- 用if判断语句判断[img=95x21]18032b97de3c59a.png[/img],在MATLAB中if后的判断应写为 A: 60<x<=80 B: x<=80~x>60 C: x<=80|x>60 D: x<=80&x>60
- 如图所示，真空中，矩形导体框架置于通有电流I的长直载流导线旁，且两者共面，AD边与直导线平行，DC段可沿框架平动，设导体框架的总电阻R始终不变。现DC段以速度v沿框架向下作匀速运动，则当DC运动到图示位置（与AB相距x）时，穿过ABCD回路的磁通量[img=22x23]18035e9bf631ab5.png[/img]为（ ）[img=228x311]18035e9c01eb7a0.png[/img] A: [img=95x44]18035e9c0fadb87.png[/img] B: [img=95x44]18035e9c1d5c33c.png[/img] C: [img=36x44]18035e9c2578181.png[/img] D: [img=93x44]18035e9c2e59f6e.png[/img]
