二氧化碳

In fact, the energy used to keep display clocks lit and memory chips working accounts for 5 percent of total domestic energy consumption and spews 18 million tons of carbon into the atmosphere every year!

事实上，能源用在显示警示灯及运作记忆芯片上约占了总家庭能源消耗的百分之五，也因此每年有一百八十亿吨的二氧化碳被排放到空气中！

Psig, is very cold and sublimes so quickly that prolonged contact with the skin causes freeze burn or frostbite.

压力在61 psig以下的二氧化碳固体温度极低，升华得非常快，持续接触皮肤会导致冻伤。

Carbon dioxide, solid below 61 psig, is very cold and sublimes so quickly that prolonged contact with the skin causes freeze burn or frostbite.

压力在61 psig以下的二氧化碳固体温度极低，升华得非常快，持续接触皮肤会导致冻伤。

The use of sulfates and carbon dioxide requires strictly anaerobic conditions.

It contains constituents of chlorides, phosphates, sulfates, and carbonates, as well as organic components of proteins, digestive enzymes, and carbon dioxide.

它包括的组分有氯化物，磷酸盐，硫酸盐和碳酸盐。同时也包括了许多有机组分，如蛋白质，促进消化的酶以及二氧化碳。

As we all know,in the sewage there contains a great deal of poisonous gas ,such as CO,CO2,methane and sulfureted hydrogen etc.

人们都知道，排污管道中含有大量的臭素、二氧化碳、甲烷、硫化氢等有害气体。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.
