查询词典 sunspot

Reliable predictions of sunspot numbers are impossible to make until the solar cycle is well established, usually three years after the minimum.

而通常情况下，在黑子数量最低点出现三年以后，直到太阳活动循环体系已经完善的建立了，人们才可能做出可靠的关于太阳黑子数目的预测。

Monthly averages of the sunspot numbers show that the number of sunspots visible on the sun waxes and wanes with an approximate 11-year cycle, The last five cycles are shown in the diagram below.

平均每月的太阳黑子表明，太阳的黑子数量上可见蜡和循环减弱的一个近似11年的周期，最后5个在图中所示。

The sunspot numbers is the major targets which describes the solar activity level,The solar activity influences human s health and human to rely for existence directly of environment-the Earth.

太阳黑子数是描述太阳活动水平的主要指标，太阳活动直接影响人类健康和人类赖以生存的环境—地球；依据数字信号处理原理，采用多种处理方法，分析处理了1770-1869年的太阳黑子数年均值；得出了太阳黑子存在11-12年周期的结论。

This event was caused by the solar activities such as increases of the sunspot numbers, occurrence of a 3b optical flare at 22 h46 mUT on March 22,1991 and so on.

这次磁暴是由磁暴前太阳黑子相对数增多、3月22日22h46mUT有3b级耀斑爆发等一系列太阳活动所引起的

There are many solar active phenomena, such as sunspot, solar flare, solar prominence and coronal mass ejection.

太阳上有各种各样的活动现象，如黑子、耀斑、日珥和日冕物质抛射。

Magnetic field plays a central role in solar activity. Almost all kinds of solar activities, such as sunspot, solar flare and coronal mass ejection, are associated with solar magnetic fields.

磁场在太阳活动中扮演着主要的角色，太阳表面上各种活动现象（如太阳黑子、耀斑爆发和日冕物质抛射等）都和太阳磁场有关。

Magnetic field plays central role in solar activity. Almost all kinds of solar activities, such as sunspot, solar flare and coronal mass ejection, are associated with solar magnetic field.

磁场在太阳活动中扮演者最主要的角色，太阳表面上各种活动现象(如太阳黑子、耀斑爆发和日冕物质抛射等)都和太阳磁场有关。
