What is the difference between stability and metastability ?

This seems to be a problem in economics.

Mesostability refers to a system that is far from equilibrium but can maintain relative stability through the exchange of matter and energy with the outside world, which is called a system with a dissipative structure in systems science. Although such a system can be stabilized by self-organization, its stability can easily be destroyed by small external disturbances.

However, after the stability of the system is destroyed, it may swim within a certain range and enter a stable and mesostable state alternately, and it can be considered that the system is stable within a certain range from a macroscopic perspective, that is, it has regional stability. However, sometimes the system may change dramatically after it fails, or even cause the system to collapse. After the collapse of the system, it is possible to return to a mesostable state through deep structural adjustment, or it may die out.

Generally speaking, the greater the inertia of a system, the less likely it is to collapse. The virtual economic system is a metastable system, which must rely on the exchange of funds with the outside world to maintain relative stability. There are many reasons for its metastability, but the most fundamental reason is the inherent instability of virtual capital.

The meaning of stability is available in the encyclopedia, welcome to refer to it.

This is the difference between the stability of colloids and solutions of the two professional terms, the solution has stability, and the colloid has metastability, these two concepts actually have nothing to do with each other, the stability of the solution refers to the solution will not produce precipitation in various physical situations, and the metastable colloid, in some specific physical conditions will produce precipitation (the precipitate is the composition of the colloid).

The introduction of the term metastability refers to the system that is far from equilibrium but can maintain relative stability through the exchange of matter and energy with the outside world, which is called a system with a dissipative structure in systems science.

Although this kind of system can be stabilized by self-organization, its stability is easily destroyed by small disturbances from the outside world. The introduction of macroscopic refers to the system that is far from the equilibrium state, but can maintain a relatively stable system through the exchange of matter and energy with the outside world, which is called a system with a dissipative structure in system science, although this kind of system can achieve stability through self-organization, but its stability is easily destroyed by small disturbances in the outside world.

Colloidal metastability:

The stability of colloids is between that of a solution and a turbidityThe collection and sorting of the education network can exist stably under certain conditions, which belongs to the mesostable system.

There are two reasons why colloids are metastable: reason 1 colloidal particles can be charged by adsorption, and the same colloidal particles have the same charge, and the same kind of charges will repel each other (to make the colloids sink together, it is necessary to overcome the repulsive force and eliminate the charge carried by the colloids).

Reason 2: Colloidal particles are constantly doing Brownian motion, and when they act on the same force of gravity, they form a state of sedimentation equilibrium.

The introduction of the macro refers to the fact that the system is far from the equilibrium state, butHowever, a system that can maintain relative stability through the exchange of matter and energy with the outside world is called a system with a dissipative structure in systems science, and although this kind of system can achieve stability through self-organization and prosperity, its stability is very fingery and easy to be destroyed by small disturbances from the outside world.

Economically, too, the state can be stuffyUnderstand:

After the stability of the system is destroyed, it may swim in a certain range, alternately enter a stable and mesostable state, from a macroscopic point of view, it can be considered that the system is stable within a certain range, that is, it has regional stability, but sometimes the system may produce sharp changes after instability, and even cause the collapse of the system, after the collapse of the system may be restored to the mesostable state through deep structural adjustment, or it may go to extinction.

There are two reasons why colloids are metastable: the first reason is that colloidal particles can be charged by adsorption, the same kind of colloidal particles have the same kind of cracking slag bright charge, and the residual charge of the same kind of electric beam will repel each other (to make the colloids sink together, it is necessary to overcome the repulsive force and eliminate the charge carried by the colloids). Reason 2: Colloidal particles are constantly doing Brownian motion, and when they act on the same force of gravity, they form a state of sedimentation equilibrium.

Stability refers to "the ability of a measuring instrument to maintain its metrological properties constant over time." In general, stability refers to the ability of a measuring instrument to have its metrological characteristics not change over time. If stability is not for time, but for other quantities, it should be clearly stated.

Stability can be quantitatively characterized, mainly to determine the relationship between metrological properties and changes over time. There are many types of automatic control systems, and the functions they perform vary greatly, some are used to control temperature changes, and some are used to track the flight trajectory of aircraft. But all systems have one thing in common in order to work properly, that is, to meet the requirements of stability.

The concept of stability.

Discernment - Since stability is important, how do you know if the system is stable? Cybernetics have come up with a number of theorems for determining the stability of a system. These theorems are based on the mathematical model of the system, according to the mathematical model of the shape of the judgment, after a certain calculation can be to draw a conclusion of stability or not, these theorems are more famous

The Rouse criterion, the Hurwitz criterion, and the three theorems of Liapzhiov. The first two are mainly used to determine whether the eigenvalue of the system is less than zero to determine whether the system is stable, and the descendants of the system are mainly determined by examining whether the energy of the system is attenuated.

Stability.

Question 1: Definition of structural stability of buildings 10 points.

Question 2: Definition of stable work Now it is the era of two-way choice, so stability can only be a relative work in which both parties are more satisfied, more trusted, and work for a longer time, but it is also impossible to be like the "iron rice bowl" and "golden rice bowl" in the past planned economy period.

Question 3: What does stability mean in chemistry It is not easy to volatilize、、、

Question 4: What is stability in material mechanics The definition of stability in material mechanics is the ability of a member to maintain its original equilibrium state under pressure and external load.

In order to ensure the normal operation of each component or mechanical part, the components and parts must meet the following requirements when the structure is subjected to load or mechanical transmission movement

No breakage, that is, it has sufficient strength;

The elastic deformation generated by the component should not exceed the allowable range of the project, that is, it should have sufficient stiffness; Repentance.

The balance in the original shape should be a stable balance, that is, the member will not lose stability. The requirements for strength, stiffness and qualitative stability are sometimes collectively referred to as strength requirements. The calculation and test of the components in these three aspects are collectively referred to as strength calculation and strength test.
