双细胞光声信号的有限元分析

为了分析两个相同的细胞在不同距离下光声信号的特性，对细胞及环境进行了有限元分析。创建了不同距离的双细胞模型和相同环境下的单细胞模型，通过双细胞模型，得到了主体细胞在受到不同距离的另一个细胞的影响下，其不同角度的频域声压级曲线。通过单细胞模型，得到了单个细胞未受到影响时，其不同角度的频域声压级曲线。将主体细胞与单细胞频域声压级曲线进行相似度比较。结果表明，在受到不同距离的细胞影响下，主体细胞各角度的频域声压级曲线，存在与单细胞相似度极高的曲线，且距离为26.6微米时，相似度最高。这项研究表明，在两个双凹形红细胞距离适当时，细胞间的光声信号相互影响最小。

Finite element analysis of double cell photoacoustic signals

In order to analyze the characteristics of photoacoustic signals of two identical cells at different distances, finite element analysis was carried out on the cells and the environment. Two cell models with different distances and a single cell model in the same environment are created. Through the two cell model, the frequency domain sound pressure level curves of the main cell at different angles under the influence of another cell with different distances are obtained. Through the single cell model, the frequency domain sound pressure level curves at different angles are obtained when a single cell is not affected. The frequency domain sound pressure level curves of main cells and single cells were compared for similarity. The results show that under the influence of cells at different distances, the frequency domain sound pressure level curves of the main cells at various angles have curves with extremely high similarity to single cells, and the similarity is the highest when the distance is 26.6 microns. This study shows that when the distance between the two biconcave red blood cells is appropriate, the photoacoustic signals between the cells have minimal interaction.
