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.

The results are shown as below.1 Tectono-thermal evolution: The history of the Songliao basin is divides into four stages, high-temperature doming and extension, high-temperature rifting, low-temperature depression, and low-temperature shrinkage. Numerical simulation of mechanical process shows that the basin appeared in the early- to late- Jurassic as a result of rapid low-angle subduction of the Pacific plate towards the northwest, of movement of the Siberian block towards the southeast, of many other influences such as internal thermal stress in the mantle, gravitational force, stress of phase transition, etc. Both the Pacific plate and the Siberian block slowed down in the early Cretaceous, and almost stopped in the middle Cretaceous with the rapid decrease of abnormal heat in the mantle below.
盆地构造热演化力源机制数值模拟研究表明：早、中侏罗世至晚侏罗世晚期，盆地演化主要是太平洋块体向北西方向以低角度快速俯冲和西伯利亚块体向东南俯冲共同作用的结果，同时也与地幔内部热力、重力、相变力以及地球自转及公转速度变化效应和上覆块体绝对运动的作用有关；早白垩世早期至早白垩世中期，来自东部太平洋块体俯冲作用的减弱，而这一时期影响盆地演化的主要力源是地幔内部热力、重力、相变力以及地球自转及公转速度变化效应和来自西伯利亚块体俯冲作用；进入早白垩世晚期至晚白垩世早期，由于双重俯冲带中西侧俯冲作用带基本停止活动，而本区地幔热能的快速衰减则控制盆地的构造热演化；晚白垩世晚期以后，太平洋块体活动加强和地幔热运动是影响盆地演化的主要动力。

Autogiro：自转旋翼机
自转旋翼机(autogiro)是依靠无自身动力驱动、可自由旋转的旋翼提供升力飞行的飞行器(如图1). 飞行中,旋翼本身无发动机驱动而是靠空气作用力驱动其自转,进而产生升力. 旋翼仅在起动时有自身动力驱动,之后靠空气作用力驱动.
