对得到的无定形体系结构用蒙特卡洛（Monte Carlo）和主方程模拟计算了电子和空穴迁移率。计算结果表明，UFF力场模拟得到的结构，没有考虑极化的位点能，两种计算方法都是空穴迁移率比电子迁移率大；考虑极化的位点能，电子迁移率比空穴大，且迁移率随电场的增大而增大，符合Poole-Frenkel行为。Dreiding力场模拟得到的结构，没有考虑位点能极化时，两种计算方法都是空穴迁移率和电子迁移率相当；考虑位点能极化后，空穴迁移率大于电子迁移率，原因是空穴转移积分大于电子转移积分（耦合强），可能是电子陷阱太深，说明堆积方式是决定物质载流子传输能力的关键因素。随后我们又考虑了动态的电荷转移积分随时间（1ps，10ps和100ps）变化，短时间1ps和长时间100ps变化趋势是一样的，所以可以用短时间的电荷转移积分来预测长时间的电荷转移积分。 To get the system structure of amorphous with Monte Carlo (Monte Carlo) and the simulation calculation master equation of electronic and hole transfer mobility. The calculation results show that the structure of the simulations are UFF, no account of the polarization of the loci can, two kinds of calculation methods are hole mobility than electronic transfer mobility; Consider the polarization of the sites, electron mobility than hole of big, and with the increase of the electric field mobility and increase, accord with Poole-Frenkel behavior. Dreiding force field of the structure of the simulations are, without considering sites can polarization, two kinds of calculation methods are hole mobility and the electronic transfer rate quite; Consider sites can polarization, hole mobility than electronic transfer, the reason is greater than the electronic transfer of hole transfer (coupling strong), may be electronic trap too deep, explain accumulation way is the ability of the transmission carriers determine physical key factors. Then we have considered the dynamic charge transfer over time (1 ps, 10 ps and 100 ps) change, the short time 1 ps and long time 100 ps change trend is the same, so can use the short time to charge transfer to predict long charge transfer. 麻烦修改一下翻译的英文语句，非常感谢！ |

| An analog computation of charges and holes mobility is carried out based on the structure of amorphous system by Monte Carlo and master equation. The conclusion shows that mobility of holes is higher than charges by these two methods without the consideration of polarized locus energy in the structure of UFF force field analog. However, mobility of charges following the increase of electric field will be higher than holes if we take polarized locus energy into consideration. This fits the behavior of Poole-Frenkel. In the structure of Dreiding force field analog, the mobility is equal by two methods without polarized locus energy. If considerate, mobility of holes is higher than charges which may be the reason of a higher transfer integration of holes than charges (stronger coupling) with a deeper electron trap. This means that accumulation may be the key point of ensuring the transmittability of substance carriers. Soon after that we conclude that there’s nothing different among variation tendency of dynamic transfer integration of charges from 1ps to 100ps. So we can calculate long-term transfer integration of charges by the short-term. |
