In this paper, a region approximation idea that means using a "fat curve" with a width to approximate the offset curve is proposed, and a complete set of algorithms to approximate offset curve using disk Bézier curve are given and implemented. In the algorithms, the optimal and uniform approximate curve of the offset curve as the central curve of the Disk Bézier curve is found by using Remez method, and then the upper optimal and uniform approximation principle is proposed to compute the error radius function of the Disk Bézier curve. Thus, the whole Disk Bézier curve can be obtained. In the end of this paper, the approximate effect of the Disk Bézier curve is not only analyzed and assessed, but also some specific examples are provided.

提出用一条带宽度的"胖曲线"来逼近上述等距曲线的区域逼近思想，并建立与实现了圆域Bézier曲线等距逼近的整套算法，包括应用Remez方法求出等距曲线的最佳一致逼近曲线作为圆域Bézier曲线的中心曲线，提出上控最佳一致逼近的原理求出圆域Bézier曲线的误差半径函数，以及确定整条圆域Bézier曲线，最后还对该圆域Bézier逼近的效果做了分析和考核，并给出了一些具体实例。

Most studies on fire prevention focus on buildings themselves, such as fire protection facilities, the usage of uninflammable materials, the design of partitions for preventing from fire hazard, etc. However, few researches discuss how to manage fire hazard in community scale concerning surrounding environments, space structure, land use, etc. Recently, urban plans are requested to take hazard mitigation into account. It demands more studies on the urban scale. Hence, this research proposes an evaluation method to assess fire risk degree in terms of urban blocks.

然而，目前一般消防单位对於消防安全之检视大多仅著眼於建筑物内部的消防设备或是建物内部防火设计是否妥当等硬体面，但从都市整体角度，即周边环境、空间结构以及建物、土地使用等因素对於火灾之影响则甚少探讨之，再加上都市防灾计画与检讨中亦须风险的资讯，因此本研究拟就都市街廓尺度，评估其火灾风险度，以作为都市地区消防规划、通盘检讨以及都市更新等政策决定之参考依据。

The equivalence, performance bounds, existence, uniqueness and necessary condition of ME control are studied to show the ME method to be reasonable, applicable and effective.

ME方法是一种全局分析法，它不仅包含了MSE和MAP准则，且由于全文在整个推导中并未假定高斯性、线性和非时变等，因而原则上适用于诸如非高斯、非线性、时变等传统方法难以处理的复杂系统；不仅适用于工程系统，将其推广到决策、社会、经济等领域会更为自然和切合实际。

The special geometric restrictions like parallelism andperpendicularity implicated in vanishing elements are deeply studied. In single-view case,the theory is presented to interpret relationship between two planar lines by applying 3Dinvariants of vanishing points. In two-view case, the method on extraction vanishing pointof an arbitrary spatial line is described, and moreover, the theory is presented to interpretrelationship between two elements in 3D space, such as two lines, two planes, line andplane, and so on.
