利用检测单模双折射光纤弯曲传输损耗装置测绘了光纤的弯曲损耗图及光纤弯曲传输模式图。

Using the instrument for the transmission loss of single mode of winding birefringence optical fiber, the spectrogram of loss and the graph of mode density are obtained.

针对这些不利因素，对生产装置上常遇到的比较难测绘的几种零件，如弹簧、叶轮、齿轮，用多种计算的方法对测绘数据进行处理，以得到完整的零件工作图。

Aiming these factors, we use different calculating methods to handle the surveyed data. Such as that of spring, turbo wheel and gear in order to get the complete work drawing of the spares.
