发帖数: 1294 | 1 我家furnace和coil连接的plenum部分（中间银色亮亮的那片的里面）是sheetmetal做
的，但是里面根本就没seal，而且和furnace连接的地方有大的gap是裸露的。
想问问大家应该怎么修,并问问coil的黑色管子是做什么用的，铜管呢？
1 fix plenum: 把最前面的通风管子挪开，把里面的sheetmetal重新做然后seal好。
2 drop down coil on the top of furnace： 这样要cut黑色的管子，见图片，和白色
的水管。有谁知道黑色管子（接在coil）上的那个是做什么用的吗？切断这个管子会让
氟利昂跑掉，需要重新加氟吗？铜管是做什么用的呢？
谢谢大家！ |

你安全笼都挂了,sheetmetal薄厚,不过是80克纸还是70克纸的区别 |

The National Highway Traffic Safety Administration announced today that
Volvo Cars will receive an award for its continued focus on safety. Of
course, Volvo changed the car industry—and essentially invented the concept
of highway safety—in 1959 when it released a patent for the three-point
seatbelt to other automotive companies.

of vintage-car collectors in Scottsdale, Ariz., Thursday that they should
consider buying a Model S "while they're still available."
With a storied career that spanned BMW, Ford, Chrysler and General Motors,
Lutz has always been blunt and outspoken, separating himself from the
marketing-speak that pervades the auto industry.
Known in the industry as a "car guy," he's a lover of the Model S luxury

发帖数: 1294 | 16 非常感谢，我这张图外面看没问题，但是把中间银色的tape剥开就会发现sheetmetal和
下边的炉子及上边的coil之间都缝隙很大，没有密封，并且plenum的里侧和炉子顶端之
间有很大的一个gap没有任何东西覆盖。
之间看都挺难发现的，这些问题是另一个来quot的contractor发现的。 |

发帖数: 3483 | 18 Since the introduction of the third-generation Impreza, Subaru has been
making incremental improvements to the rally-bred WRX, first with a
significant bump in output for the 2009 MY and now the adoption of the STI's
widebody design for 2011. And not only does the five-door model benefit
from its pumped-up sibling's sheetmetal, but the sedan gets a much-needed
testosterone injection to boot.
With a 1.5 inch-wider track front and rear, the 2011 Subaru Impreza WRX's

发帖数: 5723 | 20 不对哦，BMW官方发布的时候是88 lbs lighter than E90：
The 3 Series has grown 3.7 inches in length and 1.9 inches in wheelbase, but
the car is approximately 88 pounds lighter than the E90 thanks to the
lighter base engine, increased use of high-strength steel, plastics,
composites, and aluminum in the interior and chassis. The new car retains
its 50/50 weight balance. The car wears fresh sheetmetal with more creases,
although the overall silhouette is instantly recognizable as a 3 Series. The
