为在荧光检测时科学、合理地使用高强度紫外线，做了大量的荧光磁粉检测试验，得出紫外线辐照度u与白光照度v的对应关系曲线，并通过线性拟合得到了对应关系公式。研究结论在大量现场试验中得到了证实，填补了现行标准在荧光磁粉检测工艺方面的空白，具有重要意义。

In order to use high ultraviolet light intensity more reasonably, by conducting fluorescent magnetic powder test(MPT) experiments, the relationship of ultraviolet light intensity to white light intensity was deduced and showed in the u-v curve, and by linear approximation to the u-v curve, the corresponding formula was acquired to describe the relationship. The research conclusion was proved to be scientific in a large amount of local tests, which filled a blank in fluorescent MPT technique.
