文章导出一种由两个中性的惰性气体原子之间的碰撞引起的电四极辐射几率。对于热平衡的惰性气体系统,推导出由碰撞引起的总辐射能量的公式(单位体积,在给定波长的每单位波长)。考虑到气体的吸收和周围环境水的折射,用此公式拟合纯氙和纯氪的单气泡声致发光的实验光谱,拟合温度大约为 5,000k,结果令人满意。
文章導齣一種由兩箇中性的惰性氣體原子之間的踫撞引起的電四極輻射幾率。對于熱平衡的惰性氣體繫統,推導齣由踫撞引起的總輻射能量的公式(單位體積,在給定波長的每單位波長)。攷慮到氣體的吸收和週圍環境水的摺射,用此公式擬閤純氙和純氪的單氣泡聲緻髮光的實驗光譜,擬閤溫度大約為 5,000k,結果令人滿意。

We educe a probability of the electric quadrupole emission of a photon induced by collision between two neutral atoms of inert gases. For heat equilibrium system of inert gas, we deduce the formula of the collision-induced total radiation power per unit volume, per unit wavelength at the given wavelength. Considering the absorption of the gas and refraction of surrounding water, the formula apply to fit the experimental spetra of sonoluminescent pure xenon and pure krypton bubbles, the fits are shown to be quite well correspond to temperature about 5,000K. The good agreement obtained demonstrate the new light-emitting mechanism of sonoluminescence of xenon and krypton bubble.
