The optimum reaction conditions and the influencing factors were studied. In the presence of gum arobic, arsenazo Ⅲ-barium in acid solution could combine with BSA to form a ternary complex leading to a redshift of absorption spectrum and significant increase of absorption peak intensity.

研究发现，在表面活性剂阿拉伯树胶存在下的酸性溶液中，偶氮胂Ⅲ-Ba配合物与BSA发生反应形成三元复合物，引起吸收光谱发生红移，吸收峰明显增高。

Two models have been proposed to explain molecular mechanism of Dkk's inhibition role in canonical Wnt pathway: in the first model, Dkk1 competes for binding of Wnt co-receptor LRP6; in the second model, Dkk1 can form a ternary complex with LRP6 and Kremen at the presence of Kremen, and triggers the endocytosis of this ternary complex quickly. The controversies between these two models exist during these years.

现今有两种模型分别解释Dkk抑制经典Wnt信号的分子机制：在第一种模型中，一些研究者认为Dkk1主要通过在细胞外与配体Wnt竞争受体LRP6从而抑制Wnt信号；在第二种模型中，另一些研究者们则认为在Kremen存在的情况下，Dkk1通过诱导形成Dkk1-LRP6-Kremen三元复合物，并迅速诱导这个三元复合物的内吞从而发挥抑制功能。

You might as well try the following methods:When the senior is out,invite a testifier,of course,you can't find it to the eye,this must be intentionally.For example,carry it out at the presence of miss secretary,your intention is to let someone know the cause and effect of the hole things,make workmates know the fact.One passes on message to ten,ten passes message to one hundred.

不妨试试以下方法：上司不在时，请来一个见证者，当然不是公然地找，而是有意无意，例如在秘书小姐面前进行，目的是要有人知晓整件事情的来龙去脉，使公司里人晓得真相。

The presence of the strong absorption band around 220nm in UV-Vis spectra and the appearance of the band around 960cm^(-1) in IR spectra demonstrate that the tetrahedrally coordinated Ti-atoms exist in the framework of Ti-containing zeolites.

UV-Vis光谱在220nm处的强吸收峰和骨架在960cm-1处的红外吸收峰均证明在沸石骨架中存在四配位Ti原子。

The OnTrak TesTcard 9 provides a qualitative screen for the presence of amphetamines, barbiturates, benzodiazepines, cocaine, methamphetamines, morphine, phencyclidine, tetrahydrocannabinol, and tricyclic antidepressants in urine.

OnTrak TesTcard 9能够定性筛查下述尿液中的药物：安非他明、巴比妥酸盐、苯二氮、可卡因、脱氧麻黄碱、吗啡、苯环己哌啶、四氢大麻酚、三环抗抑郁药。

The copolymers are oxidized with hydrogen peroxide in the presence of osmium tetroxide. It is confirmed by superscript 1H-NMR and FTIR that the double bonds in the molecule chains of the copolymers are fully oxidized, while the segments of polystyrene in the copolymers are kept intact.

采用双氧水在四氧化锇催化下对聚合物分子链进行氧化降解，1H-NMR和FT-IR分析表明共聚物中的双键被全部氧化并发生断裂，而共聚物中聚苯乙烯的链节并未被破坏。

The textural feature is used to roughly evaluate the presence of moving targets in a region.

提出基于纹理特征及统计学模型的背景提取方法来完成背景的稳健提取和实时更新。

By this time the Curies were so certain of the presence of the new element that they wondered what name it should be given--what it would look like.

至此，居里夫妇确信这种新的放射性元素的确是存在的，他们开始考虑为这新元素命名——它看起来是怎么样的？

The shaping method of noncircular part and the tool holder's radial motion characters in noncircular turning process are discussed in detail in the thesis.

论文详细研究了非圆零件的成型方法和加工过程中刀架的径向运动规律。

I have not really liked him,I do not like his this kind of disposition.
