1·The distinction between covariance and contravariance is important for computations with tensors, which often have mixed variance.
协变和逆变的区别对于张量的计算尤为重要，这往往会出现混合方差。
2·For all of the above discussion to be practical, the team must find a way to compute the variance of the project parameters.
要想将上面所讨论的所有内容都成为可实行的，团队必须找到一个计算项目参数方差的方法。
3·In particular, the team can estimate the three values — lowest, nominal, and highest estimations — assuming that the risk was removed, and then apply these values to reestimate the project variance.
特别地，团队可以估计三个值——最低、标准和最高估计值——交涉去掉了风险，并且应用这些值重新估计项目方差。
4·For example, a metric that does not correlate to the project cost or duration cannot aid in assessing the variance reduction in the iterations.
例如，与项目成本或持续时间无关的度量标准不能帮助评估迭代中的方差削减。
5·They conflated high food prices with greater food price volatility, which is best defined as variance around the food price level.
他们把高居不下的食品价格和幅度较大的食品价格波动(最好定义为食品价格水平的方差)混为一谈。
1·I mentioned the potential variance caused by the choice of prefixes.
我提到了前缀选择造成的各种可能的变化。
2·This reduction in uncertainty also reduces the variance in estimations, since there is a direct correlation between these factors and the ability to produce sound estimates.
这种不确定性的削减还减少了估计中的变化，因为在这些因素和生成可靠估值的能力之间存在直接的关联。
3·The new individual will, in theory, be as fit as the parents, plus or minus a small variance caused by the mutation.
理论上说来，新的个体是和双亲一样适应的，由于变异或增或减会有些微小的变化。
4·We approximate the free memory after a garbage collection cycle by using algorithms that analyze the variance of free memory statistics.
通过使用分析可用内存统计信息变化的算法，我们可粗略计算垃圾收集周期之后的可用内存。
5·At the same time, because white noise does not have any recognizable variance, most people eventually don't notice they are hearing anything at all.
同时，因为白噪音没有任何可识别的变化，大部分人最终没有注意到他们所听到的任何东西。
