1.持续时间,存在时间;期间
2.持久,持续
1.the period of time during which something continues to happen or exist
1.Durations and displacements were fully crossed, so there was no correlation between the spatial and temporal components of the stimuli.
三个实验中，长度和持续时间充分的完全交叉（crossed），这样刺激的时间和空间特性之间就没有任何相关了。
2.For this reason, iteration durations are likely to last at least a few days.
出于这个原因，迭代持续时间最少也要好几天。
3.IPF and Provident loan out smaller sums of money (the equivalent of a few hundred dollars, typically) at shorter durations and higher rates.
远景金融和国际个人金融（IPF）所提供的贷款，往往数额较小（放贷金额通常相当于几百美元），还贷时间较短，利率较高。
4.Unless otherwise noted, a power is instantaneous and has no lasting effect. The two types of durations are conditional and sustained.
除非有特定的说明，能力是即时的，无持续效果。持续的时效有两种，分别是条件性和维持性。
5.The sale of structured products will be a particularly important tool with durations of up to three months seen as the "sweet spot" .
结构化产品的销售将成为特别重要的一项工具，而最长3个月的期限则被视为“甜蜜点”（sweetspot）。
6.Three point estimation : sometimes referred to as PERT analysis, is a great tool for estimating activity durations.
三点估计：有时候也被称为PERT分析。这是一个很好的估计活动需时的工具。
7.Or , if you need to cut costs to meet your budget , you might have to decrease scope by cutting tasks or reducing task durations .
或者，在需要削减成本以满足预算时，您不得不通过减少任务或缩短任务工期来缩小范围。
8.The durations and task relationships are also shown in the Gantt Chart and Network Diagram views of your project.
工期和任务关系还显示在项目的“甘特图”和“网络图”视图中。
9.In a few spheres of finance, such as high-frequency trading, it is possible that ultra-short durations cause more harm than good.
在金融的某些领域，比如高频交易，存在超短期限弊大于利的可能。
10.Project can calculate a realistic schedule for you, often based solely on task durations and task dependencies that you enter.
Project通常只根据输入的任务工期和任务相关性，就能为您计算出实际的日程。
