关于“光源非单色性对干涉条纹的影响”的几个问题的探讨

光波波长连续分布与不连续分布对干涉条纹的影响不同,应区别分析;在杨氏双缝干涉实验中,由于光源的非单色性而引起的干涉条纹位移极小,肉眼不可分辨,因此以杨氏双缝干涉实验为例去谈光源的非单色性对干涉条纹的影响是不恰当的.     

家庭收入分析

本文应用计量经济学的方法,建立家庭收入的数学模型和家庭收入的分布函数。分析影响家庭收入的主要因素,同时确立家庭收入与其主要影响因素之间的定量关系。然后,把家庭收入拟合于三参数的对数正态分布,并用迭代的方法求出分布的参数。     

Social Justice Becomes a Living Experience for Students,Faculty, and Community

This social justice course was the result of a service‐learning project with African American and First Nations peoples of a Southern community telling their story of desegregation through the creation of a video documentary project. Combining the pedagogy of service‐learning with documentary video making, a social justice project was created that impacted students, faculty, and community.     

Listening to teachers–listening to students: substantive conversations about resistance,empowerment and engagement

This article examines contemporary research and debates about pedagogies of engagement that challenge the traditional assumptions and understandings of engagement. Three contesting epistemological constructions of student engagement are identified and examined through the contesting and resisting voices of teachers and students. The article's research suggests that an empowering and resistant pedagogy can (re)conceive student engagement so that it achieves the twin goals of social justice and academic achievement.     

负载型催化剂研究中的自发单层分散原理

许多负载型催化剂的活性组分可在载体表面自发分散。当活性组分含量低于其分散阈值时,它在载体表面呈单层但非密置单层分散,逾此阈值时出现晶相。自发分散效应可以称为自发单层分散原理。对自发单层分散原理的实质等问题作了初步探讨。     

和谐社会视角下的社会公平问题探讨

构建社会主义和谐社会必须注重社会公平问题。社会公平是社会主义和谐社会的基本特征和价值取向。构建社会主义和谐社会必须完善社会主义分配制度,建立全方位的监督体系,保障社会成员机会平等,以维护和实现社会公平。

Vapor-liquid equilibrium simulation of binary and ternary mixtures of CH4, C2H4 and iso-C4H10

The vapor-liquid equilibrium（VLE） properties for the binary and ternary mixtures of CH4,C2H4 and isoC4H10 are of great importance in the recovery of ethylene from mixture containing CH4 and C2H4 with iso-C4H10 as solvent.Hence,Gibbs ensemble Monte Carlo（GEMC） simulations were used to estimate vapor-liquid equilibrium for the binary and ternary mixtures of CH4,C2H4 and iso-C4H10 with the united atom potential NERD model.The selected simulation conditions are based on the experiment in the literature.The results of this work were shown to be in satisfactory agreement with available experimental data and predictions of Peng-Robinson equation of state.The structure of simulated liquid phase is also characterized by radial distribution function（RDF）,which contributes to further understanding of the VLE curve of these systems.RDF is not sensitive to the pressure and temperature range.With the increase of pressure or the decrease of temperature,the molecules tend to gather together.     

沉默权的程序正义价值探究

沉默权制度自萌芽到成熟历经几个世纪,它的发展经历了从开始确立到有所限制的两个阶段.对于沉默权制度我国学界是众说纷纭,从一开始的是否引进沉默权的论争到现在已经演变成了如何引进沉默权的问题.虽然近来新修定的刑事诉讼法中仍然没有确立沉默权制度,但其程序正义价值毋庸怀疑.现代刑事诉讼法基本原则之一的无罪推定原则,要求赋予犯罪嫌疑人、被告人以沉默权.沉默权制度的确立有助于保障犯罪嫌疑人、被告人的基本人权,从而加强辩护方的防御力量,实现诉讼中的控辩平衡,它是贯彻正当法律程序原则和实现程序正义的基本保障.
