Spiral Growth Structure and Its Mechanism of Nacreous Layer of Pteria Penguin and Blister Pearl From Sanya, Hainan Province
-
摘要: 采用干涉显微镜、环境扫描电子显微镜、原子力显微镜对海南三亚企鹅贝及其附壳珍珠的珍珠层表面微形貌进行了研究。通过对该珍珠层的表征与示踪,初步证实微尺度螺旋(涡旋)生长位错是海南三亚企鹅贝及其附壳珍珠又一重要的生长机制。并指出,这种螺旋生长机制与中国南海某种生态动力学机制有关。对珍珠层生长结构的研究现状与发展趋势予以了综述和讨论。Abstract: Surface microtopography,representation and tracing of nacreous layers of Pteria penguin and blister pearl from Sanya, Hainan Province, are studied by using interference microscopeand environmental scanning electron microscope and atomic force microscope. The research indicates that the microscale spiral (vortex) growth dislocation is another important growth mechanism of Pteria penguin and blister pearl from Sanya, Hainan Province. It indicates that the microscale spiral (vortex) growth dislocation is related to the ecosystem dynamics from South China Sea. The research present situation and advancement of growth structure of nacreous layer are discussed.
