介绍了云台太阳光谱望远镜光栅鬼线强度测量方法。给出了２ 级光谱罗兰鬼线强度的初步测量结果， 为母线强度的０ ．０４９ ％ 。结果表明光栅的质量优良， 鬼线对光谱测量的影响非常小， 一般情况下在光谱资料处理中可以不必考虑鬼线强度的改正
The ghost line intensity measurement method of the PTZ solar telescope grating is introduced. A preliminary measurement result of the intensity of the 2-step spectrum Roland’s ghost line is given as 0 for the bus strength. 049%. The results show that the quality of the grating is good, and the influence of the ghost line on the spectrum measurement is very small. In general, it is not necessary to consider the correction of the ghost line intensity in the spectral data processing
