In real life, we use a lot of model of this means, such as in the manufacture of die before we will use wood to make a and needs to die as like as two peas model, then the model is tested, modified, until we satisfied with it only make a true mold, this is because the production molds, high hardness of metallic materials compared to more easily, wood processing, wood production model of price of flowers are small, time is very short, there are deviations are easy to modify, even if the deviation is big, need to be abandoned again, lazy mother recommended 10 classic children’s book, the loss is small. For example, in aircraft design, to use the tunnel to simulate the flight environment, in the wind tunnel can be easily on a certain part of the design of aircraft for inspection, the experiment can be the real aircraft components, can also be a component model, without the need for the plane manufacturing after the fly can test design scheme. Even when the plane can fly to the sky, only to aircraft performance is evaluated, not on a particular components were detected, unless the component failure caused the plane crash, the price is heavy, even after the crash to find where is the problem.
The model has several kinds, one kind is given above the first example, the model and the prototype shape is similar, but different sizes or use different materials, aims to study the prototype geometric properties, such as the external surface of the die shape, this model is called geometric model; if a research prototype physical characteristics, and with archetypes like the material model, physical model, such as the example above tunnel, broadly geometric model is a physical model. The physical model is simple and intuitive, easy to use, in practice there are a large number of applications, but a particular physical model application scope extremely narrow, to study a kind of prototype must build a physical model, such as the use of the original in the enlarged sample manufacture method, is to use wood processing raw materials to manufacture a and practical to make a ship parts as large as the model, then the model parameters to prove. On a boat on the sample for another size or structure of the different ship is of no use. In order to make the argumentation of rigorous, different types of ships must be enlarged sample, do not say that for different kinds of things such as ships and cars between them no universal model.
The model has advantages and effects we have known very clearly, brain using model mode has the same advantages, is the first model than the actual action cost is much smaller, based on the analysis of the model can replace part of action – feedback so typical of the quest, and use the model of consumed energy low, can greatly save the animal precious energy resources. Secondly it can before action in nervous tissue to make action plan and Simulation of the movement, the reasonableness and effectiveness of the judgment, the predetermined action possibility and probability of success, to improve the accuracy and correctness of the action. Just like people in the design of the automobile when, to produce various models, measurement and test, and then modify the design, finally to create a prototype, the model has a good overall performance, if not through direct fabrication of prototype model stage, perhaps even assembly is very difficult, let alone run. In some cases may not perform or not necessary for practical action, then we can according to the model of assessment is made, then choose the right strategies, such as in the animal encounters predators when choice may only once, the blind actions resulted in tragedy, then use the model of the possible choices and their consequences for assessment is particularly important.
The model includes a digital model,Anatomical Model. chemical model, physical model, geometrical model, plant model.
The model from the implicit state to state is obvious neurological history big leap, its significance can be generated in the computer and software development history status compared.
