Then suddenly a little nail breaks,which had stopped the machine for a few moments;and now the wheels turn again,the floats break the force of the waters,and the ship continues its course;and the beam of the steam engine shortens the distance between far lands from hours into minutes.

就在这时，刚才导致发动机停止的小钉子被拔除，蒸汽轮又开始运转，带动轮涡轮排水浮动前进，轮船继续开始它的航程，从此，蒸汽轮船将人类漫长的旅程从数小时缩短为几分钟。

A half-Keystone cross-section top- ring with improved carbon scavenging abilities is used, and the groove for the top ring is made more durable with the adoption of a cooled ring carrier that increases the groove's cooling capability.

当与对压缩机的一侧，从而降低了刀片和之间的压缩机房屋清拆封严相结合，提供卓越的涡轮增压器，这些反应几乎所有的发动机转速。

With CAD/CAM integrated modeling technology and NC programming manufacturing to develop cold box process casting technology of engine cylinder block and cylinder head of linear four-cylinder,two-air valve mid-position cam,four-stroke direct-jet combustion chamber,drying cylinder sleeve turbocharged and oil intercooled diesel engine in accordance with EUROⅢ standard of automobile tail gas exhaust.

运用 CAD /CAM一体化复合建模与数控编程加工技术，研究开发了符合欧Ⅲ汽车排放标准的直列四缸、二气门中置凸轮、四冲程直喷燃烧室、干式缸套涡轮增压和机油中冷式柴油发动机缸体缸盖冷芯盒铸造成形工艺。

The damage analysis of cracked turbine disk in the rocket engine is described. From a series of analyses, the causes of failure were reasoned through calculation and experiments, fatigue analyses which include stimulating vibration test and fatigue strength calculation were emphasized.

针对某火箭发动机涡轮盘在热试车中出现的裂纹故障，进行全面的分析，准确定位故障类型，以试验和计算分析给出合理的故障原因，重点是在疲劳分析方面所做的工作，包括振动模拟试验、疲劳强度计算，并根据疲劳强度分析结果提出改进方案。

These engines deal with larger comparative airflows and lower jet velocities than the pure jet engine, thus giving a propulsive efficiency (Part 21) which is comparable to that of the turbo-prop and exceeds that of the pure jet engine fig.

因而，其推进效率(第21章)与涡轮螺旋桨的相当，超过了纯喷气发动机的推进效率(图1-lO)。

Turbo diesels are probably going to be included as well.

涡轮增压柴油发动机很可能将被列入的。

For the performance S3 model, expect to see a new turbocharged four-cylinder engine.

为履行三模式，希望看到一个新的涡轮增压四缸发动机。

The Porsche version would feature a twin-turbocharged four-cylinder with between 280 and 300 hp moving about 2650 pounds.

保时捷版将采用双涡轮增压4缸发动机与280和300之间，惠普走动二千六百五十零磅。

In a gas generator cycle engine, the turbine flow is in parallel with the thrust chamber and is not used to develop thrust.

在一个燃气发生器循环发动机，涡轮流量是在平行与推力室和不被用于发展的主旨。

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。
