四维的

Are highly dependent on applications satellites. With the development of times and technology, the strategic instruments of the US global hegemonism transform are changing from export control, trade embargo, finance sanction, full-scale sanction, no-fly zone for aircrafts to NSLZ, and even the military strike from the outer space. By using them concertedly, the US can prevent and control the effective flow of material, personnel, currency, labor and information in or out of other nation in the four dimensions of land, sea, sky and electromagnetism.

随着时代和技术发展，美国全球霸权主义战略工具逐渐从出口管制、贸易禁运、金融制裁、全面制裁、飞机禁飞区、发展到"卫星禁发区"直至自外空进行军事打击，多种手段相配合就能够有效阻止和控制别国陆、海、空、天、电磁四维空间中的物资、人员、货币、劳务、信息的国际、国内有效流动。

On Privalov's first workday, Janus burdened Aldan with the task of four-dimensional convolution in the conjuration space.

On Privalov的第一个工作日， Janus负担了Aldan四维卷积任务在含蓄空间的。

Using the continuity method, we will obtain a theorem of existence of solutions to the equation on 4-dimensional compact Riemannian Manifolds.Finally, we will consider a kind of Kazdan-Warner type equation on compact complex manifolds.

作为上述工作的补充，我们讨论了规范固定Yang-Mills方程，并用连续性方法得到了一个在四维紧致黎曼流形上解的存在性定理。

An example of four dimensional signal space is utilized to compare the computing complexity of the known data and ours.

随后具体实现了一个四维信号空间的例子，比较了和已有数据之间的计算复杂性。

Thinking further, and perhaps realizing this not to be a four dimensional existence, Stephen Hawking, as well as a number of other scientists and thinkers, have found an exception to the Conjecture.

随着进一步思考，人们认识到这不止只有四维空间，史蒂芬·霍金和许多其他的科学家和思想家一样，都发现了这个推测的例外。

In this paper, we investigate some interesting models of dark energy, especially the brane scenario, in which our four dimensional universe is embedded in a higher dimensional spacetime where the gravitation can propagate in.

在胚世界宇宙学框架下，我们所生存的四维宇宙被认为是镶嵌在更高维的时空中，而引力相互作用可以在整个高维时空中传播。

From the angel of four dimensions vector and physics observation, this paper discusses the coordinate transform relationship between the relative movement inertia reference frames.

文章从四维矢量、物理观测的角度出发，就相互运动惯性系之间的坐标变换关系进行讨论。

Theother cross section is a pair of hyperbolic cylinder consisting of two four-dimensionalMinkowskian spacetimes, therefore can explain the doubling of degrees of freedomin the real time formalisms.

另一个截面是由两个四维明氏时空构成的一对超双曲柱面，因而可以解释实时方法的倍自由度。

A novel four-dimensiond hyperchaos system with only one nonlinear term is reported. The Lyapunov exponents spectrum, periodic orbit, quasi- periodic orbit, and the chaos and hyperchaos attractor of this system are obtained.

构造了只包含一个非线性项的四维超混沌系统，得到了系统的Lyapunov指数谱、周期轨道、拟周期轨道、混沌和超混沌吸引子。

Popovich spoke about Bryant's fourth-quarter performance in Houston in reverential tones.

波波维奇带着崇敬的语气谈到了科比在比赛第四节的表现。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
