HARTFORD, Conn. — A new, Spanish-designed submarine has a weighty problem:
The vessel is more than 70 tons too heavy, and officials fear if it goes out
to sea, it will not be able to surface.
And a former Spanish official says the problem can be traced to a miscalcula

Review of liquid oxygen/methane rocket engine
摘要：
简要介绍了国外液氧/甲烷发动机的研究情况.重点论述了甲烷的特点及它用作液体
燃料的优缺点.液氧/甲烷发动机具有较高的性能,甲烷有好的再生冷却性能,是一个可供
选择的推进剂组合.但由于其密度比冲比液氧/煤油发动机低,使用安全性也不如煤油;性
能又比液氧/液氢发动机低,这些都限制了液氧/甲烷发动机的发展和应用.迄今为止,还
没有一个液氧/甲烷发动机型号开展研制工作,因而也就不可能有其使用的历史.

所需位置。这样不仅战士体力消耗大、所需人数多，而且速度慢。由于侦察技术的高度
发展，敌方炮火的反击速度非常快，因此要求火炮能有较快的发射速度。这样就必须在
敌炮火反击之前能发射足够量的炮弹，完成压制任务后迅速撤出阵地，转移到新阵地进
行发射，提高自身生存能力，由此要求火炮能在3～5分钟内撤出阵地。由于牵引火炮的

目前唯一一台没有变速箱的混动车（除了已经破产卖给中国的Fisker Karma）
Not counting the late Fisker Karma, the Honda Accord is the only hybrid
without a transmission. Eliminating gearchanges improves efficiency.
Inventing elegant solutions to complex problems is a Honda specialty. When
the first hybrids arrived in the U.S., Honda beat Toyota to the market,
barely, by simply installing a pancake AC motor ahead of the engine’s
flywheel. That design, called Integrated Motor Assist, was compact and
efficient but didn’t offer pu... 阅读全帖 |

What's Covered Under a Powertrain Warranty?
Simply put, this is a warranty on components of the vehicle's propulsion
system, such as the engine, transmission and other related pieces such as
the differential. Powertrain warranties also often cover just about anything
involved in bringing power to the wheels, including a car's driveshaft and
constant velocity joints.
It's important to note, however, that not everything under the hood is
covere... 阅读全帖 |
