Annual Average Growth Rate two methods for calculating annual average growth rate are applied in China, one is often called "level approach" or the method of calculating geometric average, which is derived by comparing the level of the last year of the interval with that of the beginning year; the other is called "accumulative approach" or algebraic average or equation method, which is derived by the summation of the actual figure of each year in the interval divided by the figure in the base year.

平均增长速度我国计算平均增长速度有两种方法：一种是习惯上经常使用的"水平法"，又称几何平均法，是以间隔期最后一年的水平同基期水平对比来计算平均每年增长速度；另一种是"累计法"，又称代数平均法或方程法，是以间隔期内各年水平的总和同基期水平对比来计算平均每年增长速度。

In Chapter 3, we consider the semi-direct product AG, and analyze the decomposition in AG of idempotents of AH, and obtain a precise algebraic description; as a corollary, we show a criterion of the primitivity in AG of a primitive idempotent of AH, hence a theorem of Fong and a theorem of Green are generalized to an uniform setting.

考虑半直积AG，我们分析了AH的幂等元在AG中的分解模式，得到了一个准确的代数刻画；作为它的推论，给出了AH的本原幂等元在AG中仍然本原的判断准则，从而将Fong的定理和Green的定理推广到了一个统一的情形。
