本文表明，流体加载的校正必须进行基于地球的校准行星探测器传感器，这依赖于准确和精确的预测机械振动。这些传感器包括声学仪器和用于由振荡板上的物质积累引起的质量变化的传感器。一些已发表的设计特别容易受到影响（显示了导致金星频率校准中的倍频程误差的示例）。由于这种修正以前没有提出，将几乎不可能纳入下降测试的探头，本文证明了令人惊讶的结果，应用完善的配方。
This paper shows that corrections for fluid loading must be undertaken to Earth-based calibrations for planetary probe sensors, which rely on accurate and precise predictions of mechanical vibrations. These sensors include acoustical instrumentation, and sensors for the mass change resulting from species accumulation upon oscillating plates. Some published designs are particularly susceptible (an example leading to around an octave error in the frequency calibration for Venus is shown). Because such corrections have not previously been raised, and would be almost impossible to incorporate into drop tests of probes, this paper demonstrates the surprising results of applying well-established formulations.
