What does a void describe and what does a hollow mean Explanation of hollowness

Hollow 1Nothing; Emptiness. Song Lin Kui.

The preface to the poem "Deep Miscellaneous": "The contemptible husband is not, the chest and abdomen are hollow, and there is nothing to store. Zhou Libo.

"Great Changes in the Mountains and Towns" on: "In the middle of the night, she got up alone, sneaked into the empty and dark hall, and practiced her eloquence in a low voice. Liu Qing, "History of Entrepreneurship".

Chapter 19 of the first part: "Without Lan Lan, how empty their life in the past ten years should be!" ”

2.Taoist language. It is said to be the realm of the void of the vitality of the incarnation. Tang Wuyun "You Xian" poem No. 24: "The hollow condenses the true essence, but it is the reality in the void." "Seven Signatures of the Clouds".

Volume 2: "The vitality is within the recklessness, outside the darkness, and is born in the void." ”

3.It is said to be subtle and subtle. Former Shu Du Guangting "Jiazhou Wang Servant Shoots Five Fu Town House Words": "Condense the breath of nature and turn it into an empty text." ”

4.Onomatopoeia. Tang Cao Tang "Little Wandering Immortal Poems" No. 37.

Whoever swam in front of the Eight Seas Gate, hollow in the wind and rain. ”

5.Describe the emptiness of the voice. Ai Qing, "The Wilderness".

Poem: "The woodpecker uses its beak to knock on the hollow sound of an ancient tree." Tian Ye "Burning Island".

The hollow and heavy sound of the guard's leather shoes, outside the door, walked over, walked over. ”

6.Describe the dazed eyes. Zhang Tianyi, "Hatred": "Six eyes staring at the big man with a vacant look. Those three mouths were speechless. ”

7.Pathological terms. A depression or pore left in the original place after the necrotic or liquefied lesion material in the organ tissue is discharged.

Cavity; Tunnel. "Mozi Beicheng Gate": "In today's world, there are often attackers, such as proximity, hooks, rushes, ladders, mounds, water, holes, protrusions, hollows, ant attachments, slurs, and xuanches. ”

8.In astronomy, a void refers to the space between filamentous structures, and together with the filamentous structure, a void is the largest structure in the universe. The hole contains little or no galaxies.

A typical cavity is about 11 to 150 million parsecs in diameter; In particular, large holes that lack superclusters are often referred to as superholes or superholes.

If you describe an article as "empty", it means that the article has no central idea and does not know what to express, of course, it means that the article is not easy to pull!

The idea is empty, the content of the article is empty.

Emptiness means that the article has no connotation, and the meaning expressed is ambiguous, and it also refers to the lack of thought and soul.

No spirit, no soul.

1. Void is a word, pronounced kōng dòng. Meaning: (1) Voids within an object. (2) Lack of substance. (3) Emptiness without connotation.

2. In addition, scientists have discovered holes in the universe with a diameter of 1 billion light-years. In this hole, there are no stars, no planets, no nebulae and no interstellar gases, and what is even more strange is that the cosmic microwave background radiation temperature in this region is also low. Normally, when the background microwave of the universe passes through the cosmic space, it will gain a certain amount of energy and the temperature will rise.

In everyone's imagination, hundreds of billions of galaxies must crowd the entire universe, but in fact, there are still many very sparsely distributed galaxies in our universe, and scientists generally call this kind of cosmic space "holes". Scientific detection data show that if humans can fly out of the Milky Way, then 700 million light-years away, we can encounter a space-time region with a diameter of about 100 million light-years, which is the famous "Pastoral Hollow". It is called a hole because scientists have found that there are so few galaxies in this vast space, that there are only about 60 galaxies in a range of 100 million light-years.

There is no gap without comparison, and you must know that in other directions of the universe, in the same size of space, the average number of galaxies is generally more than 10,000.

The universe is empty. In addition to their scarcity, the 60 galaxies in the Cavity of Pasture are also very far apart, with an average distance of more than 10 million light-years. By comparison, the Milky Way is only 2.2 million light-years away from the nearby Andromeda Galaxy.

If there were an intelligent civilization on one of the planets in the Pastoral Cavity, for a long time, scientists of that civilization might have thought that there was only one galaxy in the universe. If humanity had been in the Milky Way galaxy at the center of the Pasture Hollow, scientists would not have been able to discover any extragalactic galaxies before the 60s of the 20th century.

Shepherd's Hollow.

Many diseases can form cavities in the process of development, and the cavities and morphologies of different diseases have their own characteristics. A good understanding of the radiographic features of the cavity is important for the differential diagnosis of the disease. CT scan is more clearly identified than plain radiographs to identify the presence of cavities and make a qualitative diagnosis.

High-resolution CT can further visualize the subtle manifestations of cavities and provide more imaging information. Pathologically, cavitation is formed by the expulsion of the liquefied components of the lesion through the bronchi and the introduction of air after necrosis. Those who do not introduce gas into the lesion are not cavitations and are called necrosis or abscesses.

For neoplastic lesions, the central part of the lesion is necrosis and liquefaction of the tumor tissue, and after the lesion communicates with the outside world, it can be co-infected.

For inflammatory diseases, cavities are formed after liquefaction of purulent lesions of the lungs or tuberculous caseous lesions. The wall of the cavity retains the pathological features of the original lesion. Cavities are divided into single and multiple cavities according to their number, and according to morphology, they are divided into intrapulmonary cavities and cavities within the consolidation of lung lobes or lung segments.

The hole in the ozone layer appears over the polar regions.

The ozone hole usually occurs in the polar regions of the Earth, namely the South and North Poles. This is due to the high quality of solar radiation in the atmosphere in these areas, coupled with the special climatic conditions in these areas, where natural conditions interact with human activities to lead to the loss of the ozone layer. Especially in the spring in Antarctica, severe ozone holes often occur.

The Antarctic continent has high latitude, high altitude, strong glacial reflectivity, special annular vortex and low temperature conditions, the annular vortex encloses the Antarctic continent, and the ozone-rich muhall air flow from the north cannot enter the sky above it. The low temperature caused numerous ice crystal clouds in the atmosphere over Antarctica, and the ice crystals in the clouds continued to absorb chlorofluorocarbon gas, and the concentration became higher and higher, which accelerated the destruction of ozone.

The destruction of the ozone layer has brought great harm to the earth's environment and human health. First of all, the reduction of ozone and the increase of ultraviolet rays to the ground will damage the immunity of people and animals, and it is easy to break out epidemic infectious diseases, which will cause cancer, cataracts and blindness in the eyes, and stagnation of growth. Secondly, short-wave ultraviolet rays can destroy the chlorophyll of plants, affect the photosynthesis of plants, and reduce crop yields.

There are several ways to protect the ozone layer:

1. Reduce greenhouse gas emissions: Greenhouse gases are one of the main causes of ozone layer depletion, so reducing greenhouse gas emissions can reduce the risk of ozone layer depletion. Reducing greenhouse gas emissions can be achieved through the use of renewable energy, high energy efficiency of wax dust, and the promotion of low-carbon travel.

2. Control the use of chemicals: Some chemicals can destroy the ozone layer, such as chlorofluorocarbons. Therefore, controlling the use of these chemicals is an important measure to protect the ozone layer.

This can be achieved by strengthening the formulation and enforcement of environmental protection laws and regulations, and strengthening the supervision of hazardous chemicals.

3. Strengthen environmental protection publicity and education: Strengthening environmental protection publicity and education can improve the public's awareness of environmental protection and promote people to take environmental protection actions. The importance of protecting the ozone layer and concrete actions can be conveyed to the public through various publicity channels, such as television, newspapers, the Internet, etc.

4. Development of environmental protection technology: The development of environmental protection technology can improve the efficiency of resource utilization and reduce pollution emissions, thereby reducing the damage to the ozone layer. It can be achieved by increasing investment in research and development of environmental protection technology and strengthening the promotion and application of environmental protection technology.
