对称的

Four symmetrical and asymmetrical pyrylium - squarylium cyanine dyes were synthesized.

合成了四个对称及不对称含叔丁基吡喃鎓方酸的菁染料，通过光谱和元素分析确定其结构，测定了它们的紫外-可见吸收光谱、熔点和溶解性能。

Necessary and sufficient conditions for the matrix equation to have symmetric positive semidefinite solutions are derived using the generalized singularvalue decomposition.

利用广义奇异值分解导出了该矩阵方程有对称半正定解的充分必要条件，并且给出了一般对称半正定解的表达式

As a corollary ,we prove the nonexistance of cubic semisymmetric graph of order 12p,i.e.,for all edge-transitive cubic graph of 12p is symmetric.

本文通过对12p阶3度边传递图的全自同构群的研究，证明了12p阶3度半对称图不存在，即任意12p阶边传递图必为对称图。

However, the fuller study of symmetrical and unsymmetrical charactristics lies outside the scope of this paper.

由於其空间组织中之对称与非对称特性的更完整研究属於此篇论文的范围之外。

The Chinese botanical garden completely is different, also does not ask the spool thread to be symmetrical, also does not have any rule to be possible to follow, on the contrary is actually the mountain surrounded by water hugs, winds windingly, not only flowers and plants trees, no matter what original condition of the nature, even if constructs artificially also as far as possible complies with the nature, but is irregular, makes every effort with the nature fusion.

西方园林所体现的是人工美，不仅布局对称、规则、严谨，就连花草都修整的方方正正，从而呈现出一种几何图案美，从现象上看西方造园主要是立足于用人工方法改变其自然状态。中国园林则完全不同，既不求轴线对称，也没有任何规则可循，相反却是山环水抱，曲折蜿蜒，不仅花草树木任自然之原貌，即使人工建筑也尽量顺应自然而参差错落，力求与自然融合。

Parametric design programs of the total tooth models of unsymmetric and symmetric involute gears were developed by Autolisp language, and the total models were transferred into ANSYS and calculated by finite element method.

用Autolisp语言开发了非对称与对称齿轮全齿模型的参数化设计程序，将生成的全齿模型导入ANSYS进行有限元分析。

The antipathies, I think--'(she was rather glad there WAS no one listening, this time, as it didn't sound at all the right word) '--but I shall have to ask them what the name of the country is, you know

爱丽丝对&地球对面的人&的概念模糊，以为他们是&头朝下&走路的，而且把&对跖人&错念成&对称人&了。吧？&这次她很高兴没人听她说话，因为&对称人这个名词似乎不

A discussion forum on human rights in Beijing, with participants hailing from different parts of the world.

其中有关体态语言的一些对称成语，确实能让人领会到对称美在英语中的体现。

The preliminary result shows that we can find new potential symmetries for thescalar equation by different F and G.

初步研究结果表明对F和G取某些值后，该方法得到的对称是原方程新的势对称。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
