Generally speaking, those who discuss function 2 times to go up in interval most value, basically seeing interval is to fall on a which of 2 function drab interval, be begged thereby with corresponding monotonicity most value.

一般来说，讨论二次函数在区间上的最值，主要看区间是落在二次函数的哪一个单调区间上，从而用相应的单调性来求最值。

These constructional methods can be used to treat many problems, the numerical results show that the given interval extension has smaller excessive width relative to the range of the functions over a domain. For univariate differentiable functions, the definition of interval slope is extended from the first order to high order according to their differentiability, and iterative formula of high-order interval slope computation is also developed.

温度对于316L不锈钢钝化膜的半导体本征性质没有根本的影响：在-0.5~0.1V电位区间内钝化膜呈p型半导体特征；在0.1~0.9V电位区间内钝化膜呈n型半导体特征；在0.9~1.1V电位区间内钝化膜呈p型半导体特征。

In the final chapter, we discuss interval polynomial approximation of rational surfaces. Firstly, we briefly state the interval-surface approximation based on the Taylor Expansion, and later, we give out a better interval-surface approximation based on the optimization method, which is also the main work of this paper.

第四章主要介绍了有理曲面的区间多项式的逼近，首先简单介绍了基于泰勒展开来做的区间曲面逼近，后面是本文的主要工作，我们基于优化方法得到了更好的区间曲面逼近，它也是本文的重要部分。

For a given proportion p (where p is the confidence level), a confidence interval for a population parameter is an interval that is calculated from a random sample of an underlying population such that, if the sampling was repeated numerous times and the confidence interval recalculated from each sample according to the same method, a proportion p of the confidence intervals would contain the population parameter in question.

对于一个比例 P而言，一个群体参数的置信区间中的区间是由一个基础群体的随意样本计算出的，假如样本被重复了无数次，置信区间也根据每个样本，以同样的方法重新计算，那么这个置信区间中的比例 P 将要重新定论。

In this thesis, we present a new channel scan method called "random scan" to reduce the delay. The scheme divides the beacon interval into several sections. In each beacon interval, only one section will be scanned and it will take multiple beacon intervals to scan all the section to cover the entire beacon interval.

在本论文我们提出一个减少IEEE 802.11无线网路之漫游所造成服务中断的机制称为随机扫描，此机制将标记间隔切割成数个区段，在每个标记间隔中，只对一个区段进行扫描，剩下的时间可继续正常的传输，以降低服务被中断的时间。

The progress intervals between stages of the disease were estimated using left-censored and interval censored Markov chain models with a 6-year follow-up simulation. Results showed an annual preclinical incidence rate of 5.7 per 1000 for the high-risk group. The mean sojourn time was 1.90 years (95% CI=1.18-4.86). The proportion of interval case increased with the screening interval.

本研究自1995年至1996年10月止利用台湾地区12家大型医院，锁定出2629名高危险群妇女接受乳癌筛检，第一年筛检到的31名病病例之实证资料，推估得妇女乳癌之临床症前期发生率为每年每千人5.7人（0.0057/年），依据这些资料。

By representing the uncertain parameters as interval numbers, the interval dynamic characteristic equations and the dynamic governed equations of the structure are built by means of the interval finite element method.

基于区间模型的结构动力分析将结构中的不确定性参数用区间数来表示，建立了系统的区间动力特征方程和动力控制方程。

In this paper, interval Taylor series expansion method is proposed to solve interval differential equations and power system time domain simulation under uncertainty based on interval method is presented.
