It is found that the thermal fluctuation level of the shear-Alfv&#233;n waves in a gyrokinetic plasma decreases with plasma <font face = "symbol">b</font> (is identical to c<sub>s</sub><sup>2</sup>&#47;<font face = "symbol">u</font><sub>A</sub><sup>2</sup>), where c<sub>s</sub> is the ion acoustic speed and <font face = "symbol">u</font><sub>A</sub> is the Alfv&#233;n velocity. This unique thermodynamic property based on the fluctuation-dissipation theorem is verified in this paper using a new gyrokinetic particle simulation scheme, which splits the particle distribution function into the equilibrium part as well as the adiabatic and nonadiabatic parts.
