这些分子要比汽油燃烧得更为清洁，部分是因为他们碳-碳键较少，而且即使会释放出碳氢化合物，也不太可能会成为臭氧。

These molecules burn more cleanly than gasoline, in part because they have fewer, if any, carbon-carbon bonds and the hydrocarbons they do emit are less likely to generate ozone.

RahimRizi博士，宾放射科副教授解释说：“我们观察极化的碳- 13标记的分子，因为它可以分解并释放能量。”

Rahim Rizi, PhD, Associate Professor of Radiology at Penn, explains, "We observe the polarized carbon-13 labeled molecule as it breaks down and releases energy."
