摘要：
This paper reports a method for determining the internal pressures of ampoules, from the head space and the change in volume on opening, as measured by displacement of water. Using this method, internal pressures of commercial ampoules were shown to be lower than atmospheric pressure. For example, the ratio of internal pressure to atmospheric pressure in a commercial ampoule of 5 mL distilled water was 0.884 at room temperature (23-degrees-C).
