描述----------Description----------
The tau data frame has 60 rows and 2 columns.
tau数据框有60行2列。
The tau particle is a heavy electron-like particle discovered in the 1970's by Martin Perl at the Stanford Linear Accelerator Center. Soon after its production the tau particle decays into various collections of more stable particles. About 86% of the time the decay involves just one charged particle. This rate has been measured independently 13 times.
牛头粒子是一个沉重的电子一样的粒子，在斯坦福线性加速器中心在1970年发现了马丁的Perl。后不久，其生产头粒子衰变到更稳定的粒子的各种藏品。约86％的时间衰变涉及一个带电粒子。这个比率已测独立的13倍。
The one-charged-particle event is made up of four major modes of decay as well as a collection of other events. The four main types of decay are denoted rho, pi, e and mu. These rates have been measured independently 6, 7, 14 and 19 times respectively. Due to physical constraints each experiment can only estimate the composite one-charged-particle decay rate or the rate of one of the major modes of decay.
一个带电粒子事件是由四个主要的衰变模式以及其他事件的集合。衰变的四个主要类型表示RHO，PI，e和亩。这些利率已经独立的测量6，7，14和19倍，分别。由于物理限制，每次实验只能估计复合一带电粒子衰变率或率衰减的主要交通工具之一。
Each experiment consists of a major research project involving many years work. One of the goals of the experiments was to estimate the rate of decay due to events other than the four main modes of decay. These are uncertain events and so cannot themselves be observed directly.
每个实验由一个主要的研究项目，涉及工作多年。实验的目标之一是估计由于事件比其他四个主要的衰变模式衰变率。这些都是不确定的事件，所以不能被直接观察。
