In fresco painting, time may be a combination of the past, the present and the future. It may also be an expression of a continuum of time.

在壁画里，时间可以是过去、现在、未来的组合，也可以是一个事件发生的时间延续过程。

This is that one is chill winter,But be a brief season all the time,Frigidity will be over all the time , resembling our one fine day right away may die.

这是一个寒冷的冬天，但始终是个短暂的季节，寒冷始终会过去，就像我们总有一天会死去。

The frontogenesis process involves in the interactions among the systems of multiple scales. Since the hardness of the nonlinear problem, it is difficult to study frontogenesis analytically. The introduction of the effects of orography, friction and diabatic processes generally makes impossible the analytical resolution of the problem and leads to the use of numerical models. Primitive equations are numerical integrated together with a detailed description of physical processes. The circulation obtained is then used to diagnose and test theoretical mechanisms. It should be noted, however, that a fully description of frontogenesis in explicitly resolving the of large-, meso- and micro-scale flow in the same framework is not yet possible because of the excessive computer capacity and the time required. In order to deal with the problem, the action of large-scale background has been simplified and taken into consideration through the addition of the forcing into the nonhydrostatic cloud model.

大气锋生是一种多尺度相互作用的过程，理论研究遇到非线性的困难，在考虑地形、摩擦、非绝热等物理过程之后，解析研究更加棘手，通过数值模拟搞清其中的物理机制是重要的研究手段，但是把大、中、小尺度甚至微尺度的系统及其相互作用过程在一个模式里同时模拟好仍然受计算机速度和容量的限制，本论文在非静力云模式中通过强迫方式加入大尺度变形场的作用，在考虑到大尺度背景作用的同时，可以充分利用云模式所提供的丰富物理过程、非静力和高分辨率特点，开展一些过去较难进行的研究工作。

When it was checked this year and confirmed to be correct, mathematicians around the globe breathed a sigh of relief. Mathematicians' work in this area in the last three decades was predicated on the principle that the fundamental lemma was indeed accurate and would one day be proved.

这让全世界的数学家终于松了一口气，因为在过去30年中，数学家在这一领域的工作都是在"基本引理"是正确的并且终将有一天得到证实的基础上进行的。

Instead genotype of unbalance gametophyte iscomposed of diversified genes from distantly relatedparents and the gametogenesis would abort because ofcontradiction in the haploid cells.

本试验结果结合过去的研究，说明水稻亚种的分化是自然选择作用于遗传变异的结果，生殖隔离是籼亚种和粳亚种连续积累的遗传分岐的产物。

In the past used the live geese, wood is now used to do the wild.

过去用的是活的雁，现在使用的是木头做的雁。

Since the seminal work of Coase,however ,it has been recognized that in practice,although facilities may be provided by local or central government,these goods and services seldom exhibit the strict economic features of a public good;they are lagerly neither non-rival （for example,public parks get congested and fire-services can easily be over-extended）,nor are they non-excludable （whilst it is easy to stop people getting into a public park, fire services in the past were regularly only provided to those who paid the companies fees）.

不过，自从科斯的巨大影响著作面世后，已被公认的是，虽然设施是由地方或中央政府所提供，但在实践中，这些物品与服务很少显示一个公共物品严格的经济特点；它们多数不是非竞争性的（比如，公园的拥挤和消防服务的过度扩展），也不是非排他性的（阻止公众进入公园不难，同时，过去的消防服务时常只为缴费者提供服务）。

It would be easy to persume that the past 100 years were the golden age of discovery.

它会是容易对persume，过去100 年是发现的黄金时代。

Unbelievable is Lee Hom's new album. Perhaps what's hard to believe is that in the past two years, this good-looker has hit emotional highs with music breakthroughs, but also plunged into the depths of loneliness.

不可思议》是力宏新专辑的名称，但也许更不可思议的是在过去两年，这位俊朗的帅哥因为音乐上的突破而登峰造极，在另一方面，却也跌入深深的孤寂。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
