When the resulting nitro compounds was reduced over 5% Pd/C catalyst, the nitro phosphinic acids required more catalyst that the esters nitro phosphinic acid, and dinitro compounds required more catalyst than mono-nitro compounds in the case of all nitro groups completely changed into amino groups.

用5％Pd/C作催化剂，将上述硝基物还原时发现，次膦酸形成的硝基物比次膦酸酯形成的硝基物需要更多催化剂才能使硝基全部还原成氨基；二硝基化合物比单硝基化合物需要更多的催化剂。

Further study of the interaction between NodD and naringenin by FRET technology is underway.

通过对naringenin分子上六个不同位点，不同性质，长度连接链以及母体和荧光团之间两种连接方式的11个荧光标记物的合成以及生物活性评价，我们找到了一个荧光标记物，它保留了野生型naringenin约20％的活性，并将其用于根瘤菌固氮过程的研究，发现该荧光标记物能够顺利进入根瘤菌活细胞中，为下一步通过FRET技术研究naringenin和NodD蛋白之间的相互作用打下了基础。

Most of the substances in the deposit were the nonsticky calcium carbonate and fines that could adhere to the sticky contaminants and deposit together, resulting in a great deal of the deposit.

对福建南平纸厂网前压力筛处的胶粘物进行分离和分析发现，以聚醋酸乙烯酯和聚丙烯酸酯为代表的人工合成聚合物以及机械浆中的木材树脂是产生胶粘物的根本来源，但它们在胶粘物沉积中的含量只有5%左右。

It has been reported that the leaf and root extracts of Petasites hybridus relieve gastrointestinal pain, lung-disease such as asthma and cough, as well as spasms of the urogenital-tract, and even suppress the proliferation of human T24 bladder carcinoma cells. In 2000, S-petasin had been found to decrease the testosteron releasing by rat testicular interstitial cells.

此植物体及其萃取物应用在治疗使用上已约有两千年的历史，在1994年的研究中指出其粹取物对於人类膀胱癌细胞株（T24）具有抗增殖的效果，且於2000年，本实验室研究发现其粹取物-硫蜂斗菜素具有抑制大鼠间质细胞分泌睪固酮的效用，然而它对於人类前列腺癌细胞株是否也会造成毒杀效应，目前则尚未有文献探讨。

It was found that La〓 does not affect the binding affinity between calmodulin and Polistes Mastoparan, a known calmodulin binding peptide, neither the conformation of the ternary complex. Excessive amount of La〓 result in the decrease of the binding constant and the disrupted conformation. The binding affinity of La〓 to calmodulin increased in the ternary complex (La〓-CaM-Mas/Mas X), which suggested the coordination between the two global domains. The binding priority between the two global domains is also changed: La〓 more is likely to bind to the C-terminal of calmodulin than to N-terminal, thus facilitates the binding of Mas/Mas X to the C-terminal of calmodulin as the first step of the Mas/Mas X binding.

在以钙调蛋白结合肽—Polistes Mastoparan和Mastoparan X为对象的研究中，我们发现，除非过量，否则La〓的存在不影响钙调蛋白与Mas间的结合常数以及构象；过量的La〓（La〓/CaM摩尔比＞4）将引起钙调蛋白结合功能的下降，同时明显改变金属-钙调蛋白-Mas三元复合物的构象；La〓对Ca〓CaM-Mas的N末端表现高度选择性，显示了在三元复合物中两种离子间的协同效应；在三元体系中，La〓与钙调蛋白的亲和力明显上升，而且亲和力上升的程度因钙调蛋白结合肽的不同而有明显差异，显示了作用的选择性；Mas和MasX的存在改变了La〓在钙调蛋白上的结合顺序，La〓很可能优先与C末端结合，从而使Mas/Mas X首先与C末端结合，该顺序与钙离子相同；La〓的参与使三元复合物在动力学上更加稳定。

Gliadin observed secaline specific band in the offspring and its father Lanxiaohei. Screening with 6 pairs of SSR primers on the long arm and short arm of 21 chromosomes, respeetively.

筛选小麦21条染色体长短臂上各6对引物，结果发现只有IBS上的3对引物未扩增出IBS的条带，其余引物均扩增出了各自的相应条带。

We also found that, stress concentrated at the symphyseal area of superstructure during opening movement, and separating the superstructure at the symphyseal area will decrease the stress concentration of implant prostheses.

比较不同赝复物对下颚形变的影响，结果发现赝复物若跨越下颚中心联合处，则会造成下颚形变量变小，且跨越下颚中心联合之赝复物越短，对下颚骨的形变限制越大。

Results suggested that Terminalia catappa leaves have no effect on cell viability of SCC-4 cells. The modified Boyden chamber assays revealed that a treatment of Terminalia catappa leaves significantly inhibited the cell motility/invasion capacities of SCC-4 cells.

在本实验中，利用 50%酒精萃取的榄仁树的叶之萃取物处理 SCC-4 细胞株，并利用 MTT assays 分析方法显示榄仁树的叶萃取物并不会影响 SCC-4 细胞的存活率，而当癌细胞转移时常常会伴随著细胞外基质的分解及细胞移动能力的改变，接著我们利用 modified Boyden chamber assay 发现榄仁树的叶萃取物具有抑制 SCC-4 细胞的移动与侵袭能力。

Finally, two tetranuclear Cu~(2+) complexes were constructed from a new salen ligand with alkoxo groups. The two complexes were obtained by the reaction of the same ligand with Cu~(2+) in different solvents, i.e., a stage tetranuclear complex and a pseudo-cubane tetranuclear complex in MeOH and THF, respectively.

最后，本文以Schiff碱类过渡金属配合物发展应用为研究背景，设计并合成了一种新型Schiff碱及其两种构型的Cu金属配合物，发现所设计的具有和三个Schiff碱配体，与Cu_2在不同的反应溶剂中进行配位反应时，可以得到不同结构的配合物。

The carboxyl of the tripodal ligand is a goodbridging group. The building blocks are linked together by the bridging group andother weak interactions (hydrogen bond and π-π stacking interaction, etc), thusgenerating a one, two or three-dimensional metal complexes.2. Studies on the fluorescence properties of the lanthanide complexes indicated that:(1) The excitations in the ligand-based π-π〓 transitions cause the structuredemission of lanthanide complexes while the ligand luminescence is completelyquenched showing that ligand-to-metal energy transfer occurs.

三脚架配体所带的羧基是一个很好的桥联基团，配合物的结构基元通过这种基团的桥联作用及其它一些弱的作用力(如氢键、π-π堆积作用等)联系起来，构成了一维、二维或三维的超分子空间结构。2、稀土配合物的发光研究发现：(1)用配体的π-π〓跃迁波长进行激发，配合物均显示出稀土离子的特征发射峰，同时，配体的荧光峰没有出现，这说明在三脚架配体与稀土离子间进行了有效的能量传递。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。
