it is obtained by numerical calculation that the mode spot size at the mirrors in a resonator with arbitrary configuration is always a finite value as long as radial gain variations are present.
只要出现径向增益变化,通过数值计算得到任意结构的谐振腔腔镜处的光斑尺寸总是有限值。
therefore the velocity and the atmospheric equivalent height are of the finite value distributions and they change with time.
其中速度、大气自由面的高度均为有限值分布且随时间变化。
based on characteristic set, the case of infinity parameters is described by using of finite value and functions.
在特征集的基础上,讨论了其参数导数的构成情况,用有限个点和函数表示了无穷个参数导数的情形。
the superconducting transition temperature is the point at which a material's resistance changes from a finite value to zero.
