题 目:General theory of reproducible experiment: Apparatus function and reduction to an ideal experiment
内容简介:The author suggests a general theory for consideration of all experiments associated with measurements of reproducible data in one unified scheme. The suggested algorithm does not contain unjustified suppositions and the final function that is extracted from these measurements can be compared with competitive hypotheses that are suggested by a theory for explanation of the object studied. This true function is free from the influence of the apparatus (instrumental) function and in the case (when the "best fit", or the most acceptable hypothesis, is absent) can be presented by a segment of the Fourier series. The discrete set of these decomposition coefficients describes the final function quantitatively and can serve as an intermediate model (IM). This IM coincides with the amplitude-frequency response (AFR) of the object studied and can be used by theoreticians also for comparison of the suggested theory with experimental observations. From this general theory the following important conclusions follow:
1. The Prony's decomposition should be used in detection of the quasi-periodic processes and for quantitative description of reproducible data.
2. The Fourier decomposition should be used for quantitative description of observable data corresponding to an ideal experiment. The transition from the initial Prony's decomposition to the conventional Fourier transform implies also the elimination of the apparatus function that plays an important role in reproducible data processing.
3. New theory will be helpful for creation of the Unified Metrological Standard (UMS) that should be used in comparison of similar data obtained for the same object studied but in different laboratories with the usage of different equipment.
4. Many cases when the conventional theory confirmed the experimental data obtained on equipment where the apparatus function was not taken into account should be remeasured and some of the competitive theoretical hypothesis can be reconsidered also.
5. New theory after the optimization of its basic algorithm can automatize the whole procedure of measurements tuned for collection and further analysis of reproducible data.
Some examples based on available data received from different laboratories confirm the basic elements of this new theory.
