Based on the data observed from 1960 to 1962 in the middle region of the Yellow River, the experimental formula of the acts (1)is verified, we find that this formula is capable to be used in our studied region, and so the annual and monthly tatol radia-tion of the 61 stations is calculated. Following a simple analysis of this result, we obtain the principal fallowing conclusions: 1. The straight radiation, being beyond per 500}o plays a principal role in the tatol radiation. 2. The annual tatol radiation is about 110-150 kcal/cm2. The maximum of an-nual variation occuss in June, and the minimum in December. 3. Both the annual variation and the diurnal variation of the radiation in the north-western part of the region are larger than those in the southeastern part.4. The annual radiation balance is (39-48 kcal/cm2)，which in less than the an-nual radiation balance in the places of the same latitude.
