  1. The Sun is not considered a variable star , but it does undergo periodic changes in activity known as the sunspot cycle .

    太阳是不被认为是变星,但它的变化进行定期的活动被称为太阳黑子周期。

  2. Further analyses show the variation of earth rotation rate and sunspot cycle length have important role on the climate abrupt change in the Qinghai-Xizang Plateau .

    进一步分析表明,地球自转速度和太阳黑子周期长度的变化对高原及北半球本世纪气候的突变和阶段性变化起着重要的作用。

  5. The surface heating fields over QXP die down when sunspot cycle length ( SCL ) become long ( the sun activity die down ) .

    太阳黑子周期长度(SCL)变长(太阳活动减弱)时,青藏高原地面加热场强度减弱。

  6. When the belt is turning " fast ," it means that lots of magnetic fields are being swept up , and that a future sunspot cycle is going to be intense .

    当带正在转向“快”,这意味着大量的磁场正在扫地,而且未来的太阳黑子周期将是激烈的。

  7. The lag ratio of cosmos earth system field ( 18 % ~ 27 % ) calculated through sunspot cycle is one of the parameters which can be used to calculate the time and period of the SL and MF type lag .

    应用太阳黑子活动周期计算的宇地系统场的滞后率(18%~27%)可以作为推算SL型和MF型滞后时间量和周期的参数。

  8. We Summarize the theoretical studies of long-term solar activity on sunspot cycle , extended cycle , the prediction of solar activity and the asymmetric distribution of solar activity on the hemisphere and present the results of our studies on the long-term solar activity .

    本文综述了太阳活动周期、太阳活动延伸周、太阳活动预报和太阳活动在日面上分布等有关太阳长期活动规律的理论研究;

  9. A quasi - periodic wave length about 2.1-2.8 ka was found with Δ 14C recorder since 15 ka BP and with the sunspot cycle length ( SCL ) over past 2600 years . They are identical in climate wave of cold and warm over the global .

    利用1.5万年来的Δ14C记录和2600年来的太阳黑子周期长度(SCL)资料,发现太阳活动存在时间尺度为2.1~2.8ka的准周期波动,它们与全球气候的冷暖波动非常吻合。
