That matters as countries with civil nuclear programmes are allowed to come perilously close to having a bomb.

I want to do so many things but come close to nothing.

我想要做的好多事，但是他们都距离我好远。

But to my mind it doesn't even come close to compensating for the lack of GC.

不过对我来说，这样还是没办法抵销缺乏 GC 这件事。

In this paper, using time Petri nets as specification models, system functionality and timeliness are first verified. Then a heuristic algorithm is proposed to optimize the system energy, which is driven by subtasks' energy-gradients and can be further simplified in the case that TPNs are composable. The experimental results show that the proposed methods can support the high-level low-power synthesis of real-time systems with results close to the optimum one, but with very low time complexities.

以时间Petri网为模型，验证系统功能性和实时性，在此基础上，提出了一种由子任务的能耗变化率驱动的启发式能耗优化算法，并针对一类特殊形式的网模型———可组合时间Petri网，设计了相应的简化算法·实验说明，上述算法时间复杂度低，且优化效果接近最优值，能够为实时系统低能耗高层综合提供有力支持

It is shown that as the deviation of the interval factors of the design parameters are similar and close to unity, the computational error of the fast methodology are determined by the dispersion between the interval factors; and the error comes up to zero if all the interval factors are equal.

当诸参数的变化区间相对其均值的离差较小时，区间结构矩阵特征值的计算精度主要由各区间因子的差值大小所决定；且当各区间因子的差值为零时，误差亦为零。

I married a man I met through being randomly seated next to him on a flight – which is as close to computer dating as I was likely to get.

我嫁给了一个在飞机上遇到的男人，我当时完全是随机地被安排在他旁边——这是我最接近电脑速配的经历。

With China's entry to WTO and coming close to international consuetude, periodical editors should realize the related legal rules and learn how to protect the legal rights and interests of editorial office, editors and authors.

随着我国加入WTO和与国际惯例接轨，科技期刊编辑应该了解相关的法律规则，并学会保护期刊编辑部的合法权益，以及编辑与作者的合法权益。

Our results indicate that not only the poloidal convection patterns in uppermost mantle have good correlations to surface tectonic motion, but also the toroidal ones reveal important information of their horizontal motion and rotation for the first time. There is a SEE_NWW strong convection zone close to the equator in toroidal convection patterns, which probably correlates with the large_scale shear zone near the equator and is the deep dynamic background of strong earthquake occurrence in this zone. The opposite rotating large_scale convection rolls in the Southern and Northern hemispheres suggest that maybe there is differential rotation between them.

研究结果表明，不但地幔浅部的极型场对流图像显示出了与大地构造运动的相关性并揭示了其深部动力学过程，更重要的是，地幔浅部的环型场对流图像首次为我们认识和理解板块构造的水平与旋转运动提供了重要的信息：环型场速度剖面中在赤道附近存在一条大致南东东—北西西向的强对流条带，可能与环赤道附近大型剪切带的形成相关，进而表明可能是该带强震发生的深部动力学背景；在南北半球存在的旋转方向相反的对流环表明它们整体上可能存在差异旋转。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
