动力冲程

The remainder of the power stroke is an adiabatic expansion.

动力冲程的后段是绝热膨胀过程。

"In a two-stroke cycle, the compression and power strokes of the four-stroke cycle are carried out without the inlet and exhaust strokes, in one upstroke and one downstroke of the piston and one revolution of the crankshaft."

在二冲程循环中，只有四冲程循环的压缩和动力冲程，而没有进气和排气冲程，在活塞的一个上升冲程、一个下降冲程，同时曲轴旋转一周后完成。

The unit adopts variable displacement hydraulic pump, hydraulic cylinder, movable pulley and broad belt to transmit power,has the charecteristics of abundant recovery and full use of power,minor fluctuation of electric motor load, low height of the unit, long stroke length and convinence of adjusting the stroke length and pumping speed, can realize the performance of being fast on the upstroke and slow on the downs...

该液压抽油机采用变量液压泵—液压缸—动带轮及宽胶带传递动力，具有功率回收利用充分、电动机负载波动小、整机高度较低、冲程长、冲程和冲次调节方便等特点，可实现上快下慢的工作状态，并具有失载与过载保护功能，是一种结构简单、重量轻、能耗少、载荷大的新型长冲程液压抽油机。

Likewise, if the ignition switch is turned off, there can be no power event, but the ignition must occur before the power stroke can take place.

同样，如果点火开关关闭时，就没有权力的情况下，但必须在点火前的动力冲程才能进行。

Since it is the only stroke and event that furnishes power to the crankshaft, it is usually called the power stroke, although it is sometimes called the expansion stroke for purposes of instruction.

因为它是唯一中风和事件外墙权力曲轴，它通常被称为动力冲程，虽然有时也被称为为教学用地规模扩展的中风。

While Atkinson's original engine design is no more than a historical curiosity, the Atkinson cycle, where the power stroke is longer than the compression stroke, is increasing in popularity due to the increase in fuel economy it provides.

尽管阿特金森的原发动机的设计，只不过是历史的好奇心，在阿特金森循环，其中动力冲程长度超过压缩冲程，是越来越受欢迎，由于在燃油经济增长提供。

"In a two- stroke cycle, the compression and power stroke s of the four- stroke cycle are carried out without the inlet and exhaust stroke s, in one up stroke and one down stroke of the piston and one revolution of the crankshaft."

在二冲程循环中，只有四冲程循环的压缩和动力冲程，而没有进气和排气冲程，在活塞的一个上升冲程、一个下降冲程，同时曲轴旋转一周后完成。

The highly efficient Atkinson-cycle engine, made possible by the Variable Valve Timing with intelligence system, allows the expansion/power stroke to be longer than the compression stroke so that combustion energy can be more effectively used for production of engine power.

高效的阿特金森循环发动机，作出与智能可变气门正时系统，可以使扩充/动力冲程要长于压缩冲程，使燃烧的能源可以更有效地用于生产发动机力量。

The compression, power, and exhaust strokes are identical to those of the diesel cycle.

其它3个冲程（压缩冲程、动力冲程、排气冲程）与柴油活塞循环相同。

To achieve high reliability rig build momentum across the company Petroleum Chi Chai attached great importance to develop a detailed implementation plan: first, optimizing the current oil market, the popular 4012-based long-stroke diesel engine supporting 1000kW diesel generating sets to meet our 7000 meters below the oil drilling rig for electric power demand in 2009 in the second half on the market; second, strengthen the 4012 Long-stroke diesel engine, and the supporting 1100kW diesel generator sets, China's oil industry to meet the full demand for electric power drill, the end of 2009 the completion of prototype evaluation.

为实现打造高可靠性钻机动力，中油济柴公司上下高度重视，制定详细的实施计划：第一步，优化目前在油田市场广受欢迎的4012型长冲程柴油机配套的1000kW 柴油发电机组，满足我国石油钻探7000米以下电动钻机对动力的需求，2009年下半年投放市场；第二步，强化4012型长冲程柴油机，配套1100kW 柴油发电机组，全面满足我国石油行业电动钻机动力的需求，2009年年底完成样机评定。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
