How many days does it take to go to Jingsheng in Taiyuan center

1. As long as the mail or express to Taiyuan, generally the next day will be able to receive
2. Generally speaking, you can receive the notice on the same day!
3. By coach, you can pass Jingjie directly. If you take the train, you have to change two trains after getting off the train. It's more troublesome.
4. Has your mail arrived? For Mao, mine has been in Taiyuan processing center. It hasn't been delivered up to now
5. It takes a day or a night to be quick, but a day or a night to be slow
I'm afraid to be successful in Changsha. Yunda and Shentong are faster than him, and the prices are almost the same. SF is the fastest, but the most expensive.

6. SF express from Taiyuan distribution center to Jincheng City, under normal conditions, usually arrive the next day to receive
it's about 300 kilometers from Taiyuan distribution center to Jincheng City, which is still quite far away, but now the expressway is very developed and fast
If SF express is from Taiyuan distribution center to Jincheng City, normally, it will arrive the next day, not more than 2 days.

7. From the origin of the word: when the name of orientation was determined, the direction of the sun rising was defined as the East, which is still in use today
explanation from the perspective of Geographical Science: that is because the rotation of the earth is from west to East. So we stand on the earth and see that it's caused by the rotation of the earth from west to East< In addition,
the rotation of the earth around its axis from west to East. The earth rotation is an important movement form of the earth. The average angular velocity of the earth rotation is 7.292 × 10-5 radians per second, and the linear velocity of rotation on the earth's equator is 465 meters per second. Generally speaking, the rotation of the earth is uniform. But precise astronomical observation shows that there are three different changes in the earth's rotation< 1. Toothpick method
first fill a basin with water and put it in a horizontal place where it is not easy to vibrate. After the water is still, gently put down a thin wooden toothpick and make a mark on one end of the toothpick. Remember the location of the toothpick. After a few hours (preferably more than 10 hours), you will find that the toothpick has turned a certain angle, In the northern hemisphere, the toothpick rotates clockwise, because the earth's rotation in the northern hemisphere seems to be counter clockwise. In the southern hemisphere, the rotation is opposite to that in the northern hemisphere.
2, According to this phenomenon, people can prove that the earth is rotating by analyzing the direction of the projectile movement.
3. Gravity acceleration method
the earth is rotating all the time. Due to the effect of inertial centrifugal force, the ground gravity acceleration must be the minimum at the equator and the maximum at the two poles; The earth can not be a positive sphere, but must be a rotating ellipsoid with slightly bulging equator and slightly flat poles. The results of gravity measurement and radian measurement confirm the correctness of these views, and also confirm the earth's rotation from one side.
4. Deep well measurement
the earth rotates all the time, In order to prove this point, some people have carried out experiments in deep mines. The results show that the objects falling from the center of the well head always collide with the east wall of the mine at a certain depth, which proves the rotation of the earth from another side.
5, It was invented by French physicist Foucault in 1851. The earth revolves around its axis from west to East, and at the same time revolves around the sun. It is not difficult to observe the effect of the earth's rotation. A nylon fishing line without twist is used to hang a penlum, and a pointer is installed at the bottom of the penlum. The length of the penlum ranges from 3 meters to 30 meters. When the penlum is still, on the ground below it, fix a piece of white card paper and draw a reference line on it. Pull the penlum apart in the direction of the reference line and let it swing back and forth. After a few hours, the swing plane deviates from the original reference line. This is the phenomenon that the ground below the penlum rotates with the earth
e to the rotation of the earth, the rotation direction of the swing plane is clockwise in the northern hemisphere and counter clockwise in the southern hemisphere. The rotation period of the penlum is 24 hours at the two poles, and the Foucault penlum does not rotate at the equator. At latitude 40 ° 10 per hour ° Weak, i.e. one revolution in 37 hours
obviously, the longer the cycloid, the heavier the penlum, and the better the experimental effect. Because the cycloid is long, the swing is large. The period is also long, even if the swing is not more than several times (swing back and forth once or twice), we can also notice that the rotation of the swing plane, the heavier the penlum, the greater the swing energy, and the longer the free swing can be maintained. In the picture, the penlum part of Foucault's penlum hanging on the ceiling of the spherical exhibition hall of Beijing Planetarium rises in the East and falls in the West. This is the trajectory of the sun's apparent motion. The fact that the sun doesn't move is caused by the rotation of the earth
