Our life is increasingly inseparable from "technology". A little digging, a lot of food, clothing, housing and transportation are related to technology. People who pass by casually always carry mobile phones, various IC cards or MP3 walkman ... Even the most common buttons will find some shadows of the latest technology. Cruise ships in West Lake will be equipped with GPS positioning system. This high-tech thing will be installed on the cruise ship. If the ship is in danger, as soon as you call for help, the water command center will immediately find your exact position through the GPS system, and rescuers will arrive at the fastest time. (See "City News" on April 20) But this statement was made last year, and it is not too late now. Personalized stamps have flourished in the past two years, but personalized IC cards with much higher "technology" content than personalized stamps are not so lucky. Hangzhou people should be proud of personalized bus IC cards. Only 1 ,000 copies were sold in three years (see 1 April 7, 2008, City News). There are 1 day in three years, that is, there are 1 cards on average that cannot be sold. And the same ordinary bus IC card issued nearly 800,000,800,000: 1000, which is a bit embarrassing. The market votes with its feet. If you have enough reasons to make people like it, I believe people in Hang Cheng will not refuse technology to join their lives. It seems that this technology needs to be more practical.

Clothing-T-shirt made of nano-particle mixed fiber of a certain mineral can release negative ions for a long time and make people feel fresh after wearing it. This is the magical function of nano-clothing. Shanghai Donghua University applied nanotechnology to fiber, and developed a variety of "nano-clothes" with anti-ultraviolet, anti-bacterial, warm-keeping and moisture-conducting functions, and many enterprises began to produce and sell them.

Food-a new plastic made of nanotechnology can be used to make "antibacterial" tableware, which is not only non-toxic and harmless, but also automatically degrades after being discarded.

High-tech is the necessity of the times. The ideal state must be that high technology brings more convenience and comfort to people's lives. For example, the kitchen utensils in the future are all integrated special appliances-there are machines for washing and cutting vegetables, and there are also machines for automatic cooking. The degree of automation is so high that you only need to provide raw materials and seasonings, and then press the relevant menu button to wait for dinner. In the future, the washing machine will quickly dry clothes in a special drying box after washing and drying. The appearance of these new products will change human life with explosive revolution. The comfort, beauty and joy of people's lives will reach an unprecedented new realm. Let's see what the future home appliances will look like. Ultra-small bathrooms Small bathrooms are rare, but all on the market are showers. There is no small bathroom with a bathtub. So someone whimsically designed this ultra-small bathroom with multiple functions. First of all, when not in use, it is just a sink, but when it is used, the box next to it can immediately become a bathtub! At the same time, it is also equipped with a few unkempt little heads. I have to admire the designer's toughness, so strange things have been thought of by him.

High-tech bulletproof vest unveiled. Military uniforms show military power and represent the image of soldiers. Soldiers not only want their uniforms to be powerful and straight, but also want them to be invulnerable, rain or shine ... Sure enough, at the exhibition, the reporter saw this magical uniform that combines a variety of high technologies-the famous China new bulletproof vest and helmet. This single soldier bulletproof equipment adopts high strength and high modulus polyethylene fiber. This kind of fiber is a high-tech product that appeared in the early 1990 s and ranks among the three high-tech fibers in the world today. The strength of this fiber is 12 times higher than that of high-quality steel wire with the same diameter, but its weight is only1/8; Its outstanding characteristics are: strong, light, soft, tough, waterproof, moisture-proof, corrosion-resistant, and can be immersed in seawater for a long time without corrosion; It can also resist strong ultraviolet radiation. A new type of soft body armor made of this fiber is as thin as paper and as tough as steel, and it can also float in water. The lightweight bulletproof helmet made of it not only has the characteristics of the original bulletproof helmet, but also has new advantages such as sun resistance, radiation protection, comfortable and cool wearing, and no rebound injury when hit by bullets. China's new individual bulletproof equipment has broken through the general level of traditional bulletproof equipment and bayonet penetration, and is moving towards a more humanized high level.

The computer measures your feet and orders shoes for the first time, scans your feet into the computer, and then customizes your shoes according to the relevant data of your feet displayed by the computer. Canada's VORUM last Research Company gives you a chance to experience for yourself. The reporter put his right foot on the "three-dimensional laser scanner" and saw the indicator light on, and a red line slowly swept the reporter's foot. Soon, the reporter's "feet" have entered the computer. With a click of the mouse, many data such as the size, width, thickness of the foot and the size difference between the left and right feet 10 are quickly displayed. According to these data, the booth staff immediately selected a shoe from the sample shoes of various sizes next to them. The reporter tried it on. Not too big or too small. It really fits and feels comfortable. Using this advanced method of measuring feet to make shoes for the army can save a lot of time and resources, because making a basic template according to the accurate data measured by computer and then making shoes according to this template will naturally greatly improve efficiency.

The viability of a warm "field home" is combat effectiveness. Improving the battlefield living environment of officers and men is equivalent to improving the combat effectiveness of the army. A soldier's "field home" should be both sheltered from the wind and rain and warm and comfortable. In the camping equipment exhibition area, the reporter saw a propaganda film introducing a new type of heater: "In the environment of -20℃, a light plateau heater can raise the temperature in a tent of tens of square meters to 20℃ in 20 minutes, turning the tent into a warm and harmonious home." In this warm home, the soldiers can not only sleep well, but also live comfortably. You see, a small camouflage tent with a shower head has been set up on the stand of China Optical Group. It is reported that this portable shower weighs only 35 kilograms and can be carried away by two soldiers. No matter how remote your post is, 15 minutes can take a hot bath. Answer supplement

Generally speaking, high technology is the frontier science and technology with talent-intensive, knowledge-intensive, technology-intensive, capital-intensive, risk-intensive, information-intensive and industry-intensive, which has strong competitiveness and penetration and has a great impact on the development and progress of human society. The popular understanding is that high technology must be industrialized in order to form industrial scale benefits! And high technology has no borders! Need global high-tech industries to jointly cope with the common destiny of mankind! The "high" of high technology is relative to conventional technology and traditional technology, so it is not a fixed concept, but historical, developmental and dynamic. Today's high technology will become tomorrow's conventional technology and traditional technology. It is predicted that in 50-60 years, only 1% of the technology and knowledge people use today will remain, and 99% will be outdated. ● From the development of high technology in the world, high technology is not a single technology, but a new technology group at the forefront of science, technology and engineering. Each component of this group influences, complements and promotes each other. At the same time, because high-tech and high-tech industries are linked, it is also a production system integrating science, technology and production, which is strongly promoted by the market.

In addition, high technology is also different from the so-called "accumulation of experience" in the general sense of science and technology. It is not accumulated experience, but technology based on scientific discovery or creation. ● High-tech is mainly reflected in eight highs: high difficulty, high technology-intensive, high capital-intensive, high knowledge-intensive, high speed, high competition, high risk and high efficiency. Low high-tech is not mysterious, high-tech is actually around you. High-tech is people-oriented, and high-tech is the display of human wisdom. The high-tech wave that is impacting us is impacting and changing all fields of human social life, and it is also impacting this point and shocking everyone's heart. High-tech concerns everyone, and everyone cares about high-tech.
