Fourier
/ˈfʊərɪeɪ,〈法〉 fuʀje/- Fourier, Jean Baptiste Joseph (1768-1830), French mathematician. His studies involved him in the solution of partial differential equations by the method of separation of variables and superposition; this led him to analyse the series and integrals that are now known by his name.傅里叶, 让·巴蒂斯特·约瑟夫（1768-1830, 法国数学家, 研究用变量分离和叠加方法解偏微分方程, 并用以分析级数和积分; 此级数和积分如今以他的名字命名）。
