Now we want to show what our active link will look like. To do so use your rectangle marquee tool again to make a selection similar to the following

第七步：现在我们想要我们的活动链接看起来像这样，所以再次使用你的矩形功能创建一个选区，像下面的那样。

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。

Seidel aberration sums of such a system were derived based on the addition theorem.

由初级像差加和定理推导了适合于这种系统的赛德尔和数公式，并指出了寻找消赛德尔像差的平板透镜系统的方法。

Before the Horde itself we fell like addled children, like old men, like wheat.

在部落面前，我们就像一个头脑混乱的孩子，像一个老人，如同麦子一般。

The so-called "adiabatic expansion" means that the light generated by the acoustic signal in the absorption within the region transit time under the same conditions are far greater than the time required for thermal diffusion, negligible effect of the proliferation of light signal the impact of this Conditions, acoustic imaging to short-pulse laser for excitation, ultrasonic signal for the information to the carrier, with high-resolution and high-contrast imaging features.

所谓的"绝热膨胀"是指所产生的光声信号在吸收区域内的渡越时间远远大于相同条件下热扩散所需的时间，可忽略热扩散效应对光声信号产生的影响，在此条件下，光声成像以短脉冲激光为激励源、以超声信号为信息的载体，具备高分辨率和高对比度的成像特点。

Based on two-dimensional elastic wave equation and adopts the well logs as constraint condition, a new imaging method of crosswell seismic data-elastic wave equation inversion and imaging with the well logs constraint is given by using adjoint theory of distribution-parameter control system.

基于二维弹性波动方程，利用分布参数控制系统的伴随理论，采用测井资料作为约束条件，本文给出了一种井间地震资料速度成像的新方法——井间测井约束弹性波动方程反演成像。

In step 5, the reason you could only see the afterimage in the uncovered eye is because it occurs at the point of input and not the point of process.

在步骤五中，之所以只有被遮住的那只眼睛可以看到后像，是因为后像是在输入位置而非处理位置产生。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".
