A general explanation of the concept.

A method of expanding the extension of a concept by reducing its connotation. If the connotation of "including and explaining specialized words" is reduced to the concept of "specialized dictionary", the extension of the concept will be expanded accordingly and the transition will be made to a "dictionary" of generic concepts.

Word decomposition Explanation of concepts The essence of the object formed in the mind is a form of thinking that reflects the nature of the object. The common essential characteristics of the perceived things are abstracted into a group of traces and summarized violently, and they become concepts, and concepts have connotations and extensions, and change with the development of the subjective and objective worlds, and explain in detail the forms of thinking that reflect the essential attributes of objects. People generalized explanations inductively, generally.

To summarize the common characteristics of things and to describe them concisely, to summarize them in one sentence is to summarize and summarize the knowledge of nature and society. What is Knowledge?, to summarize or summarize, it is summed up in exactly three words: as an induction or a general generalization.

Acceleration is a physical quantity that describes how fast or slow an object's first change in velocity is, and it is defined as the ratio of the change of velocity to the time it takes for the change to occur

Therefore, the answer is: how fast the velocity of the object changes; the ratio of the change in velocity to the time it takes for that change to occur; ratio method; Velocity.

Answer] :(1) The methods defined are:

Definition of genus plus species difference.

It is defined by revealing adjacent genera and species differences, which is referred to as the "genus plus species difference definition". The formula is: defined concept = species difference + adjacent genera. Species difference is the characteristic or essential property of an object reflected by a defined concept that distinguishes it from other species of things contained in the same genus.

Definitions of terms. A word definition is a definition that reveals the meaning expressed by a word, and word definition can be divided into:

a.Definitions of the terms of the description.

It means that when others do not understand the meaning of a word, we have to use a word definition to explain the meaning of the word.

b.Definitions of prescribed terms.

It means more than just the need to state the predetermined meaning of a word. There is also a need to assign meaning to certain words, including imported symbols.

2) Defined rules.

The definition must be proportionate, that is, the extension of the definition term has the same relationship with the extension of the defined term. Violating this rule will result in the following logical error.

a."Definition too broad".

"Definition too broad".'It is specified that the extension of the pure defence-carrying term is greater than the extension of the defined term.

b."Definition too narrow".

"Too narrow" means that the extension of the defined item is less than the extension of the defined item.

Defined items must not directly or indirectly contain defined items.

If the defined term directly or indirectly contains the defined term, the purpose of clarifying the connotation of the defined term cannot be achieved. The following logical error will occur:

a."Repeating the same language".

"Repeating the same language".'It means that the defined item is directly included in the definition item, and the definition item and the defined item are only different in language form.

b.Loop Definition

The circular definition of "Hidden Tomb" means that the definition item indirectly contains the missing definition term.

The definition must be in the form of affirmative statements and positive concepts.

The purpose of defining a concept is to reveal the connotation of the concept and to indicate the specific or essential properties of the object reflected in the defined term. If the definitive text is not in the form of an affirmative statement, or if it is not in the form of a positive concept, the purpose of the definition will not be achieved.

The definition must be clear and precise.

The definition reveals the meaning of the defined item. Indicates the unique or essential properties of the object reflected in the defined term, so it is required that the statement that expresses the definition must be clear and precise.
