我们研究了热K-39玻色气体在宽Feshbach共振下的稳定性，重点是散射长度a超过热波长λ的幺正态。我们测量的一般标度律的粒子损失和加热速率的温度，散射长度，和原子数。在么正性和正a
We study the stability of a thermal K-39 Bose gas across a broad Feshbach resonance, focusing on the unitary regime, where the scattering length a exceeds the thermal wavelength lambda. We measure the general scaling laws relating the particle-loss and heating rates to the temperature, scattering length, and atom number. Both at unitarity and for positive a
