摘　　要：提出在分光计上做双棱镜干涉实验的实验方法,并论述了该方法的实验原理,给出了测量光波波长的公式.该方法克服了在光具座上进行实验时的调节难度大、不易测量和测量误差大等问题.A method for biprism interference experiment using spectrometer is proposed. The principle of the method is introduced, the formula for determining the wavelength of light are given in turn. The difficulties of adjusting and measuring and the large system errors on the optical bench are eliminated by the method.
