The study of "basic" particles requires extremely high energy. To understand the microstructure of matter, you must first change the microstructure, and you must first change the microscopic matter. Shattered, exposing their internal structure and various properties. What is the correct interpretation of the "microstructure of matter" and "microscopic matter"? ['Both reflect the structure of microscopic matter, i. e. the microstructure constitutes the microscopic matter.', 'The former refers to the atomic structure (including the nucleus), while the latter refers to small particles such as protons and neutrons.', 'The former refers to the combined mode inside small particles, and the latter refers to the various small particles that make up matter.', 'Both refer to the molecules, atoms, protons, neutrons and other particles that make up the substance.']
