Description
该节中阿姆德尔定律wiki上译为阿姆达尔定律，翻译中该定律公式太简单了，并且译中：例如一个程序90%的代码都是并行的，但仍存在10%的串行代码，那么系统中即使由无限个处理器能达到的最大加速比仍为9
计算错误，不应该是9，应该是10，套用阿姆达尔定律：s=1/[1/10+(9/10)/p];p趋于∞，s=10.

Research direction
Search the repository for section 6.4, “阿姆德尔定律,” and inspect the translated wording and formula. Verify the Amdahl's law calculation for 90% parallel and 10% serial code, then update the terminology and explanation so the limiting speedup is stated as 10.
