imatfaal Posted July 21, 2014 Share Posted July 21, 2014 ! Moderator Note moved to speculations. and in future please ask a question, or raise a point for debate rather than cut and paste. Link to comment Share on other sites More sharing options...

xiaojun Posted July 21, 2014 Author Share Posted July 21, 2014 Here on the Doppler wavelength is obtained two results，One (8) type，Another (14)，Whether it is a right.？ Link to comment Share on other sites More sharing options...
swansont Posted July 21, 2014 Share Posted July 21, 2014 You lose me at equation (3), when you have [math]k\lambda = k\lambda(ch^2 \theta - sh^2\theta)[/math] No explanation of these additional terms. And then equations 4 and 5 pop up from nowhere. Link to comment Share on other sites More sharing options...

Only the expression of wave vector and the wavelength of the meeting (4) (5) of two type, the wave vector and the wavelength of the expressions can satisfy (3).

That means nothing to me. What are c, h, s and theta? Link to comment Share on other sites More sharing options...

swansont Posted July 23, 2014 Share Posted July 23, 2014 Now explain why they suddenly appear in the equations. Link to comment Share on other sites More sharing options...
xiaojun Posted July 23, 2014 Author Share Posted July 23, 2014 Now explain why they suddenly appear in the equations. Because the required k'λ'=kλ, and (coshθ)^2 - (sinhθ)^2=1 Link to comment Share on other sites More sharing options...
swansont Posted July 23, 2014 Share Posted July 23, 2014 Because the required k'λ'=kλ, and (coshθ)^2 - (sinhθ)^2=1 What is the basis for requiring (coshθ)^2 - (sinhθ)^2=1 ? Where does the equation come from? θ just appears in your equation without prior mention or definition. Link to comment Share on other sites More sharing options...

swansont Posted July 23, 2014 Share Posted July 23, 2014 I had not gotten that far. Usually you put equations in order that they are used, i.e. something defined in equation 7 should not be used in equation 3. Also, column formatting means you read top-to-bottom of the left column. ___ Ignoring, for the moment, the source of these equations, what you have done here is math. If you have found an inconsistency, then it means there is a math error. Link to comment Share on other sites More sharing options...

swansont Posted July 23, 2014 Share Posted July 23, 2014 Somewhere before equation 14, where you notice an inconsistency, you have made a math error of some sort. Algebra or an invalid constraint are two likely candidates. Link to comment Share on other sites More sharing options...

swansont Posted July 23, 2014 Share Posted July 23, 2014 I'm not really interested in finding your error. What I do know is that all you have done here is math, so if there is a problem, it is a math manipulation problem. Link to comment Share on other sites More sharing options...

All the conclusions I are derived by mathematics, a theoretical and experimental foundation strong, eager to the moderator to find the existing problems in the mathematical derivation.
