The problem in using titanium dioxide as a photocatalyst is recombination of electron and hole. One strategy for inhibiting theirs recombination is to add other electron accepters to the reaction. It can reduce the electron/hole recombination and then produce more ·OH on the surface of titanium dioxide, from which increased the degradation rate of the pesticide.

二氧化钛作为光催化剂进行光催化降解的问题在于电子—空穴对的重新复合，抑制其重新复合的一种办法是加入其他的电子接受体，减少电子—空穴对的复合，从而使光催化剂TiO2表面产生更多的·OH自由基，加强农药的光催化降解。

在经典的氢原子模型里，电子绕着原子核作圆周运动，在经典的氢原子模型里，电子绕著原子核作圆周运动，就象地球绕太阳运动一样就就像像地球绕太阳运动一样地球绕太阳运动一样，，只只是前者的是前者的而其引力来自电场。

The results indicate that the electron loss timescales due to artificial injection of ELF/VLF waves in the inner and the outer radiation belts depend largely on the value of the cold-plasma parameter α*(∝ B 2/ N 0, where B is the ambient magnetic field and N 0 the electron number density), the properties of wave frequency spectrum, the wave power and the electron energy in resonance with the waves.

数值计算结果表明，在内、外辐射带由于ELF/VLF波的人工注入而造成的高能电子损失时间尺度很大程度上取决于冷等离子体参量α*(∝ B 2/ N 0，这里 B 是背景磁场， N 0是电子数密度)、电波频谱特性和功率，以及与波发生回旋共振的电子能量。

Based on Stuart et al.'s electron density evolution equation, the electron density evolution process in fused silica film irradiated by short-pulse laser for τ∈[0.015] ps were studied by means of numerical method. The effects of initial electron density N and laser pulse width τ on laser threshold intensity I and damage threshold fluence. F were analyzed respectively.

The electron location function shows the electronic density changes at both the atomic vacancies and antisites. There is an obvious absence of electronic areas where the vacancy of Ga has the dangling bonds of N, which are favourable for the sdsorption of metal atoms. In contrast, at the vacancy of N, there is more electron distribution(ELF:0.16-0.45), forming lone electron pairs which are profitably available to combine electronegative atoms.

电子局域函数显示了表面空位和替位处的电子密度变化，表面Ga原子空缺处有非常明显的缺电子区域，悬挂键临近N的电子密度增大，有利于对金属原子的吸附；N原子空位处的ELF值为0.16-0.45，有利于同电负性较大的原子结合。

The dissertation is concentrating on the topic of a high power, tunable, millimeter wave free electron laser. The tunable ability of the mm wave FEL is studied. FEL powers are improved by novel variable parameter wigglers. A high brightness electron beam is achieved for FEL. These technologies are very important for realization of high power compact free electron lasers.

Based on the structure, those human diseases related mutation sites are mapped onto the structure accurately. As a result, it is found that these sites are all around the electron transfer prosthetic groups or ubiquinone. And these mutations will alter prosthetic groups' binding or ubiquinone's binding, causing electron leakage from the prosthetic groups in the electron transfer chain, producing reactive oxygen species and leading to tumor formation.

利用线粒体复合物 II 的结构对已知与人类疾病相关的该复合物突变位点进行了精确定位，发现这些突变位点均位于电子传递体或辅酶 Q 结合位点的周围，它们的突变或影响了电子传递体的结合，或影响了辅酶 Q 的结合，从而导致电子传递的中断，电子逃逸到线粒体基质中或线粒体内膜中，经过一系列下游途径导致疾病的产生。
