How can you put something together and divide it accurately?

I think dear landlord is happy to analyze your problem for you, I have encountered it before, the following is my own, I hope to help the landlord 1Look at the world with another eye, not everyone in this world is very smooth, just look at how you solve it, for example, you were hit by someone when you were walking, others apologized to you, sometimes you still feel very angry, but you didn't expect that the person who hit you was actually more uncomfortable than you, or think about the sentence "Happy is also a day, unhappy is also a day, why not be happy every day". 2.

If you think that you are in a bad mood, you will be in a bad mood, then you don't need to think about it, if you still want to, then keep yourself busy, let yourself have no time to think about it, let yourself live every minute to the fullest, and then don't fall in love with the bed after waking up in the morning, get up when you wake up, get busy, open the window, breathe in the fresh morning air, relax your whole body, and let yourself imagine a happy little angel ......3.Choose a place with fresh air, quiet surroundings, soft light, undisturbed and free movement, and take a position that you feel comfortable in, standing, sitting or lying down. 4.

Move some large joints and muscles of the body, the speed should be even and slow when doing it, and the action does not need to have a certain format, as long as you feel the joints let go and the muscles relax. 5.Take a deep breath, inhale slowly and exhale slowly, saying "relax" in your mind whenever you exhale.

6.Focus your attention on some everyday objects. For example, look at a flower, a little candlelight, or anything soft and beautiful, and look closely at its subtleties.

Light some spices and inhale the aroma of it. 7.Close your eyes and try to imagine some tranquil and beautiful scenes, such as blue waters, golden sandy beaches, white clouds, mountains and water.

8.Do activities that you enjoy that have nothing to do with the specific things at hand. For example, swimming, taking a hot bath, shopping, listening, watching TV, etc.

9.Life is easy, life is easy, life is not easy. Don't worry, there are a lot of people in this society who are almost like you, but they are all living happily, not everyone can succeed, as long as you work hard to treat everything, take life seriously, as long as you take every day seriously, no matter how your life is, I believe it is wonderful.

It is recommended that the landlord use different colors of the classified shelves, so that it is OK.

First of all, uneven pillow cotton is relatively common in life, and there is no need to worry too much about this situation, you can ravage the pillow left and right, and there will be a certain alleviating effect on this situation. However, if there is no way, you can disassemble the jacket of the pillow, straighten the cotton inside, and then put it in, which is also a good method.

Secondly, there are many pillow materials, and there are many popular types of cotton on the market, such as space cotton and other cotton, according to the different types of cotton, the selection methods are also different, and there are some pillows that will not appear uneven cotton, change a pillow, you don't have to worry about the occurrence of such problems.

Because it is the fiber characteristic of cotton, it is a filler that is not easy to clean. Therefore, long-term use, coupled with negligent maintenance, will allow the cotton pillow to deposit dust, the compressive performance of cotton fiber is poor, if it is pure cotton, long-term use may occur compaction, and the elasticity of the cotton pillow is poor.

If you have the money to buy another one, you don't have the money to make do with it.

Take it to the sun and expose it, if it is good cotton, it will be fluffy, disassemble and tear a little bit and reassemble it.

Sew it line by line with thread, and that's it.

Iron filings can be sucked away with magnets.

A magnet is a substance that can attract or repel each other, and if the tiny molecules inside an object can be arranged in the same direction, it will become a magnet.

The composition is iron, cobalt, nickel and other atomic structures are special, the atoms themselves have magnetic moments, and the general arrangement of these mineral molecules is chaotic.

The magnetic regions do not show magnetism when they affect each other, but under the guidance of external forces (such as magnetic fields), the molecular arrangement tends to be in the same direction, which is commonly known as magnets.

Iron, cobalt, nickel, is the most commonly used magnetic substance, basically magnets are divided into permanent magnets and soft iron, permanent magnets are added to strong magnetism, so that the spin of magnetic substances and the angular momentum of electrons are arranged in a fixed direction, soft magnetism is to add current (also a method of adding magnetic force) and other currents to remove soft iron will slowly lose magnetism.

A magnet is an object that can generate a magnetic field, a magnetic dipole, which can attract ferromagnetic substances such as iron, nickel, cobalt and other metals.

The magnetic pole is determined by hanging a magnet with a thin line, the magnetic pole pointing to the north is called the north pole or n pole, and the magnetic pole pointing to the south is the guide pole or the s pole. (If we think of the Earth as a big magnet, then the current geomagnetic north pole of the earth is the s pole, and the geomagnetic south pole is the n pole.) Magnets attract at opposite poles and repel at the same poles.

The compass pole attracts the north pole, the compass pole repels the compass pole, and the north pole repels the north pole.

Iron filings are metals, and magnets are used to suck away iron filings.

Soak iron filings and charcoal foam in water.

You're all wrong, and you're right: first this and then that.

I don't know, I really don't know.

Suck up the iron filings with an iron.

Iron filings can be sucked away with magnets.

Use a magnet to suck the iron filings away.

Physical method Attract with magnets.

Chemical method: Heating at high temperature or dilute sulfuric acid.

Iron filings can be sucked away with magnets.

Iron filings are soluble in hydrochloric acid, sulfuric acid and dilute nitric acid. Oleum nitric acid "passivates" iron, creating an oxide film on the surface that prevents it from continuing to dissolve in acid. Insoluble in cold water, hot water, alkali, ethanol and ether.

Production personnel should wear work clothes, dust masks and other labor protection supplies. The production equipment should be sealed, the workshop should be well ventilated, and attention should be paid to dustproof.

Use a magnet to suck the iron filings away to separate the iron filings from the charcoal.

The principle is: the composition of the magnet is iron, cobalt, nickel and other atoms, and the internal structure of the atoms is relatively special, and it itself has a magnetic moment. Magnets are capable of generating magnetic fields and have the property of attracting ferromagnetic materials such as iron, nickel, cobalt, and other metals.

Magnets are not invented by man, they are natural magnetite. The ancient Greeks and Chinese discovered that there is a natural magnetized stone in nature and called it "magnet stone". The stone magically picks up small pieces of iron, and always points in the same direction after swinging at will.

Add acid to filter, attract with a magnet

So use a magnet to suck the iron and carbon away.

Understand the meaning of that song.

Pay attention to the collection of auspicious deeds and take the lift not to get lost.

You can try scrubbing with toothpaste, which has a strong stain removal ability and will not damage the cortex. If you really can't get rid of it, rub it with a white crayon, which will somewhat cover up the yellow mark, and you won't notice it if you don't pay attention.

1. Wash with chlorine-containing detergents such as Bilang and Tide, soak for more than 15 minutes, and dry in the sun after washing.

2. When washing, add 1 2 drops of pure blue ink to the water and soak evenly.

3.Soak the boiled spinach in water to cool it and have an unexpected effect (it must be whitening): Sediba - Apprentice Magician Level 2 7-10 12:52

When the water is released, the iron sinks and the carbon floats.

Use an electromagnet to suck out the iron pin.
