He found that the interval of an octave is rooted in the ratio 2:1,that of the fifth in 32,that of the fourth in 4:3.and that of the whole tone in9:8.the phthagoreans applied these ratios to lengths of a string on an instrument called a canon,or monochord(a board with two bridges between which a string is stretched and a third bridge that divide the string in two parts);and thereby were able to determine mathematically the intonation of an entire musical system.

毕达哥拉斯将这些弦长比例应用于一种叫做卡农的乐器上，卡农也可以称之为单弦琴或者单弦音响测定器（是一个由两个码构成的木板，码子之间有一条被拉伸的琴弦，第三个码子位于琴弦两端的码子之间），因此能够用数学的方法测定整个音乐系统的音调。

以拉线塔中线绝缘子串为分析对象，通过对横担、拉线铅锤面间的距离分析，再将绝缘子的串长、角度，导线风偏角、弧垂投影至拉线铅锤面，在拉线铅锤面建立中线绝缘子串的轨迹方程，以带电体与拉线间的距离为限制条件，从不同角度计算出第1、2、3极限风偏角，取其中的最小值为极限风偏角。

Practically all Python objects have a string presentation either evaluatable from repr( or '', or printable from str. The print statement automatically invokes the str function for an object. This gets even better. When you are defining your own objects, there are hooks for you to create string representations of your object such that repr and str (and '' and print) return an appropriate string as output. And if worse comes to worst and neither repr or str is able to display an object, the Pythonic default is at least to give you something of the format

事实上，所有的Python对象都有一个字符串表示形式（通过repr函数，''或者str函数来展现）。print语句自动为每个对象调用该对象的str方法，这种机制的一个额外的好处就是在你定义你自己的对象时，你可以利用这种机制定义repr(，str或者''或者print来为你的对象创建一种字符串表达形式，它可以在被调用时返回适当的字符串描述信息，这样即使在坏的不能再坏的情况下，repr或者str起码可以给你返回一个对象的信息，Pythonic方式的默认做法是起码给你返回想如下格式的信息
