China's top economic planner approves highway project
BEIJING, Aug. 19 (Xinhua) -- China's top economic planning body said on Friday that it had given approval for an expressway in northwest China's Gansu Province, which will improve public transportation infrastructure.
The expressway will start from Jingtai County in the city of Baiyin, and end at Lanzhou Zhongchuan International Airport, stretching for 124 kilometers in total, according to a statement on the website of the National Development and Reform Commission.
The project is expected to cost around 7.93 billion yuan (about 1.2 billion U.S. dollars).
Central and local governments will be responsible for around 35 percent of the capital need for the project, while bank loans will cover the remainder.
The project is in line with the country's Belt and Road Initiative and will help promote local economic and social development, the statement said.

DVD recorder
A DVD recorder is an optical disc recorder that uses Optical disc recording technologies to digitally record analog or digital signals onto blank writable DVD media. Such devices are available as either installable drives for computers or as stand alone components for use in television studios or home theater systems.
As of March 1, 2007 all new tuner-equipped television devices manufactured or imported in the United States must include an ATSC tuner. The US Federal Communications Commission (FCC) has interpreted this rule broadly, including apparatus such as computers with TV tuner cards with video capture ability,videocassette recorders and standalone DVD recorders. NTSC DVD recorders are therefore undergoing a transformation, either adding a digital ATSC tuner or removing over-the-air broadcast television tuner capability entirely.[1] However these DVD recorders can still record analog audio andanalog video.Technical information
Detail of DVD-RW optics
Originally, DVD recorders supported one of three standards: DVD-RAM, DVD-RW (using DVD-VR), and DVD+RW (usingDVD+VR), none of which are directly compatible. As a general rule, however, most current DVD drives support both the + and - standards, while few support the DVD-RAM standard, which is not directly compatible with standard DVD drives.
Recording speed is generally denoted in values of X (similar to CD-ROM usage), where 1X in DVD usage is equal to 1.321 MB/s, roughly equivalent to a 9X CD-ROM. In practice, this is largely confined to computer-based DVD recorders, since standalone units generally record in real time, that is, 1X speed.
Recorders use a laser (usually 650 nm red) to read and write DVDs. The reading laser is usually not stronger than 5 mW, while the writing laser is considerably more powerful. The faster the writing speed is rated, the stronger the laser is. DVD burner lasers often peak at about 100-400 mW in continuous wave (some are pulsed). Some laser hobbyists have discovered ways to extract the laser diode from DVD burners and modify them to create laser apparatus that can cause burning.
