海平面

The Afars say their real concerns are more prosaic: water, grazing and salt, which for centuries has been mined from the Danakil depression (in parts more than 300 metres below sea level) and taken up into Ethiopia's highlands by camel caravan.

阿法斯人说他们实际关注的只是民生问题：水，牧业和盐，这些物资几个世纪以来都是从达纳基尔低地（部分地区低于海平面300米）获得并用驼队运至埃塞俄比亚的高地。

Also shifted the engineering plan from a sea-level canal to a lock canal.

美国也转向工程计划从海平面运河锁定运河。

Any canal at Panama-a lock canal, a sea-level canal-would have to cross the river at least once.

任何运河在巴拿马举行了运河船闸，海平面运河将要过河至少一次。

Compared to the respectively alone stress, cold + 5 km hypoxia (4 hours/day, continuation for 2 days) and restraint + 5 km hypoxia combinated stresses significantly inhibited body weight gain of rats, and the five stresses also markedly decreased hepatic glycogen contents, and increased plasma glucagon levels. 2. Effect of continual hypoxia on the level of insulin secretion Compared to the sea level normoxia control group, simulated continual 2 km hypoxia for 1-25 days (1, 2, 5, 10,15 and 25 days) did not significantly influence rats body weight, food intake and plasma insulin level.

连续性低氧对胰岛素分泌水平的影响与海平面常氧对照组相比，模拟2km连续低氧1-25天(1、2、5、10、15和25天)没有明显影响大鼠体重变化、摄食量和血浆胰岛素水平，但在低氧第2天显著升高肝糖原含量和血糖水平，在第10天明显升高血浆胰高血糖素水平，在第1天血浆皮质酮水平显著升高，在第1和第2天瘦素水平明显上升，然而在第5天瘦素水平显著下降。

In deep water artesian well, be close to to make artesian well slop can send sea level above from pump of the bottom of a well 80 - on the derrick floor of 100ft.

在深水钻井中，为了使钻井泥浆能从井底泵送到海平面以上接近80－100ft的钻台上。

The Glomar Challenger定位到原文第二段第二句Using techniques first developed for the offshore oil and gas industry,the DSDP's drill ship,the Glomar Challenger,was able to maintain a steady position on the ocean's surface and drill in very deep waters extracting samples of sediments and rock from the ocean floor.

推理判断题[考频：66]。原文第二段讲述了对海底进行第一次探索的情况。对海底首次进行探索始于 1968年的深海钻井工程，而在这一工程中发挥了主要作用的正是Glomar Challenger，它能在海平面上保持稳定并且能够钻入深水中，从而抽取样本。故D正确。

"Radio altimeters measure the distance of an aircraft above the ground rather than above sea level, they are used in automatic navigation and blind-landing systems."

无线电高度表测量的是飞机离地面而不是离海平面的距离，用于自动导航及仪表着陆系统上。

Scientists do not know why dinosaurs became extinct, but some theories postulate that changers in geography, climate, and sea levels were responsible.

科学家不知道恐龙为何绝种了，但是一些理论推断是地理，气候和海平面的变化造成的。理论到实践的转变。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
