字"看"得懂~:p)
不知有没有人看的懂这段文字,能帮忙解惑一下的~thx!!
