You can also use indices less than zero, which then count backward from the end of the list. So the final statement of the previous example could also be written like so.
您还可以使用小于0的索引，这些索引从列表的末尾往前算。
In the present implementation at least, if this sum is less than zero, the net sets the node to -1, and if it is greater than or equal to zero, the net sets the node to + 1.
至少在当前的实现中，如果这个和小于0，网络就将节点设置为-1，如果它大于或等于0，则网络将节点的值设置为+ 1。
The results show that the effective exchange integral values are less than zero under different conformations, so the radicals display the anti-ferromagnetic coupling.
结果表明，不同构象下各体系有效交换积分值都小于零，自由基间表现为反铁磁性耦合。
