可估计的载波频差范围是大的，约为符号率的，并且算法所需的计算负载非常低，适合数字硬件实现。

Its estimation range is large, about of the symbol rate, while the algorithm proposed requires a very low computational load and is very easy to implement with digital hardware.

如果这些输入的频率的分布是可计算、测量、甚至可估计的，则频率响应可以用来决定系统输出的效果。

If the frequency distribution of these inputs can be calculated, measured, or even estimated, the frequency response can be used to determine their effects upon the system output.

据估计，与水有关的可预防疾病每天导致1万至2万名儿童死亡，而最新证据表明，我们在解决这些问题方面仍处于落后状态。

Preventable water-related diseases kill an estimated 10,000 to 20,000 children every day, and the latest evidence suggests that we are falling behind in efforts to solve these problems.

Diet, as we said before, is having a big impact, so estimates are that you can attribute two point six million deaths per year globally to low intake of fruits and vegetables.

如我们之前所说,饮食对健康至关重要,所以大致估计每年全球,有260万人的死亡可归结于,水果与蔬菜的摄入过少
