英文摘要	In this paper we calculate the number of close binaries formed during the evolution process of a globular cluster core. The globular cluster core is assumed to contain a massive black hole at its center. We show that the central black hole can drive binaries formation in the core and the rate of binaries formation depends on the mass of the black hole at its center. When the mass M of the black hole is between 10(2) M. and 3 x 10(3) M., there will be a few binaries formed. When the mass of the black hole is 4 x 10(3) M. less-than-or-equal-to M less-than-or-equal-to 6 x 10(3) M. the number of binary star formation will suddenly increase with a jump to the maximum value approximately 58. When the mass of the black hole is 7 x 10(3) M. less-than-or-equal-to M less-than-or-equal-to 9 x 10(3) M., the number of binary star will immediately decrease. Whether cluster X-ray is produced mainly by the central black hole or by binaries in the core depends on the mass of the central black hole. Therefore, two cases arise: namely, black hole accretion domination and binaries radiation domination. We do think that we cannot exclude the possibility of the existence of a central black hole even when binary radiation characteristics have been observed in globular cluster X-ray sources.
