Second, we study the behavior of the solutions of the minimal surface equation at the origin and at the infinite by using the blow up and the sip in process. Finally, we claim that the solution is linear on the boundary and conclude that it is a plane.Contents試委員會審定書 ibstract in Chinese iibstract in English iii Introduction 1 The Necessary and Sufficient Conditions for the Existence of a Linear Solution 3 The Behavior of u at the Origin and the Infinity. 4 The Behavior of u on the Boundary 7 u is linear 11eferences 12application/pdf213023 bytesapplication/pdfen-US最小曲面無界域扇形域邊界接觸角偏微分方程minimal surfaceunbound domainsector domaincapillary boundary conditionPDEthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/180580/1/ntu-97-R95221006-1.pdf
