1·The pressure gradient, as one of the most important parameters affecting design and operation of gas-lift wells, is the foundation of gas-lift well design.
压力梯度是气举井设计的基本依据，是影响气举井设计和运行的重要参数。
2·Aim To resolve the influence of pressure gradient, liquid hold-up and mixture density of the different flow model on the design and operation of gas-lift well in oil recovery.
目的解决深井气举采油过程中不同流动型态的压力梯度、持液率、混合物密度对气举井设计和运行影响的问题。
3·This augurs well for the Saudi elite, but one fancy new university will do little to lift the overall standard of Saudi education.
这所大学预告了沙国菁英前程似锦，但一所收费昂贵的新大学对于全面提升沙国教育各项标准并无多大用处。
4·The modern airplane design works well, but from a fuel efficiency standpoint, could planes be designed more aerodynamically — to lower drag and increase lift?
现代的飞机设计做得很好，但立足于燃料效率来看，飞机是否能设计得更符合空气动力学——降低阻力还是增加动力？
5·A man who knew him well in Indiana said he had often seen Lincoln grasp a barrel of cider and lift it to his face as if to drink.
一个在印第安纳州熟识他的人说，他经常看到林肯抓起一桶苹果酒举到脸前像要喝似的。
6·Weak consumption during the global upswing was down to low real-wage growth, as well as caution: falling inflation should lift real income and spending.
实际工资的缓慢增长以及小心谨慎构成了他们在全球繁荣期间消费依旧疲软的重要原因。如今通胀的回落应该可以抬升实际收入跟支出。
7·Forthwith, very smoothly and easily, they lift Phil into the carrying chair and take her on the perilous journey downstairs with her feet sticking well out in front because her knees won't bend.
于是很快，很容易就顺利地将菲尔抬进移动椅，并且因为她的膝盖不能弯曲所以使她的脚向前伸出着，然后带她下楼，开始危险的旅程。
8·For tactical reasons as well as moral ones, Israel should lift its economic siege.
出于战术和道德考虑，以色列应当解除它的经济封锁。
9·Economists expect that China will lift interest rates two or three more times this year as well as tightening loan quotas, raising bank reserve requirements, and permitting currency appreciation.
经济学家们预测，中国今年将再加息两至三次，同时将收紧贷款额度、上调银行存款准备金率并允许货币升值。
10·But it was a birdlike tail that really amped up the aerodynamics, dampening the drag from the body and wings, as well as boosting the lift that lags under vehicle weight and cargo load.
的确鸟儿尾巴一样的飞机尾部改善了空气动力学性能，缓解了机体和机翼的阻力，同时还大大的增加了向上的力，缓释了由于飞机本身和货物重量而产生的向下的力。
