(1)發射光譜 邵家麟(1)很早研究過發射光譜在金屬定量上的應用。他用電弧激發原子的輻射能,用感光片攝取光譜,並由譜線的密度測定試樣中金屬的濃度。 羅氏等(2)研究用光電管舆示波器测量光譜的强度。范氏等(3)對於金屬的光電發射在理諭上有所貢獻。張定釗(4)曾用電弧攝取約含55種元素的混和物的光譜,包括2000-6800A範圍內的波長,並將其放大,製成7.5×80厘米的標準片。片中各線的波長與所代表的元素都逐一標明。凡未知物的
(1) emission spectrum Shao Lin (1) early study of the emission spectra in the quantitative application of the metal. He used the arc to excite the radiation energy of the atom, using the photosensitive plate to pick up the spectrum, and determining the concentration of the metal in the sample from the density of the line. Roche et al. (2) studied the intensity of the optical spectrum measured by a photoelectric sensor. Fan et al. (3) contributed to the photoelectric emission of metals in the encyclical. Zhang Dingzhao (4) The spectrum of a mixture of about 55 elements, including the wavelength in the range of 2000-6800A, has been taken by an arc and enlarged to make a 7.5 x 80 cm standard piece. The wavelength of each line in the film and the elements represented by them are all indicated one by one. Where the unknown
