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。

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.

实践中，各地对不动产登记的收费方式和标准差异很大，并且存在收费过高的现象，比如就房屋所有权登记而言，有按房屋建筑面积的比例计收，也有按房屋价款的比例计收；即使是不动产登记费按件计收的地区，收费标准也高低不一。
