Millions of fridges hum away continuously, and at vast expense, busily maintaining an artificially-cooled space

里忙碌地维持着一个人为的清凉空间，而户外，大自然免费提供着我们希望的温度。

Every winter, millions of fridges hum away continuously and at vast expense, busily maintaining an artificially-cooled space inside an artificially-hearted house-while outside, nature provides the desired temperature free of charge.

每年冬天，上百万台冰箱不断的嗡嗡作响，花费很大，在人工制热的房间里忙碌地维持着一个人工制冷的空间，而在室外，自然免费提供理想的温度。

But if you take rights of others seriously, if you regard that citizens and their claims to their little space make a difference, then I am afraid the longer route becomes inescapable, no matter if it delays the autobahn or if the train to Rome arrives 25 minutes late.

但是，如果你想严肃地对待其他人的权昨，如果你认识到，老百姓和老百姓拥有自己的空间，是不一样的，那么，我想，花费更长的程序，是难免的，无论是它是否延续了高速公路的建设，还是指罗马的火车是否晚点了25分钟。

The experiment results of real SAR scenes show that the presented scheme has the characteristics of strong robustness, extensive practicability, high automatic on low computation and easy realization. Therefore, the presented scheme has the extensive prospect for spatial earth observation.

实测数据的实验结果证明了新方案具有稳健性强、适用性广、自动化程度高、计算量小、工程实现易等特点，说明了该方案对于空间对地观测具有广泛的应用前景。

Typically, online aggregation algorithms on multi-dimensional data need additional auxiliary data for estimation, which make the performance of the storage and maintenance of the data cube worse.

以往在数据立方体上实现的联机聚集往往需要附加空间来存储联机聚集估算所需要的信息，极大地影响了数据立方体的存储和维护性能。

As we all known, with the founding of Euclidean geometry in ancient Greece, with the development of analytic geometry and other kinds of geometries, with F.Kline" s Erlanger program in 1872 and the new developments of geometry in 20th century such as topology and so on, man has developed their understand of geometry. On the other hand, Euclid formed geometry as a deductive system by using axiomatic theory for the first time. The content and method of geometry have dramatically changed, but the geometry curriculum has not changed correspondingly until the first strike from Kline and Perry" s appealing.

纵观几何学发展的历史，可以称得上波澜壮阔：一方面，从古希腊时代的欧氏综合几何，到近代解析几何等多种几何的发展，以及用变换的方法处理几何的埃尔朗根纲领，到20世纪拓扑学、高维空间理论等几何学的新发展，这一切都在不断丰富人们对几何学的认识；另一方面，从欧几里得第一次使用公理化方法把几何学组织成一个逻辑演绎体系，到罗巴切夫斯基非欧几何的发现，以及希尔伯特形式公理体系的建立，极大地发展了公理化思想方法，不管是几何学的内容还是方法都发生了质的飞跃。

Furthermore,it shows that if E is a barrelled space with continuousdual 〓,then 〓 contains no copy of 〓 if and only if each〓 is compact operator.

据此证明了若E是桶型空间，那么〓〓不拓扑同胚地包含〓的充要条件是每个〓都是紧算子。

If every element of date base has effective time and space can better describe impersonal thing, so it may be more value.

如果数据库中的每个元组均有其有效时间和空间，那么在数据库中所发现的知识在其有效时空约束内就是有价值的，这种具有时空约束的规则可以更好地描述客观事物，因而也会更有价值。

The research results provide basis for quantitative appraising natural environment and predicting soil moisture's distribution and spatial variability and availably controlling、preventing and curing soil basification.

研究成果为定量评价水土资源环境，预测农田土壤水分的分布和空间变异规律，有效地控制、防治土壤盐碱化提供了依据。

The competition area must be flat and devoid of hazard.

比赛场地必须有足够的空间，让"形的比赛"间断地进。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
