求翻译：通过离散元二次开发，编写了描述颗粒形状的fish子程序，该子程序可以把储存的信息还原为颗粒形状，利用材料参数赋值功能将细观参数分别赋予模拟体中的颗粒填料、水、气体。依据分形几何多尺度间的相似性理论，将由核磁共振试件生成的颗粒模拟作为一个含水路堤土单元，多个这样的单元组成了本文分析的宏观路堤（图2）是什么意思？

Prepared to describe the particle shape by discrete element of the secondary development of fish subroutine, the subroutine can restore the information stored in the particle shape, material parameter assignment function of the micro-parameters were given to the packing of particles in the simulatio

At $2 with discrete development, preparing a description of the particle shape fish sub-program, the program can restore the information stored in the particle shape parameters, and use of materials that will function fine, parameters are given in the simulated particle packing, water and gas. Based

Through a separate Yuan re-development, has compiled the description grain shape fish subroutine, this subroutine may return to original state the storage information into the grain shape, will view carefully the parameter using the material parameter evaluation function separately to entrust with s

Through the secondary development of discrete element, write a description of particle shape fish program, the program can restore the information store to particle shape, use material parameter assignment function to mesoscopic parameters respectively given simulation of particulate fillers, water,
