CFMS怎么记

The effectiveness of CFMS to the EMI ( Electromagnetic Interference) suppression of switching converters was then investigated. Moreover, the principle of the suppression of EMI noise by CFMS was analyzed and a simulation model for component-level circuits was constructed.

文中探讨了混沌频率调制技术在开关变换器中抑制电磁干扰的效果，分析了混沌频率调制抑制EMI噪声的原理，并建立了元件级电路仿真模型。

Simulated results show that, by means of CFMS, the peak value of the swit-ching-harmonics effectively decreases and the output voltage is slightly influenced, indicating that CFMS is applicable to switching converters.

仿真结果表明该技术能有效降低开关谐波峰值，而且对输出电压影响不大，具有应用前景。

At present, reform of county forestry management system ( CFMS) has achieved great effect. But, it also has many problems and still is a key factor of development of county forestry.

目前县级林业管理体制改革已取得了重大成效，但也存在着不少问题，仍是县域林业发展的一个关口。
