China’s charity sector has been developing quickly under the support of the internet. Currently, more than 80 percent of charitable money of foundations comes from the internet, said an official with the Ministry of Civil Affairs.

Last year, 28 million donors donated more than 830 million yuan online on the 99 Charity Day, an annual online donating event on Sept. 9 initiated by the Tencent Foundation in 2015.

Last year, about 8.46 billion clicks and donations were made on 20 fundraising platforms designated by the Ministry of Civil Affairs, according to Jia Xiaojiu, director of the ministrys charity promotion and social work department.

Li Bo, inspector at the department, said the ministry has enacted relevant documents to guide and regulate online charity. It has established a credit blacklist of those who are involved in misconducts.

Watching a giant rocket blast off and roar heavenward is an unforgettable experience for most people. But for those located far from the launchpad and under the path of trajectory, rockets are a source of concern as debris might fall to the ground.

Chinese engineers have begun developing a technology that will help minimize hazards for those below a carrier rockets trajectory and also enable rockets to be reused, according to project leaders at the China Academy of Launch Vehicle Technology, the countrys major carrier rocket maker.

During Chinas latest rocket launch on Friday from Xichang Satellite Launch Center in Sichuan province, researchers from the academy conducted the countrys first successful controlled-descent test of a major part of the rocket, He Wei, a senior rocket scientist, said on Sunday.

They installed a set of devices known as grid fins锛峟oldable, adjustable heat-resistant wings锛峛etween the first and second stage of a Long March 2C liquid-propelled carrier rocket.

After the 23-meter-tall first stage burned up its fuel and separated from the second stage, the grid fins were unfolded and began to steer the first stage as it fell back from the edge of space through the Earths atmosphere, He said.

The scientist said that thanks to the grid fins, debris from the first stage returned to a designated area in Guizhou province, adding that the test showed that China has become the second nation after the United States to possess controlled-descent technology for carrier rockets.

Cui Zhaoyun, deputy chief designer of the Long March 2C, said Fridays test was a challenge for researchers of the grid fin because compared with small rockets, it is more difficult to fulfill controlled reentry of large models like the Long March 2C.

Xing Qiang, founder of Micro-Rocket Union, a nonprofit space research organization in Beijing, said that grid fin technology has been widely adopted on carrier rockets and weapons such as ballistic missiles for a long time. But before Fridays test, it had only been used by the US SpaceX for controlled descents.

SpaceX engineers use grid fins, together with other apparatus, to make their Falcon 9 series rockets reusable.

Compared with traditional fins on rockets, grid fins feature better aerodynamic efficiency and allow the rockets debris to conduct controlled descents, he said. The type used by the Long March 2C rockets is very difficult to design and is a true test of designers know-how in aerodynamics and rocket structure.

As China has become one of the biggest users of carrier rockets, finding solutions to the safety hazards caused by an uncontrolled fall of rocket debris is being prioritized on researchers agendas.

Currently, people in potential rocket debris areas are evacuated to safe places during each launch mission.

BEIJING, July 27 — Youth from China and the United States displayed their innovative projects at the 2019 China-U.S. Young Maker Competition and called for further exchanges and cooperation in innovation.

Organized by the Ministry of Education, the competitions final award ceremony was held Friday in Beijing. Among the 10 grand prizes, seven went to Chinese teams.

The winning projects focused on areas of community development, education, environmental protection, health and fitness, energy, transportation and other areas of sustainable development.

Damen Wilson, an undergraduate student from Purdue University, led a team and won a grand prize in the competition for a device that can be used to treat a type of vertigo.

The wearable device named Verti-Fix can track the motion of vertigo patients heads and provide feedback to the physicians with ease. It can also be used in home self-treatment with patients.

We will target the products toward the elderly, of which the market is huge and will grow due to the longevity of human life and the increasing population, Wilson said.

The competition has been held annually since 2014, serving as a platform to enhance exchange and friendship between Chinese and American young people and to unleash the innovative and entrepreneurial spirit.

Wilson told Xinhua it is exciting to interact with the bright young people in China and see what youth from the United States are making in comparison with the Chinese youth.

Young Chinese and American makers are full of innovation spirit, he said, adding that their intention to utilize the products to contribute to public interests is impressive.

Chinese student Zhang Huanyu, together with her team, invented an intelligent device to help deaf students communicate in classes using gesture and infrared recognition.

In addition to creativity, many projects at the competition are very practical and thus attract the attention from investors and enterprises, said Zhang, adding that it offers valuable opportunities for subsequent incubation.

China is now further boosting mass entrepreneurship and innovation, and actively integrating into the global innovation network.

At present, a total of 29 universities and institutions set up the exchange centers for young makers to foster a favorable innovation environment.

China and the United States have broad consensus and huge cooperation potential on the path of innovation, said Wilson, adding that he hoped young people in the two countries would jointly forge ahead to create more excellent projects.

BEIJING, July 28 — The following are the highlights of Chinas key technology news from the past week:

REMOTE SENSING SATELLITES

China successfully sent a group of new remote sensing satellites into orbit from the Xichang Satellite Launch Center in southwest Chinas Sichuan Province on Friday.

The satellites have entered the planned orbits, and will be used for electromagnetic environment detection and related technological tests.

PRIVATE COMMERCIAL CARRIER ROCKET

A carrier rocket developed by a Chinese private company successfully sent two satellites into orbit from the Jiuquan Satellite Launch Center in northwest China at 1:00 p.m. on Thursday.

The SQX-1 Y1, developed by Beijing-based private rocket developer i-Space, is a four-stage small commercial carrier rocket.

SATELLITE DATA IN FLOOD RELIEF

China has provided satellite data to assist India with its recent flood relief efforts, the China National Space Administration (CNSA) said on Wednesday.

The CNSA launched the satellite emergency response plan early last Thursday, following the Indian Space Research Organizations (ISRO) request for international disaster relief support last Wednesday night, under the International Charter on Space and Major Disasters, said the Chinese space agency.

BEIJING, July 28 — Tapping the window to surf online, automatic in-cabin temperature control, and real-time information on how crowded the subway line is.

MetroTrans 2019 in Beijing, the showcase of next-generation subway cars and technologies, drew together Chinas latest innovations such as advanced materials, artificial intelligence and cloud computing, depicting smarter and greener public transport of the future.

CETROVO, developed by CRRC Qingdao Sifang, was one of the most-anticipated subway cars at the exhibition. It is environmentally friendly with an intelligent design and top speed of 140 km per hour.

Chen Xu, one of the lead designers, said the CETROVO is 13 percent lighter than the average subway carriage with a carbon fiber composite body and frame. Its silicon carbide permanent magnetic traction system improves energy efficiency by 15 percent, and noise levels are 3 decibels lower.

A fully active suspension system bogie makes the ride exceptionally smooth.

Passengers can surf online via smart screens integrated in the windows, search information, browse the news and watch videos.

Meanwhile, the latest subway car from CRRC Changchun Railway Vehicles is powered by flexible solar panels and vehicle batteries, making it Chinas first solar-powered transit rail car.

On a display screen inside the cabin, real-time information tells passengers how crowded the carriage with blue is for comfortable and red for crowded.

Rail transit control system integrator CASCO introduced the fully automatic operation system 2.0 for smart subways. From wake-up in the subway yard to self-inspection to operation, washing and going dormant, the carriage can complete its daily routine without human intervention.

Meanwhile, as automatic train operation requires reliable information systems and networks, growth in subway lines and passenger volumes poses new challenges to information and communication systems.

Huawei introduced the Urban Rail Cloud and networking switches powered by HiSilicon chips. The switches, the size of four traditional computer cases, can meet the computing demand of the whole subway system.

This year is the 50th anniversary of Chinas subway officially entering operation.

According to China Urban Rail Transit Association, since Beijing Subway Line 1, Chinas first subway line, started operation in 1969, more than 6,126 km of urban rail lines – 76 percent of them subway lines – have been put into operation in 37 cities on the Chinese mainland.

The three-day MetroTrans 2019 wrapped up in Beijing on Saturday.
