The X-ray imaging observation and the localized velocity structure favor such a bound-incoming model that these two clusters, with a true spatial separation of about 6.4Mpc/h, are moving together with a relative velocity of 664 km/s along the direction with a projection angle of 71.5 du.
近来的X-ray成像观测以及局域速度结构支持这样一种束缚塌缩模型：两星系团的真实空间距离约为6.4Mpc/h，其投影角为71.5度，并正以大约664千米每秒的相对速度靠近。

In the surveys, some very closely spaced survey lines displayed remarkable differences in crustal structure. To find the reasons for the differences and to analyze the reliability of crustal structure, ocean bottom seismometer data from the west and east sides of the Dongsha Islands were reprocessed and inverted with tomography technique. The routine processing and inversion procedures include clock correction, position correction, finite-difference ray-tracing-based tomography, checkerboard test and comparison of the inverted crustal model with initial models. As a key step, we analyzed the lateral velocity resolution and smoothed out the short wavelength velocity variation which maybe most probably artifacts in the final velocity models.
在一些相隔很近的测线上，探测的深部地壳结构却相差较大，为了分析这些探测结果中差异的原因和地壳结构变化的可靠性，本文以东沙东侧海域测线和东沙西侧海域测线为例，对采集的海底地震仪记录进行了时间、位置校正和初至波走时拾取，利用有限差分地震走时层析成像进行了走时反演，获得所在剖面的地壳速度结构，并分析了模型的横向分辨率，剔除模型中短波长的横向速度变化。

It consists of fitting seismic ray traveltimes and positions to data calculated by ray tracing. In order to improve inversion stability and efficiency, seismic ray is described by Hamilton function and ray tracing is done in phase space. Validation tests on synthetic and practical data are analyzed. The tests show that this tomographic method is effective for estimating velocity field in complex media.
为提高反演的稳定性和计算效率，引入了Hamilton函数描述射线，在相空间计算反演所需的射线路径和目标函数对模型参数的导数，对理论模型和实际地震资料进行了试算，试算表明该方法对复杂介质具有较强的适应能力。

真空的折射率可以>介质中的折射率!例如:真空折射率就>玻璃折射率!这样的话,明白人会看出,X-ray在玻璃中的传播速度会>光速!不错,这里指的速度是"相速度"(phase velocity). 但是,光的"群速度"(group velocity)是不会超过光速的!
