natural element ansformer

The way to finish the project by using the same optical potential of natural hf and its isotopes is unpreceded and successful
该工作通过使各同位素与天然元素的光学位一致实现数据自洽的方法在国内外尚属首次，并取得了成功。
Natural resource is defined as under certain technical and economic conditions , all natural elements existing in the natural world which are useful for human beings ， such as land , water , forest , meadow , wildlife and wild plant
自然的资源被定义为在某种技术和经济的条件下，所有存在于自然世界的天然元素对人类都是有用的，如陆地，水，森林，草地，野生动物和野生植物。
It includes three steps : first , the experimental data in exfor format is evaluated . then , the optical potential parameters are got by using the code apom94 , and the direct inelastic discrete energy level reaction cross sections and angular distribution of every isotopes are got by using the code dppm . thus the ultimate commended data , which coincide with each other , can be obtained by using code nunf
其具体过程是先对exfor实验数据进行评价，给出实验数据评价值，然后，利用程序apom94计算光学位，利用dppm程序计算直接非弹分立能级反应截面和角分布，在此基础上，利用nunf理论计算程序获得各同位素本身数据以及各同位素与天然元素数据自洽的最终推荐值。
