Examples
- The structure and energy level of the al clusters include 2 atoms to to 7atoms was calculated with ab initio method . discrete energy levels were found in the clusters , which is different from the energy level distribution of bulk materials
计算方法是采用gaussia98程序的b3lyp的方法和全电子的基函数6 - 311 + g * ，对al2 ? al7小团簇的结构和能级进行了abinitio计算。 - 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。 - Drawing the following concludes : ( 1 ) for the different metallic small particles with even number or odd number , the heat capacity is varied . the result is different from the bulk metal in essence . at the low temperature , the distribution of the discrete energy levels has important effects on the heat capacity ; at the high temperature , the distribution of the discrete energy levels has little effects because of the involving of mass electrons into the energy distribution
得到如下结论： ( 1 )金属小粒子所含的电子数奇偶性不同，其电子热容是不同的，这与大块金属有本质区别；低温极限时电子热容受能级分布的影响很大；而在高温时，有大量的电子参与能量配位，比热遵循大块金属的线性规律，能级分布的影响小时。 - In this thesis , we demonstrate the study of si - based light emitting materials and its importance in si - based photonics integration . we discussed mainly the gain , differential gain , threshold current of si - based quantum - dot laser and the dependence of threshold current on temperature from discrete energy level of three - dimension confined quantum - dot and state density distribution of 5 - function
