Corsair SSD – Extreme Series
2010年3月30日
总是蠢蠢欲动想尝试最新的东西。当初图kingston的SSD便宜，就换了，但是心里还是有点不甘，因为kingston的速度有点慢，所以价格便宜呀。这次正好借着这个机会，把kingston的SSD装到上网本，买个Corsair的Extreme系列SSD装在主力电脑上，这下应该到位了，速度也没让我失望，哈哈哈。生命就是在于折腾，圆满了！

再战Bunyip
2009年3月30日
自从黑色星期六的大火，bunyip state park一直处于关闭状态。上周末好不容易对外开放了，戴哥和油饼就按捏不足内心对越野的渴望，一起驾车来到bunyip state park，随行的还有摄影兼摄像师Wilson和油饼的“小蜜”（具体哪个MM，俺也不太清楚）
想看更多照片 http://www.auoutdoors.com/bbs/redirect.php?tid=318&goto=lastpost#lastpost
路虎Defender越野
2009年3月14日
今天有幸做戴哥新买的Defender去越野，实在太强大了，让俺萌生了换车的念头。
这种不好的想法一定要在萌芽的时候就打压。 
开车defender太轻松了，没有任何难度。车是很强，但是技术还是需要提高啊！
天公不作美，下起大雨了，为了安全吃了午饭就打道回府了。
[转帖]纸上谈兵：曾经丧心病狂的Nikon及其MF牛头漫谈
2009年3月4日
NIKON作为相机及镜头大厂，几十年来生产了不少为人称道的好镜头，这些大伙都已经概括得差不多了。但是Nikon在70、80年代随着F2和F3的推出，其丧心病狂的症状是很值得说一说的，这些症状主要表现在生产了一些非常“新蜜蜂”的手动镜头。而所谓新蜜蜂者，定义较含糊，姑且认定为价格高昂、生产量/拥有量少、具有里程碑式意义而并不一定同时具有很大的实际意义的、在我们一般摄友手上比较难得一见的镜头。所以我这篇东西基本上是没有什么现实意义的。另外Nikon现在也越来越表现正常，没有以前那么丧心病狂了。
题目也说了是纸上谈兵，这些牛头我一个也没有，一个也没用过，有些更连见都没见过。真的是没吃过猪肉而且连猪跑也没见过了。虽有贻笑大方之嫌，但是并不妨碍我许久以来对这些镜头的关注、资料的收集整理以及我这篇狗屁文章的诞生，essay也是这样写成的嘛。 废话不说了，转入正题。
Fisheye-Nikkor 6mm f/2.8 Auto
都说NIKON的广角好，那么就再说广一点，从鱼眼头开始说吧。NIKON从1962年推出第一支鱼眼镜头，8mm/8.0，但是真正新蜜蜂的鱼眼头是在Nikon F2推出后，在其丧心病狂症真正开始发作的时候的1972年推出的极致看家头Fisheye-Nikkor 6mm/2.8 AUTO。此头从1972年首产一直到1998年结束生产，一共出了三代（也有说四代的），分别是非AI版，AI（1977年始）和AI-S（1982年始）版，都是12片9组结构。此头为什么牛？因为它是极端的6mm，因为它有220度超乎想象的视场角，因为它那直径20厘米的前组镜片，因为它5.2公斤的重量……此头的前组镜片中央厚度为7mm，但是边缘厚度达到60mm，最近对焦距离为25cm（第一代为30cm），当光圈收到f/22的时候，其景深范围从17厘米到无限远（还对什么鸟焦呢？），使用的时候要预升反光板。此头甫推出时，让全球摄影器材界都打了个喷嚏。直至今天，这个6mm头依然是35mm照相机镜头里焦距最短的镜头。
这个镜头，平时不用的时候可能最好的用处是拿来挂墙上当装饰，相信不知道的人会以为是壁灯。
Nikon当然也出了很多其他的鱼眼镜头，比如6mm/5.6，7.5mm/5.6，8mm/2.8，8mm/8，10mmOP/5.6等。但是有哪一支能比这支牛呢？其它视场角小于180度的超广角已经不是鱼眼，不说也罢。

And so this age old debate continues…but which one of these fuels really does reign supreme at the pumps? Let’s take it in turn to discuss both the pros and cons of each one.
In the blue corner: Weighing in at an average 95.9p/ltr, the petrol engine packs quite the punch. The most popular (some may argue most common) option for motorists, cars with petrol engines are more much quieter and faster than its main opponent. Petrol engines are much lighter therefore offering a much more responsive drive, on the whole. At the forecourts, motorists with petrol engines have an option of unleaded or super-unleaded fuel. The difference between both is their Research Octane Rating (RON), which rates performance levels. Unleaded and Super-Unleaded have RON of 95 and 98 respectively, which indicates that super-unleaded petrol hold a higher performance than unleaded (the higher the RON the better performance). Petrol engines are much more easily repaired and require fewer services. Nonetheless, with an average petrol car emitting approx 214g/km of CO2, petrol engines are less friendly to the environment. Although with an increase in customers looking for more environmentally friendly cars, Seat have introduced Seat Ibiza 1.2 with low CO2 emissions, and an average of 47.9mpg, petrol cars are becoming more aware of the importance of being environmentally friendly.
In the red corner: Weighing in at an average 109.3p/ltr, the diesel engine is an underdog in the fuel stakes. But none the less is becoming an increasingly popular choice among motorists. Diesel engines are well renowned for being much more environmentally friendly with a lower CO2 emission rate, with an average diesel vehicle emitting 196g/km of CO2. Diesel engines are on the whole heavier than petrol, however this comes with a distinct advantage as diesel engines have more torque. Which in turn means that they are much better performers for pulling or travelling up hill. For motorists travelling long distances, diesel engines (although costing more p/ltr at the pumps) are much more effective as, the more miles travelled the better the value of the fuel the motorist receives, take Renault with their Megane Expression which gives efficient fuel consumption with an average 64 mpg. Other benefits of having a diesel powered vehicle are that the motorist pays less tax compared to its petrol counterparts.
So there we have it, in a nutshell, diesel cars are more costly to buy, and more costly in upkeep, nevertheless, they have less depreciation and hold their value very well in re-sell. Petrol cars on the other hand are cheaper to buy and even cheaper to run, however with high emission rates petrol cars are less environmentally friendly. Choosing which engine you want depends solely on the purpose you your vehicle. Looking to travel the length and breadth of the country? Then a diesel engine may be better suited to you. Looking for a nippy little cost effective run around? Perhaps you’ll be more in favour of a petrol engine instead.
Both fuel types have their benefits and drawbacks. To say which one takes the crown in the fuel stakes is in turn impossible to conclude. Settling this debate is as hard as choosing which action hero is better…

无线电通信天线增益
2009年1月20日
增益是指：在输入功率相等的条件下，实际天线与理想的辐射单元在空间同一点处所产生的信号的功率密度之比。它定量地描述一个天线把输入功率集中辐射的程度。增益显然与天线方向图有密切的关系，方向图主瓣越窄，副瓣越小，增益越高。
可以这样来理解增益的物理含义 —— 为在一定的距离上的某点处产生一定大小的信号，如果用理想的无方向性点源作为发射天线，需要 100W 的输入功率，而用增益为 G = 13 dB = 20 的某定向天线作为发射天线时，输入功率只需 100 / 20 = 5W 。换言之，某天线的增益，就其最大辐射方向上的辐射效果来说，与无方向性的理想点源相比，把输入功率放大的倍数。
