提出了一种动态卡西米尔效应的路径积分公式。它允许我们研究空腔完美反射（传导）边界在{基本空间和时间}中的任意变形。在频率{endash}波矢量平面上，以线性顺序计算中间真空的力学响应。对于单个波纹板，我们发现在低频时存在质量校正，在高频时存在有效剪切粘度，两者都具有各向异性。对于两块板，{几乎所有频率}的谐振耗散大于腔的最低光学模式。{版权所有}{ital 1997} {ital美国物理学会}
A path integral formulation is developed for the {ital dynamic} Casimir effect. It allows us to study arbitrary deformations in {ital space and time} of the perfectly reflecting (conducting) boundaries of a cavity. The mechanical response of the intervening vacuum is calculated to linear order in the frequency{endash}wave-vector plane. For a single corrugated plate we find a correction to mass at low frequencies, and an effective shear viscosity at high frequencies, both anisotropic. For two plates there is resonant dissipation for {ital all frequencies} greater than the lowest optical mode of the cavity. {copyright} {ital 1997} {ital The American Physical Society}
