- The e xperiment results demonstrate that chaotic frequency modulation (CFM) can improv e the EMC of SMPS, and the EMC of SMPS modulated by the different discrete chaot ic sequences are not obviously different. 实验结果表明混沌频率调制可以改善开关电源的EMC性能,同时可以看出不同的离散混沌序列调制后的开关电源EMC性能相差不大。
- By theoretical deduction, a function relationship between mass flux and vortex frequency as well as the boa rd force of the target flowmeter is established, and its validity is proved by e xperiment data. 经过理论推导得出质量流量与涡街信号的频率、靶板受力的函数关系,并通过实验数据验证了此关系的正确性。
