This paper discusses such problems which are easily solved incorrectly in limitedteaching as, segment function is uncertain not to be elementary function, elementary function is un-certain to be continuous in its field of definition, unlimited variable is uncertain to be infinity, theinfinitely many infinitesimal is uncertain to be infinitesimal, the multiplication of two non- infinitesi-mal is uncertain not to be infinitesimal.

1分段函数不一定不是初等函数我们知道初等函数的定义是：常数和基本初等函数经过有限次的四则运算或复合，用一个解析式表示的函数叫初等函数。教材中的定义强调的"有限次"和"一个解析式"，使很多同学产生"非有限次"和"非一个解析式"的函数就不是初等函数的误解。例1f=ceox，s xx！0为分段函数，但也可以表示为f=e12(x-x2")+cos12(x+x2#"$)-1，故为初等函数。

In Chapter 5, some knowledge about large-scale system and methods for investigating them are introduced, Lyapunov function, differential inequality, Razumikhin theorem, matrix norm and measure methods have been used to discuss the stability of uncertain large-scale system with delays and decay estimates for uncertain time-varying large-scale system with delays, the criteria of stability and decay estimates for uncertain large-scale system with delays are given.

第五章首先介绍了大系统的有关知识以及时滞大系统研究的方法，然后利用Lyapunov函数法、微分不等式法、Razumikhin定理法、矩阵范数与测度法研究了不确定定常时滞大系统的稳定性以及不确定时变时滞大系统的稳定性与系统衰减率的估计问题，得到了系统稳定的判别条件以及系统衰减率的估计。

Based on the description of uncertain linear and area objects, intersection degrees for parts of uncertain linear and area objects are represented quantitatively. By calculating correlation degrees between spatial vectors composed of these measurement units and spatial relation vectors determined by 9-intersection model, a new model is presented for topological relations between uncertain linear objects and fuzzy region, which could distinguish the type of topological relations through quantitative analysis method.

在时不确定线状目标和面状目标进行描述的基础上，对不确定线状目标与面状目标各组成部分之间的相交程度进行了定量表达，通过计算这些度量组成的空间向量与9-交集模型确定的空间关系向量之间的相关度，提出了一种不确定线状目标和面状目标之间拓扑关系的描述模型，通过定量的方法来对其空间拓扑关系进行判别。

uncertain：不确定的

根据韦氏英语辞典的解释,不确定性(Uncertainty)是指"不确定的(Uncertain)的性质或状态","不确定的包括:不肯定的、不可靠的、模糊的、不稳定的、无规则的、变化无常的、偶然的等等".

uncertain：不确定

在发现理论中,创业者决定开发机会时的决策状态被假设为"有风险"(risky),而不是"不明确"(ambiguous)或"不确定"(uncertain). "有风险"、"不明确"和"不确定"这三个术语在很多场合可以相互替代,但为了区别发现理论和创造理论的假设前提,

uncertain：不确定性

概率可以帮助我们理解风险(Risky)和不确定性(uncertain). 风险与不确定性是互有联系的两个概念. 不确定性是指决策者不能肯定某种经济行为一定会发生某种结果,也不知道其发生的概率. 风险是指决策者虽然不能肯定某种经济行为一定会发生某种结果,
