For the first time, the dynamics changing process of KGM chain in vacuum is proposed, We obtained the following results: polymerization degree influences the stability and shapes of the chain, the chain stability drops with the increasing of polymerization degree, for the high polymerization degree KGM, KGM chain takes on irregular curl state; acetyl group is not the main factor influencing chain conformation , during the course of dynamics movement KGM chain takes on irregular curl state before and after acetyl group was doffed, Extending and curling states change periodicity and has good flexibility.

首次提出了KGM链的动态模型，得到了以下结果：聚合度影响其链形态和稳定性，对于高聚合度的魔芋葡甘聚糖来说，其链呈现无规卷曲状态且稳定性下降，在整个动态运动过程中KGM链脱乙酰基前后都呈现无规卷曲状态，而且其伸展和卷曲的变化是周期性的，表现出了很好的柔性，说明乙酰基不是影响其链形态的主要因素，二面角能和静电作用是真空中影响单链构象的主要的键合作用力和非键合作用力，但是乙酰基对氢键作用的影响(来源：ABC6c论文网www.abclunwen.com)较大。
