PSpice对单管放大电路的几种仿真分析

PSpice是一个通用电路仿真程序,可用来对电路进行各种分析,包括直流工作点和直流传输特性分析、交流小信号分析、瞬态分析、傅立叶分析和通用参数扫描分析等。单管放大电路是组成各种复杂放大电路的基本单元,本文以单管放大电路为例,阐述了运用PSpice的几种最重要、最常见的分析功能:直流、交流小信号分析和瞬态分析,另加傅立叶分析和通用参数扫描分析。     

中国教材分析:历程回顾与未来展望

教材分析是指基于分析主题,选择合适的方法对教材文本进行分析,以总结教材的特点与规律,发现教材编制过程中存在的问题,并提出改进建议的过程.教材分析主题包括通用性分析主题和具有学科特色的分析主题;教材分析类型有单一版本教材分析、横向教材比较分析和纵向教材演变分析;教材分析方法集中于内容分析法和比较分析法.整体来看,教材分析发展呈现良好态势,但仍存在对教材分析的认识有待深化、教材分析缺乏双向对话理解、部分研究选题过于关注细枝末节,以及高质量教材分析成果数量不足等问题.未来需要加大教材分析理论研究、积极与教材编写者对话、多视角构建研究选题.

浅谈单位预算会计分析

会计分析是会计管理的重要组成部分,长期以来,单位预算会计分析工作是比较薄弱的。分析的内容只着重于会议报表（主要是年终决算）,作事后分析,这就削弱了预算会计分析的积极作用。笔者认为,会议分析应贯穿在单位预算资金运动的全过程,它应包括预算（计划）曲分析——事前分析;预算执行过程的分析——事中分析;预算执行结果的分析——事后分析。     

英美分析教育哲学的涨落--基于分析哲学与分析教育哲学关系的探讨

20世纪50-70年代,英美教育哲学的主流是“分析教育哲学”。分析教育哲学在50年代异军突起,60年代盛极一时,70年代日渐式微。分析教育哲学与分析哲学存在“血缘”关系：分析教育哲学的特征与分析哲学在教育领域中的运用息息相关,分析教育哲学遭受诟病与分析哲学受到批评息息相关,分析教育哲学的涨落与分析哲学的兴衰势呈呼应。这种“血缘”关系是影响分析教育哲学涨落的一个重要因素。分析教育哲学之潮在教育哲学领域涌过之后,并非遗产全无。分析教育哲学或改头换面,或新瓶旧酒,对现代教育哲学产生潜移默化的影响。     

对学情分析的反思

随着课程改革的深入,学生的“学”逐渐受到应有的重视,学情分析也已然成为教案设计的重要环节。学情分析具体包括对学生学习态度分析、学生已有知识经验分析、学生学习能力分析和学生学习风格分析等内容。在进行学情分析时,教师应当能够明辨学情,并随着学生的变化而不断更新,将学情分析落到实处。     

学情分析:有效教学设计的前提

一个课时知识点教学的有效性离不开"教材分析"、"学情分析"与"教学法分析"及其合理地整合,教学设计的准备工作就在于这"三项分析"."学情分析"与"教材分析"是"教学法分析"的基础,"教学法分析"又反作用于"教材分析"与"学情分析";"教材分析"乃是有效数学教学设计的基础,"学情分析"是实现数学教学目标的关键,构成了有效数学教学设计的前提.     

简论财务报表分析

财务报表分析是企业决策的重要依据之一。财务报表分析可分为外部分析、内部分析、专题分析三种,而外部分析主要是指企业偿债能力指标分析、企业资产管理比率指标分析、企业盈利能力指标分析。通过分析发现资产负债率、资产总额净利率和成本费用利润率存在不足,应补充经营活动净现金流量与营业利润比率、投资活动净现金流量与投资收益比率两个分析指标,使企业能够更全面地进行盈利能力评价和分析,进而完善财务指标分析体系,更好地为管理者决策提供有用信息。

漏洞百出的教育

Many college freshmen arrive woefully unprepared to do college work, and as disadvantaged populations continue to grow, the share of the American work force that has made it through college is expected to plummet. Many experts blame that educational failure not just on high schools but also on colleges. School & College, a special report by The Chronicle, looks at efforts to fix the system. What reforms would better prepare students for college? What should schools and colleges be doing differently? How should state and federal officials help?     

只要努力,不要后悔

There are numbers of crossroads on our long and unpredictable life journey where we totally have no idea about which direction to choose. No matter what our decision is, we should not turn back, but face the music and go ahead instead. I am this kind of girl who always does try without regretting, one example is how I dealt with my love.     

浅谈移民问题

Migration occurs behind a variety of reasons and has a great effect on the whole world. People may migrate in order to improve their economic situation, or in order to escape civil strife, persecution, and environmental disasters. The impact of migration is complex, bringing both benefits anddisadvantages. This paper briefly talks about the causes of migration, the allocation of benefits, and the ways in which individual countries and the international community deal with this important subject.     

Sister Carrie, an Adherent of Desires

Sister Carrie is one of the most controversial characters in American literature.Thought as a "fallen woman" firstly,she was defined as a "new woman" by some critics later. However, by digging into the motivaton behind the whole process of Carrie's "success", the relationship between Carrie and her creator (the author), the social conditions of then American, it can be found that Carrie has never been free-standing on her thought and she has never found her real-sdf even after becoming a famous actress. In a society dominated by mass consumerism Carrie is only an adherent of her own desires. She also is a representative of all those country girls flooded into cities, a symbol and a sacrifice of the urbanization of America in a time countryside was overcome by cities.

胡主席在印度,我却在中国

Today, Sunday morning, I sit thinking and typing at my computer. My thoughts are in my homeland, India and my body is in China. The body is here and mind there for a good reason. Mr. Hu is president and I am resident and both are in each other's countries (what a difference the absence of one small letter makes!). Mr. Hu will return in a few days and I will stay on longer.
