Field plot tests indicates that there are remarkable differences in the loss rates of spike, thousand grain weight and output among different wheat varieties or lines.

田间小区试验表明，不同小麦品种(系)间的穗重损失率、千粒重损失率和产量损失率存在显著差异。

Output can be improved by reducing the plant height, improving available spikelet and seed setting rate and combining kernel number per spike with thousand kernel weight.

适当降低株高、增加有效小穗数、提高结实率、穗粒数与千粒质量并重、主攻穗粒质量是提高小麦产量的有效途径。

Theoretically, the expected output of impulse deconvolution is a spike, whose frequency spectrum can be considered as that of white noise.

从理论上说，脉冲反褶积的希望输出信号是一个尖脉冲，其频谱可以看成是一个白噪信号的频谱。

The output rebound was in line with a spike in January sales figures released earlier in the month.
