Description
Technical field
The utility model belongs to Popular Science Education or teaching field, is specifically related to a kind of three leaves Chaos Pendulum apparatus for demonstrating.
Background technology
The certainty of dynamic system is a mathematical concept, refers to that system state at any one time is determined by original state
It is fixed.Although the initial condition data and the characteristics of motion according to motion can extrapolate the motion state of any future time instance, due to
The measure of initial condition data can not possibly be completely accurate, and error necessarily occurs in the result of prediction, or even unpredictable.That moves can
Predictability is a physical concept.Even a motion is deterministic, also still can be for uncertain, the two not contradiction.
The success of Newtonian mechanics, particularly its success on prophesy Neptune, misunderstand, certainty and can to a certain extent
Predictability is equated, and thinks that regular motion must be predictable.Research after 20 century 70s shows, a large amount of non-thread
Although being to determine property of system in property kinematic system, generally existing extremely sensitive to motion state initial value, seemingly random
Uncertain motion state be chaos phenomenon.
Chaos phenomenon refers to a kind of seemingly irregular compound movement form present in real world.Common trait is former
To follow the ordered movement form of simple physical rule, deviate suddenly under certain conditions expected regular and become unordered
Form.Chaos phenomenon can occur in quite extensive some certainty dynamic systems.Chaos phenomenon is in statistical property
Similar to random process, it is considered to be a kind of intrinsic stochasticity in deterministic system.
In teaching process, usual teacher will draw chaos mechanism on blackboard, try to describe the shape of chaos phenomenon
State, but the not visible property due to chaos in itself, cause the difficulty of object teaching.There is the simple mixed of individual example in modern education activity
Ignorant swinging mechanism, majority is two section mechanisms, and there are many deficiencies in this mechanism the simplest in practical activity, due to structure excessively
Simply so that visitor or learner misunderstand, think that Chaos Pendulum is exactly such simple mechanism, so as to have ignored real life
Chaos swinging mechanism different in work.
