This paper discusses some application cases of the error propagation law by the examples of trigonometrical survey, and presents that not only sum function and numeral multipling function in which there is only one independent observed value but also more complex functions which are equal in mathematics are not opposite in the process of error propagation according to the error propagation law.

1引言本文以三角测量为例，对误差传播定律一些应用问题进行了讨论，指出当只有一个独立的观测值时，和函数与倍数函数运用误差传播定律不会出现悖论；如果在测量工作中有多余的直接观测值，就需用平差后的间接观测值按协方差传播律来计算，这样数学中相等的函数关系才能得到同样的函

This repetition of Four at the most rudimentary level led me to wonder why each college had only 5 spells. Should they not have 4, or unthinkably 16?

大部分基本元素都是四的倍数，所以我十分想知道为什么每所学院里只有5种魔法，为什么不是4种，甚至是16种？

It should be noted that the characteristics of this engineering model confused not only us, but also people, which have precise idea about processors Conroe- L. What wasat least the maximum multiplier of those cpu, which gives the total frequency of 2.8 GHz.

应当指出的特点，这个工程模型的混乱，不仅我们自己，也是人，其中有精确的了解处理器conroe-油菜是什么，至少倍数最高的cpu，它给人的总次数为2.8千兆赫。
