离子结合

Except for this, the others such as ionic bridge (e. g. Me〓, I〓), appositional replacement and destroying the binding site etc. is involved in also. 5. The type of BSA intrinsic fluorescence being quenched is mainly static quenching, and the nonradiative energy transfer is attributed to BSA intrinsic fluorescence being quenched also.

各种类型的外加剂对中药小分子-蛋白质作用过程的影响方式各不相同，与BSA结合引致BSA分子构象改变是外加剂参与并影响中药小分子-BSA相互作用过程的共通机制；除此共通机制外，还可能存在离子架桥、同位取代以及对BSA分子上药物结合部位的破坏等作用形式。

Copper clad steel grounding pole is made by special electroform technique that is using 99.9% pure copper cover on the core of mild steel equally, which makes the copper and steel core entirely molecule bond (if not bonding tightly , the primary battery reaction will occur when electrifying,anode metal iron generates oxidation reaction to be iron-ion and losing, it accelerates the corrosion of steel core).

铜包钢接地极是用特殊的电铸技术将99.9%的纯铜均匀覆盖到低碳钢芯上，使铜与钢芯完全分子结合（如两者结合不密，在通电的情况下，会产生原电池反应，阳极金属铁发生氧化反应变成铁离子流失，反而加快钢芯受蚀）。

In addition, the 10 peptides are rich in basic amino acid residues and serine and threonine, it is likely that the peptides combine with iNOS FAD binding domain through formation of ionic bond and hydrogen bond.

因此，这些多肽很可能通过与iNOS的FAD结合区的酸性氨基酸形成离子键，以及通过丝氨酸或丝氨酸的醇羟基与酶分子的有关部位形成氢键而结合并起到抑制作用。

Crystal lattice constants are close to other experiment results. Three kinds of chemical bonds exist among Mg and B atoms, between magnesium and boride is ionic bond and metallic bond is the predominant interaction in the layer formed by magnesium atoms. A strong covalent bond in the form of sp2 hybrid between boride atoms is the most important factors which can affect the transition temperature of MgB2. Population analysis clearly shows that electrons are transferred from Mg to B, as a result, the electron-phonon coupling in the layer of B is very strong.

规范保守赝势的计算结果表明，晶格常数与实验值误差在很小的范围内，分析了引起MgB2(001)面结构超导转变时电子浓度和偏态密度的变化情况，发现构成该超导体结构的成键有3种，着重从结构的电子浓度变化分析了其超导特性，六角蜂窝状结构中硼原子间相互作用为sp2杂化的共价键，镁原子和硼原子之间是离子键结合，镁原子层是金属键结合，镁原子的价电子部分转移到硼原子的pz轨道，部分电子为镁原子层共用。

The choice recurs the natural incisive condyloma patient 120 examples stochastically to divide into the treatment group 80 examples,the comparison group 40 examples,uses GX-Ⅲ multi-purpose electricity ion surgery therapeutic machine unifies these two method of treatment with the cooperation of Chinese and Western medicine and the western medicine and the partial treatment separately to carry on the treatment.

选择复发性尖锐湿疣患者120例随机分成治疗组80例、对照组40例，采用GX-Ⅲ型多功能电离子手术治疗机与中西医结合和西药与局部治疗相结合这两种治疗方法分别进行治疗。

Methods Proteins existed in adult Schistosoma japonicum membrane were extracted by Triton X-100 and purified through reverse-phase high performance liquid chromatography,and the main protein peaks were then collected separately. 125 I-LDL of human plasma as the ligand, through the radioautography and radioligand binding assay, the protein which can bind human serum 125 I-LDL specifically was identified.

自人工感染家兔的肠系膜下静脉取日本血吸虫成虫，用非离子去污剂TritonX 10 0抽提出日本血吸虫成虫表膜蛋白，反相高效液相色谱进行分离纯化后，收集各主要分离蛋白峰，以12 5I标记的人血浆低密度脂蛋白作为放射性配体，经放射性自显影及放射性受体配体结合分析鉴定能与人血浆12 5I LDL特异结合的蛋白。

The RRS intensity was enhanced obviously after the drugs and DNA reacting with each other, which indicated the formation of new products for the maximum peak appeared at around 375 nm with slight red shift. Then the Cu ion was added into the system to form a ternary system, and the RRS intensity was enhanced significantly, when the enhanced spectral value was directly proportional to the concentration of the DNA. Thus a highly sensitive method could be obtained for determining DNA and the detection limit of the experiment reached 9.7 ng/mL for the RFSV system.

两者反应形成结合产物后其RRS明显增强，并在375 nm左右出现最大散射峰，且有不同程度的红移和散射增强，说明两者结合成新的产物；加入Cu2＋离子后， Cu2＋与利福霉素抗生素及DNA形成三元复合物，此时将导致RRS进一步剧增，而且RRS光谱增强值与DNA浓度呈正比，因而可用于DNA测定具有较高的灵敏度，实验对ctDNA的检出限为9.7 ng/mL (RFSV-Cu2＋- ctDNA体系)。

The influence of Cuon the combination between LMX and BSA was studied as well,the binding constant between LMX and BSA was decreased in the presence of Cu,consequently,the interaction between LMX and BSA weakened.

并且讨论了铜离子对两者结合的影响，Cu的存在降低了LMX与BSA之间的结合常数，使洛美沙星与BSA的作用变弱。

The results in this paper are concluded as follows:(1) Rolling contact fatigue has been used to examine the interfacial reaction products and study the mechanism of ion beam intermixing effect on the adhesion of Cr-N coating on steel by IBAD.
