可见，小麦氮素含量和氮素利用效率的遗传模型在不同的水氮环境中不完全一样。
It is thus evident that the genetic models of nitrogen concentrations and nitrogen utilization efficiency of wheat in different water and nitrogen environments were different.
我只是数百农民中的一个，试着少用些氮，我想环境变好，我们就喝这里的水，我们想任何东西都安全。
"I'm just one of hundreds of farmers doing this, trying to use less nitrogen," he says. "I want the environment to be good, too."
由此产生的冷冰的气态氮被注入发动机汽缸（见图）。与此同时，乙二醇与水的混合物也注入其中，这种混合物是一种常温环境下的“传热液体”。
The resultant cold, gaseous nitrogen is now injected into the engine's cylinder (see diagram) along with a mixture of water and glycol, known as a heat-transfer liquid, that is at room temperature.
