此发现证实了一个天文学家小组先前获得的观察:银河系有两条主要的螺旋臂,是一个普通中心带有横条的星系结构。
The findings confirm an earlier observation by a team of astronomers , making a strong case that the Milky Way has two major spiral arms , a common structure for galaxies with bars .

在古老银河系的螺旋状西臂末端,任何地图都还没标示过的蛮荒地带,有个丝毫不引人注目的小小黄色恒星。
Far out in the uncharted backwaters of the unfashionable end of the western spiral arm of the Galaxy lies a small unregarded yellow sun .

在化学波的研究上,BZ反应也展现了多姿多彩的斑图,如靶形波、螺旋波、多臂螺旋波等。
In the investigation of chemical waves , BZ reaction exhibits versatile spatiotemporal patterns , such as target wave , spiral , spirals of multiple arms .

研究了局域动力学为混合模式振荡的螺旋波动力学,发现了螺旋波的波臂分叉现象,这是第一次在螺旋波波臂内部发现复杂次级结构的存在。
The spiral waves with mixed-mode oscillatory local dynamics are first studied using the coupling allosteric reaction-diffusion system , which gives rise to the observation of the arm-splitting phenomenon of the spiral waves . It is the first time to discover the complex sub-structure within the spiral arm .
