| 中文摘要: |
| 目前国内对于面向学生实验用核测量仪器都为单一的测量物体密度、厚度或料位的实验装置，并且在源强的选择上大都在10 mCi左右.本设计针对此情况，提出了一种优化设计方案.该设计方案对放射源源强的选择，密封源的结构设计，被测物质的选择等进行了理论模型估算，以得到一优化方案.该方案采用活度为1 mCi的放射源137Cs 以减小照射剂量，并且在测量功能上进行了改进，使仪器集测量密度、厚度、料位这三种功能于一体. |

| So far domestic student-oriented experimental nuclear measuring instruments are used only to measure object density, thickness or material level, and in the choice of sources activity is mostly about 10 mCi. This design will proposed a optimization program dealing with domestic situation. It discussed the radioactive sources activity, the structural design of sealed sources, such as the choice of the tested material in order to get a program optimization. The program used 1 mCi activity radioactive sources 137Cs to reduce the radiation dose, and the measurement function was improved .So that the apparatus can measure density, thickness and material level. |
