According to the plane cross section assumption, configuration of a rod is expressed as a history of the cross section with arc coordinate. A special solution which stands for equilibrium in straight line state is obtained from differential equilibrium equation. Linear perturbation equation is derived and its general solution is obtained in which the integral constants are determined by constrained conditions at two ends of the rod. The condition of existence of non zero solution of the integral constants gives to the Greenhill formula of exact elastic rod model, which shows that the boundary of stable area is a closed curve and of symmetry, and inference of shearable and extensible to stability of the rod is depend on three factors: difference between flexibility of shear and extension of a section of the rod, bending stiffness and the length of the rod.

The evolution process under the control of the multigeodynamic force system (including the boundary forces of Eurasia-Pacific-Indian three massive plates around Nansha block, effects of the deep mantle, relative soft layer-sliding planes within Nansha lithosphere block and the earth's rotational inertial force) can be briefly divided four stages: the late Cretaceous to the early Eocene stage of uprilfing-erosion and shear-extension caused by the oceanwards-eastwards withdrew of Pacific subduction zone and the delamination of proto-subducted slab after the stage of pre-Cretaceous pre-rifting active continentoceanic plate margin. In this stage, the Nansha transcrustal layering-block started to move southeastwards on the Nansha transcrustal layer-sliding plane, meanwhile, the Andu-Bisheng and Liyue-Banyue basement layering-block slid on their upper-crust layer-sliding planes, and Xibu accretion zone was formed. Successively, it entered the stage of the mid-Eocene to early Oligocene, when NW-SE sea-floor spreading occurred in the southwest subbasin owing to the slip-line field initiated by the collision between the Indian and Eurasian plates, Zengmu foreland-basin started to develop in the same time. And in the stage of late Oligocene to early Miocene, near NS simple-shear extension and sea-floor spreading in the central subbasin of eastern South China Sea resulted from the south-southeastwards drawing-force of the mantle-flow. The crustal layering-blocks and the Miri accretion zone formed also in this stage.
