Solar physics 太阳物理学 Sun down 落山的太阳 Several lines of evidence suggest that the sun isabout to go quiet 证据的一些方式表明太阳即将变平静 spots of bother? 太阳黑子的困扰? DURING the four centuries that it has been studied in detail, the sun has usually behaved in aregular manner. 太阳已被详细研究了四百年，它通常以规则的方式反应。 The number of spots on its surface has waxed and waned in cycles that last, on average, 11years. 太阳表面的黑子数在其一般延续11年的活动周期内增增减减。 Such cycles begin with spots appearing in mid-solar latitudes and end with them near theequator. 这样的周期活动以太阳黑子在其中纬度出现开始并随着黑子移动到赤道附近而终结。 And the more spots there are, the more solar storms there are around. 而且太阳黑子的数目越多，周围就会有越多的太阳风暴。 Sometimes, though, the sun sulks and this solar cycle stops. 然而，太阳有时也会生气，之后这种太阳活动周期就停止了。 |
