What is the noun explanation of low temperature hazards? Explanation of moderate temperature terms

Hypothermia includes: freezing (hypothermia), in which the body temperature drops to the point where it is likely to cause injury; mild frostbite, which is a local epidermal injury to the body; Frostbite, frostbite is the necrosis of tissues in a part of the body. Chilblains and trench feet are also damage caused by low temperatures.

Cryogenic damage. Frostbite and freezing to death are caused by low temperature, causing blood circulation disorders, which is called frostbite. According to the degree of frostbite, it can be divided into 3 degrees:

Frostbite in the first degree is erythema, frostbite in the second degree is blistering, and frostbite in the third degree is necrosis. When low temperature acts on the whole body, if the human body is not warm enough, the body temperature will be released at an accelerated pace, and the heat production will not compensate for the heat dissipation, and the body temperature regulation will be disordered, and the body temperature will begin to drop. When it is reduced to below 35, the thinking ability is reduced, and the body is extremely weak and fatigued; When below 30, consciousness and irregular heart rate; Below 26 is lethal.

Freezing death is mostly caused by disasters, and most of them occur in the cold areas and plateau areas of the northern part of the country. It is common to die of freezing after being drunk, and occasionally it is seen in cases of abuse. The body of the frozen dead is often stiff and the posture is often curled up; The corpse spots (see corpse phenomenon) are bright red, and if the corpse is placed at room temperature to warm up, the corpse spots can turn purple red.

The autopsy showed that the blood of the lungs and left heart was bright red, and the blood of the right heart was dark red; diffuse punctate bleeding of brown or dark brown pinhead size to pea size in the gastric mucosa; The volume of the cranial cavity is expanded due to freezing, and the skull sutures are separated; Changes such as pulmonary congestion, hemorrhage, edema, and submembranial punctate may also be seen.

Interpretation of the thermometer.

thermometer;Calorimeter] is an instrument for determining the temperature of the Celsius thermometer explained in detail also known as " thermometer ". An instrument for measuring temperature. There are thermometers, cold and heat meters, etc.

It is a closed glass tube, the lower end is cylindrical or spherical, and it is filled with mercury or alcohol to form a liquid column, which expands and contracts with the rise and fall of temperature, and the temperature value can be seen according to the scale where the top of the liquid column is located. There are two main scales: Celsius ( ) and Fahrenheit ( ), which are generally expressed in degrees Celsius. It is also used as a metaphor to refer to something that can be measured to change.

Lao She, "Four Generations in the Same Hall" 29: "The old lady saw that her son's face and spirit were wrong. A mother's heart is a thermometer of her children's feelings.

The absolute minimum temperature is the extreme minimum temperature over the entire observation period, which characterizes the temperature limit of an area. To obtain a relatively reliable absolute minimum temperature, a fairly long observation period (more than 30 years) is required. Absolute minimum temperature, also known as "extreme minimum temperature".

Refers to the lowest value of the lowest temperature that can occur at a given time in a calendar year, such as a year, month, and day. For example, the monthly and annual extreme minimum temperature is the extreme value selected from the minimum temperature value of the whole month or each day of the year: the extreme minimum temperature of a month and year is the extreme value selected from the minimum temperature value of a month and year in the calendar year.

It's just that it's theoretically feasible and hasn't been reached in practice.

The absolute minimum temperature of the Earth's matter is, which is also the lowest temperature that the matter can reach, also known as absolute zero. With the development of human science and technology, absolute zero can only be infinitely approached, but it cannot be reached.
