【摘 要】从物理学角度看, 笔迹是书写工具在力的作用下在载体上形成的运动轨迹。作用力和速度的大小和变化构成了书写运动的动态特征。本文以签名笔迹为对象,研究签名笔迹的动态特征及其属性。实验结果表明:动态特征能够作为认定书写人,鉴别摹仿签名的重要依据。

【Abstract】According to physics,handwritings are some traces of writing tools on carriers under the function of forces.The dynamic features include the magnitude and variety of forces and speeds. This paper starts from the dynamic features and their attributes were researched in terms of Chinese handwritten signature. The results of experiments indicated that dynamic features were important basements which be used to identify writer, and also to distinguish imitated signatures.

【Key words】Handwriting, Signature, Dynamic feature
