In the device, a four-post frame was adopted, two synchronously rotating grip holders were used to realize rigidity rotation of the specimen, and the axial movement of the upper grip holder implemented the tension/compression loading. Positioning accuracy in the axis, radial and circumferential directions were achieved by adopting many advanced and delicate technologies. Measurement on the device indicated that the actual positioning accuracy of the device was better than the kinematic positioning accuracy. Evaluation test on the system indicated that the spatial resolution is better than the pixel size without considering the noise.

该装置采用了四柱式框架结构，采用上下夹头同步转动实现试件相对于框架的刚性转动；上夹头作相对于框架的轴向运动实现对试件的加载；在加载和转动装置中采用了诸多高精技术，实现了试件高精度的轴向定位、径向定位和刚性角度定位；对装置的精度检测表明其实际的定位精度优于运动学定位精度要求；对系统的计量考评初步表明，系统不计噪声的空间分辨率优于X射线CCD的像素10.9μm。

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。
