查询词典 time space

It is a holistic, non-material realm that lies outside of space and time, but upon which we impose the categories of space and time and localisation via the mysterious Kantian categories of our minds.

它是一个神圣的、非物质的领域，位于空间和时间之外。在它之上，通过我们的意识这种神秘的康德式范畴，我们赋予了空间、时间和定域性的概念。

The space-time theory of the Relativity--- The fallacy from the experiment perjuries §1 The examination and verification principle of "Space-time twisting" experiment of the Relativity.

相对论时空理论是实验伪例下的谬误一：审思相对论&时空扭曲实验&的验证原理在一些讨论网站，我曾发表以下四点意见恭请大家审思： a。

So in this paper we discuss the content of version management from data storage, and put forward two models of difference storage. Constructing storage threshold unites difference storage and full storage in order to balance space efficiency and time efficiency. It not only improves the answer time of version access but also reduces storage space.

因此本文从数据存储的角度讨论了版本管理的内容，提出两种差值存储模型，构造了版本存储阈值来将差值存储与完整存储相结合，从而有效地在空间效率和时间效率上进行平衡，不仅提高了版本存取的响应时间又减少存储空间。

According to general relativity, time is stitched together with space to form four-dimensional space-time.

根据广义相对论，时间与空间一起形成了四维时空。

The gravitational thermodynamics of space-time foam is studied in Chapter 5 by one-loop quantum gravity and statistical thermodynamics. It is shown by further discussions of Hawking's results that Hawking-Unruh themal radiation should contain thermal gravitons or the contribution of quantum space-time foam. As a by-product, the one-loop quantum gravity correction to the classical black hole thermodynamics is also given.

我们在第五章用单圈量子引力和统计热力学探讨了时空泡沫的引力热力学，对Hawking的研究成果的进一步讨论表明，Hawking-Unruh热辐射应该还包含热引力子或量子时空泡沫的贡献，我们同时给出了单圈量子引力对经典黑洞热力学的校正。

Since every computation that can be done in logarithmic space can also be done in polynomial time it follows that if there is a logarithmic-space many-one reduction then there is also a polynomial - time many-one reduction.

若我们提供一个副函式可以在多项式时间解出&Y&，'''又'''可写出呼叫此副函式的程式并在多项式时间解出问题&X&，代表我们可以将&X&多项式时间图灵变换成&Y&。

The above problems are studied in this thesis. First, the implicit NND scheme with mix flux splitting method proposed by Zhang Hanxin that is first order accurate in time and second order in space is modified. The modified scheme keeps the characteristics of fast convergence and is second order accurate both in time and space. It can be capable of simulating the unsteacly flow. Second, the topological method founded by Zhang Hanxin is improved to study the characteristics of vortex near the singular point on its axis and the cross streamlines on the longitudinal section passing the vortex axis. On the basis of topological results, a program which visualises numerical results is made out. It can help us analyse the characteristics of vortex motion.

本文对上述问题做了研究：第一，在数值模拟方面，借助于张涵信提出的NND算法和混合通量法，我们将他建立的时间为一阶、空间为二阶精度的快速隐式算法推广为时间和空间均为二阶精度的算法，这样做保留了原格式收敛快的特点，而且能适用于真实的非定常流态的计算；第二，将张涵信的拓扑分析方法加以推广，研究了涡轴附近及破裂点邻域内流场的空间特征，并以这些拓扑分析结果为指导，研制了一套显示计算结果的软件，这一软件能很好地帮助我们分析流场的计算结果和旋涡演变的特征。

In the paper, Krein space is introduced, and the H_∞white noise estimation for linear systems (including both discrete-time case and continuous-time case) is considered with the help of re-organization of innovation analysis and projection formulation in Krein space, thus the estimators (mainly filters and fixed-lag smoothers) and the associated sufficient and essential conditions are given.

揭示出H_∞白噪声滤波问题实际上等价于Krein空间内的H_2白噪声滤波问题，而H_∞白噪声固定时滞平滑问题实际上等价于Krein空间内含即时观测和单时滞观测的系统的H_2白噪声估计问题。

本文先介绍两种编码技术的编解码原理，其中空时编码采用差分空时分组码，Turbo编码采用两个递归系统卷积码编码器的并行级联，译码采用SOVA算法。

Therefore, the human world-creating movement is creating a brand-new human space-time, from a philosophical space-time to a Daoist one. This is the deep-level significance of human world-creation.

因此，人类的创世运动是在创造一个崭新的人类时空，由哲学时空创造成为道学时空，这才是人类创世的深层意义。
