example 1

[0039] Example 1. Prove the correctness of the law of buoyancy.

[0040] Archimedes' law of buoyancy: buoyancy F R Equal to the weight of the liquid displaced by the floating body (the product of the volume of the liquid displaced by the floating body, the density of the liquid, and the acceleration of gravity). That is, F R =λVg.

[0041] Proof: From the point of view of traditional theory, the law of buoyancy only involves the relationship between action force and reaction force. From the perspective of mechanics, the law of buoyancy involves multiple concepts and their interrelationships. These concepts include action, action, actual action, actual force, imaginary action, imaginary force, resultant force, resistance, deformation, liquid properties (empty or solid). According to functional theory, there are the following relationship rules between these concepts:

[0042] The amount of action A is equal to the force F multiplied by the action time t, that is, A=Ft; whe...

example 2

[0056] Example 2. Prove the scientific nature of the traditional stress-strain theory.

[0057] Proof: ⅰ. Understanding its unscientific nature from the traditional stress-strain relationship itself:

[0058] The basic content of the traditional stress-strain relationship theory: in a unidirectional stress state, the stress-strain relationship of an ideal elastic-plastic material satisfies Hooke's law, that is

[0059] σ=Eε.

[0060] In the formula, σ represents the stress; ε represents the strain; E is the modulus of elasticity. This relational expression does not satisfy the law revealed by Newton's law, the dimensions on both sides of the equation are not unified, the dimensionless parameter E becomes a dimensioned parameter, and the objective meaning of the parameter is lost.

[0061] According to the unified quantitative theory of opposites and opposites in kinetics, the relationship between stress and strain should be

[0062] ϵ = ...

example 3

[0075] Example 3. Demonstrate the correctness of the labor-saving principle of lever and pulley block.

[0076] ⑴. Leverage principle: the working method and principle of using a small force to lift a large weight (a small driving force overcomes a large resistance) with the help of a lever. The lever principle of mechanics refers to the condition of lever balance. The condition of lever balance means that in the leverage system, the product of the driving force received by the lever at the driving end and the driving force arm is equal to the product of the resistance received by the lever at the hindering end and the resistance arm, that is, force × force arm = resistance × resistance arm, whose mathematical expression is r 1 F=r 2 R or Such as figure 1 shown. Mechanics believes that the lever can make the force smaller.

[0077] ⑵. Pulley block labor-saving principle: with the help of pulley block, use a small force to lift a large weight (use a small driving force t...

Abstract

The invention relates to a discrimination method for demonstrating the correctness of scientific principles and laws, and belongs to the field of basic research of basic scientific theories and application. The method irons out a defect that there is no method for the evaluation of the scientificity of scientific principles and laws in the prior art, and the method mainly comprises the following steps: A, demonstrating whether opposite unity quantitative theories of principles or laws and effects are consistent or not; B, carrying out an experiment or example demonstration; C, carrying out quantitative comparison and determination of the correctness of principles or laws; D, demonstrating the correctness of the principles or laws according to other effect theories. The beneficial effects of the invention are that the method is suitable for the demonstration of the correctness of various types of principles and laws in the conventional natural science basic theories; the demonstration purpose not just aims at determining the correctness of theories, principles and formulas, but also aims at further knowing the natural rule and mastering and flexibly using the objective laws.

Description

technical field [0001] The invention relates to a judging method for demonstrating the correctness of scientific principles and laws, which belongs to the field of basic scientific theory and applied basic research. Background technique [0002] The degree of perfection of basic science is the key to determining the scientificity, accuracy and reliability of people's understanding of problems and problem solving (such as detection, analysis, calculation). [0003] Determined by the superstition of principles and laws, people still stay at the level of mechanics theory and methods in terms of basic scientific theories and methods, and have not been greatly developed for a long time. In fact, some principles and laws in traditional scientific theories have their own errors, and the understanding, formulas and methods given by such principles and laws are often flawed or even wrong. Since the basic laws and methods of mechanics cannot be directly used to solve problems in elec...
