查询词典 symmetric

Green : In some ways, it draws off the original intentions for Midship, as a symmetric map built for CTF, with lines of sight that allow a defender to participate in the capture of an enemy flag without abandoning his post. Combat on the upper surface of the map has a flavor similar to Burial Mounds, though—or at least, the more cover rich areas of Burial Mounds.

A：某种意义上来说，设计隔离区的意图跟前作的船舰中央很接近——为夺旗模式设置的对称地形，互相可见的多个点让防守方找人方便而用不着到处转悠；地表高区的战斗更像前作的坟冢，至少很像坟冢的多掩体开阔地带。

Chiral ligands mentioned above and their complexes with acetate copper were used as enantio-selective catalysts in asymmetric cyclopropanation reactions of diazoacetate and 1,1-diphenyl ethylene. Investigations indicate that all of them reveal certain optical-selective capability, but chiral C2-symmetric 2,6-bispyridine ligands show better catalytic capability than chiral asymmetric schifF-base ligands.

选择了2个手性2，6-吡啶双噁唑啉配体和6个手性不对称席夫碱配体与醋酸铜形成的配合物作为催化剂，对重氮乙酸乙酯与1，1-二苯乙烯不对称环加成进行催化反应，发现这8个催化剂对1，1-二苯乙烯的不对称环丙烷化反应都表现出了一定的光学活性诱导能力，手性2，6-吡啶双噁唑啉-铜类具有比手性Schiff碱-铜类更好的催化性能。

When both eyes view the red and blue images simultaneously, the cornea and lens of the eyes refract different amounts of the colors, which results in their systematic and symmetric binocular mislocalization. The brain deals with this sensory aberration by imagining depth—the red heart is in front of the blue background and vice versa—even though none actually exists.

当双眼同时看红色与蓝色图片时，由于系统的、对称的双目定位错觉，眼角膜和眼球晶状体会折射出不同数量的颜色，大脑将这种感官的偏差理解为影像的深度——红色的心在蓝色背景的前面而蓝色的心在红色的背景的后面——事实上并非如此。

Handle assembly of small irregular positive speaker, original handle cross-level vertical holes, all with the centro-symmetric.

组装手柄正面的扬声器小孔不整齐，原装手柄的小孔横平竖直，处处与中心对称。

From FEM, the contact stress obeys the semi-ellipse distribution and the Mises stress and shear stress are also consistent with contact mechanics theory, but there exists offset or deflection in the symmetric lines of stress distribution, which originates from tooth bending deformation.

由有限元方法得到的渐开线轮齿的接触应力符合Hertz理论中的半椭圆分布规律，Mises应力和剪应力分布也符合接触力学理论，但应力分布的对称中心存在偏离或者偏斜现象，分析认为，是由于轮齿弯曲变形造成的。

By observing the constructed membership functions, we learn that the human preference is not consistent with equal-weighted, equal-spaced numerical evaluations. Nor is it consistent with simplified, symmetric triangular or trapezoidal membership functions.

由观察所建构的归属函数显示：人类的偏好当转成模糊评估尺度时，与等权重、等间隔的数值评估或对称的简化型归属函数是不一致的。

To the outside, we mainly study an offer model in which one indivisible civil-engineering project of unknown construction cost is tendered to n tenders. The offer is not the sole decisive factor which decides who will get the contract, the tendering plan and the offer can play an important combinatorial role in the competition, and the winner's offer via the procedure of competitive bidding tends to the symmetric Nash equilibrium in both the probabilistic sense and the economic sense.

对外主要研究完全不合作的投标竞争环境下的n人投标报价决策问题，考虑到报价不是得标的唯一决定性因素，施工方案和工程报价为赢得工程施工合同共同发挥组合效应，一定条件下，报价趋于Nash平衡。

In this paper, we study the left color symmetric structures on Lie color algebras.

摘要本文研究了着色李超代数上的左着色对称结构问题。

On the other hand, patients with NIHL had chronic course of hearing loss, resulting from occupational noise, and their audiograms mostly showed symmetric, dip type hearing loss.

在听力检查方面，噪音性听力丧失大多呈dip型听力图，而听性外伤的听力图则表现不一，以高音急坠型的听力丧失为最常见。

The calculated results show that azido in azides has linear structure , the most optimized CaN6 has linear structure , and the most optimized (CaN6)n (n=2～5) clusters have chain structure of perpendicularity of approximate diamond composed by two azido with two Ca atoms . The middle N atoms of azido show positive, the N atoms at both ends of azido show negative, and the N atoms effected with Ca atoms directly show more negative . There is strong ionic bond between the Ca and N atoms. The IR spectra of the most optimized (CaN6)n (n=1～5) clusters have four vibrational sections , the whole strongest vibrational peak lies in 2195～2280cm-1,and the vibrational mode is anti-symmetric stretching vibration of N-N bonds in azido . Stability analysis show that (CaN6)3 and (CaN6)5 clusters are more stable than other clusters .

结果表明，叠氮化合物中叠氮基以直线型存在，CaN6团簇的最稳定结构为线型结构，(CaN6)n(n=2～5)团簇首先由两个叠氮基与两个Ca原子构成一个近似菱形，再由菱形相互垂直形成链状最稳定结构；叠氮基中间的N原子显示正电性，两端的N原子显示负电性，且与Ca直接作用的N原子负电性更强，金属Ca原子和N原子之间形成很强的离子键；(CaN6)n(n=1～5)团簇最稳定结构的IR光谱分为4个部分，其最强振动峰均位于2195～2280cm-1，振动模式为叠氮基中N-N键的反对称伸缩振动；稳定性分析显示，(CaN6)3和(CaN6)5团簇相对于其他团簇较为稳定。

Objective:To explore the feasibility of laparoscopy in diagnosing and treating of abdominal diseases.

The lifetime of nylon 1010 and nylon 1010/POSS composites decreased with increasing temperature.

热重-红外联用分析表明尼龙1010在氮气气氛下的降解产物主要为小分子的低聚物，POSS并不改变尼龙1010降解产物的组成。
