为了适应内饰线采用无支架宽板链形式作业要求，确定橇体长度为4800mm ，比车身长度短。

We made an experimentally and theoretically research on SRS at low temperature (about 80K-190K) in highly single mode circular optical fiber. The experimental apparatus is designed and the principle of experiment is given. The SRS in highly single mode circular optical fiber is measured at different temperature. A series of SRS spectra is get in low temperature. On base of the spectra, we get a curve of the frequency shift and the half breadth with the temperature fluctuation.
