求翻译：很多情况下，由于所应用的材料在相当恶劣的使役环境中承受着各种检验，其硬度、抗震性、抗断裂能力、强度、膨胀性都面临着严峻的挑战，而检验这些性能都跟材料在对应环境中的变形程度密切相关，而变形由于材料的应变直接相关是什么意思？

With the continuous upgrading of the spacecraft, the continuous improvement of its performance, continuously improve the mechanical performance requirements of relevant materials

In many cases, because of the material that is applied in a bad environment to bondage in the various tests, its hardness, shock resistant, anti-breakage capacity, strength, swelling of the face with a daunting challenge, and the test material with all the performance in the corresponding environmen

In very many situations, because applies the material in quite bad causes in the service environment to withstand each kind of examination, its degree of hardness, the anti-knocking property, anti-break ability, the intensity, the expansibility all are facing the stern challenge, but examines these

In many cases, due to the application of material under inspection in a poor work environment, its hardness, seismic, breaking capacity, strength, swelling face severe challenges and performance testing of the material in the corresponding reduction in the environment is closely related to, and dire
