標題[問題] 南半球的隕石比北半球少?
時間Thu Apr 10 21:51:03 2008
這是我的英文課本的其中一段話
Today,the governments of serveral countries try to locate
NEAs(near-Earth asteroids). Universit and amateur astronomers
also watch out for dangerous asteroids. However,there are problems.
First,most asteroids are small and dark. That makes then difficult
to spot. Second,if an asteroids is coming from the direction of
the sun,it cannot be seen because the sun is too bright.
Finally,thereis no large-scale program in the southern hemispthere
to try to find asteroids.
中間說的又黑又小所以不好找這還理解
不過後來說的”從太陽來的asteroids命中南半球的機率比北半球小”
這就不太清楚了
是因為南半球的面積比較少這樣而以嗎?
還是還包含地球傾斜的角度、形狀(橢圓形)...等
或者還有其他理由呢?
請內行解答,謝謝!

3F:推 richang:我想他的意思是. 南半球沒有大規模的找NEAs的計畫 04/10 23:16
4F:→ assddd0206:我是想說,南半球的NEAs沒有高機率被找到,加上前面從 04/10 23:26
5F:→ assddd0206:太陽來的,所以我才這樣解讀,主要就是想問說為什麼南 04/10 23:27
6F:→ assddd0206:半球的機率會不高? 04/10 23:28
