摘　　要：研究设计了以解析吸收片后的透射率来测量快脉冲硬X射线辐射场能谱的实验方法。对实验方案进行了理论模拟设计,并获得了解谱必要的理论数据,通过测量不同吸收片后光强的实验方法获得了透射系数,用微扰的数学方法完成了测量谱的解析,复现了测量位置处快脉冲硬X射线辐射场能谱,最后对该方法的可靠性进行了验证。The experimental method was built by transmission coefficient analysis to measure spectrum of narrow pulsed hard X-ray. The theoretical design of experiment plan was done and the data for spectrum unscrambling were obtained by simulation. The transmission coefficient was determined by measuring light intensity after attenuator, unfolded by the mathematical method of infinitesimal disturbance. The relative spectrum was reconstructed, and its reliability was validated.
