【摘要】 第19太阳周内6．5年中的1119个≥2-级太阳耀斑，相对于木星和金星的日面经度观测分布为Pj（L）和Pv（L）．五种理论分布假设为：（1）均匀随机分布；（2)均匀随机十横向潮汐力分布；（3）均匀随机十竖向潮汐力分布；（4）均匀随机十潮汐力模量分布；（5）均匀随机十横向潮汐力和竖向潮汐力分布．观测和理论分布的X2拟合优度检验表明：在较严格的显著性水平上（α＜0.01），五种理论分布假设都能接受；但到α≈0.35（木星）和α≈0．175（金星）；则拒绝第1种假设，而应接受第2－5种假设，尤以第5种理论分布假设为佳.Pj和Pv中难于避免许多重要干扰但仍可检测出.所以，行星潮汐影响太阳因素；故其中，可检测的行星潮汐成分只能较小；活动，仍是种显著的效应．更多还原

【Abstract】 The observed distributions Pj(L) and Pv(L) in heliographic longitude of 1119 solar flares (Im≥2-) occurring in a 6.5yr segment of solar cycle 19, as seen from the orbital positions of Jupiter and Venus, have been investigated in relation to 5 theoreticaI hypotheses (THs). By comparing these THs with observed distributions, the X2 tests show that at strict confidences cr < 0.01, all the THs 1-5 can be accepted, but at a ≈ 0.35 (for Pj) & 0.175 (for Pv), TH 1, "uniform random", must be rejected and THs 2-5, being related to tidal forces, can still be accepted; and TH 5, "uniform random + horizontal and vertical tidal force", is the best of them. It is difficult to refrain from some strong disturbing factors in Pj and Pv alld then the testable tidal compositions in them have to be rather small but can be detected. So the influnces of planetary tide on solar activity are significant effects.更多还原
