The basic theory of temporal mechanical fluctuation induced systematic errors in Casimir force experiments is developed and applications of this theory to several experiments is reviewed. This class of systematic error enters in a manner similar to the usual surface roughness correction, but unlike the treatment of surface roughness for which an exact result requires an electromagnetic mode analysis, time dependent fluctuations can be treated exactly, assuming the fluctuation times are much longer than the zero point and thermal fluctuation correlation times of the electromagnetic field between the plates. An experimental method for measuring absolute distance with high bandwidth is also described and measurement data presented.
阐述了在卡西米尔力实验中由时间机械波动引起系统误差的基本理论，并回顾了该理论在几个实验中的应用。这类系统误差的产生方式类似于通常的表面粗糙度校正，但与表面粗糙度处理不同，表面粗糙度校正的精确结果需要进行电磁模式分析，而对于时间相关波动，假设波动时间远长于平板间电磁场的零点和热波动相关时间，则可以精确处理。还描述了一种用于高带宽测量绝对距离的实验方法并给出了测量数据。
