摘要: 在介绍利用同位素放射性原理测量航空燃油密度的机理及测量系统构成的基础上,针对测量中出现的同位素射线初始强度发生波动对测量结果造成干扰的现象,提出了2种解决方法(测量结果修正方法和双探测器差动测量方法),并从原理上论述了利用这2种方法提高同位素航空燃油测量系统抗干扰性能和测量精度的可行性.Abstract: The aircraft fuel density measuring system by utilizing the radioactive isotope was introduced. A method of correcting the measuring data and a scheme of twin-detectors measuring system were led by efforts to solve the initial intensity fluctuation of the radioactive source in the measuring procedure. Then the principles of these two solutions were discussed in detail.
