一次

Maddox pointed out in an interview that it was an asteroid hitting Earth 64 million years ago that killed off the dinosaurs and many species of life.

马多克斯在一次访谈中提到，正是6400万年前的一次小行星撞击地球，灭绝了恐龙和许多其他生物物种。

I watched its whole magnificence for the last time as if it were the first.

我最后一次欣的景色就好像我是第一次看一。

Again and again, on every public speaking occasion, before crowds of thousands, he would repeat this sentence and declare openly and publicly: 'I am the son of a Chinese mainlander, and I advocate Taiwan Independence.

一次又一次，在每一个公开演讲场合，在万千群众面前，他总是以这句话当开场白：「我是一个外省囝仔，我主张台湾独立。

He has to start the car. He has to make a right turn, a left turn, and a U-turn.

他得发动汽车，然后左转一次，再右转一次，还得转个U形弯。

Every takeoff is optional. Every landing is mandatary.

每一次起飞都可有可无，每一次着陆却非要不可。

But I did many a time, through all these years.

我见过，一次。这么多年来，就一次。

You will want to return to it many, many times.

你将会一次又一次的去回顾它的。

This is the last time, Marshall.

最后一次，马歇尔听清楚了，最后一次！

In every group, rabbits were subdivided into experimental and control subgroups. 2 Rabbits were bullets injected followed by continuous injected with 13C labeled leucine, glucose, and lactic acid; 3 Blood were drewed before and 150, 160, 170, and 180 min after the initiation of isotopes injection for material analysis; 4 Exhale gas were collected every 5 min in the first 30 min followed by every 30 min there after for material analysis; 5 After centrifuge in low temp the supernatant of the blood samples were collected and went through axon and anon exchange column treatment; 6 Treated blood sample was used for 13C labeled leucine, glucose lactic acid examination through mass spectrograph; 7 The exhale gas was collected for 13CO2 exam through gas-phase mass spectrograph; 8 CO2 total production rate (V13CO2), body various substances production, oxidation speed, and substances metabolic percentage all can be calculated through equations provided by references below; 9 Data was processed through student t test.

分亮氨酸、葡萄糖和乳酸三组各取健康新西兰兔16只，每组再分为高代谢脓毒症组和对照组两部分，建模方法同第一部分；2）三组分别先静脉弹丸式推注再持续灌注13C标记的亮氨酸、葡萄糖和乳酸；3）灌注前抽取动脉血作为背景值，灌注达150，160，170和180min分别抽取动脉血2ml用于质谱分析；4）实验开始后前30min中每5min收集呼出气一次，随后每30min收集呼出气一次，用于气相质谱分析；5）血样经过低温离心取上清液，过阳离子及阴离子交换树脂，再经衍生化处理；6）处理过的血样进入气相色谱－质谱仪，测量其13C标记的亮氨酸、葡萄糖和乳酸丰度；7）实验兔的呼出气通过13CO2气相质谱分析仪测定其中的13CO2丰度（E13CO2）；8）利用文献提供的公式算出CO2总生成率（V13CO2）以及机体各物质的通量、氧化速率以及物质代谢百分比等；9）数据分析处理采用t检验。

Crime Show Matai character hot sand, to delicate ruthless known Heibailiangdao, in an anti-drug operation, he was surprised to discover that drug traffickers even have their own brother-in Iowa, he will be in the hunt for Iowa grasp, A China and begged him to let him once, because the transaction involves huge sums of money he loss of the lives of themselves and their families will not be maintained.

重案组沙展马泰性格火爆，以辣手无情闻名黑白两道，在一次扫毒行动中，他意外发现毒贩中竟然有自己的小舅子阿华，在追缉中他将阿华抓住，阿华求他放过他一次，因为这次交易涉及巨额资金，如果丢失自己及家人一定性命不保。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
