But some molecules hold most of their negatively-charged electrons closer to one side, lending them a lopsidedness that can jiggle back and forth to absorb the energy of incoming infrared rays.

但是有些分子将其部分带负电的电子放在靠近一侧的地方，使它们具有一倾斜性，可以来回抖动以吸收进入的红外线的能量。

And it turns out that both carbon dioxide and methane spend most of their time " shaking it" in electrically-lopsided ways, allowing them to absorb infrared rays and help insulate the earth.

事实证明，二氧化碳和部分时间都在以电不平衡的方式 “摇晃”，使它们能够吸收红外线并帮助地球绝缘。
