Increasing evidence supports the hypothesis of autologous immune attack in severe aplastic anemia(SAA):the predominant role of activated cytotoxic T cells(CTL)expressing-interferon in inhibiting the growth of bone marrow(BM)cells,putative autoantigens,and oligoclonal expansion of CD8+T cells.1 For SAA patients,the definitive therapies are immunosuppressive therapy(IST)or hematopoietic stem transplantation(HSCT).

Fast prediction method of full-space bistatic scattering sound field of underwater stiffened double cylindrical shell

引用

Chinese Journal of Acoustics 2024年第2期43卷 155-172页

作者： chen Changxiong PENG Zilong SONG Hao FAN Jun XUE Yaqiang School of Energy and Power Engineering Jiangsu University of Science and TechnologyZhenjiang 212100 Systems Engineering Research Institute Beijing100094 State Key Laboratory of Ocean Engineering Shanghai Jiao Tong UniversityShanghai 200240

A fast prediction method is presented for the full-space bistatic scattering sound field of the underwater stiffened double cylindrical shell. The scattering sound field is represented as the product of the acoustic scattering transfer function and the sound source density function. The target surface grid information and a small amount of simulation or experimentation multistatic scattering sound pressure data are used as known information to forecast other bistatic scattering sound fields with the help of numerical integration, matrix theory, and least squares method. The scattered sound pressure data from simulation of the finite element method(FEM) and experimental tests are used as input to calculate the multistatic scattered sound field of the underwater stiffened double cylindrical shell, respectively. The calculated results are compared with those calculated exclusively by the FEM, and the effects of different input data and calculation frequencies on the calculation results are discussed. The results show that the proposed method can predict the full-space bistatic scattered sound field of the target when the surface structure and part of the scattered sound field data are known. The greater amount of known scattered sound pressure data and lower computational frequency lead to higher predicted accuracy.
