By using the graphical analysis of Elliott wave theory, Analyzing the spatial and temporal variation of seismicity before large earthquakes, the earthquake sequences are divided into 2 types, the progressive type and the flash type. According to the 12 bull market wave model of relevant Elliott market analysis theory. The earthquake regularity of the earthquake sequence is classified into 3 categories (12 small classes): triangle, trapezoid and rectangle. Based on the model and law of earthquake occurrence, the equal area determination method is put forward in forecast of earthquake magnitude. At the same time, the empirical method is given to predict the spatial range of earthquake sequence and the prediction of large earthquake occurrence time. At the same time, the empirical determination method is given to predict the spatial range of earthquake sequence and the occurrence time of large earthquake. The conclusion is that there are not only differences between subjects, but also a strong blend. Elliott wave theory showed a high applicability in the analysis of seismic sequence structure, not only make clear graphical seismogenic process of large earthquakes and put forward the theory of the earthquake sequence trigger mode, the law of earthquake prediction and the earthquake magnitude prediction, this will effectively improve the probability level of earthquake tendency prediction in the future.展开更多

Because of this intermediate position, the collapse process cannot be examined with the formalism of the quantum mechanics (QM), neither with that of classical mechanics. This fact makes some physicists propose interpretations of QM, which avoid this postulate. However, the common procedure used in that is making assumptions incompatible with the QM formalism. The present work discusses the most popular interpretations. It is shown that because of such assumptions those interpretations fail, <em>i.e.</em> predict for some experiments results which differ from the QM predictions. Despite that, special attention is called to a proposal of S. Gao, the only one which addresses and tries to solve an obvious and major contradiction. A couple of theorems are proved for showing that the collapse postulate is necessary in the QM. Although non-explainable with the quantum formalism, this postulate cannot be denied, otherwise one comes to conclusions which disagree with the QM. It is also proved here that the idea of “collapse at a distance” is problematic especially in relativistic cases, and is a misunderstanding. Namely, in an entanglement of two quantum systems, assuming that the measurement of one of the systems (accompanied by collapse of that system on one of its states) collapses the other systems, too without the second system being measured, which leads to a contradiction.展开更多
