“Mom, you see, the blood vessels in my hands are shining! If there is this machine, then I will never be afraid of injections again!†On December 28, 2017, one of the “artifacts†in the infrared blood vessel imager The child who had experienced before said pleasantly. Here is the scene of the event “Innovation Drives the Development of Science and Technology to Lead the Future - The Academy of Science and Technology Innovation Annual Tour 2017â€. In the afternoon of the same day, the tour officially kicked off at the Beijing Planetarium.
The exhibition tour was mainly based on the Chinese Academy of Sciences' "Initiative Action and Progress - Innovation Exhibition of the Chinese Academy of Sciences since the Eighteenth National Congress" and selected "deep space," "deep sea," "deep," "deep blue," "life science," and "ecology." Some of the eight aspects of “agriculture†and “big scientific installations†that are more easily understood by the public are presented through a variety of popular science methods. According to the organizers, the tour activities of the Beijing Railway Station will continue after the Spring Festival.
According to VR Network, this exhibition is sponsored by the Chinese Academy of Sciences, organized by the Bureau of Science and Communications of the Chinese Academy of Sciences and the Document and Information Center of the Chinese Academy of Sciences, and co-organized by the Beijing Planetarium, the Computer Network Information Center of the Chinese Academy of Sciences, and the Technology Industrialization Network Alliance of the Chinese Academy of Sciences.
RCA Cables can be used to connect a variety of audio and video devices, such as camcorders, to TVs or stereos to speakers. Most high-end camcorders have all three RCA jacks, so the signal entering or leaving the device goes through three separate channels-one video and two audio-resulting in a high-quality transfer. Lower-end camcorders usually have only one jack, called a stereo jack, which combines all three channels. This results in lower-quality transfers because the signal is compressed. In either case, RCA cables transmit analog, or non-digital, signals. Because of this, they cannot be plugged directly into a computer or other digital device. RCA cables connect amplifiers to all sorts of devices.

Quality of RCA Cables
Several factors affect the quality, price, and performance of RCA cables:
Materials: The connectors on RCA cables are often gold, silver, or copper. As you might expect, the gold connectors are the most expensive. They're also better than silver and copper connectors at preventing oxidation, but not as good at electrical conductivity. The silver connectors are best for electrical conductivity with the copper cables coming in a close second and the gold cables falling far behind. Other suitable materials are nickel, zinc, and tin.
Cable Length: Cable length has a negative effect on signal quality. Buy a cable that is only as long as you need it to make the connection for the best signal quality.
Shielding: A well-shielded cable delivers a better signal than one that lacks robust shielding.
The other end of the cable: If possible, match the material used in the other end of the cable to the material used in the connectors. Don't match tin with gold or silver with gold. Those combinations can cause problems because of an electrolytic reaction.
