The centerline of elastic rod or elastic filament can be abstracted as space curves to deal with them by the knowledge of the theory of space curve and differential geometry.
由于弹性杆的中心线或弹性细丝可以抽象成空间曲线，然后根据空间曲线论和微分几何的知识进行处理。
As the laser tube can be cooled both on the inner - and outer - surfaces of the tube, the thermal effect in SSTL is smaller than that in a rod laser with the same geometry size.
与同样尺寸的棒状激光器相比，由于它可以通过管内外壁冷却激活介质，因此其热效应较小。
