【摘要】 采用在不锈钢样品上用油脂粘贴给定质量的铝粉作为模拟喷射体的方法,对ASAY膜法测量微物质喷射总质量的不确定度进行了初步实验检验。实验结果表明,对于mg/cm2量级的微物质喷射总质量,目前ASAY膜法测量的不确定度可以小于50%。更多还原

【Abstract】 The thin foil Doppler laser interferometry named "ASAY foil method" that can measure the mass of the ejection was described.The measurement accuracy of ASAY foil method had been tested on a predetermined ejection called "Simulated Standard Ejection" that a well defined thin layer of aluminium powder was bond on a polished stainless steel plate by vacuum grease.The experimental results show that the relative uncertainty of mass measured by ASAY foil method is less than 50%.更多还原
