亲,找到规律了吗 第③行数
48=24*2第①行数
亲,找到规律了吗 元芳,你说呢?

这不是很简单的一个问题吗？0+3=33+5=88+7=1515+9=2424+11=35。。。应该看出规律来了吧，求第N项的公式我就不写了，你自己算吧，我没空
0=1的平方-1第二项
3=2的平方-1第三项
8=3的平方-1第四项
15=4的平方-1``````第N项=N的平方-1

急求有经验的朋友给指点一下0.5分以上的植物学方面的SCI期刊，重金感谢！
本来投往African journal of biotechnology的一篇稿子，修改意见都回来了，结果木虫上有朋友说该刊已经被kick出SCI索引了。悲哀啊，我还指着这个毕业啊！
急求有经验的朋友给指点一下，0.5-1分的植物学方面的SCI期刊。我的这篇文章是植物结构和遗传稳定性方面的，技术较普通，但个人做的很仔细。
希望朋友们不吝指点，谢谢围观！

看看。另外African journal of biotechnology杂志今年被踢出，说不定等你文章发表的时候，又被收录了。发吧 植物学SCI杂志大全
