题目:

国家统计局小康研究课题组对城镇居民生活小康标准5个方面12项指标进行监测显示:1999年我国城镇居民生活水平小康实现程度达到94.3%。在12项小康指标中有10项达到或者基本达到小康初始水平。但是还有两项指标,即文化教育娱乐支出比重和人均绿地面积与小康标准有一定差距。从5个方面来看,经济发展、物质生活和人口素质三个方面小康实现程度已经达到100%;精神生活水平和社会保障水平两个方面指标分别只达到86.7%和75.6%。各地区城市小康实现程度也存在较大差距。三大地带相比,1998年实现程度综合得分仍然差异较大,中、西部比东部分别低7.9个百分点和12.97个百分点。但与1996年相比,东部地区小康实现程度由91.87%下降到91.70%;中、西部实现程度分别由79.8%和74.4%提高到83.80%和78.73%。

从上述资料中,不能推出的是:

A.1996至1998年间,中、西部地区小康实现程度的增幅高于东部
B.1996至1998年间,中、西部经济的发展速度快于东部
C.1996至1998年间,东部地区小康实现程度略有下降
D.1996至1998年间,西部地区小康实现程度增幅高于中部

(1)下图为一正在测量电阻中的多用电表表盘和用测量圆柱体直径d的螺旋测微器,如果多用表选用×100挡,则其阻值为         Ω、圆柱体直径为         mm.

(2)如图a所示,是用伏安法测电电动势和内阻的实验电路图,为防止短路,接入一保护电阻R0,其阻值为2Ω.通过改变滑动变阻器,得到几组电表的实验数据,并作出如图b所示的U-I图象:

①根据U-I图象,可知电电动势E=         V,内阻r =          Ω.

②本实验测出的电源的电动势与真实值相比是      .(填“偏大”、“偏小”或“不变”)
