Lumped models of skeletal muscle have been assumed a) in the design of experiments and the interpretation of experimental findings, b) in theoretical studies. In this paper, a population model that takes into account the differing properties and separate (independent) activation of motor units is presented as the most appropriate for muscle. A realistic (for muscle) transformation, population leads to lumped model, resulting in the lumping of motor unit neural signals or system responses, is proposed. On this basis, the possibility of modelling muscle as a single system is examined; and the consequences of treating muscle as a lumped system, in experiments or theoretical studies, are discussed. Also, the advantages of lumping, in models of muscle, are reviewed. Predictions of a computer population model, together with actual recordings from a hand muscle, are used to confirm the results of the analysis.
a) 实验设计及实验结果解释；b) 理论研究。本文提出一种考虑运动单位不同特性及独立激活的群体模型，认为它最适合用于肌肉研究。提出一种符合实际（针对肌肉）的转换方法，从群体模型导出集总模型，从而实现运动单位神经信号或系统响应的集总。在此基础上，研究了将肌肉建模为单一系统的可能性；并讨论了在实验或理论研究中将肌肉视为集总系统的后果。此外，还回顾了肌肉模型中集总的优点。利用计算机群体模型的预测结果以及手部肌肉的实际记录来证实分析结果。
