carbon dioxide cycle

基本解释

When animals die, they return to minerals and carbon dioxide and the cycle renews.
当动物死时，他们又回归成矿物质和二氧化碳，进入新的循环。
The theoretical analysis and simulation validation showed that for transcritical carbon dioxide cycle there exists an optimal pressure.
理论分析并模拟验证了二氧化碳跨临界循环存在最优压力这一结论。
We all know that trees can be recycled carbon dioxide, with a large number of felled trees, the number of trees will be drastically reduced, we can not be exhaled carbon dioxide cycle.
大家都知道树木可以循环二氧化碳，如果大量砍伐树木，树木的数量就会急剧减少，我们呼出的二氧化碳无法得到循环。

Carbon dioxide pumped into carbon cycle, is not.
