提出了一种基于样条链（环）的过渡特征识别与抑制算法。该算法首先识别出模型中所有过渡特征，然后构造过渡特征面边图，依次取出其中的连通子图，建立起样条链（环），对样条链（环）依次抑制，对非样条链（环）的过渡特征按最小等半径连通子图方法抑制。研究表明，该算法能抑制变半径、等半径过渡特征且能很好地处理含有诸多样条面（非二次曲面）过渡特征的模型。

The paper proposed an algorithm of fillet recognition and suppression based on feature chain. Firstly, all fillets of the model were recognized. Secondly, a face-edge graph was built based on fillets, the connected subgraph was taken out successively, and the feature chain（ring） was established. According to the feature chain, the features （fillet） in the chain was suppressed. The fillets not in chain were suppressed by connected graph of minimal and with same radius. In summary, the algorithm can suppress the fillets with variable and constant radius, and the model containing non-quadric surface fillets can be suppressed well.
