We derived a set of analytic rat6 coefficients formulas for dielectronic recombination of He- like ions. By these formulas the dielectronic recombination rate coefficientS may be calculated accurately and rapidly without the necessities of doing full ab initio calculations. As an example, we have calculated the rate coefficients of He-like Si ion, and compared with the explicit calculations made by Karim et al., yielding an excellent agreement.
