| 摘 要： | 从理论上论述了温度梯度对主镜面形变形的影响,分析了当光轴位置不同、主镜支撑方式不同时,在轴向温度梯度和径向温度梯度作用下的面形变形。通过计算,得出轴向温度梯度对面形变形的影响要远大于径向温度梯度对面形的影响,而且镜面变形不仅与主镜的线胀系数和其他材料、结构特性参数有关,与温度梯度的大小和方向均有密切的关系。

| Abstract: | The effect on the deformation of the primary mirror surface figure of the temperature gradient is discussed theoretically. And its effect under axis and radial temperature gradient is analyzed when optical axis and support ways of the mirror changed. It is concluded that the effect on the surface figure of the axis gradient is larger than radial gradient and also found that the deformation is concerned not only with thermal and structural parameter but also directly with the magnitude and direction of the temperature gradient. |
