Excitations from localized states to the conduction band account for the absorption edge shift toward lower energies observed in the case of N/TiO_2 with respect to pure TiO_2.Mixture of visible light absorption of nitrogen doping and oxygen defect gave no obvious onset in the whole range between 400 and 800nm were observed of the samples N/TiO_(2-)A and N/TiO_(2-)M.

UV-VIS-DRS分析掺杂N/TiO_2结果表明，N/TiO_2-H和N/TiO_2-T两种催化剂在490nm处有吸收带边，可见光激发途径是掺杂的N以填隙方式形成的杂质能级吸收电子发生的跃迁引起的；而N/TiO_2-A和N/TiO_2-M两种方法得到的N/TiO_2在整个可见光区域内具有可见光吸收，没有显著的可见光吸收带边，其对可见光的激发途径是掺杂N和氧空缺共同作用的结果。

The main factors affecting the soil-structure interface behaviors were found experimentally and theoretically, including: 1 the thickness of the interface that is five to six times the average grain size of the soil; 2 the aeolotropy of interface, which is responsible for anisotropic response of the stress-strain response of the interface; 3 two physical states, including crashing and compression of the soil near the structure surface, which govern the stress-strain response of the interface strongly; 4 two shear deformation components due to sliding and constraint of the structure surface relative to the soil respectively, which forms the deformation of the interface; 5 the volumetric strain due to dilatancy, which is found to be composed of a reversible dilatancy component and an irreversible dilatancy component. 4. A unified constitutive model of the interface, based on new elasto-plasticity damage theory, was developed. It was confirmed to be effective for the conditions considering monotonic and cyclic shearing, coupling effect of shear and volumetric strains, evolution of physical state, micro-structure aeolotropy of the soil and the resulting aeolotropy of the interface as well as the three normal boundary conditions stated above. 5. 2D and 3D finite element formulations of the present model were derived and incorporated into the FEM codes. They were applied to the evaluation of practical engineering problems with different typical interfaces between soil and structure. The new model was shown to be reasonable and effective.

确定了粗粒土与结构接触面厚度约为5～6倍的平均粒径，首次揭示了接触面的细观结构异向性以及由此所引起的宏观剪切异向性，发现了在单调和往返剪切荷载作用下土颗粒破碎和剪切压密两种物态变化机制共同支配着接触面力学性质的变化，通过细观分析证实了接触面的变形可分解为一般同时发生的土与结构交界面上的滑移变形以及结构面位移约束范围之内土体本身的剪切变形两部分，观测到接触面受剪时表现出明显的相对法向位移，并可分解为可逆性和不可逆性两个分量；(4)建立了第一个能够统一地描述单调与往返剪切特性、剪应变与体应变耦合特性、细观结构和宏观剪切异向性以及土颗粒破碎等物态变化特性的土与结构接触面弹塑性损伤本构数学模型，并采用多种法向边界条件复杂加载路径的试验成果验证了新模型的合理性和有效性；(5)提出了新模型的二、三维有限元格式并结合实际边值问题进行了应用计算分析，比较了不同接触面本构模型对计算结果的影响，证实了新模型及其有限元格式不仅能够合理地描述土与结构接触面的主要力学特性，还能够较好地反映土体与结构物在接触面处的滑移、脱开等不连续现象。

The transmission spectrum and the absorption spectrum of alcohol shows that the characteristic absorption peak shifts with alcoholicity due to the molecular configuration. A multiple regression model was established based on the position, the intensity and the shape of the characteristic absorption peak, and used to detect alcoholicity. The predictive results show a linear relationship between predicted values and real values in sonic range, and can be used as a means to detect the alcoholicity.

通过对酒精透射光谱和吸收光谱的研究发现，其特征吸收峰随浓度不同发生漂移，从分子结构能级角度对其做了定性解释；根据部分稳定的特征吸收峰处不同波长点的吸光度，利用最小二乘法建立了多元线性回归模型，运用此模型实现了根据特征吸收峰波长的位置、强度、形状来预测酒精浓度，测定数据与样品浓度之间在一定范围呈良好的线性关系。

Experimental investigation indicates that shock wave velocity and shock wave pressure of beginning which were produced with aluminize RHTL were smaller than that of insensitive RDX in steel plate, however, attenuating velocity of shock wave velocity and shock wave pressure which were produced under contact explosion with aluminize RHTL were quciker than that of insensitive RDX in steel plate, when steel- plate had been separately operated under contact explosion with insensitive RDX and aluminize RHTL, and shock wave press had changed suddenly in the interface between steel and aluminum, In the circumstances, the shock wave velocity had ascended suddenly and shock wave pressure had descended suddenly.

实验研究表明：RHTL炸药爆炸加载钢板下，介质中的冲击波初始速度和初始压力相对RDX较小，衰减相对较快；钝化RDX和含铝炸药RHTL分别作用于钢铝复合板时，在分界面处冲击波速度和压力都发生突越，冲击波速度突跃，冲击波压力突降。

NBTI effects can also be influenced by ratio of signal and vacancy. The dynamic characteristics in NBTI degradation was revealed under action of negative and positive gate voltage, degradation can be recovered by positive gate voltage stress.

在负-正-负栅压交替作用下PMOSFET器件中会呈现退化-钝化-退化的动态作用过程，正栅压作用下的PMOSFET器件特性退化会有一定程度的恢复，这是由于在正栅压作用下NBTI反应产物逆向向Si／SiO〓界面处运动从而发生钝化作用造成的。

For the same reason, the Goos-Hanchen shift is negative for both the TE and TM polarization incident waves as the result of the negative pennittivity and negative permeability nature of NIMs served as the rarer medium when total reflection occurring at a PIM-NIM interface.

The results show that the most dangerous position is near the joint of two-level series-wound mechanism, in which the failure happened easily.

从模态分析的结果可知，传动机构各构件危险部位多发生在靠近两级串联机构相连处附近，其失效多发生在这些部位。

近十年先后在美国、日本、土耳其、印度、中国的台湾省发生破坏性地震，特别是美国(1994年，Northridge)和日本(1995年，阪神)发生的强烈地震对生命财产造成巨大损失，引起各国政府和社会各方面的广泛关注，也引起各国地震工程学者的高度重视，促使地震工程学者反思现行结构设计体系，现有的抗震设计理论无论其本身还是它在适应社会的需求方面都存在不足之处。
