However, studies on its optical spectra, including excitonic effects, are very limited for this material.
Since the discovery of topological behavior in three-dimensional materials, Bi2Se3 has been considered as the best model for the study of topological surface states [1, 2].
Experimental studies have shown that Bi2Se3 is a semiconductor material with small band gap around 0.14 - 0.56 eV [3-5].

The Cr and Ni content of these materials are high, while the carbon content is controlled within the range of ultra-low.
These materials have better corrosion resistance, but they are of low hardness, which results in poor wear resistance [5-7].
These traditional materials can no longer meet the needs of production development.

However, as a kind of non-metal polymer materials, PMMA is still more fragile compared with metal materials, which could craze and crack under stresses due to load and temperature.
The testing platform is made of heat-resistance and pressure-resistance stainless steel materials, used to install porthole assembly and temperature, pressure, displacement sensors.

Once there is a breakdown in a complex hydraulic system, it will consume manpower and material resources because of cumbersome investigation, and the efficiency is low.
Noise can be reduced by using more insulation materials.
