Properties and Modification of Bismuth-Layered Structure Ferroelectric Materials and Application in Sports

Abstract

Bismuth-layered oxides are a very important class of ferroelectric materials. Due to their special structure, they have outstanding features in many aspects, such as high Curie temperature, large spontaneous polarization, polarization stability to temperature, high voltage resistance, low dielectric loss, and excellence. Due to its antifatigue properties, the system is very suitable for applications in nonvolatile random access memory and high-temperature sensors. The purpose of this paper is to study the application of the performance and modification of bismuth-layered ferroelectric materials in sports scientific research. Proposed the combination of new materials and sports scientific research projects. This article uses sample analysis and (the comparative experiment method is a method to compare the experimental group and the control group to illustrate the superiority of the experiment) comparative experiment methods, sets up an experimental group and a control group, summarizes the algorithm rules through the study of the microscopic properties of nanomaterials, and designs a numerical simulation program. The experimental results in this article show that after receiving hyperbaric oxygen recovery in the first week, the heart rate of the experimental group subjects has a significant change, which is significantly lower than the initial value ( $p<0.05$ ), from 58.0 to 53.0, The higher pressure oxygen had a very significant drop before recovery, from 62.9 to 53.0. In the second week and the third week, the heart rate index decreased significantly after 1 hour of hyperbaric oxygen recovery ( $p<0.01$ ), from 54.3 to 49.3 and 56.1 to 52.4, respectively. After the fourth week of intensity training, the heart rate increased significantly from the initial value ( $p<0.05$ ), from 49.6 to 55.2. After 1 hour of hyperbaric oxygen recovery, there was a significant decrease compared with before the hyperbaric oxygen recovery ( $p<0.05$ ), dropped from 55.2 to 53.1. Illustrate the success of the experimental results. It also completed the subject of interaction and combination of the performance and modification of bismuth-layered ferroelectric materials in sports scientific research.
