Conclusion: CFF training is an effective method for raising spacial and horary visual acuity.

结论：闪光临界融合频率训练是提高时间和空间视敏度的有效方法。

The effect CFF with different hole on structure and properties of ZL204A has been studied in this paper.

研究了不同 孔 眼密度的泡沫陶瓷过滤器对ZL204A的组织和性能的综合影响。

The main points of CFF' s cost management is to take effective technical steps to reduce the consumption of electricity and product cost.

因此，采取行之有效的技术措施，降低产品的电耗，从而降低产品的生产成本，是企业成本管理的重要内容。

The results show that with low loading level the metal coated CFF provides excellent EMS property in a wide frequency range due to its cavity structure and metallic coating.

研究表明：利用碳毡的孔洞结构和尺寸，辅之以金属镀层，能在较宽的频率范围内对电磁波有良好的屏蔽效率，且不需要很大的填充量。
