① Why is it wrong to require that the external circuit of a two-segment network be linear when applying Thevenin's theorem

A two-port network is a circuit or device with 2 ports, and the ports are Circuits are connected to internal networks. A port consists of two terminals. When these two terminals meet the port conditions, that is, the same current flows into or out of the same port, as shown below, a simple strictly linear two-port network is formed (excluding independent sources and only linear The circuit is composed of original components), the port conditions have been written below the figure, u1, u2 are the port voltages. Linear two-port network parameters are usually written in matrix form.

The two-port network is represented as v=Ri, where v and i are vectors and R is a matrix.

where r can be determined by the following equation (for the convenience of calculation, we set R1=R2=R3 equal to 1Ω):

It can be seen that the unit of r is ohm (Ω) .

The essence of a strictly linear two-port network in linear space is a two-dimensional plane passing through the origin in four-dimensional space. The four coordinate axes of the four-dimensional space are u1, u2, i1, and i2. Since it is A plane, then we can use the linear combination of a pair of basis vectors to represent a strictly linear two-port network. First, we need to find a set of basis vectors. We arbitrarily take two sets of data in the two-port network (as shown in the figure below), For example, in the picture above, we can make the first set of data u1 equal to 0v and u2 equal to 1v, and then find i1 and i2. For the second set of data, let u1 equal 1v and u2 equal 0v, and then find i1 and i2. In this way, we get two sets of linearly uncorrelated data:

The first group:

The second group

Then select C1 and C2 as The parameters can express this two-dimensional plane:

Or we can use the linear combination method to express it

Or we can use the image space (image) of the matrix to express it:< /p>

② Six-dimensional expansion of Internet marketing Bagua expansion. What is upstream and downstream expansion

1. The basis of word expansion: core words

Core words refer to The word that best represents the company's promotion needs is usually the company's brand or main business name. All word expansion activities are based on core words.

1. Obtain core words according to corporate needs

1) Brand promotion. If the company's promotion needs are brand promotion, then its core words must be brand-related words, such as Tmall, Tmall, Tmall Mall, etc.

2) Main business promotion. If an enterprise obtains orders to promote its own business, the core words are the main products/models/business models, such as iphone7, English training, European travel, etc.

3) Activities/Promotional marketing. If the company's promotion needs at this time are to promote promotional activities, then the core words are the event name, content, price, etc., such as Double Eleven, Peach Blossom Festival, etc.

2. Obtain core words from corporate websites

The most intuitive ones are e-commerce malls such as JD.com. You can find the core words from the product classification of the mall. . In other websites, rich core words can be found through product pages.

2. Basic methods of word expansion

1. According to the search habits of netizens

I believe you will notice in your daily life that netizens are searching When writing, we often use some very "strange" words, such as the pinyin, synonyms, aliases, spoken language, written language, abbreviation, full name, etc. of the core word, which can be expanded into our keywords.

The master has said that the most ideal account status is that every word is set to exact match, and every relevant search word of netizens can match the corresponding keyword. Expanding such words can effectively reduce CPC, thereby saving promotion costs.

Lecture 20: Basic methods of keyword expansion - Picture 1

2. According to the different concerns of netizens

Netizens should If you find a product you want to buy on the Internet, you must have your own concerns. For example, product quality, function, price, reputation, promotions, etc., each netizen pays different attention to it, which also means that these aspects can be used as a direction for word expansion.

The following picture uses six-dimensional expansion words as seed words to expand breadth in eight directions, which explains the basic method of word expansion in more detail. Lecture 20: The basics of keyword expansion Method - Picture 2

3. Expand words upstream and downstream according to the needs of netizens

Start from the essence of netizens’ needs and do in-depth expansion upstream and downstream. Lecture 20: Basic methods of keyword expansion - Picture 3

For example: Dermatology Hospital ← Dermatology ← Scar

Lecture 20: Keyword expansion Basic method - Picture 4 For example: subdivided by scar classification: depressed scars, flat scars,... According to scar location: facial scars, back of hand scars,...

Eichibacterium is here Let’s list the most basic keyword expansion types for an account:

1. Product words (product name, model, for example: iphone7)

2. Price words (XX price , how much is XX)

3. Company/manufacturer words (for example: clothing customization manufacturers, English training institutions)

4. Regional words (for example: Xiamen English training)< br />
5. Word-of-mouth words (for example: which English training company is better)

6. Brand words (for example: JD.com, Suning.com)

No matter what industry it is, these types of words are necessary when setting up an account in the early stage.

In fact, the more keywords, the more relevant, and the more detailed, the better. SEM is endless, and writing is endless.
