You learn it when you know that your evolution is never-ending and you potential for growth reaches to infinity.

LIMITLESSNESS The -final lesson you must learn is limitlessness,and it is the sense that there are no boun-daries to what you can become or do ,You lesrn it when you konw that you can evolution is never-ending and y-our potential for growth reaches to infinity.

承担责任是每个成年人的一门主修课。如果你还没有学会承担责任这课，现在还为时不晚。记住，生活会给你提供许许多多的机会去学会承担责任。

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。

Firstly, based on the Duhamel integral and dynamic reciprocity theorem, the generalized Duhamel integral expression is written to a point in the half infinity space under moving load. Secondly, the train load is considered as a series of centralized loads with fixed distance. The dynamic response expression of a point in frequency domain and frequencywavenumber domain are derived out through the Floquet transform and Fourier transform under a moving load, and then the dynamic response of a point is gotten ...
