open and close movement
Examples
- Beginning form relation of basin - mountain , the tectonic evolution and the petroleum system and pool - forming process have been studied with the integration of structural physics modeling , balance profile reversion and other new testing technology . the main innovative achievements of the dissertation can be summarized as following : 1 . on the basis of comprehensive analysis of yanqi basin relationship to tianshan orogenic belts , it was suggested that kuluketage faulted - upheaval was an aulacogen in early paleozoic , which undergone multiple opening - closing along with tianshan orogenic belts , and suffered extensively compressing in late hercyhian cycle and formed a " v - type " thrust - fold belt
论文总的指导思想是以现代石油地质理论为基础，以整体、动态、系统、综合分析为原则，以成盆?成烃?成藏研究为主线，运用正、反演相结合的残留盆地油气成藏系统评价思路，采用构造物理模拟、平衡剖面复原和多种测试新技术，从盆山耦合关系切入，研究含油气系统成藏要素及其相互作用过程，探讨油气成藏主控因素和油气分布的有序性，取得如下创新性成果和认识： 1 、系统分析了焉耆盆地形成演化与天山构造带的关系，提出盆地南侧的库鲁克塔断隆在早古生代为一大型裂陷槽，之后随着天山构造带的演化，经历了多次开合运动。 - In the design , gear and spline were adopted , so symmetrical movement of ( collimator ’ s ) lead gates can be achieved easily , mechanical structure became more compact . worm was adopted to adjust mirrors accurately , and deflection of mirrors can be prevented in case of the external impacts or vibrations
采用齿轮齿条结构,实现铅门的对称开合运动,使子系统的机械结构更为紧凑,同时提高了定位精度;采用蜗轮蜗杆调解反光镜的角度,可以使反光镜的调节更精确,同时可以防止在外界振动或撞击下反光镜发生偏转。
