"In the rapid development process of our country

our economy is growing rapidly and society is constantly progressing. With the advancement of materials science

some very useful new materials have emerged

including optical fibers

shape memory alloys

and amorphous substances. In addition to the rapid progress in materials science

users have also put forward more stringent requirements for material performance and external conditions. Various materials are widely used in precision machinery and measuring instruments. These materials are still under development

promoting scientific progress while improving usability. Firstly

precise measurement techniques for mechanical properties are introduced

followed by an in-depth exploration of their practical applications to facilitate the development of measurement work."
