An average flash unit rating of around 60 joules.
平均估计,一般的闪光单元约为60焦耳.
Every year, approximately 2.5 million joules of solar energy reach the earth.
每年 ﹐ 大约有二百五十万焦耳的太阳能达到地球.
And I call that the power of that neutron star, and that, then, for this mass transfer rate, that's about two times ten to the30th joules per second, which is watts.
中子星的能量,在这个转移速率下,它大概是2乘以10的,30次方焦耳每秒,单位是瓦特,大概比太阳能量的。
