基于不同的物理假设，建立或采用了六种可能的模型来描述单个微纤丝的弹性模量值，即与微纤丝像松散或懒惰弹簧一样缠绕在一起的胞轴的弹性模量值。对严格模型和简化模型之间的差异进行了彻底的评估。模拟结果表明，简化模型与严格模型有很大差别，特别是在微纤丝角较小的范围内。这将解释在先前的模型研究中看到的在低微原纤角时对细胞壁硬度的较差估计。
Based on different physical assumptions six possible models are developed or adopted concerning the component of the elastic modulus of a single microfibril, i.e. the elastic modulus that is parallel to cell axis about which the microfibril is coiled like a loose or lazy spring. A thorough evaluation regarding the disparities between the rigorous and simplified models is presented. The simulation demonstrates that the simplified models differ considerably from the rigorous one especially in the small microfibril angle range. This would explain the poor estimations of cell wall stiffness at low microfibril angles as seen in previous modelling studies.
