- 中国大学MOOC: 设某线性电路的单位冲激响应为https://edu-image.nosdn.127.net/42740C7A893EA027EAD1C3A530168119.png?imageView&thumbnail=890x0&quality=100,https://edu-image.nosdn.127.net/CADBA465555ED9687047E00106605E87.png?imageView&thumbnail=890x0&quality=100为输入,则https://edu-image.nosdn.127.net/7DBA57BE4DE0D6ECEEDFBE27B38EBAA7.png?imageView&thumbnail=890x0&quality=100是系统的( )响应。
- 中国大学MOOC: 若https://edu-image.nosdn.127.net/9CEFF7F442424677074D65F375ACE8EC.png?imageView&thumbnail=890x0&quality=100和B为wff,且https://edu-image.nosdn.127.net/86E0063DBB73B64597F5888DD4CF8452.png?imageView&thumbnail=890x0&quality=100则( )。
- 中国大学MOOC: 图示结构中各杆EA相同,则图中C点的水平位移相等。http://edu-image.nosdn.127.net/3620572526D2610D479457257B019DC1.JPG?imageView&thumbnail=890x0&quality=100
