无法用pspice仿真晶体管??

仿真晶体管时显示如下错误:
ERROR -- Less than 2 connections at node N001061
ERROR -- Less than 2 connections at node N001221
ERROR -- Less than 2 connections at node N00969
应该都联上了啊,找不到错误,请大家帮我看看,电路图如下
500) {this.resized=true; this.width=500; this.alt='这是一张缩略图，点击可放大。\n按住CTRL，滚动鼠标滚轮可自由缩放';this.style.cursor='hand'}" onclick="if(!this.resized) {return true;} else {window.open('http://u.dianyuan.com/bbs/u/48/1167228960.gif');}" onmousewheel="return imgzoom(this);">
