What is Wailing Valley and why is this happening

If you can record sound with a magnetic field and electricity, you also need a speaker.

As for the sound of war, it is noisy and mostly roaring in the distance, so it is easy to be misunderstood.

Natural sounds are often found in nature, but it is difficult to record sounds at a particular time.

There are many wind-eroded landforms on the Silk Road"Ghost town"The perennial wind carries gravel, and there is still space in the middle of the rectangular shape that cuts the rock into pieces, which looks like a collapsed house, and the directional wind at a specific moment every day will blow a low whistle in some holes, and listen to it from a distance, as if the ghost is crying, which is creepy, most of the natural sounds involving the ghost crying are this truth, and some are because the cavity under the ground is rubbed under the weight of people or animals, such as the Shaming Mountain in Dunhuang.

It is I who hurts the peasants.

It has been a saying that has been circulating in the country for a long time.

He describes this kind of scripture.

Economic phenomenon: In the year of the harvest, the farmer's income right is reduced. This can be explained by the principle of elasticity.

The fundamental reason for this phenomenon is that agricultural products are often commodities that lack the elasticity of demand, and the bumper harvest of agricultural products increases the supply, and under the effect of inelastic demand, the equilibrium of agricultural products has declined significantly, and the decline in the equilibrium of agricultural products is greater than the increase in the equilibrium of agricultural products, which finally leads to the decrease in the total income of farmers.

It's easy to see if you draw a graph of the supply and demand curve yourself)

I looked at Director XX and Bobai

Shi's essay knows why China's Professor Zhi wants to sweep the floor in the United States to live.

According to the IMF research report in 04, the main reason why some countries or policies have set up a series of facilities to protect grain prices in order to protect the interests of local farmers. However, this behavior will only prevent local farmers from effectively integrating resources, resulting in more and more poverty as they are protected.

In the case of a bumper harvest, the income of the peasants decreases due to the price of grain**.

Because agricultural products are commodities with inelastic demand, a bumper harvest will not increase demand in proportion to the price of food**.

Due to TR PQ, when ** declines, the increase in demand is less than the decrease in **, so that the total income decreases and farmers suffer losses.

Grain cheapness hurts farmers: The grain is too low, causing damage to farmers.

There are many factors that affect food, but the most critical factor is "yield".

Why is the key factor in relation to production and not mentioned "demand"? This is because food, as a physiological necessity, has a rigid demand.

When the demand is relatively stable, the greater the supply to the market, the lower its **: (supply and demand diagram).

When the p point is reached, it is a production transaction** - supply and demand are in balance.

The demand curve can be seen: when the number is more, the lower its **; The supply curve shows that the higher it is, the more goods it will bring to market.

The current situation is that the demand is relatively constant, so when the supply is too much (high output), it will inevitably decline in order to ** commodity (forming a market game), and when it is too low, it will inevitably cause a sharp decrease in the income of the supply side, even lower than the year when the harvest is not good.

At the beginning, the main income of farmers came from grain, and when the only income was impacted, the overall income of farmers would be impacted.

Extension: Therefore, one of the functions of the modern economy is to emphasize expenditure, and one of the functions of the market is to intervene in the market when the market economy cannot control it.

For example, when the grain output of farmers is too high, the grain reserve can be opened and a large amount of grain can be purchased, so as to increase market demand and stabilize the grain market.

For this kind of necessities of life, the ** change has little impact on people's demand, that is, if the grain is cheap in time, the number of people who buy it will not increase much, so it hurts farmers.

The diagram is not easy to do, so I'll analyze it.

If a grain price is set below the equilibrium, it will reduce the supply of grain to the peasants and affect their enthusiasm for production.

This also involves a country's foreign policy, the school of heavy agricultural economics believes that if the protection policy is realized, and the world of grain is not carried out, then even if there is a bumper harvest of grain, due to domestic oversupply, the price of grain will plummet and hurt the peasants' enthusiasm for production.

"Grain cheapness hurts peasants" is a classic problem in economics. How much a farmer can sell his grain after harvesting depends on two factors: the output and the price of grain, which are the product of the two.

But these two variables are not independent, but are interrelated, and their correlation is determined by a downward sloping line of demand for food. That is, the lower the demand, the greater the demand; **The higher it is, the less demand it will have. It should also be noted that the food demand line lacks elasticity, that is, the demand is not very sensitive to changes in **.

When the price of food is **, the demand for food increases, but not by much. The basic truth lies in the fact that food is a necessity, and the demand for food is mainly determined by the physiological demand for food.

The graph is a curve with little elasticity.

You can refer to the section on microeconomics that stipulates the minimum.

Supply and demand affect **, ** affect supply and demand, and guide people to adjust the factors of production.

It also shows that grain is a commodity with less elasticity of demand.

"Grain cheapness hurts farmers" means that a bumper harvest of grain not only does not benefit the peasants, but also leads to a decrease in income due to the decline in grain. This is reflected in the elasticity theory of economics, where the demand for agricultural products lacks both elasticity and elasticity of demand, that is, the amount of demand is not very sensitive to changes in the economy. In the absence of major changes in demand, the decline of ** will lead to a decrease in income.

Gu cheap"It refers to the increase in production in a bumper harvest year, but the demand remains unchanged, resulting in a decline in grain**; "Hurting farmers" means that the increase in income is not enough to make up for the decrease in income caused by the decline in income, and the result is that the total income of farmers not only cannot increase but declines, that is, the elasticity is small, and the increase in production does not increase income. Generally speaking, it is income = **x sales, at this time, ** decreases, sales remain unchanged, so income also decreases, harming the interests of farmers.

Explained by economic principles, the fundamental reason is that agricultural products are often commodities that lack the elasticity of demand.

Hunger refers to the symptoms of hyperphagia and large amounts of food, but hunger soon after eating. It is also known as eating too much and being hungry.

Those who are good at eating and drinking, and who are emaciated are more common in thirst disease. It is caused by the stomach being hot and too rotten.

Those who eliminate grain and hunger, and have loose stools, have a strong stomach and a weak spleen. If the stomach is strong, the stomach is ripe and the function is excessive, so it is good for hunger; If the spleen is weak, the spleen is weak, so the stool is loose.

The son steals motherhood. In the mother-child relationship between the five organs, the five elements are used to illustrate the symbiosis between the five organs, and it is said that the child is sick and tired of the mother. It is mostly used to explain the pathology of the interaction of the five visceral deficiency diseases. For example, when the weakness of the lung qi develops to a certain extent, it may affect the function of the spleen qi movement.

It has been confirmed by investigation that in addition to the strong magnetic Huwangzhao basalt body of the large Triassic volcanic eruption, there are also more than 30 iron ore and quartzite bodies in the Devil's Valley strata. It is precisely because of the electromagnetic effect of the strong magnetic field formed by the underground rock mass and the iron ore belt here that the electric charge in the lightning cloud is attracted, so that the air discharge and the formation of the thunderstorm phenomenon are formed.
