摘　　要：The chirality-asymmetry macroscopic force mediated by light pseudoscalar particles between a-quartz and some achiral matter is studied. If this force between achiral source mass and a-quartz with some chirality is attractive, it will become repulsive when the chirality of the a-quartz crystal is changed. According to the tested limits of the coupling constant gsgp/hc 〈 1.5×10^-24 at the Compton wavelength A = 10-3 m, the force （F） between a 0.08 × 0.08 × 0.002 m3 block of a-quartz and a 0.08 × 0.08× 0.01 m3 copper block with a separation being 0.5 × 10^-3 m in between, is estimated from the published data at less than 4.64 × 10^-24 N, i.e. F 〈 4.64 ×10^-24 N.The chirality-asymmetry macroscopic force mediated by light pseudoscalar particles between a-quartz and some achiral matter is studied.
