A human model using polynomial convolution surface is presented which is modeled by articulated skeletons convolved with some kernel function. The convolution surface and curve correspondence theorem under orthogonal projection is presented. The human contour is approximated with a convolution curve and 3D human pose can be estimated using a nonlinear optimization algorithm.

首先建立了一种新颖的多项式密度卷积曲面人体模型，该模型由连接体线骨架与某种卷积核卷积而成，整个曲面是一张连续曲面，调节多项式和半径参数可以让人体任意变形；给出了正交投影下卷积曲面和曲线对应的概念和相关定理，为二维的图像轮廓和三维人体模型之间建立对应关系；根据正交投影下卷积曲面与曲线对应定理，用卷积曲线去逼近人体的图像轮廓曲线，从而估计和恢复出三维人体运动姿态。

Furthermore, the structures of the complexes are strange. The tripodal ligand H〓L〓 form a 2: 2 ring-like binuclear complexes [Eu〓·L〓·6DMF] ·CH〓OH·DMF with Eu〓 in DMF. Two DMF molecules are accommodated in the ring and coordinate with Eu〓.

此外配合物的结构还比较特殊，三足配体H〓L〓与铕的配合物在配位能力较强的溶剂DMF中形成环状的2：2型双核配合物[Eu〓。L〓·6DMF]·CH〓OH·DMF，环状空腔刚好能够把两个配位的DMF溶剂分子包在里面。
