Meaning of stress 10, what is the definition of stress?

Next, some words such as "depressed" and "depressed" are popular... For example, most people walk on the road and are afraid of others looking at him or her, or just pretend to be in a hurry and pretend that no one is afraid, this is what I observed, and now we will talk about it

First, let's analyze the environment in which stress is generated: The following are divided into several categories:

Office workers] (1): busy at work every day, no rest, after returning home, you have to cook, take care of the children, take care of housework, (2) criticized by the leader, blamed, discriminated against by colleagues, work is not very smooth, afraid that you will not do well at work is always annoying, emotional] emotional cracks = grief Parents prevent you from meeting or marrying your beloved The person you love has passed away The person you love very much does not love you anymore.

In terms of family] cracks in marriage and domestic violence

Maybe it's a problem with the relationship between the two of you.

This kind of problem needs to be clarified. You just say you know what's going on.

There are many kinds of stress.

Stress is the negative feelings and negative beliefs that arise when a person is unable to face the external environment.

In physics, the term pressure generally refers to the force that is perpendicular to the surface and points to the surface of the object, such as in the Qing Dynasty's "Diary of the Four Kingdoms: The Ninth Month of the Seventeenth Year of Guangxu", "Those who are on the earth today are accustomed to seeing heavy objects falling." This is nothing but the pressure of the heavens, and the suction of the earth is the ears."

Pressure also refers to the power to coerce or subdue people, Lao She's "Four Generations in the Same Hall" in the sentence "The second brother saw that the eldest brother no longer spoke, and ran to talk to his grandfather, in order to teach the old man to use a little pressure on the boss".

synonyms

一、重pressure [ zhòng yā ]

It is called a heavy pressure or burden.

Lu Xun's "South and North Mobilization · Self-Selected Collection Self-Preface": "The works that will give readers a 'sense of pressure' are specially withdrawn. ”

2. Oppression [ yā pò ].

1. Use violence or power to force others to obey you.

2. Applying pressure to a certain part of an organic object.

Chapter 6 of the first part of Yang Mo's "Song of Youth": "My family oppressed me, and I fled to society; But society, like the family, still smells of decay and mildew, and it is black. ”

It is the reason why people face one or a class of things: if I can't do it well, I will. Specifics ...thoughts trigger negative feelings. But the performance does not have to be negative, it can be positive and good.

1. Definition of static pressure:

The pressure of the fluid acting vertically on the wall of the vessel is called static pressure, which is expressed in PJ and is measured in millimeters of water column. The static pressure greater than the ambient atmospheric pressure is positive, and the static pressure is negative when it is less than the ambient atmospheric pressure.

2. Definition of dynamic pressure:

When a fluid flows in a pipe or air duct, the pressure due to velocity is called a dynamic pressure or velocity head. The dynamic pressure value is always positive, expressed in pd, and the unit is in millimeters of water.

3. Definition of full pressure:

Total pressure refers to the algebraic sum of static pressure and dynamic pressure at a certain point, i.e., py=pd+pj unit is also millimeter water column.

Generally, dynamic pressure, static pressure and full pressure are suitable for centrifugal fans and boiler flue gas ducts. For example, the static pressure measurement point on the boiler flue gas duct is drawn from the wall of the flue gas duct, so the flue gas pressure gauge on the boiler dashboard indicates only the static pressure.

Due to the small dynamic pressure value in the flue gas duct, it is sufficient to measure only the static value of each point in the boiler operation.

PA is the unit of pressure.

Formula: p=f s

p denotes pressure in pascal (pa).

f denotes pressure, and the mountain is known in Newton (n).

s represents the stressed area, in square meters ().

200kpa is 200000nm2=20000 kg sqm. The pressure equivalent to an area per square meter is 20,000 kg.

The unit of pressure in engineering is kilograms, which refers to kilograms square centimeters. According to 1 kg force = 10n, 1 kg square dismantling centimeter = 100,000pa.

So 200kpa = 2 kg square centimeters. i.e. 2 kg pressure.

Pressure, as a physical term, refers to the force that occurs on the contact surface of two objects; As a psychological term, stress refers to a cognitive and behavioral experience process composed of psychological stressors and psychological stress responses. In layman's terms, stress is the negative feelings and negative beliefs that arise from a person's inability to face the external environment.

The meaning of stress.

In physics, the term pressure generally refers to the force experienced by an object that is perpendicular to the surface and points towards the surface, as in the Qing Dynasty.

In the Diary of the Four Kingdoms, the ninth day of the first month of the seventeenth year of Guangxu, "Those who are on the earth today are accustomed to seeing heavy objects falling. This is nothing but the pressure of the heavens, and the suction of the earth is the ears."

Pressure also refers to the power to coerce or subdue people, such as the sentence "The second brother sees that the eldest brother no longer speaks, and runs to talk to his grandfather, in order to teach the old man to use a little pressure on the boss".

The pressures of modern society are mainly at work, life or personal character.

Stress is a cognitive and behavioral process composed of psychological stressors and psychological stress responses.

Stress is a foreign word, derived from the Latin word "stringere", which originally meant pain. The word now written is an abbreviation of "distress." It has long been recognized that stress affects people's physical and mental health, with the meaning of "tension, stress, stress", etc.

Psychologist Han Selye was the first to use the term "stress". The English word "pressure" is derived from the Latin stringere, which means "to expand, to extend, to extract", etc. It has also been suggested that the word stress is derived from the Old French word for "distress", which means "to be placed in the midst of narrowness and oppression".

Thus, in medieval English, the word "stress" came in the form of "distress", which meant "to make pain", "to make sorrow", or to express it as "something that causes pain and sorrow". "Pressure" was first a concept of physics, also known as physical pressure.
