对称部分的

In the second part of the thesis,we study the symmetry group(point groupand its double group)of the polyatomic molecules.

在论文的第二部分，我们详细地研究了具有较大对称性分子的对称变换群及其物理应用。

This section of the circuit is symmetrical.

但数据线是双向的，且这部分电路是对称的。

In the field of visible photosensitive resin, the absorption spectrum, excited state, solvent polarity effect, fluorescence spectrum, fluorescence quenching, concentration effect, photo fading, reaction mechanism as well as photopolymerization kinetics of xanthene iodonium salts and cyanine dye-borate were discussed. It is found that under the radiation of visible light, intra-ion-pair electron transfer reactions occur in bis salt of fluorescein and unsymmetrical trimethine cyanines containing quinoline end group triphenyl-butylboron, and the fading rate is very high.

在可见光敏树脂部分，通过对呫吨染料碘鎓盐和菁染料-硼盐体系的吸收光谱性质、激发态性质、溶剂极性效应、荧光光谱、荧光猝灭、浓度效应、光褪色反应、光聚合动力学等的研究，结果发现：荧光黄双二苯基碘鎓盐体系和含喹啉环端基不对称三甲川菁染料-三苯基丁基硼盐体系在可见光作用下均发生离子对内电子转移反应，且光褪色反应速率很高。

In the forth part, in the presence of chiral phosphoric acid, highly enantio-enriched (up to 98% ee)α-aryl glycine derivatives could be synthesized via asymmetric transfer hydrogenation of the α-aryl imino esters using Hantzsch ester as the hydrogen source.

第四部分工作中，利用Hantzsch酯作为氢源，高对映选择性地实现了手性磷酸催化芳基酮酸酯亚胺的不对称仿生氢化反应，以最高98％的对映选择性得到苯甘氨酸衍生物。

The high impedance line part is disposed between the first low impedance line and the second low impedance line, and the input end and output terminal are asymmetrically arranged both sides of a syntonizer composed of the high impedance line, the first low impedance line as well as the second low impedance line.

高阻抗线部分设置于第一低阻抗线与第二低阻抗线之间，且输入端与输出端非对称设置于高阻抗线与第一低阻抗线以及第二低阻抗线所组成的谐振器的两边。

The third section: The novel method for synthesizing unsymmetrical sulfides was proposed.

第三部分研究内容：首次提出了不对称硫醚的新的合成方法。

The curve of the Ge is also highly standardized, and the 3 faces of the arrowheads are at perfect alignment.

戈的圆弧部分加工得十分规整，箭头上三个流线型的表面也完全对称。

The MSDs assemble to form a low conductance (6-10pS) anion-selective pore with deep intracellular and shallow extracellular vestibules separated by a selectivity filter.

MSDs构成一个低电导(6~12pS)的阴离子选择性孔道，其形状如同不对称的沙漏，胞外小胞内大，狭窄部分为离子筛。

Doing poineering work board market setting is asymmetrical go up drop stop board another of the system great sense is, can doing poineering work board implementation kind do trade for nothing, the part amends the malady of pattern of profit of stock market unilateral.

在创业板市场设置非对称涨跌停板制度的另一层重大意义是，可在创业板实现类做空交易，部分修正股票市场单边盈利模式的弊病。

Stability and local bifurcations of the fixed point of periodic impact are analyzed.

建立了两自由度含间隙振动系统对称周期碰撞运动的Poincar啨映射方程，讨论了该映射不动点的稳定性与局部分岔。

I will endeavour to find you some assistance.

我尽力帮你找人帮忙。

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
