用P(x)逼近π(x)

Approach π(x) with P(x)

我们已有连续函数逼近法寻求π(x)的表达式,即素数定理。但由于函数类型的差异,这种逼近效果有其内在的缺陷。文中介绍了与π(x)类型相同的P(x),用P(x)逼近π(x)的方法寻找π(x)的准确表达式。

In order to seek the expression formula of π （x）, we have continuous law of approximation of function, it is fixed primly that too. But because of the difference of the function types, this kind of approaching the result has its inherent detect. For this reason, this text come to introduce P（x）, the same type asπ （x）, go method to approach π （x） with P （x）.
