Morphological characteristics of the cavity, trench, and so on accurate position, even to meet the assembly requirements, the entity can also print out the grinding, drilling, plating, etc. for further processing. Powder material is not limited to sand materials, as well as flexible scalable, high performance composite, investment casting materials to choose from. Due to the continuous progress of technology, the cost of 3D printer in many manufacturers, design institutes, universities, etc. to start or preparing to deploy, but their prices are still very difficult to be accepted by ordinary consumers. Fortunately, the 3D printer consumables cost is not expensive, does not become popular resistance. I believe that with the continued development of science and technology, the cost of 3D printer will continue to reduce, and ultimately into people's daily field office. The inspection of green laser pointer should be implemented step by step.
After more than half a century of research in the world, the voice recognition technology has been developed to close to the practical stage. In laboratory conditions, the average recognition rate of reading vocabulary continuous talk broadband speech signal can reach more than 90%. Level on the basis of voice recognition technology to try from a laboratory demonstration system to practical products. However, the voice recognition technology to enter a mature business use, there is still a difficult journey, must also be a breakthrough in many ways. Improve reliability. On the one hand, speech recognition technology need to be able to exclude the influences of a variety of acoustic environments. To use speech recognition in noisy environments must have special anti-noise (Noise Cancellation) microphone only.Although the application of fixed wireline phones and wireless mobile telephone networks have been widely spread to almost all sectors of society, but the telephone network is now the most important function is voice communication. If the combination of the two telephone network as the Internet Voice Portal, Speech recognition as the interaction of online information and convenient tools, you can in a fairly large range. Ethernet Virtual Private LAN technology (Virtual Private LAN Service, VPLS) is a network technology to solve different geographically remote IT infrastructure end-to-end communication, the technology has widespread applications, the market potential is huge, with very broad prospects for development.
