- 在理论分析的基础上,着重采用Fox-Li数值迭代法计算了平平腔振荡模式的振幅分布和相位分布。计算结果表明,在经过300 次渡越后,归一化的振幅分布和相位分布实际上已不再发生变化,镜面中心处振幅最大，从中心到边缘振幅逐渐降落，镜面已不再是等相位面了。但对于菲涅尔数较大的平行平面腔，特别是在镜面中心及其附近，平面波是很好的近似，只有在镜的边缘处，波前才发生弯曲。则已找到光腔的一个自再现模式或横模分布。另一方面,分析了腔镜倾斜扰动对平平强腔内振荡模式的影响。数值计算表明,腔镜倾斜破坏了场分布的对称性,

fit_maxwell_pdf
- 麦克斯韦-玻尔兹曼分布是一个概率分布，在物理学和化学中有应用。最常见的应用是统计力学的领域。任何（宏观）物理系统的温度都是组成该系统的分子和原子的运动的结果。这些粒子有一个不同速度的范围，而任何单个粒子的速度都因与其它粒子的碰撞而不断变化。然而，对于大量粒子来说，处于一个特定的速度范围的粒子所占的比例却几乎不变，如果系统处于或接近处于平衡。麦克斯韦-玻尔兹曼分布具体说明了这个比例，对于任何速度范围，作为系统的温度的函数。它以詹姆斯·克拉克·麦克斯韦和路德维希·玻尔兹曼命名。-Maxwell- B
