大学物理实验报告-弗兰克赫兹实验  大学物理试验 2009-02-26 18:59:30 阅读17868 评论14 字号:大中小 订阅  大学物理实验报告  实验题目:弗兰克赫兹实验  实验器材:F-H实验管、恒温加热电炉、F-H实验装置、示波器。  实验内容:  1.熟悉实验装置,掌握实验条件。  该实验装置由F-H管、恒温加热电炉及F-H实验装置构成,其装置结构如下图所示:  F-V管中有足够的液态汞,保证在使用温度范围内管内汞蒸气总处于饱和状态。一般温度在100 ºC至250 ºC。并且由于Hg对温度的灵敏度高,所以温度要调好,不能让它变化太大。灯丝电压控制着阴极K发射电子的密度和能量分布,其变化直接影响曲线的形状和每个峰的位置,是一个关键的条件。  2.测量Hg的第一激发电位。  1)起动恒温控制器,加热地F-H管,使炉温稳定在157 ºC,并选择合适的灯丝电压,VG1K=5V,VG2p=5V,Vf=3V。  2)改变VG2k的值,并记录下对应的Ip值上(每隔2V记录一个数据)。  3)作数据处理,作出对应的Ip-VG2k图,并求出Hg的第一激发电位(用逐差法)。  3.测Ar原子的第一激发电位。  1)调节好相关的数据:Vp=36V,VG1=62V,VG2k=0~100V,Vf=64V;  2)将相关档位调到自由档位,在示波器上观看得到的Ip-VG2k图,是否符合实验要求(有六个以上的波峰)。再将相关档位调到手动档位。  3)手动改变VG2k的值,并记录下对应的Ip值上(每隔05V记录一个数据)。  4)作数据处理,作出对应的Ip-VG2k图,并求出Hg的第一激发电位(用逐差法)。  4.得出结论。  原始数据:   Vf=3V VG1K=5V VG2p=5V T=157ºC  求汞原子的第一激发电位的数据表

Abstract: Physics is the basis of experimental subjects, physics experiments enable students to obtain specific physical facts, a clear This understanding the students understand the concepts and laws of the ability of students to observe and experiment plays an irreplaceable Therefore, the experimental teaching in physics teaching, with its many unique features, which restricts the level of teaching and teaching In recent years, with the promotion of quality education, inquiry teaching in science teaching is not only widely used, and has been used in experimental People in pursuit of inquiry, however, when only the form without obtaining the gods, in the past as an experimental verification of the main teaching experiment been left As everyone knows, confirmatory experiment teaching method is able to work for many predecessors in favor of education, teaching courses in middle school experiment occupies such a large proportion of the superiority of their own can not be With the changes in the educational system, as well as in-depth understanding of education, validation of experimental teaching in the cold is But blind acceptance of the new teaching method is also With the innovative spirit of the advantages of absorbing new knowledge has been used to verify experiment teaching to generate new vitality, a teaching This validation experiment on the reform of teaching ideas and explore the integration of teaching Key words: confirmatory test; inquiry; pedagogy; improvement; integration

我觉得大学(程度)物理实验 college (level) physics experiment 其实和一楼水过留沙的差不多, 二楼zclyyh意思差的就远了 physical test 更像是体能测验这个不错
