Based on the contour integral representation and hypergeometric representation of the complex-order Riemann zeta function, we derive an explicit integral equation for the nontrivial zeros of the Riemann zeta function, and then obtain a refined explicit formula for the prime counting function. We extend this theory to the distribution of twin primes, establishing an explicit formula that incorporates the Hardy–Littlewood constant. Ultimately, we construct a complete explicit formula system for the Hardy Littlewood prime k-tuple conjectures, providing multiple analytic representations of the singular series.These results provide new analytic tools for the study of prime number distribution.
