At the beginning of 2 1 century, the G8 said in the Okinawa Charter of the Global Information Society held in Okinawa: "Information and communication technology is one of the most powerful driving forces for social development in 2 1 century, and will soon become an important driving force for world economic growth."
In fact, the understanding of ICT in the information and communication industry is not uniform. As a technology, it is generally understood that ICT can not only provide a variety of services based on broadband and high-speed communication networks, but also transmit and enjoy information. It is a universal wisdom tool. As for the extent to which business will be more, and the extent to which this tool will be "smart", the current concept is still very vague. Triple play is only a foundation and prelude of ICT, and IPTV and mobile TV are probably just the tip of the iceberg.
For fixed-line operators who have sounded the horn of transformation, ICT is now more regarded as a service provided to customers. This service is the combination and blending of IT (information industry) and CT (communication industry), and the communication industry, electronic information industry, Internet and media industry will all be integrated within the scope of ICT. Fixed network operators such as China Telecom provide customers with one-stop ICT services, including integrated services, outsourcing services, professional services, knowledge services and software development services. In fact, ICT services not only provide enterprise customers with solutions for line construction and network architecture, but also reduce the burden of enterprises in establishing applications, system upgrades, operation and maintenance, security and other aspects, and save the operating costs of enterprises, so they are welcomed by enterprise users. At present, the intersection of IT and CT is mainly reflected in the construction of IT enterprises' support system for operators. It is worth mentioning that BOSS (Business Support System), mobile is called BOSS, and China Telecom and China Unicom are called BSS.

Well, some people know the number of carats of diamonds. Carats, or carats, have been in use since 1907, when they were internationally recognized units of gem measurement. It is the quality unit of jade beads, diamonds and other precious stones, and the ratio of the purity of precious metals to [1]. 1. (weight unit of diamonds, etc. ) Carat (= 200mg) 2. The purity percentage is 24k. If it is 18, the purity is 18/24=75%.
Carat (ct), usually abbreviated as Ct, has been used as an internationally recognized gemstone measurement unit since 1907, which is the quality unit of pearls, diamonds and other gemstones and the purity ratio of precious metals. International standard 4C for evaluating diamonds. 4C refers to color, clarity, weight and cut. The word "Kela" comes from the Greek word "Kela", which refers to carobseed, a plant widely spread from East Asia to the Middle East. Because its fruit is said to have almost the same weight, and the weight of diamond is the most easily measured feature in 4c, the early carob tree was used as the weight unit of jewelry and precious metals. One carat is equivalent to the weight of a small horn tree seed. From 65438 to 0983, Mr. Tao of Chengdu Institute of Geology (now Chengdu University of Technology) conducted a specific study, which confirmed that Kela originated from the seed of carob in the Mediterranean region-rice bean, and the weight of this tree was about 200 mg, which had nothing to do with the weight of Robinia pseudoacacia, Pittosporum and Sophora japonica as some people said. It was not until the early 20th century that carat weight was standardized. 1 carat (ct)= 200 (mg)= 0.2 (g) 1 carat can be divided into 100 pieces, which can be used as a relatively small gem. Because the density of diamonds is basically the same, the heavier the diamond, the bigger the volume. The bigger the diamond, the rarer it is, and the higher the value per carat. The current metric carat unit, that is, 1 carat equals 200mg, was adopted from 1907. Before that, one carat was equal to 205 mg, or 0.205 g.
Edit this paragraph size
Carat (Ct) is the unit of mass (weight) of gemstones. Now 1 carat is equal to 0.2g or 200mg .. One carat is divided into 100 minute, such as 50 minutes or 0.5 carat, which is used to calculate smaller gemstones. Because the density of diamonds is basically the same, the heavier the diamond, the bigger the volume. The bigger the diamond, the rarer it is, and the higher the value per carat. Now 1 carat = 200mg = 0.2g. Klajo's 205.3mg is in the old gem book. If it is converted into the current carat, then one carat will be multiplied by 1.0265. This is only a rough description, because the carat value of different countries or regions in the old days is different. Diamonds weighing less than 1 carat are usually measured in "points", 1 carat = 100 carat. On the certificate of diamond, the weight of diamond is accurate to the third decimal place. IGI uses an electronic balance with an accuracy of 0.0000 1 carat to weigh the accurate weight of diamonds, and records it in the diamond appraisal report, accurate to two decimal places. So a 25 cent diamond weighs 0.25 carat. Diamonds of the same quality, the greater the weight, the more precious.
Edit this paragraph purity
Purity of precious metals (gold, silver, platinum, etc.). ) can be based on the weight ratio of "expensive" components to the total amount, that is, 24. Take gold as an example, pure gold is 24 k; 18K, that is, 18/24 is gold and 6/24 is alloy metal. X=24Mg/Mtotal, which can also be understood as: X/24=Mg/Mtotal X is the number of cards, Mg is the weight of precious metals, and Mtotal is the total weight.

Edit the price of this paragraph.
The price of a diamond ring is calculated in carats. Now generally 0.2 carat sells for about 4000 yuan; 0.3 carat sells for about 7000 yuan, and the bigger it is, the more expensive it is. A beautiful diamond depends on its purity, whether there are cracks, how many cracks, color, cut and so on. The price is related to the above points! Purity, luster, weight, size, color (the purer the better), exquisite workmanship, it is generally impossible to see that it is a diamond without polishing. If it is a handicraft, it depends on the brand, and it is good to have a high popularity. It should be noted that: 1 The higher the diamond grade, the greater the influence of weight on the price. 2. It is especially obvious for diamonds with critical weight. Such as: 30 minutes, 40 minutes, 50 minutes, 1 carat, etc. 3. National standards less than 0.2 carats are not classified. 0.2 to 1 carat can be classified by both loose diamonds and inlaid diamonds. Diamonds larger than 1 carat must be classified by 4C according to the classification standard for loose diamonds. The beautiful diamond ring proves sweet love. Since the diamond ring is the first choice for couples, what kind of diamond ring is suitable? Generally speaking, it is more appropriate to choose a diamond-encrusted ring below 50 points, which can not only express love but also be accepted by people of the general income class. A single diamond ring of 30 to 40 cents is a common choice for white-collar workers. Some rings inlaid with broken diamonds are also loved by some people because of their exquisite design. If economic conditions permit, it is best to choose diamonds with a score of more than 50, because diamonds with a score of more than 50 have considerable ability to maintain and increase value and have certain investment value. I remind you that while paying attention to the weight of diamonds, we must pay attention to the color, clarity and cut of diamonds, that is, comprehensively consider the "4c" standard. Diamonds with large weight, good cutting (bright light), few pure defects and white color are good diamonds. When buying diamond jewelry with a score of more than 40 points, don't forget to ask the merchant to show the appraisal certificate of the national testing department. In addition, it is suggested that when buying a diamond ring, it is best to buy earrings and pendants that can match it, so as to avoid regrets caused by improper matching of jewelry. Similarly, it is very appropriate for a woman to give her boyfriend a diamond ring as a token. Generally speaking, platinum plain ring with diamond ring is more suitable, simple and generous, gorgeous and unobtrusive, which properly shows the owner's good taste.
1 carat = 0.0002kg.
1 kg = 5000 carats
