The Douglas Mawson Antarctic Expedition of 1912 is one of the most amazing feats of endurance of all time.

长期以来，1912年的道格拉斯·莫森南极之旅因其忍耐力的超群而为世人所折服。

"Douglas Mawson was this mildmanneredperson who turned intosomeone incredibly hard to kill,"says veteran Antarctic guide DaveHahn.

"道格拉斯·莫森原本是个性情温和的人，而后来这个人却变得坚强得令人吃惊。"经验丰富的南极导游戴夫·哈恩这样说。

The recent introduction of 384 kbps satellite data links to Casey, Davis and Mawson (plus 256 kbps to Macquarie Island) means the Australian Antarctic Division can fully embrace the benefits of VoIP already enjoyed by the rest of the world.

最近通往 Casey、Davis、和 Mawson 刚升级为 384 kbps 的卫星数据连线(加上 256kbps 到 Macquarie 岛)意味著澳洲环境、水、遗产及艺术部南极司，可以完全享有在世界的其他角落早已拥有的便利通讯。

From base camp, inCommonwealth Bay, Mawson setoff with a dog handler named BelgraveNinnis and world ski championXavier Mertz to explore theinterior.

从英联邦海湾的基地开始，莫森和雪撬犬训练员——贝尔格雷夫·尼尼斯，世界滑雪冠军——泽维尔·蒙茨三人一起出发了，他们要到南极的深处去探险。

The phenomenon on issue of the ozone hole or ozone reduction in the South Pole or north hole and other midlatitude areas happens in recent years, and more and more attentions are paid to this big phenomenon caused by the human activities.

近些年来，南极地区、北极上空和其他中纬度地区都出现了不同程度的臭氧层耗损现象，人类活动引起的大气臭氧损耗日益得到大家的关注。

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。
