某同学测量一个圆柱体的电阻率，需要测量圆柱体的尺寸和电阻．
①分别使用游标卡尺和螺旋测微器测量圆柱体的长度和直径，某次测量的示数如图 （a）和如图 （b）所示，长度为{#blank#}1{#/blank#} cm，直径为{#blank#}2{#/blank#} mm．
②按如图 （c）连接电路后，实验操作如下：
（a）将滑动变阻器R1的阻值置于最{#blank#}3{#/blank#}处（填“大”或“小”）；将S2拨向接点1，闭合S1，调节R1，使电流表示数为I0；
（b）将电阻箱R2的阻值调至最{#blank#}4{#/blank#}（填“大”或“小”），S2拨向接点2；保持R1不变，调节R2，使电流表示数仍为I0，此时R2阻值为1280Ω；
③由此可知，圆柱体的电阻为{#blank#}5{#/blank#}Ω．
cC(g)＋dD(g)，反应达到平衡后，将气体体积压缩到原来的一半，当再次达到平衡时，D的浓度为原平衡的1.8倍，下列叙述正确的是（ ）
