The MARS code is under continuous development and has recently undergone substantial improvements that further increase its reliability and predictive power in numerous shielding, accelerator, detector and space applications. The major developments and new features of the MARS15 (2004) version described in this paper concern an extended list of elementary particles and arbitrary heavy ions and their interaction cross sections, inclusive and exclusive nuclear event generators, module for modelling particle electromagnetic interactions, enhanced geometry and histogramming options, improved MAD-MARS Beam Line Builder, enhanced graphical user interface and an MPI-based parallelisation of the code.
MARS代码正在持续开发中，最近经历了重大改进，在众多屏蔽、加速器、探测器和空间应用中进一步提高了其可靠性和预测能力。本文所述的MARS15（2004）版本的主要进展和新特性包括：扩展的基本粒子和任意重离子列表及其相互作用截面、包含和不包含核事件发生器、用于模拟粒子电磁相互作用的模块、增强的几何和直方图选项、改进的MAD-MARS束线生成器、增强的图形用户界面以及基于MPI的代码并行化。
