Little Sparrow is going to the movies again. Although I want to change to a new taste today, I can’t resist the film "My Motherland and Me" which has the most films-it is understandable that it has gathered 7 well-known domestic directors, and the cast is also different. Kind of "counting stars"✨ (forgive me for thinking of a singing variety show on Mango Channel, seven directors handed in their homework at the same time, Little Sparrow felt like she was reviewing the propositional composition, Little Sparrow might be swollen).
Don’t talk nonsense, 7 homework in "My Motherland and Me", oh no, do you understand all the 7 short films? Even if there are some friends who do not understand, or have not yet gone to the movies, please check this short article Little Sparrow, it is absolutely dry!
"Eve": Details you didn't pay attention to-the original appearance of Tiananmen Square
This chapter accurately restores the appearance of Tiananmen Square at the founding ceremony. At that time, Tiananmen Square had red walls in three directions: east, west, and south, and the location of Huabiao was different from now.
In fact, these details have already appeared in the oil paintings of the founding ceremony, but because of the technical limitations of my country's film and television production in the early years, this scene could not be vividly reproduced. Therefore, our previous film and television works were unable to accurately represent the early Tiananmen Square. The whole picture.
This time director Guan Hu boldly reproduced the grand occasion of the founding ceremony of the year, indicating that the level of my country's film and television production has reached a new height.

"Encounter": What disease did Gao Yuan get? Why don't you recognize your blind date girlfriend? The
film only relies on a few detailed shots to show the storyline of the scientist Gao Yuan (played by Zhang Yi) who got sick because he rescued scientific research equipment. As for why you got sick? What's the disease? There was no explanation at all, so that the cinema was whispering, and the audience who did not understand nuclear physics looked confused. In the
film, a group of scientists are doing an accelerated nuclear test. Due to equipment problems, the nuclear accelerated reaction cannot be stopped. At the time of crisis, Gao Yuan (played by Zhang Yi) directly separated the nuclear material in the accelerated reaction by hand, keeping it beyond the critical distance, thus terminating the nuclear reaction process and avoiding an explosion.
Gao Yuan (Zhang Yi) directly touched the high-concentration nuclear materials with his hands. After being exposed to nuclear radiation, the mask was stained red with blood. Later in the hospital, he was lying on a sickbed with weakness, pale complexion and white lips. The military doctor said that he had very low platelets and there were a lot of naive cells in his blood. This is a typical manifestation of acute radiation sickness.
Patients with acute radiation sickness have obvious characteristics in the course of disease progression and are divided into four stages. In the initial reaction period, vomiting, nausea, fatigue, fatigue, and erythema may appear after partial exposure. Experienced nursing staff should prepare for disinfection of the ward to prevent infection. In the false recovery period, the patient's symptoms have improved significantly, showing a false recovery (Gao Yuan ran out of the hospital privately, perhaps at this stage), do not think that the patient has improved. Patients generally enter the extreme stage very quickly, which is also the most dangerous period. The extreme period is the period when the patient's psychological fluctuation is the greatest, and the psychological care of the patient must be done well. Under the protection of effective treatment measures, patients often enter the recovery period safely, and the blood picture gradually rises. After the white blood cell is greater than 1000, the laminar flow hood can be removed, and the patient can move out of the ward. After complete recovery, the patient must be followed up for long-term medical treatment. In the
movie Gao Yuan (played by Zhang Yi) was too close and was exposed to excessive doses of nuclear radiation. His health was extremely dangerous. He also ran out of the hospital privately to find out whether the atomic bomb test was successful and was infected with an outdoor virus, leading to his final death.

"Winning Championship": Antenna in the hands of Han Haolin, you You can also make one yourself! In the chapter of
"winning the championship", the plot has been developing around the antenna in the hands of the young actor Han Haolin. I guess my friends born in the late 1980s may have never seen this kind of antenna. The receiving antenna of
is called the "Yagi antenna". In the 1920s, it was invented by Hideji Yagi and Tashin Uda of Tohoku University in Japan. The
antenna has good reception performance against radio waves. In the 1980s, when the penetration rate of cable TV in our country was not high, a large number of radio enthusiasts used the method of querying information.This type of antenna is self-made for TV watching.

"Return": Are Blancpain watches expensive?
has the most watch scenes in the chapter of "Return". Ren Dahua plays a watch repairer in the play. His watch is a Blancpain antique Fifty Fathoms diving watch (Fat is a Chinese character, pinyin is xún, the total strokes are 15 strokes, meaning the unit of English length), It is the relic left to him by his father. In order to make it easier to check the time, Ren Dahua gave it to his wife, the Hong Kong policeman played by the actor "Hui Yinghong". In 1953, Blancpain's Fifty Fathoms Fifty Fathoms was born, slightly ahead of the Rolex Submariner in the same year and the Omega Seamaster 300 released in 1957, becoming the earliest dive watch.
In addition, the Blancpain that appeared in the play has a special place, with a "No Radiations" sign at six o'clock on the dial. At present, the value of this watch in the secondary market is high, at more than RMB 200,000. Of course, as a work of art, there are still some differences between the watch in the movie and the real Blancpain Fifty Fathoms. For the need of the plot, the Blancpain Fifty Fathoms calendar in the close-up shot directly jumped from June 30 to July 1. In fact, this Blancpain produced in the 1960s uses an ordinary self-winding mechanical movement and does not have a perpetual calendar function. Therefore, according to the law of mechanical structure operation, it should first jump to June 31, and then Manually adjust to July 1.

"Hello Beijing", I really didn't think about what to write...
"Day Meteor": Why do astronauts have to sit on a stool
In the movie, the Shenzhou 11 spacecraft The astronauts Jing Haipeng and Chen Dong always sat in their chairs after leaving the cabin. Why? In fact, this is all caused by weightlessness!
After returning to the earth, the astronaut must sit on the chair for the following four reasons:
1. The astronaut in space is in a weightless environment. Without gravity as a reference, the vestibular receptors in the inner ear are no longer in contact with surrounding neurons. The transmission of electrical signals to the central nervous system causes loss of the ability to distinguish between directions and neurological disorders. When you return to the ground, you will feel very light on the soles of your feet, and you may fall accidentally, just like you just finished a roller coaster. You will feel light and fluttering, and you will fall down at the first touch, so the astronaut must support and protect after returning to the ground.
2. Due to gravity on the ground, the blood in the human body will flow to the high head under the blood pressure. Without gravity in space, high blood pressure is not needed, and this function of forcing blood to flow to the head will be weakened. After returning to the ground, gravity recovers, but the ability to press blood to the head is too late to recover. Standing on the body will cause insufficient blood supply to the head, so you must sit down and wait for the blood circulation to recover.
3. In the weightless environment of space, astronauts cannot use muscles to support their bodies, and muscle atrophy will occur. Therefore, astronauts will have muscle atrophy after staying in the sky for a period of time. After returning to Earth, it is difficult to support his body and the space suit weighing tens of kilograms in a short time. After returning to the ground, the whole body feels limp under gravity, unable to stand on its own.
4. In the state of weightlessness, the human bones are not stimulated by mechanical stress, and a large amount of bone calcium in the astronaut's bones will be lost, causing osteoporosis. The lost bone is excreted through the kidneys, and the human body is prone to fractures. This is also one of the main reasons why astronauts have to take wheelchairs out of the cabin.
Then why do our astronauts have to make chairs instead of wheelchairs? The editor of
estimates that because our landing sites are all gravel ground, wheelchairs cannot be pushed...

"Escort": Song Jia said that he would come eight, what is this? In the
film, Song Jia said "8", which refers to raising the G value of the centrifuge to 8G. G value physics is also called "gravitational acceleration". The equipment used by
pilots for training is called a manned centrifuge. The centrifuge can realistically simulate the flight load. The simulation cockpit is equipped with aircraft control elements, visual scenes, etc., and the pilot can operate autonomously, providing the pilot with a sensory experience close to the real flight process.Achieved active pilot training.
8 G, which is equivalent to the pilot's body, which has to bear the pressure of 8 times his own weight (if you weigh 70 kg, the pressure at this time is 560 kg). Under such great pressure, pilots should not keep their minds sober and be able to control the aircraft. This is undoubtedly the biggest test of physical skills.
