The main aim of this paper is to study the superconvergence accuracy analysis of the famous ACM＇s nonconforming finite element for biharmonic equation under anisotropic meshes. By using some novel approaches and techniques, the optimal anisotropic interpolation error and consistency error estimates are obtained. The global error is of order O（h^2）. Lastly, some numerical tests are presented to verify the theoretical analysis.

Isometric 3D shape partial matching has attracted a great amount of interest, with a plethora of applicationsranging from shape recognition to texture mapping. In this paper, we propose a novel isometric 3D shape partial matchingalgorithm using the geodesic disk Laplace spectrum （GD-DNA）. It transforms the partial matching problem into the geodesicdisk matching problem. Firstly, the largest enclosed geodesic disk extracted from the partial shape is matched with geodesicdisks from the full shape by the Laplace spectrum of the geodesic disk. Secondly, Generalized Multi-Dimensional Scalingalgorithm （GMDS） and Euclidean embedding are conducted to establish final point correspondences between the partialand the full shape using the matched geodesic disk pair. The proposed GD-DNA is discriminative for matching geodesicdisks, and it can well solve the anchor point selection problem in challenging partial shape matching tasks. Experimentalresults on the Shape Retrieval Contest 2016 （SHREC＇16） benchmark validate the proposed method, and comparisons withisometric partial matching algorithms in the literature show that our method has a higher precision.
