局域相空间--由混沌形成？
Local Phase Space - Shaped by Chaos?
摘要：
我们试图了解当地的相空间的状态，通过比较模拟的2-D速度分布的分布，构造为太阳附近，从恒星的径向和横向速度的测量。为了产生成功的局部相空间模型，必须考虑银河系中心棒和螺旋斑图的联合扰动。混沌的存在被认为是形成所观察到的相空间结构的一个重要成分。
英文摘要：
We attempt to understand the state of the local phase space by comparing simulated 2-D velocity distributions to the distribution that is constructed for the solar neighbourhood, from measurements of stellar radial and transverse velocities. The joint perurbation of the central bar in the Galaxy and the spiral pattern is found to be a must, in order to produce successful models of the local phase space. The existence of chaos is found to be an important ingredient in the formation of the observed phase space structure.
