absorbtivity

We have calculated a series of thyroid s absorbed dose rate when the γ ray which was generated from the warhead penetrated the various depths of the lead glass via the model.

以甲状腺为研究对象,应用蒙特卡罗方法通用软件MCNP4B程序建立模型,模拟计算了操作人员在操作核弹头时,弹头中产生的γ射线透过各种厚度的铅玻璃时人体甲状腺吸收剂量率。

The absorbed dose rates from 10B(n,a)7Li,14N(n,p)14C,1H(n,r)2D and fast neutron elastic scattering reaction are considered.

吸收剂量率主要来自以下四个反应:~(10)B(n,α)~7Li,~(14)N(n,p)~(14)C,~1H(n,γ)~2D,快中子弹性散射反应。

Neutron and γ-ray absorbed dose rate in the air at 1 m distance from the source were calculated with the results of 1.

cm2,距离该源1 m处空气对中子和γ射线的吸收剂量率分别为1。

Then the basic science problem connected with materials ballistic performance closely such as dynamic strength,absorbed energy rate,adiabatic shear deformation localization and dynamic hardness are discussed primarily.

介绍了高应变率载荷条件下镁合金的吸能特性及变形特征;论述了对镁合金抗弹性能有重要影响的动态强度、高应变率能量吸收率、高应变率变形断裂特征和动态强度等科学问题;就镁合金在装甲领域的应用研究做了初步探讨。
