Method for determining stability of reservoir bank slope based on reservoir water level and displacement

The invention belongs to the technical field of slope stability diction and slope disaster monitoring and precaution, and particularly relates to a method for detecting a displacement and reservoir water level coupling power prediction parameter and stability of a reservoir type slope geological disaster. According to the basic principle of damage mechanics, a skid resistance force and sliding force loading power parameter on the slope sliding face and a slope displacement response parameter are organically coupled, and the new method for determining the stability of the reservoir type slope is disclosed according to the organic coupling. The method can effectively overcome erroneous judgment or misjudgment caused by errors of slope physical and mechanics parameters, boundary conditions and the like in a traditional ultimate equilibrium mechanical evaluation method and meanwhile solves the problems that a traditional displacement time sequence prediction method cannot describe a slope power action mechanism in a quantitative mode and cannot stably unify instability criterion. The clear criterion is adopted to specifically express the stability state of the slope in different stages of the reservoir, and effective basis is provided for slope prediction forecast and precaution treatment.

Earphone hearing adjusting method and earphone

The invention provides an earphone hearing adjusting method and an earphone. According to the earphone hearing adjusting method, an actual acoustic frequency response parameter of a loudspeaker is tested when an earphone is worn at ears of a person normally; the actual acoustic frequency response parameter and a preset standard parameter are compared to obtain an actual frequency response difference value of the actual acoustic frequency response parameter and a preset standard parameter; whether the actual frequency response difference value is larger than a preset difference value is determined; if so, a loudspeaker is adjusted to send a sound signal to reduced the actual frequency response difference value, so that the actual frequency response difference value is less than the preset difference value. Therefore, the actual frequency response difference value can be controlled within the preset difference value when the earphone is worn by ears of different users, so that the hearing of earphone wearing by different users is identical with that in a standard wearing mode. Besides, the loudspeaker can be adjusted to send the sound signal to avoid the influence on the hearing experience due to sound leakage. No rubber cover needs to be worn in auditory meatus, so that an auditory meatus fatigue feeling caused by filling the auditory meatus by the earphone can be avoided.
