Liquefaction picture
Liquefaction was an image processing technique that was commonly used in Photoshop. When liquidating a picture, if the face of the person was liquified, it had to follow the principle of three courts and five eyes, symmetrical balance. The three courts referred to the upper court from the hairline to the brow bone, the middle court from the brow bone to the bottom of the nose, and the lower court from the bottom of the nose to the chin. These three parts should be equally spaced. The five eyes were based on the width of one eye. The distance between the two eyes was about the width of one eye. The outer corner of the eye to the junction of the ear and hair also occupied the width of one eye. When operating, first find the central axis. For example, use half of the face width as the central axis (because the nose may be tilted, the tip of the nose cannot be simply used as the central axis). It can be determined through some tool operation. It can also determine a horizontal reference line at the upper eyelid position. There were a few common operations when using the Liquefaction function in Photoshop.com. He could convert the image into a smart object for non-destructive editing, and then select "Filter-Liquefaction" to enter the Liquefaction menu command. If the liquefied face didn't want to affect the facial features, he could use the Freeze Mask Tool to cover the facial features before operating. There were some parameters on the right that could be adjusted according to habits. When PS detected a face, it would automatically switch to the portrait tool. When the mouse was placed on the face, the edge of the face automatically calculated by PS could be seen. The node on the line could be dragged to modify the shape of the face. When modifying, the parameters on the right side would change simultaneously. In the 2017 version, there were new changes in the eyes. The left eye's value could be adjusted through the chain icon link, and the right eye's value would change accordingly. You could also place the mouse on the eye position in the picture, and more node adjustments would appear. Pressing the "Shift" key could adjust the corresponding node of the other eye simultaneously. After adjustment, the value on the right would also change. There was also a "hidden function". When the mouse was placed on the cheek to form a cross, the left button could be pressed and dragged to move any part of the face. In addition, the effect of Liquefaction was more to restore the character to the real visual effect rather than excessive retouching. When retouching, it had to follow the natural laws of the human body structure and human aesthetics. The novel "Watching the Moon on Fish Island" is equally exciting.

Liquefaction applications
Liquefaction has the following applications: 1. ** Energy Sector ** - In terms of hydrogen energy, although there were many difficulties, hydrogen sublimation could help solve the problem of hydrogen storage and transportation. However, the energy consumption of hydrogen production and liquefied hydrogen was relatively high. One kilogram of hydrogen required about 50 kWh of electricity to produce hydrogen, and another 11 - 15 kWh of electricity was needed to liquify hydrogen. - In terms of traditional energy sources, there was a major breakthrough in coal direct sublimation technology. The application of this technology would help improve China's energy efficiency and promote the development of the energy field. - Liquefied oil gas is convenient for storage and transportation, and is convenient for civil and industrial use. 2. ** Medical field (not explicitly mentioned in the information provided, but supplemented from the perspective of general knowledge)** - Liquid nitrogen was used to liquify. The temperature of liquid nitrogen was extremely low, and it could be used for cryotherapies, such as removing warts, moles, and other pathological tissues on the skin. The low temperature could be used to cause the necrotic tissue to fall off. 3. ** Image editing field ** - In the PS software, the Liquefaction tool could be used to modify the image, such as adjusting the body proportion, drawing the jaw line, processing the facial light and shadow, etc. The image could be edited through various functions in the Liquefaction tool, such as the forward transformation tool, the freeze mask tool, etc., so that the image could achieve the ideal visual effect. 4. ** Physics teaching (based on junior high school physics knowledge points)** - Phenomena such as morning dew (water vapor in the air condenses when it freezes) and fog in the mountains (water vapor condenses to form small water droplets suspended in the air) could help students understand the concept of crystallization, the methods of crystallization (lowering temperature, compressing volume), and the heat release of crystallization.

liquefaction process
Liquefaction referred to the process of a substance changing from a gaseous state to a liquid state. This process would release heat to the outside world. There were two main methods to achieve liquification: one was to lower the temperature, and the other was to compress the volume. For some gases with higher critical points (such as hydrogen and natural gas), they could be liquefied by pressurizing them at room temperature, while gases with very low critical points such as hydrogen and nitrogen had to be deeply cooled to be liquefied at the same time. The critical temperature was the highest temperature at which a gas could be liquefied. In addition, there was also a situation where a substance changed from a solid state to a liquid state, which was called crystallization. This process could be achieved by increasing the temperature, reducing the pressure, or both. In this process, the distance between the molecules of the substance decreased, the interaction between the molecules increased, the volume of the substance decreased, and the density increased, making it easier to store, transport, and use.

What is Liquefaction?
Liquefaction referred to the process of a substance changing from a gaseous state to a liquid state. This process would release heat to the outside world. There were two ways to achieve liquification. One was to lower the temperature, and the other was to compress the volume. The critical temperature was the highest temperature at which a gas could be liquefied. However, there was also an explanation for the transformation of a substance from a solid state to a liquid state, which was called crystallization. In this process, it was achieved by increasing the temperature, reducing the pressure, or both. During the liquification process, the molecular distance of the substance decreased, and the interaction force between the molecules increased, thus reducing the volume of the substance and increasing its density, making it easier to store, transport, and use. For example, common gases such as hydrogen and natural gas could be liquefied at room temperature due to their high critical points, while gases such as hydrogen and nitrogen had very low critical points and had to be deeply cooled to be liquefied at the same time. In addition, the process of semen solidifying outside the body and then turning into liquid state is also called crystallization. Under normal circumstances, male semen is in a liquefied state when it is ejected outside the body. It will solidify into a jelly state in a very short time, and then gradually liquidize into liquid state after 10 - 30 minutes. There is also the raw material coal bed gas that has been compressed, pre-treated, and turned into liquid coal bed gas (liquefied coal bed gas) after low-temperature heat exchange.

The Essence of Liquefaction
Different substances liquefied for different reasons: - The essential reason for sand soil to liquify was that under the vibration of saturated silt and sand soil, the pore water pressure increased and the effective stress decreased. When the contact pressure between sand particles was equal to or close to zero, the friction resistance was also equal to or close to zero, thus showing the change from solid to liquid. - Fat Liquefaction could be caused by infection, poor suturing technique, inadequate incision protection, and other factors, which led to the appearance of fat Liquefaction in the postoperative wound. - Whether semen could be liquefied or not was mainly related to the substances secreted by the vesicle and the bladder. The secretion of the bladder directly affected the semen's liquefied state. The secretion of the vesicle, bladder, and local urethras would affect the secretion of the secretion of The novel " Watching the Moon on Fish Island " is equally exciting.

Liquefaction and vaporizing
Liquefaction referred to the process of a substance changing from a gaseous state to a liquid state, which would release heat to the outside world. There were two ways to achieve liquification. One was to lower the temperature. As long as the scientific conditions allowed, any gas could be liquefied when the temperature was low enough. The other was to compress the volume. Some gases could be liquefied by compressing the volume at room temperature. Boilification referred to the phase change process of a substance from a liquid to a gas. This process required the absorption of heat. There were two forms of vaporizing: evaporating and boiling. Evaporizing was a phenomenon of vaporizing on the surface of a liquid. It was a slow vaporizing method that could be carried out at any temperature. The temperature would drop during the evaporating process, and it had the effect of heat absorption and cooling. Its speed was related to the temperature of the liquid, the surface area of the liquid, the speed of air flow above the surface of the liquid, the humidity of the air, and the type of liquid. Boiling was a phenomenon of intense vaporizing that occurred in the body and surface of the liquid when the saturated vapor pressure was equal to the external pressure. When the liquid was boiling, it absorbed heat but the temperature remained unchanged. The boiling point of different liquids was generally different. The boiling point of the liquid was also related to the air pressure on the surface of the liquid. The boiling point increased when the pressure increased, and the boiling point decreased when the pressure decreased. Liquefaction and vaporizing were inverse processes.
