声光衍射中布拉格衍射和喇曼奈斯衍射的区别?

可以改造,很简单.
可以直接把声光开关去掉,接上普通开关即可.

声光衍射中当超声波频率较低和较高时会影响波的波长,在同一介质中传播时,频率高时波长短,频率低时波长长,这会使衍射亮条纹的宽度不同,当波长长时即频率低时,亮条纹较宽,频率高时,亮条纹较窄.

这个问题你悬200追100我帮你做

所有物理学变化(或称物理学现象),其内在本质是能量的转移或转化,这就是力热声光电等各分类的联系.
如楼主所举的例子中,实际上是电能转化为内能(俗称热能),然后一部份内能转化为光能,如果爆炸了,也是内能转化为动能(机械能).
所有的例子就是能量的转化或转移.

Pt-TiO2 composite electrode ultrasonic Photocatalytic Properties of Organic Compounds
Abstract
Acousto-optic catalytic reaction is photocatalytic traditional applications in wastewater treatment developed.Pt contains the TiO2 nanotube at a fixed carrier,the active substance is not easy to fall off,to a certain extent can be reused.At the same time,ultrasound can also degrade organic pollutants.This study used the first anodic oxidation of titanium at the surface of TiO2 nanotube arrays obtained through ultrasound-assisted Preparation of Pt-TiO2 nanotube arrays.Secondly,the use of Pt-TiO2 nano-array composite photocatalytic degradation,ultrasonic degradation,ultrasonic and photocatalytic degradation of organic compounds (methylene blue).Comparison of photocatalytic degradation,ultrasonic degradation and ultrasonic properties of photocatalytic degradation of organic matter and ultrasonic frequencies,power,time Sonophotocatalytic containing Pt time to Pt-TiO2 nanotube array degradation process of organic pollutants.Come to the conclusion:the introduction of ultrasound to enhance the advancement of the Pt-TiO2 nano-array composite photocatalytic degradation of organic matter degradation rate; degradation rate is affected by reaction time,ultrasonic power,frequency; increase in the time set Pt can enhance the degradation of organic matter rate.

论文方面的可以在GOOGLE上去翻译,上面通常挺准确的.

闪电,雷鸣,电灯,

1.峰值功率就是一个脉冲的功率,等于一个脉冲的能量除以脉宽．因为声光调Q激光器是脉冲运转的,它只能定义”平均功率”,不能定义”功率”,平均功率实际上是调Q激光器长时间运转的功率,等于一个脉冲的能量乘以频率．
2.所以峰值功率乘以脉宽等于一个脉冲的能量,如果你知道发光频率的话,乘以频率就是平均功率．

触觉痛觉是神经的感受,其实与物理没多大关系,至于嗅觉是分子本身的性质,没什么可以研究的
