The absorption spectra indicate that the adsorption of dithiooxamide on the silver nanoparticles results in a red - shift in the spr band , mainly caused by the changes in the microenvironment of the metal nanoparticles and charge density alteration due to the charge transfer between the molecules and metal particles 吸收光谱结果表明银纳米粒子表面吸附二硫代乙二酰胺分子可导致金属粒子的表面等离子体共振吸收红移，主要与金属粒子的微环境改变以及吸附分子与金属间电荷转移而导致的金属粒子内部电子密度改变有关。
The electronic - ceramic capacitive - type sensor for coi is based on the nanometer and semiconductor theories . according to the mechanism of the gas surface absorbing actions and the mechanism of grain boundary effect of semiconductors , the capacitance of the sensor can be changed with the variation of co2 concentration Co _ 2气敏陶瓷电容型传感器将纳米理论和半导化理论引入了传感器的研制过程中，这种传感器通过气体表面吸附，及在半导体介质的晶界层产生的晶界效应，使得不同浓度co _ 2气体产生不同的电容值。
The oxide and reduce potential and the dopant concentration . the experiments of degradation methyl blue a1so showed that the photocatalytic activity could be greatly improved with vzos - loaded tio2 , maybe that loading v2o5 would accelerate the electron captured and charge transferring , change the samp1e surface hydrophilic and absorption 纳米tio _ 2 - v _ 2o _ 5复合光催化剂对次甲基蓝的降解实验表明，复合v _ 2o _ 5后tio _ 2可以加速电子捕获和电荷迁移速率，改变了样品表面吸附亲合力，使降解效率相比纯tio _ 2有很大提高。
When human serum albumin was adsorbed on the surface of au electrode or c12sh modified au electrode , different conformations were resulted and the processes of binding vepesid were also different . the corresponding kinetic parameters were obtained by fitting the response curves . the values of heterogeneous standard charge transfer rate constant for fe ( cn ) 637 fe ( cn ) 64 were obtained from the cyclic voltanimograms and the electrochemical impedance spectroscopy , and the electric double layer capacitance was calculated from the impedance semicircle 当在金电极及修饰了十二烷基硫醇的金电极表面吸附时， hsa以不同结合部位结合导致其吸附后的空间构象存在差异，在随后的与足叶乙甙给合过程中表现出了不同的结合行为，并拟合了相应的动力学参数。
Solvent replacement experiment provided direct evidence that there was water - rich adsorption layer and the reaction took place in the layer . the changes of the water in adsorption system were determined by kf - 1 water microdetector and from these data the volume of the adsorption layer on sio2 was calculated 首先用溶剂置换实验验证了纳米反应器的存在且是反应和粒子生长的场所；再结合卡尔?费休水分测定仪测定了吸附体系中水分的变化，计算了sio _ 2表面吸附层的厚度。
3 . metal supported on ti02 ( 110 ) : calculation and simulation chapter 4 , the properties of k , cu supported on the tio2 ( 110 ) surface have been studied by means of density functional theory , bare clusters models and embedded cluster model to using to obtain dft data and construct interatomic potential 3 .纳米二氧化钦负载金属体系的计算模拟研究我们对纳米金红石型tio :吸附k 、 cu金属原子进行了dft研究，并模拟了金属在纳米金红石型tio :表面的吸附行为，解释了纳米金属簇在金红石型tio :表面吸附的行为，预测了纳米金属团簇在表面生长的机理。
For the laser stream cleaning , the removing force is qualified by setting up a model , in which laser heats the medium film and produces bubbles in a film of medium near substrate surface , then the growing bubble impels the medium around it , at last the particles on the surface are removed by the rapidly moving medium 然后引入气泡成长动力学和流体冲击力学理论，解释了激光湿式清洗中微粒被去除的机理，建立了激光湿式清洗光学基片的动力学模型。试验的结果与模型分析的结论都表明激光湿式清洗能够有效去除表面吸附的微米甚至亚微米级的污染微粒。
