It's all relative. Saying the S is quieter or noisier than a "Lexus" is a
bit misleading as it depends on which Lexus you compare it to. Same is true
with any other manufacturer. The Lexus LS600hL just happens to be the top of
the line Lexus and there aren't many cars on the road that are quieter. But
if you compared the S to say the Lexus IS250 I'm sure the S would be
quieter. Same could be said if you compared the S to the Ford Fu... 阅读全帖 |

Get Ready, Asia: China's Military Is Rapidly Catching Up to America

In considering Paul Dibb’s analysis on the Chinese People’s Liberation
Army (PLA), I’d recommend anyone interested in the state of China’s
military start by reading Roger Cliff’s China’s Military Power: Assessing
Current and Future Capabilities. Cliff argues that “…by 2020, the quality

“The military’s latest secret assessment of China’s rapidly modernizing
submarines has good news and bad news for the U.S. Navy. On one hand, the
roughly 60 submarines in the People’s Liberation Army Navy (PLAN) fleet are
spending more and more time on combat-ready patrols — signaling China’s
increasing naval competence and growing seriousness about influencing the
western Pacific Ocean.

Assuming the Chinese stay with their current sub designs, American
submarines should be capable of swiftly defeating Chinese boats in any
potential future shooting war — helping clear the way for U.S. aircraft
carriers to strike Chinese land targets. Combined with a slowdown in Chinese
sub production, and the recent doubling of America’s submarine build-rate,
the noise revelation could lead to a radical recalculation of the Pacific

E320 CDI because of tax credit, but a lot noisier and less safe. Jetta doesn

around in the engine bay when it is running. hoho. I mean it vibrates a lot.
The I6 CDI engine is very quiet with little vibration. If VW sells a TDI

不过噪音，不是你就是编辑在撒谎，要么就是听力有巨大差别：
Perhaps the one flaw in the performance department is the road noise. Over
various surfaces, from concrete highways to aging pavement, my co-driver and
I both thought the Escape was a bit noisier than the competition,
especially the new CR-V and Equinox. It's not a glaring problem and it
certainly isn't as raucous as the Sportage or Hyundai Tucson, but it's
something to pay attention to on a test drive. |

this convertible(weights 400 additional LBs on convertible). And it takes
premium gas. If I wanted to save gas, I'd have gotten a BRZ manual. I got
G37 so I could floor it and get out of slow traffic easily.
MPG on Manual G37s is about the same but manual offers more fun and slower
acceleration.
I'd recommend BRZ manual for fun and higher MPG, though it's noisier and

Diesel engines have never really caught on in passenger cars. During the
late 1970's, diesel engines in passenger cars did see a surge in sales
because of the OPEC oil embargo (over half a million were sold in the U.S.),
but that is the only significant penetration that diesel engines have made
in the marketplace. Even though they are more efficient, there are eight

avoiding the D3000's overly contrasty, noisier images and free from the color smearing that is starting to affect the E-P2 at ISO 3200. Most impressive is the E-PL1's ability to produce results comparable with the EOS 500D and Pentax K-x, despite its smaller sensor. |

* Lens impressively sharp with generally good corner sharpness at wide apertures
* Reliable exposure metering and great color response make it easy to get good images
* Good high ISO capability for a small-sensor camera (and rarely needed thanks to the bright lens)

发帖数: 129 | 31 假如FF 有400个像素，每个像素2.5个光子
m43相同分辨率，每个像素也是2.5个光子
因为像素尺寸小，所以噪音大，m43信噪比差。画质必然是FF好
如果m43跟FF的像素尺寸一样大，噪音相同
每个像素有10个光子，m43信噪比好。不过损失了分辨率，画质谁好谁坏不好说
由此看来，“等效光圈”“总通光量”还是说明不了暗光下画质如何。
光线足够则是另外一回事了
光线足够，信噪比正比于光子数平方根。
如果分辨率相同，如你所说，m43要开到f/2才能达到FF在f/4下的画质
如果像素尺寸一样，m43在f/4时每个像素得到的光子数与FF在f/4下一样，信噪比一样
但依然损失分辨率，整个画面画质还是差

TypeScript won't reduce the number of bugs.
TypeScript does suffer from added complexity for generics. Take a look at
this generic identity function in standard JavaScript:
const identity = arg => arg;
Compare that to the much noisier statically typed function in TypeScript:

发帖数: 6890 | 35 很有意思的话题。对于问题２，我抄录网上的一些评论给大家看看。
This is still a small-sensor camera, so you will not get digital SLR-quality
photos and noise and artifacts will probably stop you from using them at
100 percent size even at ISO 80 (macro photos are an exception).
Images do get softer and noisier above ISO 200。Colors desaturate some at
ISO 1600 and 3200, subjects look very soft, and detail is greatly diminished
; ISO 6400 is sort of pointless. |
