According to field trials, measurement results of FBG straintube are mostly agreeable with these of declinometer.
现场实验结果显示FBG应变管的测量结果与测斜仪的测量结果非常吻合。

But each strain is slightly different, and only the fastest growing one - determined by which tube turns the darkest green - will be chosen for further development.
但是每个品种略有差异，只有生长最快的那个——管子里颜色变得最绿——会被选择进一步开发。

And the strain sensitivity coefficients are studied in detail when sticking the mental tube packaged FBG sensors on two materials.
