In the core of the larger spiral structure of NGC 1300, the nucleus shows its own extraordinary and distinct "grand-design" spiral structure that is about 3,300 light-years long. Only galaxies with large-scale bars appear to have these grand-design inner disks — a spiral within a spiral. Models suggest that the gas in a bar can be funneled inwards, and then spiral into the center through the grand-design disk, where it can potentially fuel a central black holes. NGC 1300 is not known to have an active nucleus, however, indicating either that there is no black hole, or that it is not accreting matter.
星系演化除了像两个星系相撞那样的剧烈作用之外,还有自己内部很慢的演化,因为一个星系总会有一些引力不稳定,如上图中的NGC1300,它是一个棒旋星系,这种bar结构导致的引力不完全对称会驱使很多气体和尘埃损失角动量往里面落,我们可以清楚的看到dust lanes,有点像黑洞的吸积,但这个星系是个非活动星系,目前还没有黑洞存在的明确证据,but我相信肯定是有的,没有比在星系中心放一个黑洞再完美不过的事情了,或许这些下落的dust lanes是黑洞发光的开始呢。

And use the prior and more consummate ways to carry through vaneaccidence design, These ways have own technology points and disadvantage, In this paperstressly discuss the momentum-element theory way, this way was developed in the basic ofthe two ahead ways, and it overcome their defect. It also use element theory to deal withvane design. In the vane designing and aerodynamical characteristic calculating they bothrelate with intervene gene, so the keystone is to carry through the intervene gene in twocase, thereout to do the vane design and aerodynamical characteristic calculating.
