1. Multi-story public stands typically account for around 10%, and high-rise public stands are expected to reach 20%. The same house is 10 square meters less, which means you spend 10% more to buy a high-rise building. erect the building. On the stand.
2. The management fee for multi-story properties is generally less than 1 yuan and more than 0.6-0.8 yuan. There are no elevator charges or secondary water supply charges. Property fees for high-rise buildings generally exceed 1 yuan and are most commonly between 1.1 and 1.5 yuan. Long-term ownership costs are indeed a heavy burden.
3. Public maintenance funds for multi-storey buildings are 1%, while for high-rise buildings it is 2%.
4. Multi-story house types are relatively reasonable. Hethere are two households in a unit. Most multi-story houses are transparent from north to south, while there are very few houses with it. north-south transparency in high-rise buildings.
5. Multi-story buildings have wider spacing and better lighting.
6. The floor space ratio of multi-story buildings is even lower, generally only 1/2 to 1/3 of high-rise buildings.
7. Solar power can usually be installed on multiple floors, but it is absolutely not allowed on high-rise buildings. Solar energy can also save a lot of gas or electricity bills in a month.
8. There is a power outage on several floors, but there is always water unless there is an outage. If there is a power outage in a high-rise building, even the elevator cannot be used. If you live aboveIf you are on the 20th floor and have to climb the stairs to get home every day, think about it, what would that be like? I guess life would be worse than death.
In brief
Buying high-rise buildings is not the first choice
Buying several floors is still a good choice
Take the seven colors of the rainbow as an example. The “light” of the sun is made up of seven colors: red, orange, yellow, green, blue, indigo and violet. Light is an electromagnetic wave and the color will be different depending on the wavelength. Among them, red light has the longest wavelength and violet light has the shortest, so the wavelengths of the seven colors are red, orange, yellow, green, blue, l indigo and violet. Because violet light has a short wavelength, its refractive amplitude is greater than that of light with longer wavelengths like light.re red. This is why the violet light is inside the rainbow and the red light is outside.
Let’s put the focus back on the sun itself. You must be wondering how green can this be? After all, when you look at the sunset, the sun is obviously white, orange and red, but it's not green anyway! Indeed, at night, when the sun shines obliquely, the distance through the atmosphere lengthens and the number of encounters with obstacles (air, etc.) increases. ) are becoming more frequent. Light with shorter wavelengths in other colors is scattered at high altitudes and practically cannot reach the ground. Only red light and orange light with longer wavelengths reach the ground, so the sun will appear orange-red.
Taking the sun as a star, its radiation peak is located right at the junction of blue and green in the spectrum, dSo from the point of view of light, the sun is a green star! Or better yet, turquoise stars. The temperature of the star is also directly reflected in the color it displays. For the Sun, its surface temperature is around 6,000 degrees. As mentioned earlier, due to human eye color discrimination error, we have always believed that the sun is actually yellow and white.
As mentioned before, the longer the wavelength of light, the more it can pass through obstacles in the atmosphere (such as oxygen, nitrogen molecules, dust, vapor water); blue, indigo, and violet light have shorter wavelengths and scatter easily when encountering obstacles in the atmosphere. So when we look at sunlight, the blue-green color is blurred, which is why we think it is white. I know you might say: isn't heavennot blue too? This is because the human eye is more sensitive to blue, so what we usually see is blue skies.
Is there any chance we can see a green sun? If we summarize the above statement, at sunrise or sunset, the first or last thing we see should be blue light. But blue light scatters easily in the air, making it difficult to see. Typically what we see is green light, which has a slightly longer wavelength than blue light. So, if you have the opportunity to watch the sunrise on the beach on a clear day, when only a small part of the sun is above the horizon and the air quality is clear, you can see the green sun! But only a few seconds!
This should be the most interesting little bit of knowledge you've seen today! No matter how complicated it is. In short, the cThe color of light changes due to temperature and wavelength. The wavelength of light that the human eye can see is limited, which is why the sun we usually see is not green!
