Mars, known as "small earth", is the first planet outside the earth's orbit and is red in color. Because of the great change of brightness, it is called "fluorescence" in ancient China. In western ancient Rome mythology, it is compared to the "Mars", the God of war in the blood of the body armor.

In June, Mars was brighter than one day. The rising time was around 22:42 in advance. The sky was located in the South West before sunrise, and the observation conditions were very good at the latter half of the night.

Zhao Zhiheng, an astronomer and director of the Astronomical Society of Tianjin, said that at about 4 a.m. on the 3 morning, people who got up early in the morning would see the "month of deficiency" in the south of the south of the West in the 20th day of the fourth month of the Chinese lunar calendar. Near the left side of the moon, there is a red star that glitters. This is the famous Mars. The red moon and the bright moon are deep in the firmament, and add endless beauty to the dawn.

Astronomers warn that in addition to naked eye observation, astronomers will observe the "Mars conjunction" with small telescopes, and the effect will be even better. Through telescopes, Mars looks like an orange sphere, very beautiful. Interested citizens can also try to find the "polar cap" of Mars. There is a white covering area on the poles of Mars, which is the polar cap. The size and color of the north and south polar cap of Mars will vary with the seasonal changes on Mars.

I have heard that in order to reveal the mystery of Mars's atmosphere and water, human beings have successfully launched more than 20 Mars probes to Mars in the past forty years.

In order to see this spectacle, the little editor of Mao linear motor has already booked the alarm clock yesterday, and wanted to take you a look at the legendary "Star Moon Fairy Tale". Cough, like me, comrades who didn't see the landscape or go to search online, maybe they can see pictures taken by others.

The same LM linear motor has simple structure, high precision, high efficiency, high response, no maintenance, no alveolus effect, no need to change direction. The maximum precision of the repetitive positioning of the sound coil linear motor in Kunshan's autonomous R & D production can reach 0.1mm. It is especially suitable for short stroke, fast response and high precision closed loop servo control.

The linear motor has a series of advantages, such as infinite resolution, no lag, high response, high speed, high speed, small volume, good force characteristic and convenient control, so that it is more suitable for the control system which requires high acceleration, high frequency excitation, fast and high precision positioning. Modern disk drives, optical disk drives and some high-precision positioning system actuators are driven by the same linear motor.
