And the coil diameter

Based on this, the interrelations between the elastic coefficient and the structural parameters of the nanospring, such as tube diameter, spring diameter and coil pitch, are carefully studied.

在此基础上，分析了单层碳纳米弹簧的弹性常数与弹簧结构参数（如管直径、弹簧直径、簧圈节距等）间的关系；

This method is ensured to calculate the tensile stress in the recoiling process under the variable coil diameter and speed conditions.

这种方法计算的卷机功率可在卷径、卷取速度变化的工况下，保证卷取过程中的张力。

The two helical nanofibers have absolutely opposite helical senses, but have identical cycle number, coil diameter, coil length, coil pitch, fiber diameter, and fiber cross section.

它们具有绝对相反的螺旋旋向，但却具有相同的纤维直径，纤维截面，螺旋直径，螺旋圈数，螺旋间距，和螺旋长度。
