What is the direction of the meridian? Why is the meridian north south?

The meridian direction is north-south. The ancients listed on the compass according to the earthly branch (Zi Chou Yin Mao Chen Si Wu Wei Shen Youxu Hai), just like the position of our watch 1 1 at 12 o'clock, the sub-direction is the north, the noon direction is the south, and the meridian direction is the north and south, so the hand of the compass is also called the meridian hand.

Corresponding orientation. The orientation corresponding to the ten heavenly stems.

A and B are oriental wood; C and D belong to the southern fire; E, self is ** soil; Geng and Xin are Western gold; Non and decay are northern waters.

The orientation corresponding to the twelve earthly branches.

Hai and Zi correspond to the northern water; Yin and Mao correspond to oriental wood; 巳 and noon correspond to the southern fire; Shen and You correspond to Western gold; Chen, 戌, Chou, not for the four seasons soil, corresponding to the southeast, northwest, northeast, southwest.

The meridian of the earth is also called the meridian, and the meridian is a group of lines connecting the north and south poles of the earth, so the direction from the five directions is the direction of the meridian, that is, the north-south direction.

In addition, the prime meridian refers to the meridian that passes through the Greenwich Observatory in the United Kingdom, and of course, it is also north-south.

The meridian direction is the north-south direction.

The meridian, also known as the meridian, is an auxiliary line hypothesized by human beings for the convenience of measurement, and is defined as a semicircular arc on the great circle line connecting the north and south poles on the earth's surface. Any two meridians of equal length intersect at the north and south poles. Each meridian has its corresponding numerical value, called longitude.

The meridian indicates the north-south direction.

In Feng Shui, what is the position of the meridian? - Zishan is due north, starting from degrees, ending at degrees, and the positive position is at zero degrees. Wushan is due south, starting from degrees and ending at degrees, and the positive position is at 180 degrees.

In Feng Shui, Zi is due north, and noon is due south.

The positive meridian direction of the house means the north-south direction.

The ancients combined the heavenly stem and the five elements to indicate the geographical position, and the mantra that circulated was: "Jiayi wood in the east, Bingding fire in the south, Gengxin gold in the west, non dehui water in the north, and ** Wuji soil." "The ancients also used the earth branch to indicate the geographical location.

China's architectural orientation should follow the laws of nature. The Northeast region is cold, and the hot axis should be used as much as possible, so the building orientation is auspicious in the direction of the hot axis, and the south-west is preferred. The south is different, the average temperature is higher, so it is better to avoid the hot sun and prefer the south-east.

The ancients carried out numerical positioning of different directions in the acquired gossip, and corresponded to the "nine directions such as the eight directions and the middle earth" and "the numbers 1-9", only the north and south directions, that is, the meridian direction has the largest difference between the numbers, the north is the minimum number 1, and the south is the maximum number 9.

The "meridian" direction of the house refers to the direction of the house, sitting south facing north or sitting north facing south.

From the perspective of Feng Shui, the "meridian" of the house is not good, and the "meridian" house cannot be bought.

It is said that there is a building in a certain community that sits north and faces south, with an empty front and a good view, and a tall building as a background behind it. At first glance, it is in line with the general pattern of the former Vermilion Bird and the rear Xuanwu, and good feng shui. The community invited a lot of feng shui gentlemen, and they all said that this house was good.

Why is the person in charge of the community keen to invite Mr. Feng Shui? It turned out that not long after the completion and delivery of this new house, all kinds of strange things happened. Among the dozens of buildings in the community, only this building has had accidents one after another, such as deaths, car accidents, and dismissal from work.

What exactly is the reason? According to the results of the Feng Shui test, although the three houses are completely parallel, the compass indicates a very different direction of the magnetic field, two of them deviate from the meridian line, and one house happens to be positive meridian. Mr. Feng Shui immediately concluded that the people living in this bedroom must be in turmoil, with constant internal and external troubles.

Except for the buildings (** buildings) and temples, the residential buildings cannot choose the meridian direction.

In the process of getting along with nature, people should try to avoid the sharp edge of "nature", reduce friction and confrontation, understand "nature" and adapt to "nature", which is a scientific attitude towards survival. ‍

Positive meridian refers to the direct rays of the sun into the room at 12 o'clock at noon, that is, whether the direction of the house is due south!!

Positive meridian refers to the direction due south. The positive meridian direction of the house means that the door points to the south.

I heard that the house of the meridian is only used by the temple.

Hello, the meridian direction is due south, I heard that it is not very good.

Radial tires refer to pneumatic tires in which the cord from one bead to the other in the carcass cord layer is arranged at an angle of approximately 90° to the tread centerline. The structural characteristics of radial tires are mainly manifested in the belt layer is the main stressed component. The belt layer and the carcass cord are arranged at a large angle (70 80), and the carcass cord and the belt cord cross from three directions to form an infinite triangular grid structure.

As a result, the crown stiffness is higher than that of bias tires, the number of ply layers is less than that of bias tires, and the sidewall is softer and lighter than that of bias tires. Radial tires are more wear-resistant and fuel-efficient than bias tires, and have good cushioning performance and high-speed performance.

Radial tires were invented in 1946 by the French company Michelin Tire. The internal cord weaving of this tire is arranged at a 90-degree angle to the center line of the tire combie, resembling the meridian on a globe. The top of the tire is equipped with a wire rope, which can withstand large internal compressive stress, the tread is not easy to deform, has good ground grip and stability, and is very suitable for high-speed driving.

At present, modern cars are equipped with radial tires.

Strengths and weaknesses of radial tires.

Because the structure of radial tires is different from bias tires, it has superior performance over bias tires:

1) Long service life. The radial tire has large rigidity and small circumferential deformation, and can be used as the tread material with hard rubber, so it has good wear resistance. And the tire grounding area is larger, the unit grounding pressure is small, the load is evenly distributed, and the slippage amount on the road surface is small, so that the mileage of the tire is about 50 longer than the bias tire.

2) Low rolling resistance and fuel saving. Because the radial tire cord layer is small, the friction between the layers is small, so its rolling resistance is 25--30 smaller than that of bias tires, which can not only improve the power of the car, but also improve the fuel economy, in actual use, the fuel saving rate can reach 6--8, and with the increase of vehicle speed, the fuel-saving effect is better.

3) Large bearing capacity. The radial tire cord is arranged radially, which can make full use of the cord strength and increase the bearing capacity of the bias tire by about 14.

4) Good adhesion performance. Due to the good elasticity of the carcass, the large ground contact area, and the less slippage of the tread, that is, the adhesion performance is good, which is conducive to improving the dynamics of the car. (5) Good vibration damping performance.

The radial tire carcass is softer than the bias tire, has good elasticity, and has good cushioning performance, which can improve the driving smoothness and ride comfort of the car, and can prolong the service life of the auto parts.

6) The tire temperature is low and the heat dissipation is fast. Because the number of radial tire cord layers is small, and there is no shearing effect between the cord layers, the friction is smaller than that of bias tires, the heat dissipation concealment is faster, and the temperature rise is low, which is conducive to improving the vehicle speed.

7) The tread is not easy to puncture and not easy to burst. The belt layer of radial tires is very strong, so that the tire can be punctured by nails and other things by about half. In addition, the strength of the cord is fully utilized, so that the tire is not prone to bursting under harsh use conditions.

The weakness of radial tires is that the tread and sidewall transition area and near the bead are prone to cracks, which have high requirements for materials and manufacturing technology, and high manufacturing costs. However, due to the obvious superiority of radial tires over ordinary bias tires, the application is becoming more and more common.

Large radial deformation, large lateral deformation, small circumferential deformation, small tire deformation under high-speed rotation, small strength.

It can be Zishan meridian, Bingzi, Bingwu gold, or Gengzi and Gengwu gold.

One of the two words meridian is determined.

The exact temperature is not felt.

Refers to the time of burial.

Meridian is the direction indicated by the earth's branch: Zishui is due north. The noon fire is due south. These two directions are yang.

Decay is the direction indicated by the heavenly stem: decay water is due north. Ding Huo shows the south. These two directions are yin.

The meridian direction is due north-south, and the Dingding direction of the mountain is a deviation next to the positive direction, not the most positive meridian direction of the mountain.
