该文件考虑了空间环境对一种特殊材料的特殊影响:纳米结构材料（即具有至少一维尺寸在1？nm至100？nm范围内的结构化物体的材料），并规定了此类过程的数学模拟方法。它强调了应用多尺度模拟方法的必要性，不包括任何有关混凝土材料、航天器结构和设备等要素的特殊细节。本文件概述了将不同空间和时间尺度的计算机模拟方法应用于模拟空间环境影响下纳米结构材料中发生的过程的方法。该文件可作为航天器设计、航天器寿命预测和地面导航的参考文件-基于试验，分析运行期间材料性能的变化。

The document considers peculiarities of the space environment impact on a special kind of materials: nanostructured materials (i.e. materials with structured objects which size in at least one dimension lies within 1 nm to 100 nm) and specifies the methods of mathematical simulation of such processes. It emphasizes the necessity of applying multiscale simulation approach and does not include any special details concerning concrete materials, elements of spacecraft construction and equipment, etc.This document provides the general description of the methodology of applying computer simulation methods which relate to different space and time scales to modelling processes occurring in nanostructured materials under the space environment impact.The document can be applied as a reference document in spacecraft designing, forecasting the spacecraft lifetime, conducting ground-based tests, and analysing changes of material properties during operation.
