Acetylene is a simple asphyxiant and anesthetic.

乙炔是简单的窒息物和麻醉剂。

Nitrogen is a simple asphyxiant and considered nontoxic.

氮仅仅是窒息剂，认为是无毒的。

Simple Asphyxiant - This product does not contain oxygen and may cause asphyxia if released in a confined area.

单纯窒息剂----该产品不含氧，因此如果在相对封闭的空间中发生泄漏可能引起窒息。

The oxygen consumption rate(OCR) and the effect of body weight on the asphyxiant point(AP) of Hemibarbus maculatus Bleeker were studied.

实验测定了花的耗氧率和窒息点，并对耗氧率的昼夜变化规律以及体重对其窒息点的影响进行了研究。

Under the same water temperature, the oxygen consumption rate and the asphyxiant point decreased as the body weight of the crayfish increased.

在大小相近的个体中，单位体重的耗氧率和窒息点随温度的升高而增加。

Simple Asphyxiant - This product does not contain oxygen and may cause asphyxia if released in a confined area. Maintain oxygen levels above 19.5%. Flammable.

易窒息性气体-这种产品由于不含氧气，因此在狭窄的空间发生泄漏，可能会使人窒息。应保持氧含量在19。

Acetylene is a simple asphyxiant and anesthetic. Experiments have shown there to be no harmful effects from chronic exposure to acetylene at high concentrations.

乙炔是简单的窒息物和麻醉剂。实验显示慢性接触高浓度乙炔没有有害影响。

Although nitrogen is nontoxic and largely inert, it can act as a simple asphyxiant by displacing the oxygen in air to levels below that required to support life.

尽管氮无毒且很大程度上不活泼，通过取代空气中的氧，使之下降到维持生命所必须的水平以下它可以为简单的窒息物。

Simple Asphyxiant - This product does not contain oxygen and may cause asphyxia if released in a confined area. Maintain oxygen levels above 19.5%. Nonflammable.

单纯窒息剂——该产品不含氧，因此如果在相对封闭的空间中发生泄漏可能引起窒息。应确保氧含量高于19。
