In this paper, we investigate the light intensity-dependent superprism phenomenon in the two-dimensional Kerr nonlinear photonic crystal by nonlinear finite-difference time-domain technique. We show that when the intensity of the self-pumping beam is increased from 70 to 300 W/μm , the refraction angle of the beam can be tuned about 10 degree.

基于非线性时域有限差分法，我们模拟了克尔非线性光子晶体中的光敏超棱镜现象，结果发现，当光强变化230W/μm时，两束光在空间上能被分开10o，选取较大的基本功率将有助于提高其光强分辨率，。

In this thesis,based on the DFT+NEGF first-principles method,we construct a lead-molecule-lead sandwich system with single benzene-based molecule to investigate the relationship between the structure and properties of the molecular devices and the factors that influence properties of the molecular devices.Our computational investigations on these molecular devices are primarily concentrated on the effect of contact geometry between molecules and electrodes,the effect of side groups,the effect of different torsion angle between two phenyl rings and the effect of external electric field.This thesis consists of five chapters:In Chapter one,we mainly introduce the research background and development of the molecular electronics,including the experimental fabrication of molecular electronic components and theoretical simulation methods.Afterwards we discuss the questions that need to be solved in this area.Finally,the main contents of this thesis are listed.In Chapter two,we introduce the theoretical methods used in this thesis, including the main first-principles calculation methods,i.e.,the Density-Functionmethod and nonequilibrium Green\'s function.

objective to investigate the clinical therapeutic effect of mucosolvan nebulization in infants with pneumonia.methods 96 infants were randomly divided into and control group.regular treatment were given to control group,meanwhile,based on regular treatment,the infants in observation group were also received mushutan nebulization.the disappearing time of cough、wheezy phlegm、anhelation、wheezy sound in lung and admission duration were evatated.results the disappearing time of wheezy phlegm、wheezy sound in lung and admission duration in observation group were shorten than in control group(p.05).conclusion mucosolvan nebulization can raise clinical therapeutic effect for pneumonia in infants with pneumonia.especially in eliminating phlegm and disappearing of wheezy sound in lung.

摘要］ 目的：为探讨沐舒坦雾化吸入辅助治疗婴幼儿肺炎的效果。方法：将96例婴幼儿肺炎随机分成两组，两组均在常规抗感染，纠正缺氧、酸碱平衡、电解质紊乱，治疗组加用沐舒坦雾化吸入，对照组用α糜蛋白酶、地塞米松雾化吸入。对两组的咳嗽、痰鸣、气促、肺部湿音的消失时间及住院时间进行比较。结果：使用沐舒坦雾化吸入的治疗组在治疗痰鸣、肺部湿音消失时间及住院时间比对照组短（p.05）。结论：沐舒坦雾化吸入可提高婴幼儿肺炎治疗效果，尤其祛痰和减少肺部湿性音的效果较好。
