What does domain mean and what does domain mean

A field, a space occupied and defended by animals, contains all the resources needed by the occupier, such as food, nesting and mates. Possession of the territory can be an individual, a couple, a family, or a group of animals.

Its main features are:

1) is a fixed space or area whose size can be adjusted over time and ecological conditions;

2) is an area that is actively defended and defended by the occupier of the territory;

3) The exploitation of the domain is exclusive, i.e. it is monopolized by one or more individuals. Different areas generally do not overlap, and if the overlap is also small and temporary, the overlapping areas can be used jointly by the occupants of the two domains, but at different times. Domains are ubiquitous in vertebrates, including bony fishes, frogs, salamanders, lizards, crocodiles, birds, and mammals.

In rodents and primates, the population domain is more common. Many invertebrates also have domains, such as dragonflies, crickets, flies, butterflies and various hymenopteran insects in the class Insecta, as well as crickets, fiddler crabs, scallops, turtles and octopuses in telopods and molluscs in the class Crustacea.

Domain (pinyin: yù) is a Chinese character (commonly used character) in the general standard of Chinese. The ancient writing of the domain is "or" (yù)", the left is like a region, and the right is the "ge" used for guarding.

It is about to divide the "domain" next to the "soil" of the seal text. "Domain" is a differentiation of "or", which originally refers to a place within a certain boundary.

Domain, territorial river basin. Simply put, the scope of a certain power. It can be extended to other aspects. For example, the field of science and technology refers to the entire range of technologies.

1.An area in which a country exercises sovereignty.

2.Scope of academic thought or social activity: Thought. Life. In the natural sciences, mathematics is the most important foundation.

The field is the scope, how big, it means!

1. First of all, the domain is a concept of a set, that is, the field is a set of infinite values, and the properties of the set are all satisfied, for example: x0 (x0-δ, x0+δ).

2. Secondly, the field must determine the set centered on a certain variable, because the field is developed from calculus, therefore, the main research object of the field is not like the set, the set is the study of the elements and their composition in the set, and the field studies the tiny variable δx in the direction of calculus; The field and the set belong to the object of study;

3. Again, for a unary function of the form y=f(x), under the tiny variable δx of x, what is the trend of y, i.e., δy, which is studied by calculus, but in order to examine δx, it must be placed in a certain set, which belongs to the domain of x, but is a tiny set centered on x0, i.e.,

x0-δ, x0+δ) can also be said to be a tiny collection domain with x0 as the center and δ>0 as the radius, this is the field!

4. For binary functions and multivariate functions, the concept of domain is similar!

A neighborhood is a basic topology on a set. He has research works on neighborhood axioms (neighborhood axioms are the basic concepts of modern mathematical topology), open and closed neighborhoods, and decentered neighborhoods.

Neighborhood axioms. Elementary definition.

The neighborhood is a special interval, with point A as the center point, any open interval is called the neighborhood of point a, denoted as u(a).

δ neighborhood of point a: Let δ be a positive number, then the open interval (a-δ, a+δ) is called the δ neighborhood of point a, denoted as, point a is called the center of this neighborhood, and δ is called the radius of this neighborhood.

Since it is equivalent to, therefore, represents the whole of all points x that are less than δ at a distance from point a.

The decentering δ neighborhood of point A: Sometimes the neighborhoods used need to remove the center of the neighborhood, and after the δ neighbor of point A removes the center A, it is called the centering δ neighborhood of point A, which is recorded as (the expression is marked with a small 0 on u), that is, it is represented here. Sometimes the open interval (a - a) is called the left-δ neighborhood of a, and the open interval (a, a + is called the right-δ neighborhood of a. [1]

<> field of work refers to the place where you work and all the categories related to your work and professional direction of your work.

Adopting a comprehensive classification approach, the fields of work are usually divided into nine categories, namely, social work for children, social work for adolescents, social work for the elderly, social work for women, social work for the disabled, social work for families, social work in schools, social work in medical care and social work in correctional work.

It is aimed at the needs of specific occupational fields in the society, and cultivates strong professional ability and professional quality.

A degree category (degree type) set up for high-level applied professionals who can creatively engage in practical work, and the specific category is a professional degree.

Category. Professional degrees are at the same level as the corresponding academic degrees and academic degrees, and the training specifications have their own emphasis.

The professional degree has a relatively independent education model, which is characterized by the integration of industry and education, and is a high degree of unity between vocational and academic. It is at the same level as the academic degree, and the training specifications have their own emphasis. Together, professional and academic degrees make up modern higher education.

The two indispensable components of the degree system are both interrelated and distinct.
