螺旋臂

最后利用仿真验证了激光刻蚀螺旋臂实现正交馈电的可行性。

Finally , the simulation showed the feasibility of laser etching spiral arms for orthogonal feed . 3 .

这当然是在星系中的大质量恒星诞生区，而且它们通常分布在蓝色的星系螺旋臂上。

Near their massive star forming regions , of course , and those regions tend to lie along sweeping blue spiral arms .

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 .

有螺旋形构造的星系；包括年纪较小的恒星在中心从年纪较大的中螺旋出去的臂状物。

A galaxy having a spiral structure ; arms containing younger stars spiral out from old stars at the center .
