The dependences of third-order optical nonlinear on the molecular structures of polymethine cyanines were thoroughly analyzed by introducing the simplified free electron model and the time-dependent perturbation theory.

对咔唑羰基铬配合物还观察到了来自金属到配体的电荷转移特征吸收带；(3)采用皮秒前向简并四波混频技术测试了所有目标分子的三阶非线性极化率、二阶超极化率以及非线性折射率等非线性光学参数。

Zinc diamyl dithiocarbamate antioxidant showed good synergism with antimony diakyl dithiocarbamate antiwear additive in improving the oxidation stability of modified soybean oils. The incipient oxidation temperature and induction period time of genetically modified soybean oils were improved significantly by adding polyalphaolefin and additives, and they were even better than that of the synthetic base oil PAO with the same additive formulation.

结果表明，改性大豆油的不饱和脂肪酸含量越高，其氧化安定性越差；抗氧剂二戊基二硫代氨基甲酸锌和抗磨剂二烷基二硫代氨基甲酸锑在改性大豆油中均表现出了良好的抗氧协同性能，尤其在基因改性大豆油中，聚-α-烯烃和添加剂的复配使其起始氧化温度和氧化诱导时间均超过了相同配方的聚-α-烯烃油样。

In this paper, we optimized the thickness of the doublers and triplers, mismatch angles and other parameters of Ⅰ/Ⅱ angle detuning and Ⅱ/Ⅱ polarization mismatch third harmonic generation schemes by numerical calculation way.

采用四阶龙格－库塔数值计算方法，以Ⅰ／Ⅱ角度失谐和Ⅱ／Ⅱ偏振失配两种三倍频方案为例，给出了入射基频光为平面方波，功率密度5GW／cm2的情况下，KDP晶体三倍频参数的优化结果。

The test result shows that, for the asphalt pavement structure with thick hot-mix asphalt course, the influence of flexible or semi-rigid base on pavement rutting is little and perpetual deformation occurs mostly on the top asphalt layer of 20 centimeter depth.

环道试验测定结果表明：对于本试验三种沥青层厚度超过20 cm的沥青路面结构，土基对车辙的影响很小，级配碎石柔性基层和水泥稳定碎石半刚性基层对车辙的影响也很小，路面永久变形主要发生在20 cm深度范围的沥青层内。

So far they have been synthesized with various substituted groups and cavity-size of 4-20 phenol units. Calixarenes have been utilized in fields of complexation, catalysis, extraction, ionophore and so on.

目前已经合成出了4-20个苯酚单元所构成的不同环腔尺寸和具有不同取代基的杯芳烃：它已在配位、催化、萃取、离子载体、分离材料等领域得到了应用，在色谱中的应用也日益受到关注。

The shoes also had a two-tone effect, and the swell of celestial voices in David Motion's "Buoyancy" on the soundtrack underscored the twisted religiosity. The bi-collar was a foretaste of what can only be described as a male bikini, which combined a bib front with what appeared to be a visible jockstrap (or maybe male garter belt?) and closed at the back like a waistcoat. Wags instantly dubbed the look "wedgie chic," but it was more disturbing than that—as if traditional concepts of masculinity had been turned inside out. Of course, this is something Miuccia's talked about for years, but it was still striking to see it rendered so graphically. Even more so when a couple of back-buttoning blouses walked past—male vulnerability wrapped up in a shirt.

这是本季男装戏谑趣味又颠覆传统的其一；仿似神职人员的double小领结及以两种色调呈现的皮鞋、再搭上伦敦著名作曲配乐家David Motion综合了圣乐与电子节拍的秀场主题曲&Buoyancy&，成功的带出Miuccia意欲传递给大家的矛盾和滑稽；更夸张傻眼的紧接而来：儿童使用的围兜（也很像中国古代女人的性感肚兜）配上男运动员专用的弹性下体护身、穿在合身的双领衬衫外，就活像是男性比基尼的外穿，然后转过身来，我们更看到，肚兜上衣的背后或交叉缕空的有如女人的性感马甲、或呈排扣有如女性内衣。

The influence of the distance from the ligands on the one-lectron energy levels are discussed.

讨论了配位体的距离对单电子轨道和基态组态的影响，也讨论了对称性变化的影响。

The stability constants for the new macrocycle and binary complexes of the amino acid with the macrocyclic ligand are reported.

大环多胺配体对各种小分子的识别与大环的腔体大小、环的刚性程度及环上取代基的性质有关。

The influence of ligand and cooperative metal on carbonyl insertion in heterobimetallic Rh-M species was investigated at the B3LYP level of density functional theory.

采用密度泛函方法研究了配体和协同金属对杂双核Rh-M金属配合物中羰基插入反应的影响。

The positive peptide cleavage promoted by complex, CuⅡL and the negative response of CuⅡ/dien complex suggest the merely hydroxy pendant in complex have no ability to attack the peptide bond. The synergic carbonyl activation by metal coordination is essential for the cleavage of peptide bond promoted by CuⅡL.

比较相应铜配合物及二乙烯三胺铜配合物的切割性能，提示羟乙基侧臂单独难以实现相邻肽键的切割，高配位数金属中心对肽键羰基的活化与羟基的协同进攻是该类配合物切割多肽的可能机制。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
