As nonlinear factor of displacement is not taken into account in design of thermal overhead pipeline previously, actual stress condition of pipeline and support can't be reacted correctly.

原先热力架空管道的计算没有考虑到位移的非线性因素，不能正确地反映管道和支座的实际受力情况，现结合热力架空管道和支座的受力情况，给出了力学的计算模型。

Then, thermal design was concentrated on the sun-oriented work pattern in low-temperature condition primarily.

然后，以对日低温工况热设计为主对遥感器进行了热设计。
