在GSM规范中要求的，同频C/I防卫比不小于（），邻频C/I防卫比不小于（）.

（1）声控开关在接收到一定响度的声音时，会自动闭合一段时间．某地下通道两端入口处各安装一个声控开关来控制通道中间的同一盏螺纹灯泡．为确保行人无论从通道那端进入，都只能使进入端的声控开关闭合，让灯泡接通电源而发光．请用笔划线代替导线，按上述要求及安全用电原则将图甲中的元件正确地连接到电路中．

（2）在测量标有“0.3A”字样小灯泡的额定功率的实验中，估计灯泡额定功率约为1.5W，电源电压保持不变，使用的电流表“0﹣0.6A”、“0﹣3A”量程完好，电压表“0﹣3V”量程完好，但“0﹣15V”的量程已损坏，滑动变阻器的铭牌上标有“50Ω、1A”字样．同学们按图乙正确连接好电路，滑动变阻器的滑片P在最大电阻位置上，闭合开关时，电压表、电流表的示数分别为2V和0.2A，则电源电压为　 V；

由于电压表0﹣15V量程损坏，从电路中撤去了电压表，然后缓慢移动滑动变阻器滑片P，当电流表示数

为　 　A时，灯泡正常发光；观察发现此时滑动变阻器滑片P恰好处于变阻器的中点位置，据此计算出灯泡额定功率为　 　W．

除数是589，商是56，余数是586，被除数是______．

下列关于支票使用范围的表述中，正确的是（）。

A.单位和个人的各种款项的结算

B.单位和个人在异地的各种款项结算

C.单位和个人的各种现金的结算

D.在同一票据交换区域的各种款项结算
