质量管理体系中的计量保证工作研究

计量保证是型号产品质量管理的重要组成，是保证型号研制、生产、试验、使用中单位统一、量值准确可靠的重要手段，为支撑型号创新发展和保证型号产品质量发挥着基础性保障性作用。经过多年发展，计量保证已逐步融入型号质量工作，并通过质量管理条例、计量监督管理条例等相关法规和标准得到进一步的巩固，有力地支撑着型号的研制生产。新时期，型号产品发展为计量保证工作提出了新要求、新问题和新挑战，本文对型号计量保证工作的现状、发展需求和存在的不足进行了分析，并提出了后续的工作建议。

Experimental Research on Phase Characteristics of High-power-microwave Phase Measurement Channel with Different Excitation Power

This paper studies the influence of signal power on the phase measurement in high power microwave. Presents phase delay characteristic measurement of the phase delay characteristics under dif-ferent excitation power states from mW to kW power level. Measuring system consists of high-power-mi-crowave pulse source, directional couplers groups. Attenuators which are widely used in high-power-mi-crowave phase measurement system were measured. Measurement results show that in 1kW power range, phase delay of those typical devices varies within ＆#177;2o, the phase delay characteristics can be considered with no changes for the different excitation power.
