What is the difference between a connection and a link? The difference between a connection and a co

The three concepts of "connection", "connection" and "connection" in the textbook "Geometry" in junior high school are often confused by students because of their similar pronunciations

Joining and connecting both refers to connecting two points with a line, but the line that "joins" the two points can be a line segment or a curve, while the line that "connects" the two points can only be a line segment Obviously, there are countless ways to connect two points, but there is only one way to connect two points, specifically to connect the line segments As shown in Figure 1, all the lines between points A and B are lines connecting A and B, and only the line segment AB is the line connecting A and B It can be seen that connecting two points is a special case of connecting two points, and in the line connecting two points, The line segment is the shortest

Connection is different from connection and connection, connection is to use a point to connect two lines, the key is to "connect", and connection, connection is to use a line to connect two points, the key is to "connect" At the same time, the "connection" of the connection is not a simple connection, but to achieve a smooth transition between lines There are two main types of connections One is the connection between the line segment and the arc, which must meet two conditions; The line where the line segment is located is tangent to the circle where the arc is located (as shown in Figure 2) The line segment and the arc must be on both sides of the straight line where the center of the circle and the tangent point (i.e., the connection point) are located; The other is the connection between the arc and the arc, and two conditions must also be met: the circle where the arc is located must be tangent The two arcs must be on both sides of the concentric line In this case, it is divided into internal connection (the circle where the arc is inscribed, as shown in Figure 3) and the outer connection (the circle where the arc is located is tangent in the circle, as shown in Figure 4) It can be seen that the line segment and the arc, the arc and the arc are tangent at the junction.

Joining and connecting: both refer to connecting two points with a line, but the line that "joins" two points can be a line segment or a curve, while the line that "connects" two points can only be a line segment Obviously, there are countless ways to connect two points, but there is only one way to connect two points, specifically to connect them into a line segment

Connection is different from connection and connection, connection is to use a point to connect two lines, the key is to "connect", and connection, connection is to use a line to connect two points, the key is to "connect" At the same time, the "connection" of the connection is not a simple connection, but to achieve a smooth transition between lines There are two main types of connections One is the connection between the line segment and the arc, which must meet two conditions; The line where the line segment is located is tangent to the circle where the arc is located The line segment and the arc must be on both sides of the line where the center of the circle and the tangent point (i.e., the connection point) are located; The other is the connection between the arc and the arc, which must also meet two conditions: the circle where the arc is located must be tangent The two arcs must be on both sides of the concentric line In this case, it is divided into inner connection (the circle where the arc is inscribed) and outer connection (the circle where the arc is intangent) It can be seen that the line segment and the arc, and the arc and the arc are tangent at the junction

Generally, it is used to connect points A and B.

I only heard from the teacher that there was a problem with the connection. Blame me for not paying attention to the class. I don't know why, hehe.

<>1. Connecting and connecting both refer to connecting two points with a line, but the line that "connects" two points can be a line segment or a curve, while the line that "connects" two points can only be a line segment. Obviously, there are countless ways to connect two points, but there is only one way to connect two points, specifically to connect them into a line segment;

2. Connecting two points is a special case of connecting two points. Also, among the lines that connect two points, the line segment is the shortest. The difference between connection is that connection is to connect two lines with a point, and the key is to "connect", while connection is to connect two points with a line, and the key is to "connect";

3. The "connection" of the connection is not a simple connection, but to achieve a smooth transition between lines. There are two main types of connections, one is the connection between the line segment and the arc, which must meet two conditions, that is, the line where the line segment is located is tangent to the circle where the arc is located, and the line segment and the arc must be on both sides of the straight line where the center of the circle and the tangent point are located; The other is the connection between the arc and the arc, which must also meet two conditions, that is, the circle in which the arc is located must be tangent and the two arcs must be on both sides of the concentric line. In this case, it is divided into inner connection and outer connection, and it can be seen that the line segment is tangent to the arc, and the arc and the arc are tangent at the connection.

1. Different usage:

Connection: Mainly used to refer to the connection of inanimate objects (physically), such as the connection between points in mathematics.

Connection: Mainly used to refer to a nihilistic or mental connection, such as a connected neuron.

Connection: It has a similar meaning to connection, but it is mainly used to refer to the connection of inanimate objects, such as Jinzhou, which is a strategic point connecting Northeast China and North China.

Connection: Generally refers to the connection of two things of the same nature or appearance, such as the connection of parts and the connection of the Internet.

2. The scope of the definition is different:

Connection: It includes the meaning of connection, connection.

Connection: It covers the meaning of contact, connection, union, unity, and bonding.

Connection: It covers the meaning of connection, association, friendship, etc.

Connection: It includes the meaning of jointing, dynamic and static connection, etc.

First, the key points are different.

1. Connection is to connect two wires with a point, and the key is to "connect". At the same time, the "connection" of the connection is not a simple connection, but to achieve a smooth transition between lines.

2. Connection is to connect two points with a line, and the key is to "connect".

Second, the form is different.

1. Connection refers to the process of connecting two separate profiles or parts into one complex part or component with fasteners such as screws, bolts and rivets.

2. Connection is a technology that uses different ways to connect mechanical parts into one.

The difference between a connection and a join is:

Connection: refers to the process of joining two separate profiles or parts into one complex part or component with fasteners such as screws, bolts, and rivets. Commonly used mechanical fasteners mainly include bolts, screws and rivets.

Connection: The technology of connecting mechanical parts in different ways. The machine is composed of many parts, which need to be connected to realize the function of the machine, so the connection is an important part of the machine.

Those who are coerced will surrender to Pei Songzhi.

Quoted from the Three Kingdoms Wei Wenqin's "Book with Guo Huai": "Servants are connected to the Great Division, far from the same trend, and they want to carve up China, and they are unwilling to take it as their own."

Tang Li Shangyin. Yang Xianggong for Zhang Zhou": "Compared with the sons of Wang Xie, there is a weight of sincerity; Friends and friends in Ji Lu, always connected. The right join is the right weight and the left light, the right table shows all the rows, and the left table shows the lines that meet the conditions.

The uproar used is different:

Connection: Generally refers to the connection of inanimate objects between objects, which means that two objects are connected and connected, because the connection can only be an object (it is basically impossible for living beings such as humans and animals to be connected together).

Connection: refers to a kind of nihilistic spiritual connection, which has the meaning of union and unity.

Connection: The meaning is similar to that of connection, but it mostly refers to the connection of living beings or the meaning of how many metaphors are connected together and combined together, because human beings and animals and other living beings can generally be represented by combination.

Connection: Generally refers to the connection of two things of the same nature or appearance, which has the meaning of interconnection and connection.

The difference between connection and connection is:1The scope of the definition is different, and the connection includes the meaning of connection, unity, union, etc., and the connection only includes the meaning of connection, connection.

2.Usage, a connection refers to a spiritual connection, and a connection is a connection between objects.

In the Dictionary of Modern Chinese

Connection, which means what is combined with what, emphasizes that there is an intermediate substance that binds two things together, such as flesh and blood that bind the two of us together. And the connection means that things are connected to each other, what is connected, emphasizing that things are connected to each other at the beginning and end, and there are overlapping parts, such as:

The two wires are connected by the wire master and are now ready to be energized.

Further reading. When using "join" and "connect", be careful not to write "join" or "link", because these two words are heteromorphic words, and the "first batch of heteromorphic word collation table" recommends the use of "connection" and "connection", and only this way of writing is recognized in the teaching book.
