“萨尔”-6轻型护卫舰
萨尔” -6 轻型护卫舰萨尔” -6 的基本概貌“萨尔” -6级护卫舰舰体以K130护卫舰为原型，但水线以上的建筑、设备经过了重新设计，由德国和以色列的设计部门共同完成。
该舰的舰体在德国建造，舰载武器系统、作战系统和雷达电子系统由以色列自己配置。
该型舰的舰体造价约1.2 亿美元，加上以色列为其配装的舰载武器和各种设备，总造价约2.6亿美元，在目前国际1〜2千吨级的轻护舰市场上，算得上是优质低价了。
萨尔” -6 级护卫舰长90 米，宽13 米，吃水3.5 米，最大航速35 节，22 节航速时最大续航力4500 海里。
标准排水量2000 吨，舰员编制60 人，另可搭载舰载机航空人员10人。
在不重新补充的情况下，自带的燃料和给养可在海上实现自持7 天，如可进行海上补给，则可以延长到21 天。
萨尔” -6 级护卫舰上实现了现代宜居标准，舰员休息区域的每个舱室都设有独立卫生设施，并为将来扩展任务时增加舰员预留了空间：士官2 至4 人一间，带有独立的卫生舰长套房包括1 个套间、工作间、休息室和浴室。
舰内安装了2 套技术先进的自给式通风系统。
在舰上安全区域装备了综合模块化空气净化设备，提供独立的过压外泄能力，保证受污染的空气不进入舰内。
间，可解决男女舰员同舰而居的不便；军官每人 1 个房间；萨尔” -6 的外形特点萨尔” -6 级护卫舰与K130 级轻型护卫舰一样，采用传统的单体船型，舰体线条经过优化，水线以上采用曲线倾斜设计。
这使得在较为高速的情况下，狭窄的舰首向两舷的外飘减少了阻力和波浪的影响，提高了抗浪性。
舰体外形紧凑，舰体从正面看呈X 形，许多设备和小部件都隐藏在高高的防浪板后，并在救生艇和武器发射装置上也加装了雷达伪装网。
舰体后部是一个长24 米的飞行甲板，用于起降直升飞机，也可用于起降遥控的无人飞机。
舰上没有机库，但设有直升机加油站，并且在两舷装有减摇装置，不但有利于舰船的机动，而且具有稳定作用。

Deep sea creatures
Six-Gill Shark 六鳃鲨
Six-gill sharks, like this one off the coast of Vancouver, cruise the ocean floor during the day, sometimes as deep as 8,200 feet (2,500 meters), then move toward the surface at night to feed. They can reach impressive lengths of 16 feet (4.8 meters) on a diet of other sharks, rays, squids, crabs, and occasionally seals.
Pacific Viperfish 太平洋蝰鱼
The Pacific viperfish has jagged, needlelike teeth so outsized it can't close its mouth. These deep-sea demons reach only about 8 inches (25 centimeters) long. They troll the depths up to 13,000 feet (4,400 meters) below, luring prey with bioluminescent photophores on their bellies.
Fangtooth Fish 尖牙鱼
The nightmarish fangtooth is among the deepest-living fish ever discovered. The fish's normal habitat ranges as high as about 6,500 feet (2,000 meters), but it has been found swimming at icy, crushing depths near 16,500 feet (5,000 meters). Fangtooth fish reach only about six inches (16 centimeters) long, but their namesake teeth are the largest, proportionate to body size, of any fish.

The Sears Holdings Approach
Key to our Approach: 1) allowing users to continue to use familiar consumption interfaces 2) providing inherent HA 3) enabling businesses to unlock previously unusable data
• Enterprise solutions using Hadoop must be an eco-system • Large companies have a complex environment:
• Transactional system • Services • EDW and Data marts • Reporting tools and needs
