Ti快门是快门技术不成熟时期的怪胎，而且事实上有很多爆裂的报告
现在F6/D200/D2x/D2H上面的铝片快门跟FM2n的铝快门是一个系列。

发帖数: 1173 | 6 Some interesting information came in today - basically more details on the
already existing rumors:
■The Nikon D90 replacement will probably be called Nikon D95.
■Magnesium body. Previous reports indicated that parts of the body will be
aluminium. My guess here is that the body will be magnesium-alloy, just like
the D300s.
■16MP sensor (expected)
■1080 HD video.
■6 fps (FYI: Nikon D90 does 4.5fps, the D300s – 7fps). The initial report
was for 8fps. Let’s just say it will be somewhere between 6-8 |

发帖数: 7508 | 7 Nikon D90 replacement (probably called D95):
* Aluminium or magnesium-alloy body
* 16MP sensor
* 1080 HD video
* Somewhere between 6-8 fps
* Improved ISO (don't know what exactly the improvement is - higher ISO,
or just better ISO at the same D90 level)
* 39 AF points
* Price: $1199 for body only
* Announcement: on/around September 15th, 2010 |

The overwhelming medical and scientific opinion is that the findings
outlined above do not convincingly demonstrate a causal relationship between
aluminium and Alzheimer's disease, and that no useful medical or public
health recommendations can be made − at least at present (Massey and
Taylor 1989).

Despite the great numbers of metals and alloys known to man, remarkably few

relatively corrosive environment combined with the poor tolerance of the
body to even minute concentrations of most metallic corrosion products
eliminates from discussion most metallic materials. Of the possible metallic

My first impression of my new school is its’ neatness, straight paths
cutting the campus into different area, trees arranged in rows, bushes
trimmed; buildings were all tiled outside with large windows with aluminium

ECL can be an expensive reagent in a lab, and what with it being involved in
the final stage of a western blot, it’s something you don’t want to have
to worry about too much. During my PhD, I was struggling with my western
blots for ages – it seemed I was doing everything right, I just wasn’t
getting any signal in the dark room. At the time I was using a pre-made ECL,
and a friend that I shared lab space with suggested I try her home-made
