例句與造句

1. the photon spectrum data that are used in the calculation for translating the absorbed dose to the photon fluence have been obtained by the experimental method with a 12mv pulse accelerator and the iterative least-squares data analysis technique
   為此，利用穿透系數(shù)數(shù)值分析的疊代最小二乘法對12mv脈沖加速器的軔致輻射譜進行了實驗測定，并在同樣的幾何條件下，用m-c方法對其進行了計算。
2. the let factors rlet ( rlet = 0.05 ) of neutron response for liftld in various n + y mixed fields in the fast neutron reactor have been determined experimentally due to the existing let effects of the response for liftld to neutron absorbed dose . the experimental results show that the let factor for neutrons from thermal energy to 5mev energy is about 0.050 . so it is workable to measure the photon fluence in the pulse reactor with 7liftld
   為確定liftld能否用于n、混合場的區(qū)分測量，本文定義了let效應因子，并對liftld的let效應因子進行了實驗測定，測量結(jié)果表明：liftld對熱中子至5mev中子響應的let效應因子值約為0.050，因此，選用~7liftld用于脈沖堆光子注量測量是可行的。
3. it proves that the accuracy of the obtained photon fluence by this kind of method is acceptable . overall, pulse photon fluences in the pulse accelerator and the radiation field caused by pulse reactor have been obtained by strict experimental studies and theoretical calculation in this paper . it provides the technological support to calibration of detectors for physical diagnosis in nuclear exploding
   簡而言之，通過嚴格的實驗研究和理論計算，本文測得了12mv脈沖加速器的x射線譜和liftld對較寬能區(qū)的中子的let效應因子值，并通過研制的均勻固體電離室測得了脈沖加速器和脈沖堆輻射場的光子注量，解決了幾個相關的技術難題，為核爆診斷探測器的標定提供了技術支撐。
4. It's difficult to find photon fluence in a sentence. 用photon fluence造句挺難的
