A: Unused DDF is carried over for use in a future year.

答: 未使用之经费将移入下一年来使用.

DDF donations in any amount are welcome.

地区指定基金的捐赠任何金额都欢迎.

It is also found that using a DDF with a greater dispersion parameter, or using a smaller walk-off effect can broaden the gain spectrum width and increase the maximum value of gain spectrum.

研究同时发现，较大的色散缓变参量及两光束较小的离散均会使增益谱的谱宽加宽，振幅的增长速度加快。
