分布无关密度估计算法首先将底层数据的任意分布转换成一中间分布——累计概率分布函数。由于累计概率分布函数的输出在[0，1]之间均匀分布，因此接着对累计概率分布函数的输出随机采样，可以准确估计当前网络中数据的密度分布。

Adopting generalized Jordan block and algebra equivalence transform method, all of the transfer functions at different load points can be transformed to state-space description with time variable. The steady robustness of three different mode of control systems were researched by mathematic analysis. It shows that: for the high order inertia controlled object with the characteristic of nonlinear and time-variable that described by the set of transfer functions, the Luenberger function observer established according to its any algebra equivalence state-space description, if some conditions can be met, there would be a matrix of T with n′n satisfied the Sylvester matrix equation TA- FT=GC.

The key to understanding this recipe lies in the definitions of the translate and maketrans functions in the string module. translate takes a string and replaces each character in it with the corresponding character in the translation table passed in as the second argument, deleting the characters specified in the third argument. maketrans is a utility routine that helps create the translation tables.

理解这一配方的关键，在于string模块中 translate 和 maketrans 函数的定义。translate接收一个字符串，并根据第二个参数中传入的转换表，将字符串中的每一个字符替换为相对应的字符，同时删除掉第三个参数中指定的字符（译者注：当translate作为字符串对象的方法调用时，转换表为第一个参数，第二个参数中指定要删除的字符）。maketrans 是一个用来帮助创建转换表的例程。
