发烧从头开始

发烧从头开始,顺便科普一下插座的知识,呵呵。
常常看到一些音响插座卖家说自己的插座是纯铜的,我看了只是偷笑,大家都知道,纯铜在空气中几小时

就会氧化,如果有水汽更快了,还有就是插座应该具有一定的硬度和弹性,这样接触才会好。所以网上说

纯铜的插座,绝对是忽悠。插座一般是黄铜,磷青铜的。应为具有一定的硬度和弹性,不过还是容易氧化

,一般使用10年就要更换,要抗氧化好一点的外面镀一层镍就好了,这就是所谓的医用级的,还要更强的

抗氧化,耐腐蚀的怎么办呢?很简单,外面镀一层铂金,船用的就是这种,所以说插座会影响音质是有科

学根据的,大家都知道不同的金属导电能力是不同的,当然插座是黄铜,镀镍,镀铂金导电就不一样,对

电流反应速度也就不一样,声音也就不一样,原因暂时不明,好了,材料分析完了,还有就是插座弹片结

构不一样声音也会不一样,接触的越紧越好,接触面越大越好,进一步分析发现,当接触面越光滑,相对

应的接触面也就越大,所以接触面我们都尽量处理的光滑一点,还有市面上的发烧插座,表面镀金,镀银

,镀铂金也是这些插座的延伸,按接插件标准来讲一般有3层,金,银,还有铂金。具体怎么搞我是不懂

的,但是表层最好要耐磨,导电强一点更好,接触紧一些,接触面大,抗氧化,抓住插座这些特点,选插

座就很容易了,说穿了还是金属表层原子排列和物理特性导致插座声音不同,这些都不是玄学,是真正的

科学,认识有限难免存在错误之处,还请大家指出不足,谢谢大家耐心看完!

看完了,不错楼主讲的很好

你好,我这有一种老插头是英国60年代产的,应是紫铜但不知道外面镀的是什么请帮忙看看。谢谢!
晚上可能光线不好。

看这样的成色可能是黄铜的,不过已经氧化了,真不知道60年代有没有镀金的技术,就算有可能也磨掉了。

The swelling index of GDP and retired teacher - re

"the swelling index of" "gdp" and "retired teacher" "material of swelling index of" "gdp" and "retired teacher" for more than three years,casque beats, rising prices?china's "gdp", added a number?the author does not know.
however, over the past three years,sac louis vuttin pas cher, in rural senior middle school retired teacher (hereinafter referred to as: high school), even the "penny" did not rise,louis vuitton,casque beats pas cher, not to increase wages,louis vuitton, true it may be said: "as unalterable principles".
because of rising prices, city workers,sac louis vuitton, won the "living allowance".however, rural high school retired teacher,sac louis vuitton, does not belong to the city staff, no "allowance", this is also the "mandate of heaven" is doomed.
rural high school retired teacher, became the "inflation",zhou zian 39 the health blog, "gdp" increase ",louis vuitton pas cher, town dweller income rise" offbeat "groups", also be "cent cake" forgotten "offbeat".- this really dumbfounding, very sorry.in 2009, the national civil servant "," salary reform, rural high school retired teacher,louis vuitton sac,louis vuitton sito ufficiale, does not belong to the reform of the wage list.
although the "a" gift, but again much less (and the "public servants" compared to).note: according to increase wages, must wait for the next bus "".but over the past three years, "bus ding", difficult to achieve.
more than three years,louis vuitton borse, three years ago, "wen" real ",louis vuitton artsy,louis vuitton outlet, this is reality.rural high school retired teacher, when can sit on the "express"?when can substantially below the national "civil servants" salary?the great promise, will be "right now"?it seems, it will be "god knows how long"!rural high school retired teacher, is able to withstand the fast rising prices?the author is difficult to understand.
now in my school a teacher for example: (title: senior secondary school teacher, having taught for forty years.now the pension in total: 2400 yuan).this really is "paid"?this was the "forgotten group", can withstand the price rise quickly?prices rise, "gdp" has increased, people's lives are improved.
this was the "cake" forgotten "groups", also belongs to the chinese citizens in one, but also should be "gdp" by henry,zhen huan biography beauty modern beauty as they a,hearing of 39 health blog,casque monster beats, wages should rise, life should also be improved,liu shijing 39 the health blog, this is be perfectly logical and reasonable and legitimate.
i look forward to: our "cake", in the "cake", should see this "forgotten group".announced at the national "income of urban residents rose", should see this is "forgotten" groups, their income is also i
