The egg yolk color is improved by replacing NC with QPM equally ( P < 0.1), but Haugh unit score and eggshell strength are not improved ( P> 0.1).

与普通玉米相比，在日粮中使用优质蛋白玉米可提高鸡蛋的蛋黄颜色评分（P0.1）。

There following innovation points: Firtly, we start our analysis from the concept of phase match width and calculated the bandwidth of the QPM-OPG broadband source according as it.

综上所述，存在以下创新之处：从匹配宽度这一概念出发进行分析，以此作为判定QPM-OPG宽带光源带宽的依据，进行理论研究。

If we introduce the aperiodic or periodic reversal of the nonlinear optical coefficient into the waveguides, the CSHG conversion efficiency can be improved greatly, the configuration also has been called quasi-phase matched CSHG ( QPM-CSHG).

如果引入二阶非线性系数的周期极化反转，即考虑到准相位匹配的情况，切伦科夫倍频效率将会得到极大的提高，可以将之称为准相位切伦科夫倍频（QPM-CSHG）。
