After research for more than a decade, Beijing LP Code has pioneered new mathematics calculations and information technology codes to successfully develop China’s first Lots Perception Matrix Code (LP 2D Barcode) with complete intellectual property rights. It is fundamentally different from LP Codes developed in other countries, boasting higher performance and world-leading standards. Due to China’s late entry in development and use of 2D barcodes, the country had been using 2D barcodes developed by other countries. Because of the lack of core technologies, there are risks regarding intellectual property and information security. Now, the biggest advantage of Beijing’s new LP Code is its high level of security. It has low crack rate, which is exemplified by ‘null probability event’ statistically. Secondly, it has very high compression storage capacity. Its data storage capacity is four times that of Japan’s QR code, and five times that of USA’s DM. Thirdly, it has very strong error-correction capability. Whereas 2D Barcodes in other countries have maximum correction rates of 25% to 30%, Beijing’s LP Code has a rate exceeding 60%. Fourthly, LP Code is the only code using transformable code-based graphics symbols in the world. Prior to this, USA and Japan were the only two countries with international patents regarding 2D barcodes’ core algorithm. Beijing’s new LP Code has filled in the gap in China’s coding technology. It has also cemented new and reliable technological foundation in China’s developing Internet of Things industry.

An ordinary single-mode optical fiber achieves transmission capacity of 100.23Tb/s (equivalent to 1.2 billion people talking at the same time on a single fiber) at a distance of 80km. It is predicted that by 2030, global network traffic will increase by 1,000 folds comparing to that of 2010. Optical transport, the foundation for internet and communication networks, is facing increased pressure to handle huge amount of data. There is an imminent need to expand the network capacity. China’s single-mode optical fiber is operating at the C+L band carrying 375 channels, with 267.27Gb/s/channel large-capacity ultra-dense wavelength division multiplexing (WDM) transmission over 80 km. This is an important breakthrough, putting China in the global forefront in experimental transmission capacity of >100T. The experiments have broken the nation’s record regarding speed of optical transmission, and have solved some core technology problems relating to ultra high-speed and high spectral efficiency long-distance transmission system, including ‘high-order modulation, high spectral efficiency and non-linear effect suppression’. The breakthroughs have built the foundation for practical use of ultra high-speed ultra-dense WDM transmission over long distances. It provides the necessary technologies for China’s next-generation network infrastructure, as well as strong support to the nation’s broadband strategies and promotion of information consumption. The project is led by the Wuhan Research Institute of Posts and Telecommunications with participation from Huazhong University of Science and Technology, Fudan University, Beijing University of Posts and Telecommunications and Xidian University. It is a National 973 project June 2015 5 China Science and Technology Highlights by HKUST VPRGO Source: China News Date: November 7, 2014 named ‘ultra high-speed large-capacity ultra longhaul optical transmission basic research.’ Back to Top New Technology Enables Coalbed Methane to Become One of the “Hot” Energy Sources “With China being the world’s largest producer of coal, the country has rich coal and coalbed methane resources. The geological resource capacity of coalbed methane is comparable to that of natural gas. China has 13% of the world’s coalbed methane resource capacity, which is the world’s third after Russia and Canada,” said Wang Xiaokun, analyst of natural gas at Sublime China Information Group at an interview earlier. Coalbed methane is also known as ‘coal seam gas’. Its main component is combustible methane which is found in coal seams in coal mines. Coalbed methane, if not handled properly, can cause disasters in coal mines. It is possible to extract coalbed methane from seams of coal with new technology such that coalbed methane can act as an alternative to natural gas and benefit humankind. Nevertheless, the geological conditions of China’s coalbed methane are complicated. In Shanxi Qinshui Basin for instance, due to uneven distribution of subsurface coal seams underground, the directions in which coal seams head towards are inconsistent. During horizontal drilling, if the well being drilled fails to follow the direction of the coal seams, it may open towards the rocks, resulting in no gas but water. Moreover, coalbed methane, as an unconventional natural gas, has some characteristics similar to shale gas. There is no commonly used mining method. Methods used under diverse geological conditions differ. After a decade of R&D starting from 1997, Greka Group, which is responsible for developing part of Shanxi Qinshui Basin, has developed Lined Faulted Brittle Coal (LiFaBric) drilling technology (screen pipe technology in brittle coal seams) to solve the challenges posed by China’s diverse geological conditions. The technology involves directly drilling the well’s horizontal branches into coal seams. It will not be influenced by uneven distribution of coal seams. If the drill meets faults, it will be able to pass through them and follow the direction of coal seams. This ensures to a large degree that wells will open towards coal seams. Lowering screen pipe into the well after drilling will help to prevent coal seams from collapsing. This type of horizontal drilling technology only requires that a well can be drilled for 1km or more. Unlike other technologies, it does not require multiple vertical wells to be drilled. It requires small land surface and causes little pollution. No chemical agents are needed during the entire drilling process. There is almost zero pollution to coal seams. Moreover, PVC screen pipes are used and they have little negative effects on future coal mining. Upon completion, the land previously occupied by LiFaBric’s U-shaped well can be cultivated again, thus minimizing the land use.

It has been transported to China National Offshore Oil Corporation’s (CNOOC) LNG terminal in Ningbo, Zhejiang for onsite installation and is planned to undergo full-load testing by the end of 2014. This signifies the end of the long history of LNG core technology being monopolized by Japan. In the production process at LNG terminals, LNG needs to be gasified in order to pass through high-pressure pipes to be transmitted to power stations, industry users and urban households. IFV is the core device to complete gasification of natural June 2015 6 China Science and Technology Highlights by HKUST VPRGO gas. Its core technology had been monopolized by Japan for a long period, resulting in high cost and difficulties in maintenance. It is thus crucial to China’s energy development for the nation to master this technology, which will help to meet pressing internal market needs and avoid playing a passive role in the global market. Fenghua started independent R&D of IFV. In 2012, the project became listed in municipal-level science and technology plans and received RMB 700,000 funding support. After years of effort, China developed its first LNG IFV with international standards. Fenghua became China’s leading corporation in design of pressure vessels. As China continues to build LNG terminals, the IFV market is promising. IFV will also become an important driver for the economic growth of Harbin.
