This reflects the explanatory power of which elements in the theoretical model of public safety triangle.

This is a multiple-choice question. The topic of A risk, B disaster-causing factors, C induced correlation and D vulnerability of disaster-bearing body is selected as D.

At present, the public security scientific community has put forward a triangular model of public security system, which consists of three aspects: emergencies, disaster carriers and emergency management, and disaster elements are distributed in it.

There are many types of disaster elements, such as the leakage of dangerous chemicals, and the type of disaster element is substance; When an earthquake occurs, the type of disaster element is energy; Rumors leading to social panic and mass incidents, the form of disaster elements is information.

In addition to the triangular model, the time index is also important when people feel that their area is safe. For example, a fire scene or emergency rescue, people will have an expectation of the time when rescuers arrive at the scene. This time expectation is closely related to the time process in emergency management. For example, emergencies have a process of occurrence, development, mutation and decline, reaching a certain critical interval, which may cause the greatest damage to the disaster-bearing carrier.
