氧气

Through the theoretical analysis of the diffusion coefficient of oxygen in crashed coal, its calculation formula was obtained .

根据松散介质中气体扩散的理论分析，得出了松散煤体中氧气等效扩散系数的理论计算公式。

Take 60 mg twice a day of Coenzyme Q10 (CoQ 10), which can improve use of oxygen at the cellular level.

每两天服用60毫克的辅酶Q10，它能够能够在细胞层面改善氧气的使用情况。

Iron also serves as a cofactor of several essential enzymes.

所以铁是供应氧气到细胞的主要因素。

In the lab, the yellow colorant turns into green when mixed with oxygen in the air!

我们从植物中提取染色剂染衣服，在实验室里，像魔法一样，黄色的染色剂在空气中与氧气结合变成了绿色！

I mean, they feed off of oxygen and combustibles.

氧气和易燃物是起火的基本因素

Our first explosion used up the available oxygen in the combustion chamber and it needs to be refreshed.

我们的第一次爆炸中使用了燃烧室提供氧气，它需要被刷新。

Oxygen and fuel gas can be imput from left or right to center gas pathway,through the caliber condign pathway transfer to cutting torch.For effectively working of the many torches' cutting machine,the center gas supply system using solenoid control the gas flow connecting or breaking off,and through regulator adjusting gas pressure.

氧气或燃气可以从左边或右边输入中央气路，通过口径适宜的管路传送到割炬，为了使多割炬的切割机有效地工作，中央配气系统使用电磁阀控制气流的通断，并通过压力调节器调节气流的压力。

All those factors lead to an increase of oxygen consumption but at the same time contribute to the constriction of vessels.

所有这些因素导致氧气消耗的增加，但同时供给血管收缩。

IT IS FOR THIS REASON THAT CUTTING OFF THE AVAILABLE SUPPLY OF OXYGEN IS CONSIDERED TO BE THE BEST METHOD OF EXTINGUISHING AN OIL FIRE BY COVERING THE SURFACE WITH FOAM.

因此，使用泡沫覆盖油火表面以隔绝氧气供应是扑熄油火的最佳方法。

The limit oxygen concentration and the limit gas velocity are critical index to evaluate the flammability of materials.

极限氧气浓度和极限气流速度两个极限参数，是衡量材料可燃性的关键指标。

Do you know, i need you to come back

你知道吗，我需要你回来
