黑子周期

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。

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 .

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。

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

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。

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

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。

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 .

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。

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 .

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。

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 .

这是一个关于干旱与太阳黑子活动周期有关的令人感到有趣的理论。

This is an intriguing theory that droughts tie in with the sunspot .

北京地区太阳黑子活动周期和年降水关系的初步研究

A Preliminary Study on Relationship Between Cycle of Sunspot and Fluctuation of Precipitation in Beijing Area

本文报导了上海及其邻区Ms≥43/4级地震活动与地球自转速率和太阳黑子活动周期有关。

This paper presents the relation between the seismicity ( Ms ≥ 4 3 / 4 ) of Shanghai with its adjacent areas and the rotation rate of the earth as well as the sun spot cycles . According to such a relation .

北半球海平面气压对太阳黑子11年周期的响应

The response of sea - level pressure to the sunspot cycle for last one hundred years

太阳黑子的出现周期是每11年一次，这个周期性活动同时改变太阳的磁场。

The11-year solar cycle , which governs the appearance of sunspots , also changes the sun 's magnetic field .

黑子的活动周期为11.2年，但也会经历更长期的变化，顶峰和低估可以持续一个世纪左右。

Solar activity varies over an11-year cycle , but it experiences longer-term variations , highs and lows that can last around a century .

太阳黑子活动的周期约11年，太阳系九大行星（包括月球）对太阳引潮力合力的极大值周期也是约11年。

The cycle of the sunspot activity is about 11 years ; the maximum cycle of the resultant of tide-drawing force from the nine planets of the solar system ( including the moon ) upon the sun is also 11 years .

与太阳黑子11年活动周期一致，而且发生在谷年附近。

There existed coordination between geofracture and eleven active cyclic years of sunspot , and occurred in the near valley year .

太阳活动具有极其复杂的周期性，其中太阳黑子的11年周期已是不争的观测事实。

The periodicity of the solar activities is very complex , nevertheless , the 11 years cycle of the sun is beyond the disputations .

此外，这两个相接双星的轨道周期还表现出了周期性的变化成分。和变化的黑子一样，轨道周期的这种变化，也可能是由磁活动引起的。

Moreover , the orbital periods of the two contact binaries show cyclical oscillations , which may arise from magnetic activities just as the dark spots do . 4 .
