查询词典 disks

And astronomers, in fact, have seen evidence of spiral-wave patterns in accretion disks in some binary systems.

事实上天文学家已在一些双星系统的吸积盘中，看见螺旋波图样的证据。

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。

Information leaked out that disks were stored at Wright Patterson AFB in Dayton, Ohio.

Two or more disks can be aggregated into a single virtual disk for increased capacity.

The degree of electronic angle measurement are mainly coded dial plate, grating angle measurement dial and dynamic disks in three forms.

电子测角的度盘主要有编码度盘、光栅度盘和动态测角度盘三种形式。

The wheels can be solid or comprised of a fixed stack of toothed disks, concentrically aligned, the teeth of each succeeding disk angularly offset in a common direction from the teeth of the next preceding disk to create a wheel having a plurality of uniform, elongated composite teeth around the circumference of the stack, the teeth being angled from the wheel's axis.

该轮可以是实心的或者由固定的堆叠的带齿盘片构成，它们共心地对齐，每个在后盘片的齿都与前一盘片的齿在角度上朝同一方向错开，以形成具有多个均匀、伸长的复合齿的轮，这些复合齿围绕堆叠盘片的边缘，并与轮的转轴成角度。
