However, the complexity of the minimal surface equation prevents people from modeling the minimal surface in CAD/CAGD. In this paper, based on the nonlinear programming and the FEM (finite element method), the approximation to the solution of the minimal surface equation bounded by Bézier or B-spline curves is investigated. A global method, which is called numerical extension method, is appealed to in the whole iterative process and linearize the nonlinear finite element system by using a simple iteration. Some numerical results are given in this paper. %K 极小曲面 %K Bézier曲面 %K B-样条曲面 %K 数值延拓 %K 有限元 %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=5B3AB970F71A803DEACDC0559115BFCF0A068CD97DD29835&cid=8240383F08CE46C8B05036380D75B607&jid=7735F413D429542E610B3D6AC0D5EC59&aid=6797AFC3DB48B64C&yid=D43C4A19B2EE3C0A&vid=F3583C8E78166B9E&iid=E158A972A605785F&sid=8A03DD854A27B60D&eid=C81F81170838C444&journal_id=1000-9825&journal_name=软件学报&referenced_num=10&reference_num=15
