四维的

In this design, the dimension M of the memory vector field may be not necessarily equal to the dimension N of the network vector field. This may be the usually case in applications. Designing a network with either static or oscillating behavior, after analysing the dynamical. behavior of its four-dimension subspace, we get 2-torus in the subspace. If we vary the ratio of the imagine parts of the complex conjugate eigenvalues, the periodic motion of all kinds of period ratio on 2-torus are obtained.

设计一个既具有静态平衡点又具有动态振荡的网络，其静态平衡点由多余维叉形分叉得到，动态振荡形式由多余维Hopf分叉得到，通过对其中一个具有振荡行为的四维子空间的进一步分析，可以得到网络在四维子空间中的二环面运动，适当调整约当形中共轭复特征根虚部的比值，可以得到各种周期比的二环面上的周期运动。

In this article,we mentioned away to found an online-bank risk monitoring system---""four-dimensionality form aorganic whole""monitoring system.The so-called""four-dimensionality form aorganic whole""is to points concrete measures should be applied on nation,industry,bank and customer these four different dimensionality and auniform technique backup--digital authentication center should be set up against the online-bank's risk.

YU Qing-hong, TANG Feng-zhen,BO Yan-hong, et al.Function Department of Hanzhong 3201 Hospital, Shanxi 723000,China Objective To discuss the clinical value of 4D （real-time 3D） ultrasound for diagnose of fetal anomaly. Methods Philips HD11 ultrasonograph was used to observe fetal face, spine and limb structure firstly 2D and then 4D for stereopicture.

目的 探讨四维超声表面成像技术观察诊断胎儿畸形的临床价值方法应用飞利浦公司HD11型超声诊断仪先常规二维超声检查，然后采用四维超声检查显示胎儿各部位立体图像，重点观察胎儿颜面部、脊柱及肢体结构。

A series of copper halides in one, two, or three dimensions have been successfully synthesized such as rhomboid dimers of stoichiometry [Cu2X2L2]n, the tetranuclear species on cubane or stepped cubane tetramers of stoichiometry [Cu4X4L4]n and hexagonal[Cu6X6] grid chains.2 The main strategy in crystal engineering is a secondary building block approach.3 For a given building block, there are two routes to construct frameworks.

在一维、二维或三维的一系列卤化铜已经成功地得到了合成，比如化学计量法[Cu2X2L2]n的长菱形二聚物、化学计量法[Cu4X4L4]n和六边形[Cu6X6]网格链的在立方烷上的四核类或阶梯式立方烷四聚物。[2] 在晶体工程上的主要策略是一种次级构件途径。[3] 对于一给定的构件来说，有两条构件骨架的路线。

It simply means that you are very solidly ensconced in the Fourth, and, thereby, experiencing all four dimensions Fourth-dimensionally.

它仅仅意指：你非常坚定地安住在第四维上，并且，在第四维体验所有的维度。

In order to increase the compression ratio of color video,a new coding method context-based four-dimensional matrix variable length coding was proposed according to four-dimensional matrix theory.

为了进一步提高彩色视频的压缩比，根据四维矩阵理论，提出了基于上下文的四维矩阵变长编码方法。

Now we are domestic so-called four-dimensional color Doppler ultrasound is not actually a real four-dimensional color Doppler ultrasound.

现在我们国内所谓的四维彩超实际上都不是真正的四维彩超。

But you can conceptualize a four-dimensional data structure by thinking of the fourth dimension as multiple three-dimensional cubes.

但是您可以采用将一个四维数据结构看作是多个三维立方体的方式来理解四维数据结构。

S first hot springs, hunting by Charles IV discovered The Charles IV Spring, has stopped the flow of the House of Lords castle Hot Springs, in the spring next to the Charles IV, the goddess of hot springs, hot springs, etc. Hard Rock are in there, it can be said of all the famous hot springs remains卡罗维瓦里almost all gathered here by then.

卡罗维瓦里的第一处温泉、由查理士四世狩猎时发现的The Charles IV Spring、已经停止流动的上议院城堡温泉、在查理士四世温泉旁的女神温泉、硬石温泉等等都在该处，可以说卡罗维瓦里所有有名的温泉遗迹几乎都聚集在此了。

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