Bionic Boyfriend
In the reference materials, there was a novel plot related to the android boyfriend. For example, there was a story where the husband sympathized with his wife's hard work and spent a huge sum of money to customize a bionic robot. This robot actually became a special existence that interfered with the family relationship, as if it was a mistress in disguise. There were also some stories that involved the role of the androids in family relationships, emotional entanglements, and other plots. For example, a person who was thought to be a android was used as a substitute and was sent back to the laboratory to be destroyed. There was also a mention of a product similar to the concept of a robot boyfriend in real life. He was 1.82 meters tall, had 8-pack abs, could skillfully complete all housework, had a powerful AI chip and self-learning ability, had a gentle and considerate personality, and was very good at providing emotional value.

Operating procedures of the retina photography instrument
1. Basic operation:
- He connected the power source and turned on the power source, display screen, and printer.
- Use the mydriatic agent to dilate the pupils (for some cases where the pupils need to be dilated, such as color photography and ordinary photography, but there are also cases where the pupils need not be dilated), and turn off the indoor lighting.
- He guided the patient to sit properly and moved the external fixative target to guide the patient's eyes.
2. Color photography:
- Set the filter switch to "N".
- He adjusted the eyepieces so that the crosshair on the eyepieces was the clearest, aimed the light at the patient's pupils, adjusted the main body to the front and back, and illuminated the patient's eyes in a symmetrical manner.
- He set the angle of view, used the normal color camera buttons to adjust the illumination, and pressed the shutter.
3. Photomograph operation:
- The preparation and adjustments were basically the same as those for color photography. During the examination, the patient usually sat in front of the retina camera, with his chin on the jaw rest of the machine, and his forehead on the fixed ring. Then, he stared at the visual target in the camera to prevent his eyes from moving. After the camera focused, it automatically took pictures.
Different types of retina photography instruments (such as true color, focal, and ultra-wide-angle retina cameras) may have different operations, and different examination requirements (such as whether to dilated pupils, different photography modes, etc.) will also affect the operation process. For example, the ultra-wide-angle laser scanning glasses generally did not need to be dilated. The patient would focus on the target, and the machine would automatically capture the image of the eye.

Is it normal for the retina of the eye to reflect light?
It was impossible to say whether the strong reflection of the retina was normal or not. In some cases, this may be a normal phenomenon. For example, the reflection of the retina of a dog's eyes is a normal physiological phenomenon. The principle is similar to the reflection of a mirror under moonlight. The structure behind the retina will reflect the moonlight and let us see its eyes "glow". However, in the human eye, the increased reflection of the retina artery could be caused by many abnormal reasons. For example, high blood pressure could lead to hardening and narrowing of the retina artery, which would increase the reflection of the retina. Retinal damage caused by diabetes, such as retina disease, would also lead to increased reflection of the retina artery. Arteriosis would cause the inner layer of the artery to be thickened, causing narrowing of the retina artery and increased reflection. There were also diseases of the eye, such as epilepsy or yellowish degeneration, which could also cause the reflection of the retina arteries to increase. In addition, the membrane before the macula was a layer of fiber proliferating membrane covering the surface of the retina of the macula, which would enhance the reflection of the retina of the macula, just like tin foil. This condition could cause visual distortion, decreased vision, and a sense of flashing. Therefore, if you find that the retina of the eye has a strong reflection and is accompanied by abnormal conditions such as decreased vision and visual distortion, you should seek medical examination in time.

What are the contents of the novel fragments about the retina?
I recommend " Super Golden Right Eye ". The protagonist Li Zhuihua's right eye was blinded by accident and miraculously recovered its sight. It was also created by the mysterious coffin and light into a golden right eye. It could see through things, move objects, and have more functions. It was not difficult to appraise treasures, gamble stones, and see a doctor.
" Crossing the Foreignland with the Shurunyan " was not bad either. The young man brought the Shurunyan across the Foreignland and displayed all kinds of Shurunyan abilities one by one. Let's see how he would dominate the Foreignland. However, there were some problems with this book, such as the BUG in the Shurunyan, the ability settings, and so on. The ending was also a little rushed, but the early content was still worth reading.
The story of Uncle Zhang after he accidentally entered the immortal mountain in " mistakenly entered the immortal mountain " was very interesting, and the character information in it was also very rich.
One Piece: Tom the Cat's First Friend was super fun. The main character was stranded in the world of One Piece. His first friend was Tom the Cat, and there were many other characters that were summoned later on. The relaxed and funny style was very attractive, but there were some shortcomings at the end, but overall, it was worth watching.
" The Killing Intent of Man, The Reversal of Heaven and Earth " was a Xianxia novel. It had the flavor of a Chinese story. The protagonist was a chivalrous man in troubled times. The author had changed from a sports novel. Although it was lacking, it was very unique.

How is the retina examination done accurately in kindergarten?
There were many ways to check the retina. The more common method was to use an optometroscope to look at the bottom of the eye. This method could directly check the condition of the retina. Fundus photography was also a commonly used examination method. It was one of the commonly used examination methods in the field of optometriology. There were also some methods such as CT and A-scan that could be used to observe the retina. In addition, professors at the University of Hong Kong have developed a method that uses machine learning and artificial intelligence to scan the retinas of children under the age of six. High-resolution cameras and new computer software are used to analyze various factors, including the fiber layer and blood vessels of the eye. This method can help children detect retina-related risks early. The comprehensive use of these examination methods could improve the accuracy of retina examination for kindergarten children.

Eagle Bionic Plane
The Eagle Bionic Airplane was an aircraft that was inspired by the flight pattern and physiological structure of eagles. In the field of bionics, the flight characteristics of eagles provided many references for aircraft design.
For example, the NASA Ames Research Center in the United States invented the winglet based on the feathers on the eagle's wingtip when flying. This structure used the principle of bionics to reduce the induced drag of the aircraft. The " Go Go Bird 1000 " released by Hanwang Technology was a high-simulation flapping wing aircraft. It drew inspiration from the flight mode of eagles in nature. It was 46cm in length, 60cm in wingspan, and weighed 138 grams. It could fly for 12 minutes on a full charge and could fly up to 40 meters high. It could be set to fly freely or controlled by its self-developed flight control software. It had low-voltage automatic return, autonomous obstacle avoidance, fixed-altitude flight, straight-line flight, and specific flight. It had a variety of human-computer interaction control functions such as a sensory switch.
In addition, the research team of the Northwestern Polytechnical University continued to explore the field of bionic aircraft and made the world's longest flight time. There were also model enthusiasts who made highly bionic eagle aircraft, and even the People's Liberation Army revealed a bionic drone that looked like an eagle. Not only could it flap its wings and adjust its posture like a real eagle, but even the sound it made was no different from a real bird.
The novel " Hundred Years of Spaceship " is equally exciting. Everyone is welcome to click and read it!

Bionic design kindergarten
Bionic design had many applications in kindergarten.
From the perspective of space design, the amusement area could be designed with bionic furniture. Since most children were interested in cute little animals, the designers would simplify and transform the animal's shape, combining it with bionic features to highlight the fun. Through the simple lines and bright colors, it inspires children's imagination and imagination. The structure of this kind of bionic furniture did not need to be too complicated. As long as the shape and color met the aesthetic needs of children, it would be loved by children, leaving a deep impression on them and stimulating their love for life and nature.
In terms of teaching, there was a kindergarten science lesson with the theme of "interesting bionics". The purpose was to let children understand that some designs and inventions were made by imitating the characteristics of natural creatures, so as to stimulate children's interest in exploring nature and bold and innovative designs. The teaching process included showing pictures to inspire children to observe the relationship between the two, such as airplanes and birds, octopuses and suction cups, etc., so that children could understand the concept of imitation of the characteristics of natural creatures to invent. They could also communicate with children about other bionic phenomena, such as letting children guess which characteristics of natural creatures were imitated by cranes, wavy roofs, etc. Children were encouraged to imagine their own bionic inventions, and pictures of kittens and fish were provided for their imagination. The extended activities could also allow children to draw their inventions and tell them about them.
In addition, there was also a simple bionic small fish material bag suitable for kindergarten children to make by hand. It could be used in kindergarten science small production and help to cultivate children's hands-on and brain skills.
