Today viewpoint

　　Aerospace gives people a special feeling of "high cold", which reminds them of advanced fighter planes and magnificent space stations that ordinary people can’t see, touch or use.

　　A few days ago, the well-known American website "GOBankingRates" took stock of 25 kinds of technologies originated from the National Aeronautics and Space Administration (NASA) in our daily life, which spread all over our "food, clothing, housing and transportation". They come from the distant sky, but they are convenient for our daily life.

　　Food: baby milk powder, freeze-dried fruit, food safety packaging.

　　At present, more than 90% of infant formula in the United States contains microalgae. It was originally the product of NASA research, the purpose of which was to test the potential use of algae as an oxygen "recycling agent" in space travel.

　　Freeze-dried fruit is a common snack. However, the purpose of NASA’s development of freeze-drying technology is to make the fruits in the Apollo mission easier to carry, and this technology can maintain 98% nutrition with 20% quality.

　　In order to ensure the safety and quality control method of space flight food development, NASA has now become a food industry standard to protect the food safety of consumers all over the world.

　　Life: memory foam mattress, scratch-resistant lenses, anti-ultraviolet sunglasses, cordless vacuum cleaner, Nike air-cushion sports shoes, space blankets, ski boots.

　　Comfortable memory foam mattress can fully fit the human body and relieve stress, which is necessary for many families. Memorable foam was not originally used to make mattresses. It was originally developed by NASA to cushion the impact of spacecraft landing on astronauts.

　　Compared with ordinary glass, scratch-resistant lenses have a longer life. In fact, the scratch-resistant coating is a "by-product" accidentally discovered by Jet Propulsion Laboratory (JPL) under NASA when researching the diamond hard coating for aerospace.

　　In 1980s, two scientists from JPL developed a kind of welding glasses, which can absorb, filter and scatter the strong light emitted during welding. Later, this technology was widely used in anti-ultraviolet sunglasses.

　　Initially, Black&Decker was ordered to develop a portable device for Apollo and Gemini missions, which was used to extract samples from below the surface of the moon. This technology has been improved to become a "cordless vacuum cleaner".

　　Nike air-cushioned sneakers use the patent of "Blow Rubber Molding" obtained by M. Frank Rudy, a former engineer of NASA. The initial application target of this technology is spacesuit.

　　The space blanket is insulated and heat-preserved, which is an essential item for survival in the wild and marathon. But it was originally developed by NASA to protect spacecraft and astronauts at low temperatures.

　　In addition, the technology used by NASA in the joints of spacesuits has been improved and used in ski boots, which improves the athletes’ control ability in skiing.

　　Home: swimming pool purification system, household heat insulation materials.

　　In order to resist the extremely low space temperature, NASA made an insulating material called "radiation barrier" from aluminized polyester. According to JPL, aluminized polyester is now used in most household insulation materials.

　　In 1960s, NASA developed an electrolytic silver iodide filter to provide clean drinking water for astronauts, and now it is widely used to purify swimming pools.

　　Travel: aircraft deicing system, precision GPS, anti-skid groove on highway, better tires.

　　According to NASA’s technology transfer plan, civil aircraft can fly in cold weather, mainly due to a thermoelectric deicing system called Thermawing developed by NASA.

　　Many mobile phones are equipped with precision GPS technology developed by JPL, and its data comes from JPL global GPS receiver network. Even if there is no wireless connection, you can still use GPS positioning on your mobile phone.

　　NASA’s Langley Research Center has developed anti-skid slot technology to prevent aircraft accidents on wet runways. Later, this technology was widely used in expressways.

　　In 1970s, Goodyear Company developed a new tire material for NASA Viking Mars probe, which was used in parachute system. This technology was later used to improve ordinary tires, increasing their life by 10,000 miles.

　　Electronic products: mobile phone camera, notebook computer, high-power solar cell, wireless headset, mouse, CAT scanner.

　　In the 1990s, NASA asked JPL scientists to make a miniature camera that can be installed on spacecraft while ensuring the quality of photography. According to JPL, one-third of mobile phone cameras now use this technology.

　　According to the Smithsonian National Air and Space Museum, "Grid Compass" is the first notebook computer in the world. It was first used in the space shuttle mission in 1983, which is one of the inventions of NASA.

　　The crystalline silicon solar cells used in the home originally came from the lightweight solar energy system developed by the Environmental Research Aircraft and Sensor Technology Alliance under NASA for electric aircraft.

　　NASA has developed wireless headphones for astronauts to facilitate their communication. Now this technology has entered thousands of households.

　　According to JPL, a NASA researcher developed a computer mouse in the 1960s, which allowed users to operate on the computer screen and made the computer more interactive.

　　JPL initially developed a CAT scanner to scan aerospace components to get advanced digital images to detect defects. Now, it has become a commonly used medical instrument.

　　Medical care: cochlear implant, invisible dental appliance, ear temperature thermometer.

　　Adam Kiser, an engineer at Kennedy Space Center, used his working experience in electronic, sound and vibration sensor systems in the space shuttle project to develop early cochlear implants by using electric pulses instead of sound amplification technology.

　　Compared with the traditional metal appliance, the invisible dental appliance is more beautiful. It is made of transparent polycrystalline alumina, which was originally developed by NASA to track heat-seeking missiles.

　　Nowadays, many parents use ear thermometer to measure the temperature of sick babies or young children. According to JPL, this thermometer adopts infrared dissection technology invented by NASA and Diatek.

　　There is always one of these 25 technologies that you have seen, touched and used. Aerospace technology can not only be used in high space, but also improve our quality of life after landing, which is one of the driving forces for human beings to explore and fly higher and farther.

　　(Science and Technology Daily, Beijing, July 8 th)

　　At this year’s Beijing Auto Show, Chevrolet revealed some information about Transformers 4: Extinction and Rebirth (hereinafter referred to as "Transformers 4"), which will be released in China on June 28th. I guess there will be a large number of "Transformers" blasting cinemas at that time. It is said that the lineup of robots changed to 4 is larger, adding the role of robot dinosaur. The role of autobots has also increased, and Chevrolet has participated in almost all of them. Of course, there are also European luxury car brands, but most of them are crazy characters. Fortunately, there is a self-owned brand car in China, which you will understand after reading the following. Ok, without further ado, let’s take a look at what new roles will appear in Change 4.

　　◆ The exposed new role of autobots.

　　First, two new roles-Chevrolet Mai Rui Bao and Trax Chuangkuo

　　　 Predictive role: it may be fanaticism.

　　According to the latest trailer, the Chevrolet Mai Rui Bao and Chuangkuo SUV were added to change 4, among which Mai Rui Bao was pitiful and was cut in half by a robot, which reminded me of the Audi R8 that changed 2, and it was the same fate. Nevertheless, it can’t be judged that Mai Ruibao’s role is 100% crazy, because the hacker looks ferocious, so Mai Ruibao’s role may be an autobot assistant.

　　In addition, Chevrolet Chuangkuo SUV has also assumed a new role of changing 4. The transformation of this character appeared in the "Chevrolet Night" at the Beijing Auto Show not long ago. The face of this robot looks more like a fanatic. At present, it is rumored that it is playing a fanatic mixed soldier Vehicon, which is not heavy, but it can’t be underestimated in promoting cool.

　　Chuangku was released in China on April 19th. The car is positioned in a small SUV, equipped with a 1.4T turbocharged engine, with a maximum output of 103kW and a peak torque of 200 Nm, matching a 6-speed manual or automatic gearbox. The price range is 119.9-159.9 thousand yuan.

　　Second, Chevrolet Sonic RS (Aiweiou RS) rally modified version

　　　 Predictive role: it may be a small role of autobots.

　　Chevrolet Sonic RS is actually a domestic Aiwei European model. Sonic RS is a high-performance version of ordinary Sonic, equipped with a 138-horsepower 1.4-liter Ecotec turbocharged engine with a peak torque of 200 Nm, matching a 6-speed manual transmission. The Sonic RS of Change 4 has been modified in the style of rally car. At present, I don’t know what role it plays, but I think it should be as funny as "Skids" and "Mudflap" in Change 2.

　　3. 1967 Chevrolet Camaro SS/ Chevrolet Camaro Concept Car

　　　 Predictive role: Bumblebee

　　Bumblebee is a character who likes to be with people, with average ability and small size. In the G1 cartoon, the bumblebee turns into a yellow beetle. But in the movie version, it is a yellow Chevrolet Camaro, which is quite uncomfortable. However, after a long time, I gradually feel that Comalo is also quite suitable for playing bumblebee. At least when I see yellow Comalo occasionally in the street, I can’t help but exclaim "Bumblebee!" .

　　The bumblebees in episodes 1-3 of the Transformers movie version are all different, and they have all been modified to varying degrees. The bumblebee in Change 4 uses two different Camaro models, one is the 1967 version, which has been modified and equipped with a pair of big tires, and the wheel eyebrows are also protruding outward, which looks very muscular.

　　The other is the latest Chevrolet Camaro concept car. The new shape is different from the current Camaro. The front grille and "eyes" are narrowed into a seam, which looks slightly introverted. The visual center of gravity moves down from the air grille above to the bumper air intake, which is also more dynamic. Change 4 should be in addition to change 1, once again using different generations of Comalo to play bumblebee.

　　Fourth, the modified Chevrolet Corvette C7 Stingray

　　　 Predictive role: Heng Pao.

　　Heng Pao also appeared in the first two Transformers movies, when the prototype car was a concept version of the Corvette Stingray. The reasons for adopting Stingary may be as follows: First, C6 will be replaced, and Chevrolet is unlikely to use C6 as a new image; Second, the G1 version of Heng Pao is already very cool, and Chevrolet needs to use the latest models to match the role, so it adopts the concept version of Stingary. But now that C7 has come out, it is estimated that Chevrolet will definitely advertise in the movie. Therefore, this modified version of Corvette C7 Stingray may replace the concept version of Stingary as the new prototype of Heng Pao.

　　In G1 version, Heng Pao turned into a red Lamborghini Countach LP500-2, which was very cool in 1980s. I believe that many post-80s people didn’t know there was such a sports car named Lamborghini until they met Transformers.
