Through arguing against the historical mysticism and the practical deconstructionism, Eco proposes that the potential infinity of interpretation does not means that interpretation cannot be an objective entity, or that interpretation could extend as randomly as water.

艾柯从对于历史上的神秘主义和现实的解构主义批判中，认为如果说诠释存在着潜在的无限性，并不表明它没有一个客观的对象，也不是说它可以像流水一样毫无约束地任意"蔓延"。

Similar to Debye screening in QED, at sufficiently high density we expect colour screening to set in and the potential does not go into infinity as r increases. Color screening thus transform a color insulator into a color conductor, turning hadronic matter into a quark matter, where the interactions between quarks and gluons become relatively weak and long range.

1引言在随机控制问题中，常常要求设计一个控制器使得不同的系统子状态具有确定上界的方差值E。

First, a new integral inequality for quadratic terms is established by using the Park inequality. Next, the integral inequality in combination with the Lyapunov-Krasovskii functional method is used to derive a new delay dependent sufficient condition based on LMI which can guarantee that the closed-loop system is not only internal asymptotically stable but also with the prescribed H-infinity performance via the slow subsystem's memoryless state feedback.

首先利用Park不等式建立了一个基於二次型项的积分不等式，然后利用Lyapunov-Krasovskii泛函方法，获得了系统经慢子系统的无记忆状态反馈后不仅内部稳定，而且具有给定的H性能的，基於LMI的时滞相关充分条件。

Barsky[4 ] 将具有张力参数样条的双曲样条曲线引入CAGD ，称之为张力样条参数曲线，并证明了这种曲线是一类泛函问题的极小解。

It is shown that two-component Wadati-Konno-Ichikawa equation, i.e. a generalization of the wellknown WKI equation is obtained from the motion of space curves in Euclidean geometry, and it is exactly a system for the graph of the curves when the curve motion is governed by the two-component modified Korteweg-de Vries flow. At the same time, a n-component generalization to the WKI equation is obtained. Also, starting from the motion of curves, mKdV and its symmetry recursion operator is exhibited explicitly; two- and n-component mKdV systems are obtained. It is shown that WKI systems are gauge equivalent to mKdV systems. The two-component WKI equation admits an infinity number of conservation laws and a recursion formula for the conserved densities is given by considering an eigenvalue problem together with introducing an appropriate transformation.
