For both series of heteroleptic tris rare earth compounds, the characteristic phthalocyanine dianion IR bands for Pc2- and O OPc2- at ca. 1329 and 1380 cm-1 attributed to the pyrrole stretching and the symmetric C-H bending of -CH3 groups in octyloxy side chains of OOPc rings together with some small contribution from the isoindole stretching vibrations,re specteively,are simultaneously found in their IR spectra.

在这两个不对称三明治型稀土配合物系列的红外光谱中发现了这样一种特性，即酞菁阴离子Pc~(2-)和OOPc~(2-)的特征波段在1329cm~(-1)和1380cm~(-1)之间，这是因为吡咯的伸缩振动和OOPc环中八烷氧基侧链上-CH_3基团的对称C-H的弯曲振动共同作用于吲哚环的伸缩振动。

3A series of C_2-symmetric chiralβ-amino alcoholsⅢ-6 andⅢ-10were synthesized in several steps from natural amino acids,and applied in the asymmetric borane reduction of prochiral ketones.The catalytic activity ofⅢ-6 was better thanⅢ-10.

3以天然氨基酸为起始原料，经过简单的几步反应合成了开链冠醚类C_2-对称的手性β-氨基醇Ⅲ-6以及Ⅲ-10，将其应用于硼烷对前手性酮的不对称还原反应中，含有脯氨醇结构单元Ⅲ-6的催化效果要好于由其他氨基酸衍生的Ⅲ-10，THF为溶剂，回流，催化量为10 mol%时，最高得到85%的ee值。

The shoe boots of this kind of design broke semmetry and balanced modelling principle, do one's best helps the change of type design, with popularity slant head last for shaping a shoe close suitably, with modelling of asymmetry of a kind of reduplicative, make whole shoe money bring out the best in each other.

这种款式的鞋靴打破了对称与均衡的造型原则，力求帮样款式的变化，与流行的偏头鞋楦相配合，以一种重复的不对称造型，使整个鞋款相得益彰。

Crystals of pure quartz, usually called rock crystal, are coarseness, colorless, transparent.

答案：D分析及考点：平行对称结构，词性不对称，所以8ttt8 coarseness名词应改成coarse参考译文：纯净石英的结晶，通常称为岩石水晶，是粗糙的，无色的，透明的。

Lenses are optical elements with 2 refractive surfaces. These can be centered sphericalally, rotationally

这些透镜是有中心的，如球面的或旋转对称的，而不是非旋转对称的。

The discrete-element modeling is a new dynamic modeling method in structural geology and geophysics research. The authors built a discrete element model to simulate the evolution of the fault system in active salt domes. Results show that the fault system undergoes three stages: symmetric deformation stage, asymmetric deformation stage, and complete fracture stage.

离散元模拟是构造地质地球物理研究中一种新的动力学模拟方法，作者通过构建离散元模型，模拟了主动底辟盐构造断裂系统的演化过程，结果表明，该断裂系统的发育主要经历了对称变形、不对称变形、整体破裂三个阶段。

Fluctuating asymmetry, defined by random, stress-induced deviations from perfect bilateral symmetry, is an indication of the inability to buffer against developmental disturbances, such as poor early nutrition.

波动不对称是压力的随机性引发双侧完美对称偏离的现象，这是个体无力免受发展中不利因素侵害的一个标志。

Flatfish, such as the flounder, are among the few vertebrates that lack approximate bilateral symmetry (symmetry in which structures to the left and right of the body's midline are mirror images).

鲆鱼，例如比目鱼，是少数左右两侧不太对称的脊椎动物之一（左右两侧对称指的是身体中线左右两边的结构为镜象反射）。
