Now, the typical pattern for an interglacial period—and we've studied several—is that the concentration of carbon dioxide and methane gas actually reaches its peak.

现在，我们已经研究过几个间冰期的典型模式，其中一种是大气中二氧化碳和甲烷含量达到峰值的情况。

But gas is becoming increasingly scarce, while coal remains abundant, so many firms are reversing the normal pattern and harvesting the gas, but ignoring the coal.

但是，天然气现在已经越来越少了，而煤炭仍然很多，于是很多公司开始改变常规的模式，他们开始收集这些气体，而忽略掉煤炭本省。

Exposure to a particular gas yields a specific pattern of colored dots, providing a chemical fingerprint.

暴露于某种气体会产生一个彩色斑点，成为化学指纹图谱。

Only if alpha were a smidgen smaller when the light passed through the gas cloud could such a pattern have been produced.

The pattern partly reflects access to gas heating, with much of northern Scotland off the gas grid.

Just as in a container, molecules in an inter-galactic gas cloud absorb certain wavelengths and leave a pattern of dark lines on a quasar's spectrum.
