Durum is the hardest of all wheat and typically contains higher average protein content (12％～ 14％)than wheat of other classes. With a general shortage of protein in the world, breeders focus on improving the total amount of protein in wheat.

多伦小麦是小麦中最坚硬的，含有典型的与其它品种的小麦相比较高的平均蛋白质含量(12％～14％)，由于在世界上的通常缺少蛋白质，因此种植者把重点放在改善提高小麦中的蛋白质总含量。

For the ill conditioned load flow caused by the error produced in the transformation from electricity quantities to average power, direct current load flow and sensitivity vector are presented to find out the ill node, then by adjusting the load curve and generation curve in a certain principle, which is shown in detail with several flow charts, a new operation mode is reestablished to ensure the convergence of the calculation. Optimal multiplier method is proposed to work out the least square solution according to ill conditioned structural power network. The electricity quantities flow method enhances the reliability and accuracy of the calculation of the power transmission losses.

该方法可根据当前输电网中各个变电站24小时的电量记录，利用电量潮流计算对输电网总线损和各条线路损耗进行计算，使计算的精度满足降损措施分析和指标考核的要求；并且对于由负荷出力曲线转化成平均功率计算潮流时引入的误差，进而导致潮流计算不收敛的情况，采用直流潮流法，依据相角对有功功率的灵敏度向量判断出"网络异常点"，并且给出了解决此种情况的方法流程图；针对结构病态的电力系统潮流计算不收敛的情况，运用非线性约束优化方法中的最优乘子法求解潮流方程的最小二乘解，从而解决了电量潮流法计算理论线损时的收敛性问题，增强了该方法的适用性。

Are there ways to measure instantaneous speed directly, or is instantaneous speed always a value that must be derived from average speed measurements?

有没有方法可以直接测量瞬时速度，或者是否瞬时速度总要由平均速度的测量值求导得出？

Because of the uncertainty of risk, the measure on risk must be based on some reliability. The interval estimation of average total claims is also discussed in a simple situation.

由于风险的不确定性，这种风险的度量必是基于某一可靠性的，因此在一种简单情况下讨论了平均总理赔的区间估计问题。

By 1997, the average lifespan increased to over 76 years, with 23.3% of total deaths caused by cancer.

到1997年，平均寿命增加到76岁， 23.3 ％的总死亡所造成的癌症。

Part 1: Fifty-four healthy cross-bred(Luxi×Limousin) beef cattle were selected to study the energy and protein metabolism rules and requirement at the age of 4~6 month. The results showed that the digestibility of DM , OM and energy were 59.68±5.46%, 64.10±7.82% and 66.60% respectively;the metabolizability of gross energy and digestible energy were 56.95% and 85.51%.

第一部分选用54头健康、体重相近的3月龄利木赞×鲁西黄牛杂交牛研究了4～6月龄阶段的能量和蛋白质需要量及其代谢规律，结果表明：犊牛对日粮的DM消化率为59.68±5.46%，OM消化率为64.10±7.82%；能量的平均消化率为66.60%，总能代谢率和消化能代谢率分别为56.95%和85.51%。

Difference in N uptake responsiveness was linked to their difference in N uptake rate and root characteristics. N uptake rate of high-responding cultivars increased significantly with increasing N rate, while their total root length exhibited a comparatively lower variation.

对氮响应度高的4个水稻品种的平均吸氮速率随着供氮水平的增加其增幅显著，而其总根长的变化幅度则较小。

At first, three requirements of image denoising are proposed, based on which the defect of the fidelity term used in the mean curvature motion model and that in the total variation based image denoising models are investigated.

在讨论了图像去噪的3个基本要求的基础上，总结了平均曲率运动去噪模型和总变差去噪模型中利用保真项的不足。
