薄壁的

But parenchyma cells of cotyledon did only from the later.

而子叶仅仅是距离切面400～600 μm的薄壁细胞脱分化后再分化成芽的。

This simulation shows that a capillary tube with thin wall should be used in experiment and the fringe pattern is very sensitive to the distance between the cylindrical lens and the capillary tube. For enhancing accuracy, this distance should be determined by fitting a standard liquid with known refractive index in experiment.

结果表明实验中应使用薄壁毛细管，由于干涉条纹对柱面透镜到毛细管之间的距离非常敏感，为提高精度，建议在实验中用已知折射率的标样来确定这一距离。

. Four recent papers provide comparative Information on the behaviour of torsional and distortional thin-walled and cold-formed Sections.
