     One day, Bob took two of his friends into the mountains. They put up their tents (帐篷) and then rode

off to a forest to see the trees growing.

     In the afternoon, when they were about ten kilometers from their camp (营地), it started to snow. More

and more snow fell. Soon Bob could hardly see his hands before his face. He could not find the road. Bob

knew there were two roads. One road went to the camp, and the other went to his house.But all was white

snow. Everything was the same. How could he take his friends back to the camp?

     Bob had an idea. The horses! Let the horses take them back! But what would happen if the horses took

the road to his house? That would be a trip of thirty-five kilometers in such cold weather!

     It was getting late. They rode on and on. At last the horses stopped. Where were they? None of them

could tell. Bob looked around. What was that under the tree? It was one of their tents!

如图所示电路用的是等效替代法测量未知电阻．

其中R_x是待测电阻（阻值大约几百欧），R是滑动变阻器，R₀是电阻箱（电阻箱的最大电阻值大于R_x）．

请根据实验电路图把下列主要实验步骤中的空白填齐．

①按电路图连好电路，并将电阻箱R₀的阻值调至最大．

②闭合开关S₁

③闭合开关______，调节滑片P，使电流表指针指在适当的位置，记下此时电流表的示数I．

④先断开开关______，再闭合开关______，保持______的电阻不变，调节______，使电流表的示数仍为I．

甲基层法院以抢劫罪判处张某有期徒刑12年，张某不服在法定期间提起了上诉，二审法院在审理过程中，认为一审法院认定事实不清、证据不足，裁定发回重审。请问：如果一审法院重审后仍然证据不足，二审法院应如何处理：

A．二审法院可以再裁定发回重审，一审法院两次重审后仍证据不足，二审法院在查清事实后改判

B．一审法院重审后，张某又提起上诉的，二审法院不能再裁定发回重审，只能在查清事实后改判
