Hypoxic-ischemic encephalopathy experimental grouping: Sixteen successful C57/BL6J mice models, aged 7 days, were randomized into 2 groups: experimental group (n =8), following ligation of right common carotid artery, mice were placed in the closed container containing 0.08 volume fraction of oxygen and 0.92 volume fraction of Nitrogen gas, and taken out 1.5 hours later; 3 μL ESCs were injected into the right cerebral ventricle at about 1 week, and control group (n =8), in which, the same amount of PBS was injected into the right cerebral ventricle.③ At 12 weeks after transplantation, the survival and migration of induced ESCs labeled by Lac-Z in the spinal cord and brain were observed by zymologic method.

缺氧缺血性脑病实验分组：将造模成功的鼠龄7 d的C57/BL6J16只小鼠随机分为2组：实验组8只，结扎右侧颈总动脉后将小鼠置入含体积分数0.08氧气和体积分数0.92氮气的密闭容器内，1.5 h后取出；1周后在右侧脑室内注入3 μL诱导胚胎干细胞。

Skelton highlights the water vapour and oxygen transmission rates, its unsuitability for carbonates and the fact that it deforms at high temperatures.

skelton突出了水蒸汽和氧气的传输速率，它不适合为碳酸盐岩和事实，即它变形在高温下。

That's the Earth now," Alex says, pointing to a dark shape at the bottom."And then it's just starting to fade away." Looking up to make sure his mother is following along, he taps the end of the drawing:"In 20 years, there's no oxygen." Then, to dramatise the point, he collapses,"dead, to the floor.

Alex指着图下方的阴影说，&这是现在的地球，现在它正在慢慢消失&，然后他抬头看看她妈妈有没有跟上了他的讲话，接着指着画作的另一端说，&再过20年，地球将没有氧气&，最后，他倒在地上，生动展现地球的&死亡&。

Two of these pump blood to the lungs, where it picks up oxygen, then the other two pump this oxygenated blood throughout the body. One of these four chambers—the left ventricle—contracts most strongly to pressurise the blood.

相比之下，人的心脏只有四个心室，其中的两个心室收缩将血液压进动脉输送到肺部，在那里吸收氧气，放出二氧化碳，而另两个心室则将完成气体交换后的血液输送到到全身。

Because designers could not burn all oxygen (about 20%) out of the air in regular turbojet combustion chambers, since the existing material could not be used to make turbines which could stand such high temperatures.

因为设计师不能燃烧所有的空气中的氧气(20%)，用常规的涡轮喷气燃烧室，因为现有材料不能用于制造能承受如此高温的涡轮。

Now oxygen does not boil away from liquid air so easily as nitrogen. By careful arrangement

现在氧气那么容易地不从液态空气煮沸作为氮气。
