因此，通过提高PMMA粉的平均粒度及粒度分布宽度，降低堆积空隙率，可以在结构上为提高粉液比提供可行性。
The results indicated that the packing of PMMA beads with lognormal distributions was different due to the difference of mean parti…
实验中获得的由二极管注入泵浦功率至opo信号光平均输出功率的转换效率达4.2%，信号光脉冲宽度比消耗后的泵浦光脉冲宽度压缩了13倍。
The conversion efficiency of the average power is 4.2% from pump diode to OPO signal output and the signal pulse duration is about 13 times shorter than that of the depleted pump light.
