This paper introduced a set of brandnew mobile air lifting technology for acidulation and cleanup by using the mature matching skill of downhole air pumping with the mobile injection equipment of surface nitrogen gas generation system.

应用成熟的气举采油井下配套技术，结合可以移动的地面制氮注入设备，形成了一套全新的移动式气举酸化排液技术，从而发展了塔里木油田的气举采油技术，并在塔里木哈得油田试验和推广应用中见到了较好的经济效益。

An enumerable object is typically an instance of a compiler-generated enumerable class that encapsulates the code in the iterator block and implements the enumerable interfaces, but other methods of implementation are possible.

典型的可枚举对象是由编译器自动生成的封装了迭代器块中的代码并实现了可枚举接口的可枚举类的实例，但其他的实现也是允许的。

First, the station-oriented enumerative procedure is improved and extended to generate the enumerative tree; second, the bounding rules are developed and applied to reduce the enumeration effort. As a result, the balance can be optimized rapidly.

首先，通过改进现有的工位枚举策略，并将其扩展用来生成基于工位的枚举树；其次，通过研究与应用相关定界方法来减少枚举树的大小，使平衡能快速达到最优解。

Thus, each returned enumerator has its own state and changes in one enumerator will not affect another.

因此，每个被返回的枚举器具有其自己的状态，并且一个枚举器和其它枚举器互不影响。

This second hoist device can good match with the four-post hoist, it is used to take down tires, repairing the motorcar chassis, angle measure and wheel alignment.

本课题设计的二次举升小车是一种配合四柱式汽车举升机使用的二次汽车举升设备。便于轮胎拆卸、底盘检修、车轮角度测量和车轮定位。

Plunger lift is one of most efficient lift manner in intermittent lift.

柱塞气举是间歇气举中最有效的举升方式之一。

Kinematic simulation is conducted on the mechanism.Integrating simulation technology, finite element analysis and optimal design technology, structure optimizing and light weight design are conducted on some key components in the lifting mechanism.After shape and dimension optimization on the triangle plate in lifting mechanism,its mass is ddecreased by 5.48 kg while the stress level is only increas.

将仿真技术、有限元分析和优化设计技术相结合，对举升机构中的关键零部件的结构进行优化和轻量化设计，对举升机构中的三角板进行形状尺寸优化后，在质量减轻5.48kg的情况下，应力水平仅增加6.1MPa，小于许用应力，完全能够满足举升工作要求。

The difference is that the relay-like plunger is composed by two separated plungers in different size and reciprocate in corresponding tube in the process of lifting, and the two separated plungers automatically dock with each other when the relay-like plunger is in the process of up stroke and separate in the process of down stroke and constitute the process of the relay plunger lifting.

所不同的是，组合油管接力式柱塞举升系统的卡定器下到下部小油管中，柱塞由大、小两个分体式柱塞组成：小柱塞在下部小油管内运动并实现在小油管中的举升，大柱塞在上部大油管内运动，上行程时小柱塞可与大柱塞自动对接并完成举升的接力，下行程时小柱塞可与大柱塞自动脱离。

An object of enumeration type may be initialized or assigned only by one of its enumerators or by another object of the same enumeration type

枚举类型的对象的初始化或赋值，只能通过其枚举成员或同一枚举类型的其他对象来进行

Recall that an object of enum type may be initialized only by another object of that enum type or one of its enumerators Section 2.7, p.

回顾枚举类型 enum，我们知道这种类型的对象只能用同一枚举类型的另一个对象或一个枚举成员进行初始化（第 2.7 节）。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
