The mechanical environment is described in the paper and then the environments in three different orbits are proposed , called leo ( low earth orbits ) , meo ( medium earth orbit ) and geo ( geosynchronous earth orbits ) . the influence produced by the atomic oxygen , micrometeorites and debris , ionizing radiation and cold welding under vacuum is presented in the paper . some principles are proposed , which can be as the method to choose materials of the mechanism in space environment 空間環境中力學環境對可動結構的影響直接關系到機構的設計問題,所以本文第四章中岳建如:中文摘要浙江大學博士學位論文20024首先詳細論述了空間環境中的力學環境,然后給出了空間環境的三種軌道環境劃分,及每一種環境影響因素對空間可動結構設計的影響,包括原子氧、離子射線、溫度、微隕石和碎片以及真空冷焊現象等環境因素,提出了材料選擇的原則,為可動結構材料選擇提供了一定的依據。

Before repairing , basing on the actual working condition , concerning the weldability , stress and deformation issues , the scheme of the cold welding technology whose essential being gtaw , low temperature preheating , postweld hammer the welded seam was established 修理前,圍繞兼顧解決焊接性、應力和變形問題,結合實際施工條件制定了以手工鎢極氬弧焊、鎳基焊絲、焊前低溫預熱、焊后錘擊焊縫為要素的冷堆焊工藝。
