查询词典 Monte Carlo

On the basis of atomic transition enerygy and absorbed bounds, a filter of the same ingredient as target material was adopted. This method can make the original polychrome X-ray turn into almost homochrome. Simulation analysis was taken by Egsnrc software based on Monte Carlo method and good effect gained.

文章摘要：目的以153Sm-乙二胺四甲撑膦酸（153Sm-EDTMP）治疗鼻咽癌多发性骨转移为例，分别用蒙特卡罗法（Monte Carlo，MC）和MIRD方法计算153Sm-EDTMP治疗后病灶和骨髓等靶器官的吸收剂量，探讨其临床应用之不同。

Key words: Monte Carlo method; MIRD method; ^153Sm-EDTMP; Absorption dose

患者注射153Sm-EDTMP 33.6×37 MBq，左髂骨转移病灶最高吸收剂量约为5.6 Gy，病灶边缘的吸收剂量为2.0 Gy，以病灶区最高剂量点为参考点，则椎体、皮质、骨髓、脊髓和盆腔组织仅相当于最高剂量的37%、12%、13%、21%和2%；MIRD方法的计算数据仅能粗略提示全身红骨髓吸收剂量，为2.39 Gy。

With Protosalanx hyalocranius,Coilia nasus and Salangichthys tangkahkeii as test objects,a food web model of main economic fishes in Taihu Lake was established,with which,the distribution characteristics of DDT in the benthos,zooplankton and fishes of the food web were studied by Monte Carlo simulation method,and one-hit model was used to approach the ecological risk of the DDT distribution.
