[Photo/Xinhua] BEIJING - China has successfully designed and tested its first drone-carried dropsonde, or meteorological data monitor, to carry out meteorological observations. The unmanned aircraft vehicle (UAV) will carry the dropsonde and drop it at an altitude of 6,000 meters to measure atmospheric profiles as the device falls to the ground. Launched using a parachute, the dropsonde can descend at a stabilized speed and cut the atmosphere column like a scalpel to gather data such as temperature, humidity, and wind direction and transmit them to ground receiving devices in real time. The dropsonde carried by UAV was produced by the Second Institute of China Aerospace Science and Industry Corporation Limited (CASIC) and the test was run and monitored by the Meteorological Sounding Center of China Meteorological Administration (CMA) in May. The drone-carried dropsonde is an essential payload for aircraft meteorological sounding, which is more targeted than weather balloons and applied in much wider fields than rocketsonde, said Zhang Xuefen, a researcher at the CMA. Such dropsondes are small and light and have a high accuracy when applied. Once equipped with a power cord and data wire, these dropsondes can be hung from any part of a drone's wing, belly or cabin and work stably and reliably between 70 degrees Celsius and minus 90 degrees Celsius. According to the CASIC, drone-carried dropsondes can be widely used in meteorological emergency, disaster and ecological monitoring and offer a convenient and low-cost option for artificial meteorological observation and response systems in the future. wholesale rubber braceletsusb wristbands customtwenty one pilots rubber braceletevent wristbandsrubber bracelets canada
Moves to improve conditions for HK people on mainland boost city's integration with national development. Li Bingcun reports. A year after the nation's top leader Xi Jinping made his first inspection tour of Hong Kong as president, a series of measures have been rolled out to help the city's development and livelihood issues. Those efforts came after Xi outlined the central government's support for Hong Kong's integration with the country's overall development. In his speech on July 1 last year, during the three-day inspection tour, one of the strongest pledges Xi made was to help people from the city who wanted to study, work and live on the mainland, offering more opportunities for Hong Kong compatriots seeking development opportunities. Later, in August and December last year, the Hong Kong and Macao Affairs Office of the State Council announced two batches of measures offering convenience to Hong Kong people on the mainland in education, employment, business and travel. The most timely and helpful measure is phasing out the employment permit requirement for Hong Kong people working on the mainland, explains Kuo Wai-keung. Kuo is a Hong Kong-born entrepreneur operating a startup in Qianhai, a free-trade zone in Shenzhen which is the first area to implement the new policy. An employment permit mechanism has been imposed on residents from the Hong Kong and Macao special administrative regions and Taiwan since 2005. The permit, a must for people from the three places to work on the mainland, should be renewed every two years. Kuo said the change meant the company's Hong Kong employees no longer need to extend their work permits when their contracts expire. Time needed to recruit new staff from Hong Kong has been reduced by at least two months. The change significantly dismantled a major obstacle for Hong Kong people seeking to pursue careers on the mainland, Kuo said. I believe this will encourage more from Hong Kong to take their first step in the huge market, he added. Similar measures included a national administrative order to give Hong Kong and Macao people equal rights to the mainland's housing fund. Zhuhai - a Guangdong-Hong Kong-Macao Greater Bay Area city - responded this month, by allowing Hong Kong and Macao people who work in the city to join the Housing Provident Fund system, making them eligible for low-interest housing loans. Moreover, the education authority set up scholarships dedicated to students from Hong Kong and Macao to sponsor their studies on the mainland, with larger quotas and more money. The National Social Science Fund is now also open to applicants from Hong Kong and Macao.
