从太阳神1号的数据进行检查，以找到一个实验适合的T（V）关系在1 Au。数据显示质子温度-速度斜率在V = 500 km s−1处有明显的变化。对于V > 500 km s−1，T =（0.77±0.021）V -（265±12.5），而对于V < 500 km s−1，T1/2 =（0.031 ± 0.002）V -（4.39±0.08）或T1/3 =（0.0106±0.001）V -（0.278±0.03）。这些结果与Burlaga和Ogilvie（1973）的结果进行了比较，在V < 500 km s−1的范围内，结果非常一致。此外，还考察了T（V）的长期变化，发现上述函数形式对于接近太阳极小期的2年间隔和接近太阳极大期的2年间隔仍有很好的拟合。
Data from Helios 1 are examined to find an experimental fit for the T(V) relationship at 1 AU. The data show a distinct change in the proton temperature-velocity slope at V ∼ 500 km s−1. For V > 500 km s−1, T = (0.77±0.021)V - (265±12.5), while for V < 500 km s−1, T1/2 = (0.031 ± 0.002)V - (4.39±0.08) or T1/3 = (0.0106±0.001)V - (0.278±0.03). These results are compared to the results of Burlaga and Ogilvie (1973) and show excellent agreement in the V < 500 km s−1 range. In addition, the secular variation of T(V) is examined, and it is found that the above functional forms still provide a good fit for a 2-year interval approaching solar minimum and a 2-year interval approaching solar maximum.
