查询词典 time space

Einstein claimed that matter and energy are interchangeable, so that there is no "absolute" time and space. There are no constants at all, and measurements of time and space depend on the position of the observer. They are relative.

Mechanical materialism While acknowledging that space and time are independent of the objective existence of people outside, but it will be the movement of phase separation and material that are not dependent on the motion of matter of" absolute space "and "absolute time."

机械唯物主义尽管承认空间和时间是独立于人之外的客观存在，但却将之与物质的运动相分离，认为有不依赖于物质运动的"绝对空间"和"绝对时间"。

Moreover, Newton's absolute time and space that can explain this phenomenon in a sense, trying to shake the special theory of relativity of time and space.

更有甚者，认为牛顿的绝对时空观在某种意义上可以解释这种现象，试图撼动狭义相对论的时空观。

The "interiorization" of space and time: Time and space are abstract words.

本文以三部份来阐述他独特的建筑理念。

Moreover, he confuses real time and space, limited like the things they develop, with ideal or abstract time and space, which alone are general and without limit.

此外，他还混淆真正的时间和空间，有限的一样，他们开发的东西，理想或抽象的时间和空间，这仅仅是一般，没有限制。

Integrating trellis-coded modulation with threaded algebraic space–time block code, trellis-coded modulation space-time block code is presented, which has the advantage of full-diversity and small detection delay. Based on TCM pre-processing, the minimum distance between different codeword matrixes of the TCMST block code is maximized, so the average bit error rate of the TCMST block code is lower than that of the TAST block code at the same signal noise ratio.

TCMST分组码具有满发送分集度和检测延迟小等优点；由于采用了TCM预处理，使得不同TCMST分组码码字矩阵间的最小距离达到了最大化，因此在相同信噪比情况下，TCMST分组码具有比TAST分组码更低的平均误比特率。

Simulation results show that our algorithm enforces the adaptability of differential space-frequency modulation to the time delay expansion.Finally, we give our work to reduce the complexity of multiple symbol differential sphere decoding in differential space-time modulation. Through the modification of the enumeration strategy of the search tree in sphere decoding, we significantly reduce the complexity of detection at the expense of little loss on performance.

理论分析和仿真结果都验证了这种检测算法对长信道时延的适应能力论文最后还对差分空时调制中的多符号检测算法进行了研究，提出了一种降低差分空时调制系统中多符号差分球形译码算法复杂度的方法，通过改进球形译码中搜索树的排序策略，使得系统在牺牲较少性能的基础上大大降低了算法实现的复杂度。

His unique methodology of conveying the notion of "Consilience" reflects the collapsed firm walls of the relations between human to human, object to object, space to space, time to time, and emotion to emotion.

他以其独特的方式传达统一的观念，表现着像倒塌的墙壁般的人与人，物与物，空间与空间，时间与时间和情感与情感之间的关系。

With performance analysis and numerical simulations, it is shown that the two space-time receivers can greatly resist MAI and alleviate "near-far" effect problem, the BER performance of which is far more better than that of the convectional space-time RAKE receiver and the adaptive implementation of which can quickly converge.

自适应子波神经网络多用户检测器需已知系统中所有或部分用户的信息，整体复杂度较相应的单用户检测器高，但性能有明显改善，采用部分用户参加的多用户检测，容易实现性能与复杂度的对换。

In addition the distinguishing of Time and Space Coupling Club Convergence is to simultaneously test the club convergence of time dimension and space dimension.

而将区域之间的相互联系纳入分组中的探索性空间数据分析方法较适合空间俱乐部趋同的区域组划分。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
