不完全气体

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。

It is colourless, odorless, tasteless and it is an asphyxiant. As a poison, it is deadly at high levels.

Development of this discharge lamp waited on the invention of a material which sodium would not corrode .

高压钠灯这种气体放电灯的发明，完全依赖于一种新材料的发明，这种材料可以不让钠泄漏。

One of the noble gases, neon is colourless, odourless, tasteless, and completely unreactive.

氖是稀有气体的一种，无色、无臭、无味，完全不起化学反应。

A noble gas, it is colourless, odourless, tasteless, completely unreactive, and nontoxic.

一种稀有气体，无色、无臭、无味，完全不起化学反应，而且无毒。1868年从观察太阳周围的大气光谱中被人首度发现。

The results show that for a supersonic shear layer without reaction, a disturbance can make the shear layer become unstable, this results in one vortex or more than one vortex. The combination and seperation of vortex can intensify the mixing. But it is not easy for supersonic reacting shear layer with exotherm to become unstable with disturbance, and the effect duration is very long.

结果表明，对完全气体的超声速剪切层流动，一定的激励方式能使原先较为稳定的剪切层流动变得不稳定，产生单涡或多涡结构，发生多涡间的合并，使混合加剧；但对于存在放热现象的反应超声速剪切层流动，外加激励方式不易使流动从稳定变为不稳定，而且外加扰动的作用特征时间也较长，实际应用前景不乐观。

According to government regulation, the amount of harmful volatile organic substances indoor must be under 3 ppm. However, as we burn the paper money, the detector set at zero skyrockets to 64.4ppm, exceeding the limit by more than 20 times.

污染的情况是相当严重的，那这些燃烧都是属於不完全的燃烧，少量的出来的话，很容易就测到非常高量，几十个ppm的这些有毒气体，像是PAH之类的东西。
