关于Lambert W（x）函数
Having Fun with Lambert W(x) Function
摘要：
这篇短文介绍了朗伯W（x）函数及其在皮埃尔俄歇天文台相关物理框架中的可能应用。在C++中的实际数值实现包括Halley和Fritsch迭代，分支点展开，渐近级数和有理拟合作为初始近似。
英文摘要：
This short note presents the Lambert W(x) function and its possible application in the framework of physics related to the Pierre Auger Observatory. The actual numerical implementation in C++ consists of Halley's and Fritsch's iteration with branch-point expansion, asymptotic series and rational fits as initial approximations.
