发帖数: 1107 | 4 我用的razer black widow，用起来很爽。就是这个：
http://www.amazon.com/exec/obidos/ASIN/B003ZJ1VD8/top-rated-pro
这个好像是青轴的，记得版上的大侠说过，这个好像是razer自己家改过的，
键程比普通的要段一些。
其他的机械键盘我没用过，就苦b的用过这一款，主要用来coding，
感觉非常爽，感觉敲代码都是一种享受。很多时候能copy都不copy，而是一个一个敲进
去。
不过razer的东西吧，就是太不抗用了。这个键盘大概每过几个月，就会有几个键位出
现double tap，就是按一下，然后会出两次效果。所以每隔几个月就得清洗一次。我最
早用WD40洗，但是洗完以后里面太埋汰了。后来按照网上介绍的方法，把所有键拆下来
，然后把无水酒精灌进去，洗完晾干就行了。
razer的鼠标也是，我这个death adder用着非常爽，定位相当精确，微动我也很喜欢，
就是经常变双击鼠，也得定期的用WD40洗微动。
不怕折腾就上razer吧，不过洗鼠标这个是必备技能，我一个罗技马拉松用了快5年了，
现在还在办公室用。 |

发帖数: 7639 | 10 Remember: if a system doesn't contain laplacian multiplier s,
it is a pure proportional system and always stable.
I think your feed-back equation is not correct:
say a neg-feed is given to input X(t) from output Y(t)
as C2*Y(t), where Y(t) = C1*X'(t) + C0,
X'(t) is the output of adder at input, as
X'(t) = X(t) - C2*Y(t), substitute Y(t) = C1*X'(t) + C0,
we have
X'(t) = (X(t) - C0*C2) / (1+C1*C2),
so the final transfer function is
Y(t) = C1*X'(t) + C0
= C1*(X(t) - C0*C2)/(1+C1*C2) + C0

Thinking C1 C2 are both posstive factors, this system

我觉得这里还是有点问题

，三角头，这是不对的。三角头、粗短身材只是蝰蛇科的常见特征，而眼镜蛇科的毒蛇
大多是细长身材椭圆头哦……
基本上毒蛇都来自上面说的蝰蛇和眼镜蛇这两科，当然，这么说也不是绝对准确。一个
问题是，虽然大多数常见的游蛇科的种类都是无毒蛇，或者微毒，但也有极个别的特例
，比如分布在撒哈拉以南的非洲树蛇（boomslang）
就有能力致人死命。第二个问题是海蛇的分类。一般认为海蛇是眼镜蛇科的一个亚科，
但也有人把它们单独列为一科。海蛇往往比陆生毒蛇的毒液毒性更强，比如白式海蛇（
Belcher's sea snake）
它的毒液比任何一种陆生毒蛇的都要强得多。不过很少有人有机会接触到海蛇，而且即
使遇到，大多数海蛇也是非常温顺的动物，不到万不得已，不会咬人，即便咬了，80%
的可能性根本不会注射毒液，所以通常海蛇并不被认为是多么危险的动物，你在电视节
目里往往可以看到潜水员和它们自由的嬉戏，相安无事。
所以说，基本上毒蛇就是说的蝰蛇和眼镜蛇这两科啦。除了前面说的身材不同，这两科

之前说过了，毒蛇的另一大家子就是眼镜蛇科眼镜蛇亚科。顾名思义，眼睛蛇（cobra

受到威胁时脖子会变成扁平状。所有毒蛇里个人以为最有特色就是两大类，一个是响尾

，在非洲和亚洲分布都很广泛，也是印度四大毒蛇之一。除去能够展平的脖子外，眼镜
蛇的外形和通常的无毒蛇比较接近，细长，头也比较小，呈椭圆形。眼镜蛇属里有十多

传统的神经毒之外，往往还加入了血循毒的成份，如果喷到眼睛上，可以引起剧痛和暂
时性失明，重则永远见不到光明喽……这些种类的眼镜蛇又常被统称为射毒眼镜蛇（

说来奇怪，这些射毒眼睛蛇的分布很分裂，非洲很多，东南亚也很多，中间中东、印度
等地带貌似倒没有（难道是在非洲和东南亚分别进化的？）。除此之外，非洲有一个独
