摘要:自旋是微观客体的固有属性。微观客体是“限制在一定分布空间的转动场物质球”，转动频率由 定义，曲率半径由 定义，存在于双4维复数空间。微观客体的旋转与运动生成物质波。物质波传播微观客体空间结构及物质场宻度分布的波动信息。复数时空曲率坐标的建立，是微观客体自身物质的几何化。物质波是实在的，物质场宻度分布与概率分布可以相互映射，微观客体的非点特性及其旋转振动是量子测量中微观客体概率事件的物理源头。

Abstract:Spin is the inherent attribute of the micro-object. Micro-object can be understood as a rotating matter ball which is limited in a certain spatial distribution that can not be appropriately abstracted as a particle in the mi-cro-environment. The rotation frequency is defined by , radius of curvature is defined by . Mi-cro-object exists in the dual 4-dimensional complex space-time. The rotation and movement of the micro-object gener-ate matter waves. Information of space structure and matter field density distribution of the micro-object can be propa-gated by matter waves. The establishment of complex space-time curvature coordinate is a geometric matter of mi-cro-object itself (geometry of matter). Matter waves are real. Matter field density distribution and probability distribu-tion of micro-object can be mutual mapped, micro-object can not be appropriately abstracted as a particle and its rotat-ing and vibration are the physical source of micro-object probability event in quantum measurement.
