The rigidity of concrete structure below the roof、abutment rigidity of arch foot and sunshine radiation are analyzed as factors of temperature action in roof structure. It shows that the rigidity of concrete structure has little effect on temperature action, but the rigidity of arch foot affects temperature action more and is the determinant that assures the arch mechanic behavior .The analysis result also shows sunshine radiation should not be neglected.

本文分析了下部混凝土结构刚度、拱脚支座刚度和日照温差对屋盖结构温度效应的影响，分析表明，下部混凝土结构刚度对其影响不大；温度应力较大杆件受拱脚支座刚度影响较大且拱脚刚度的大小是保证拱结构受力特性的决定因素；日照温差影响不能忽视。

5Ns. The peak position of N band emission as well as the distinct emission region slightly moves towards the open end of the cylindrical cavity, and this does not happen to O band emission. Radiation transport efficiency of 6% is obtained for the φ400×1200um cylindrical cavity heated by x-ray source with radiation temperature of 118 eV.

从时间分辨的X光强度轴向空间分布来看，在较长时间（约1～1.5ns）内，O带X光在整个观测缝对应的轴向范围之内均有较大的辐射强度，在X光强度空间分布的变化过程中，其强度峰值的空间位置基本不变；而对N带X光，则只在较短时间（约0.5ns）内，在整个观测缝对应的轴向范围之内可观测到X光辐射，但只在靠近输运源约300μm的范围内有较强发射，在柱腔末端600～700μm范围之内的辐射则很弱，N带X光辐射轴向空间分布曲线的峰值位置在朝柱腔末端的方向移动，移动量大约为130～250μm。
